Infrastructure as a service ( IaaS ) is a cloud computing service model where a cloud services vendor provides computing resources such as storage, network, servers, and virtualization (which emulates computer hardware). This service frees users from maintaining their own data center , but they must install and maintain the operating system and application software. Iaas provides users high-level APIs to control details of underlying network infrastructure such as backup, data partitioning, scaling, security and physical computing resources. Services can be scaled on-demand by the user. According to the Internet Engineering Task Force (IETF), such infrastructure is the most basic cloud-service model. IaaS can be hosted in a public cloud (where users share hardware, storage, and network devices), a private cloud (users do not share resources), or a hybrid cloud (combination of both).

Under the iPaaS integration model, customers drive the development and deployment of integrations without installing or managing any hardware or middleware. dPaaS delivers integration—and data-management—products as a fully managed service. Under the dPaaS model, the PaaS provider, not

704-658: A cash-and-stock transaction valued at US$ 69 billion, with the End-User Computing (EUC) division of VMware then sold to KKR and rebranded to Omnissa. In 1998, VMware was founded by Diane Greene , Mendel Rosenblum , Scott Devine, Ellen Wang, and Edouard Bugnion . Greene and Rosenblum were graduate students at the University of California, Berkeley . Edouard Bugnion remained the chief architect and CTO of VMware until 2005 and went on to found Nuova Systems (now part of Cisco ). VMware operated in stealth mode for

792-451: A cloud platform instead of directly buying and managing the underlying hardware and software layers. With some PaaS, the underlying computer and storage resources scale automatically to match application demand so that the cloud user does not have to allocate resources manually. Some integration and data management providers also use specialized applications of PaaS as delivery models for data. Examples include iPaaS (Integration Platform as

880-786: A collaboration with Cisco Systems. One result was the Cisco Nexus 1000V , a distributed virtual software switch, an integrated option in the VMware infrastructure. In April 2011, EMC transferred control of the Mozy backup service to VMware. On April 12, 2011, VMware released an open-source platform-as-a-service system called Cloud Foundry , as well as a hosted version of the service. This supported application deployment for Java , Ruby on Rails , Sinatra , Node.js , and Scala , as well as database support for MySQL , MongoDB , Redis , PostgreSQL , and RabbitMQ . In August 2012, Pat Gelsinger

968-410: A completely virtualized set of hardware to the guest operating system. VMware software virtualizes the hardware for a video adapter, a network adapter, and hard disk adapters. The host provides pass-through drivers for guest USB, serial, and parallel devices. In this way, VMware virtual machines become highly portable between computers, because every host looks nearly identical to the guest. In practice,

1056-469: A considerable amount of computing power and memory and are traditionally executed on clusters of computers. In 2016 a handful of companies, including R-HPC, Amazon Web Services , Univa , Silicon Graphics International , Sabalcore, Gomput, and Penguin Computing offered a high-performance computing cloud. The Penguin On Demand (POD) cloud was one of the first non-virtualized remote HPC services offered on

1144-405: A development environment to application developers. The provider typically develops toolkit and standards for development and channels for distribution and payment. In the PaaS models, cloud providers deliver a computing platform , typically including an operating system, programming-language execution environment, database, and the web server. Application developers develop and run their software on

1232-591: A distributed set of machines in different locations, connected to a single network or hub service. It is possible to distinguish between two types of distributed clouds: public-resource computing and volunteer cloud. Multicloud is the use of multiple cloud computing services in a single heterogeneous architecture to reduce reliance on single vendors, increase flexibility through choice, mitigate against disasters, etc. It differs from hybrid cloud in that it refers to multiple cloud services, rather than multiple deployment modes (public, private, legacy). Poly cloud refers to

1320-560: A form of virtualized computing." according to ISO . Function as a service is a form of serverless computing. The deployment of services to the cloud is referred to as cloud migration. Reverse cloud migration, also known as cloud repatriation, refers to moving cloud-based workloads back to on-premises infrastructures including enterprise data centers, colocation providers, and managed service providers. Cloud repatriation occurs due to security concerns, costs, performance issues, compatibility problems, and uptime concerns. Private cloud

1408-717: A report by Gartner , a survey of 200 IT leaders revealed that 69% experienced budget overruns in their organizations' cloud expenditures during 2023. Conversely, 31% of IT leaders whose organizations stayed within budget attributed their success to accurate forecasting and budgeting, proactive monitoring of spending, and effective optimization. Typically, cloud providers' Service Level Agreements (SLAs) do not encompass all forms of service interruptions. Exclusions typically include planned maintenance, downtime resulting from external factors such as network issues, human errors , like misconfigurations, natural disasters , force majeure events, or security breaches . Typically, customers bear

1496-511: A significant physical footprint, requiring allocations of space, hardware, and environmental controls. These assets have to be refreshed periodically, resulting in additional capital expenditures. They have attracted criticism because users "still have to buy, build, and manage them" and thus do not benefit from less hands-on management, essentially "[lacking] the economic model that makes cloud computing such an intriguing concept". Cloud services are considered "public" when they are delivered over

1584-542: A single attack—a process he called "hyperjacking". Some examples of this include the Dropbox security breach, and iCloud 2014 leak. Dropbox had been breached in October 2014, having over seven million of its users passwords stolen by hackers in an effort to get monetary value from it by Bitcoins (BTC). By having these passwords, they are able to read private data as well as have this data be indexed by search engines (making

1672-421: A specific community with common concerns (security, compliance, jurisdiction, etc.), whether it is managed internally or by a third-party, and hosted internally or externally, the costs are distributed among fewer users compared to a public cloud (but more than a private cloud). As a result, only a portion of the potential cost savings of cloud computing is achieved. A cloud computing platform can be assembled from

1760-469: A system administrator can pause operations on a virtual machine guest, move or copy that guest to another physical computer, and there resume execution exactly at the point of suspension. Alternatively, for enterprise servers, a feature called vMotion allows the migration of operational guest virtual machines between similar but separate hardware hosts sharing the same storage (or, with vMotion Storage, separate storage can be used, too). Each of these transitions

1848-487: A thin client interface, such as a web browser (e.g., web-based email), or a program interface. The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings. In the software as a service (SaaS) model, users gain access to application software and databases . Cloud providers manage

1936-564: A virtual-machine disk-image library, raw block storage , file or object storage , firewalls, load balancers, IP addresses, virtual local area networks (VLANs), and software bundles. IaaS-cloud providers supply resources on-demand from the large pools of equipment installed in data centers . For wide-area connectivity, customers can use either the Internet or carrier clouds (dedicated virtual private networks , VPNs). To deploy their applications, users install operating-system images and

2024-403: Is Linux containers , which run in isolated partitions of a Linux kernel that runs directly on the physical hardware. Containers are isolated, secured and managed using Linux cgroups and namespaces. Containerisation offers higher performance than virtualization because there is no hypervisor overhead. The global IaaS market is projected to reach a value of $ 411.9 billion by 2030, expanding at

2112-539: Is a need for understanding complex technologies and their interconnections to have power and agency within them. The metaphor of the cloud can be seen as problematic as cloud computing retains the aura of something noumenal and numinous ; it is something experienced without precisely understanding what it is or how it works. Additionally, cloud migration is a significant challenge. This process involves transferring data, applications, or workloads from one cloud environment to another, or from on-premises infrastructure to

2200-467: Is a paradigm for enabling network access to a scalable and elastic pool of shareable physical or virtual resources with self-service provisioning and administration on-demand." according to ISO . In 2011, the National Institute of Standards and Technology (NIST) identified five "essential characteristics" for cloud systems. Below are the exact definitions according to NIST: By 2023,

2288-539: Is a relatively recent model in cloud computing, with most BaaS startups dating from 2011 or later but trends indicate that these services are gaining significant mainstream traction with enterprise consumers. "Serverless computing is a cloud service category in which the customer can use different cloud capabilities types without the customer having to provision, deploy and manage either hardware or software resources, other than providing customer application code or providing customer data. Serverless computing represents

2376-552: Is cloud infrastructure operated solely for a single organization, whether managed internally or by a third party, and hosted either internally or externally. Undertaking a private cloud project requires significant engagement to virtualize the business environment, and requires the organization to reevaluate decisions about existing resources. It can improve business, but every step in the project raises security issues that must be addressed to prevent serious vulnerabilities. Self-run data centers are generally capital intensive. They have

2464-429: Is completely transparent to any users on the virtual machine at the time it is being migrated. VMware's products predate the virtualization extensions to the x86 instruction set, and do not require virtualization-enabled processors. On newer processors, the hypervisor is now designed to take advantage of the extensions. However, unlike many other hypervisors, VMware still supports older processors. In such cases, it uses

2552-427: Is in the cloud at any time. It could accidentally or deliberately alter or delete information. Many cloud providers can share information with third parties if necessary for purposes of law and order without a warrant. That is permitted in their privacy policies, which users must agree to before they start using cloud services. Solutions to privacy include policy and legislation as well as end-users' choices for how data

2640-489: Is more secure for them to use a public cloud. There is the risk that end users do not understand the issues involved when signing on to a cloud service (persons sometimes do not read the many pages of the terms of service agreement, and just click "Accept" without reading). This is important now that cloud computing is common and required for some services to work, for example for an intelligent personal assistant (Apple's Siri or Google Assistant ). Fundamentally, private cloud

2728-496: Is no hypervisor overhead. IaaS clouds often offer additional resources such as a virtual-machine disk-image library, raw block storage , file or object storage , firewalls, load balancers , IP addresses , virtual local area networks (VLANs), and software bundles. The NIST 's definition of cloud computing describes IaaS as "where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control

2816-537: Is not a derivative of the Linux kernel, denying Hellwig's core claim. VMware said it offered a way to use Linux device drivers with ESXi, and that code does use some Linux GPLv2-licensed code and so it had published the source, meeting GPLv2 requirements. The lawsuit was dismissed by the court in July 2016 and Hellwig announced he would file an appeal. The appeal was decided February 2019 and again dismissed by German court, on

2904-454: Is reduced visibility and control. Cloud users may not have full insight into how their cloud resources are managed, configured, or optimized by their providers. They may also have limited ability to customize or modify their cloud services according to their specific needs or preferences. Complete understanding of all technology may be impossible, especially given the scale, complexity, and deliberate opacity of contemporary systems; however, there

2992-479: Is seen as more secure with higher levels of control for the owner, however public cloud is seen to be more flexible and requires less time and money investment from the user. The attacks that can be made on cloud computing systems include man-in-the middle attacks, phishing attacks, authentication attacks, and malware attacks. One of the largest threats is considered to be malware attacks, such as Trojan horses . Recent research conducted in 2022 has revealed that

3080-487: Is stored. Users can encrypt data that is processed or stored within the cloud to prevent unauthorized access. Identity management systems can also provide practical solutions to privacy concerns in cloud computing. These systems distinguish between authorized and unauthorized users and determine the amount of data that is accessible to each entity. The systems work by creating and describing identities, recording activities, and getting rid of unused identities. According to

3168-468: Is transparent to the cloud user, who sees only a single access-point. To accommodate a large number of cloud users, cloud applications can be multitenant , meaning that any machine may serve more than one cloud-user organization. The pricing model for SaaS applications is typically a monthly or yearly flat fee per user, so prices become scalable and adjustable if users are added or removed at any point. It may also be free. Proponents claim that SaaS gives

3256-990: The IBM SmartCloud framework in 2011, and Oracle announced the Oracle Cloud in 2012. In December 2019, Amazon launched AWS Outposts, a service that extends AWS infrastructure, services, APIs , and tools to customer data centers, co-location spaces, or on-premises facilities. Advocates of public and hybrid clouds claim that cloud computing allows companies to avoid or minimize up-front IT infrastructure costs. Proponents also claim that cloud computing allows enterprises to get their applications up and running faster, with improved manageability and less maintenance, and that it enables IT teams to more rapidly adjust resources to meet fluctuating and unpredictable demand, providing burst computing capability: high computing power at certain periods of peak demand. Additional value propositions of cloud computing include: One of

3344-610: The International Organization for Standardization (ISO) had expanded and refined the list. The history of cloud computing extends back to the 1960s, with the initial concepts of time-sharing becoming popularized via remote job entry (RJE). The "data center" model, where users submitted jobs to operators to run on mainframes, was predominantly used during this era. This was a time of exploration and experimentation with ways to make large-scale computing power available to more users through time-sharing , optimizing

3432-568: The Lazarus Group cybercrime group, which is possibly linked to North Korea , was actively using Log4Shell "to inject backdoors that fetch information-stealing payloads on VMware Horizon servers", including VMware Horizon . On May 26, 2022, Broadcom announced its intention to acquire VMware for approximately $ 61 billion in cash and stock in addition to assuming $ 8 billion of VMware's net debt, and that Broadcom Software Group would rebrand and operate as VMware. In November 2022,

3520-632: The Software Freedom Conservancy announced it was funding litigation by Christoph Hellwig in Hamburg, Germany against VMware for alleged violation of his copyrights in its ESXi product. Hellwig's core claim is that ESXi is a derivative work of the GPLv2-licensed Linux kernel 2.4, and therefore VMware is not in compliance with GPLv2 because it does not publish the source code to ESXi. VMware publicly stated that ESXi

3608-439: The board of directors fired VMware co-founder, president and CEO Diane Greene, who was replaced by Paul Maritz , a 14-year Microsoft veteran who was heading EMC's cloud computing business unit. Greene had been CEO since the company's founding, ten years earlier. On September 10, 2008, Mendel Rosenblum, the company's co-founder, chief scientist, and the husband of Diane Greene, resigned. On September 16, 2008, VMware announced

Services include user management, push notifications , integration with social networking services and more. This

3784-683: The Broadcom acquisition. In February 2024 private equity firm KKR and Broadcom agreed for KKR to acquire Broadcom's End-User Computing (EUC) Division, formerly a division of VMware, for about $ 4 billion. This includes the VDI product Horizon and the device management suite Workspace ONE, formerly AirWatch . On May 14, 2024, it was announced that VMware Workstation Pro and VMware Fusion Pro would be made free for personal use, with commercial use still requiring payment. In November 2024, VMware announced that commercial use would be free too. In March 2015,

3872-599: The CPU to run code directly whenever possible (as, for example, when running user-mode and virtual 8086 mode code on x86). When direct execution cannot operate, such as with kernel-level and real-mode code, VMware products use binary translation (BT) to re-write the code dynamically. The translated code gets stored in spare memory, typically at the end of the address space , which segmentation mechanisms can protect and make invisible. For these reasons, VMware operates dramatically faster than emulators, running at more than 80% of

3960-512: The Cloud Security Alliance, the top three threats in the cloud are Insecure Interfaces and APIs , Data Loss & Leakage , and Hardware Failure —which accounted for 29%, 25% and 10% of all cloud security outages respectively. Together, these form shared technology vulnerabilities. In a cloud provider platform being shared by different users, there may be a possibility that information belonging to different customers resides on

4048-491: The Trojan horse injection method is a serious problem with harmful impacts on cloud computing systems. The National Institute of Standards and Technology recognized three cloud service models in 2011: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). The International Organization for Standardization (ISO) later identified additional models in 2023, including "Network as

4136-655: The UK's Competition and Markets Authority regulator announced it would investigate whether the acquisition would "result in a substantial lessening of competition within any market or markets in the United Kingdom for goods or services". The transaction closed on November 22, 2023, after a prolonged delay in getting approval from the Chinese regulator on an additional condition that VMware's server software should maintain compatibility with third-party hardware and not require

4224-426: The application runs. This eliminates the need to install and run the application on the cloud user's own computers, which simplifies maintenance and support. Cloud applications differ from other applications in their scalability—which can be achieved by cloning tasks onto multiple virtual machines at run-time to meet changing work demand. Load balancers distribute the work over the set of virtual machines. This process

4312-410: The application software on the cloud infrastructure. Users patch and maintain the operating systems. IaaS services are typically billed as a utility: cost reflects the amount of resources allocated or consumed. Typically, IaaS involves the use of a cloud orchestration technology such as OpenStack , Apache CloudStack , or OpenNebula . It manages the creation of a virtual machine (VM) and decides on

4400-615: The basis of not meeting "procedural requirements for the burden of proof of the plaintiff." In May 2023, VMware was ordered to pay $ 84.5 million for patent infringement on two patents belonging to Densify , a Canadian software company. VMware's most notable products are its hypervisors . VMware became well known for its first type 2 hypervisor known as VMware Workstation . This product has since evolved into two additional hypervisor product lines: VMware's type 1 hypervisors running directly on hardware ( ESX/ESXi ) and their discontinued hosted type 2 hypervisors ( GSX ). VMware software provides

4488-546: The benefits of multiple deployment models. Hybrid cloud can also mean the ability to connect collocation, managed and/or dedicated services with cloud resources. Gartner defines a hybrid cloud service as a cloud computing service that is composed of some combination of private, public and community cloud services, from different service providers. A hybrid cloud service crosses isolation and provider boundaries so that it cannot be simply put in one category of private, public, or community cloud service. It allows one to extend either

4576-483: The capabilities of the enterprise to deliver a specific business service through the addition of externally available public cloud services. Hybrid cloud adoption depends on a number of factors such as data security and compliance requirements, level of control needed over data, and the applications an organization uses. Another example of hybrid cloud is one where IT organizations use public cloud computing resources to meet temporary capacity needs that can not be met by

4664-441: The capacity or the capability of a cloud service, by aggregation, integration or customization with another cloud service. Varied use cases for hybrid cloud composition exist. For example, an organization may store sensitive client data in house on a private cloud application, but interconnect that application to a business intelligence application provided on a public cloud as a software service. This example of hybrid cloud extends

4752-440: The cloud infrastructure consumer-created or acquired applications created using programming languages, libraries, services, and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, or storage, but has control over the deployed applications and possibly configuration settings for the application-hosting environment. PaaS vendors offer

4840-407: The cloud infrastructure. In this model, the cloud user patches and maintains the operating systems and the application software. Cloud providers typically bill IaaS services on a utility computing basis: cost reflects the number of resources allocated and consumed. The NIST 's definition of cloud computing defines Platform as a Service as: The capability provided to the consumer is to deploy onto

4928-495: The cloud operational system can support large numbers of virtual machines and the ability to scale services up and down according to customers' varying requirements. Linux containers run in isolated partitions of a single Linux kernel running directly on the physical hardware. Linux cgroups and namespaces are the underlying Linux kernel technologies used to isolate, secure and manage the containers. The use of containers offers higher performance than virtualization because there

5016-452: The cloud provider, the company typically does not offer monetary compensation. Instead, eligible users may receive credits as outlined in the corresponding SLA. Cloud computing abstractions aim to simplify resource management, but leaky abstractions can expose underlying complexities. These variations in abstraction quality depend on the cloud vendor, service and architecture . Mitigating leaky abstractions requires users to understand

5104-502: The cloud. Cloud migration can be complicated, time-consuming, and expensive, particularly when there are compatibility issues between different cloud platforms or architectures. If not carefully planned and executed, cloud migration can lead to downtime, reduced performance, or even data loss. Applications hosted in the cloud are susceptible to the fallacies of distributed computing , a series of misconceptions that can lead to significant issues in software development and deployment. In

5192-643: The company had partnered with Formula One motor racing team, McLaren Racing . Beginning in January 2022, hackers infiltrated servers using the Log4Shell vulnerability at organizations who failed to implement available patches released by VMware according to PCMag . ZDNET reported in March 2022 that hackers utilized Log4Shell on some customers' VMware servers to install backdoors and for cryptocurrency mining . In May 2022, Bleeping Computer reported that

5280-407: The consumer is able to deploy & run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, & deployed applications; and possibly limited control of select networking components (e.g., host firewalls). IaaS clouds often offer additional resources such as

5368-480: The cultures at Dell and EMC, and at EMC and VMware, are different, and said that they had heard that impending corporate cultural collisions and potentially radical product overlap pruning, would cause many EMC and VMware personnel to leave; VMware CEO Pat Gelsinger , following rumors, categorically denied that he would leave. In August 2016 VMware introduced the VMware Cloud Provider website. Mozy

The NIST 's definition of cloud computing defines Software as a Service as: The capability provided to the consumer is to use the provider's applications running on a cloud infrastructure . The applications are accessible from various client devices through either

5544-440: The data is in the cloud initially hampered adoption of cloud for big data , but now that much data originates in the cloud and with the advent of bare-metal servers , the cloud has become a solution for use cases including business analytics and geospatial analysis . HPC cloud refers to the use of cloud computing services and infrastructure to execute high-performance computing (HPC) applications. These applications consume

5632-658: The establishment of Amazon Web Services (AWS) in 2002, which allowed developers to build applications independently. In 2006 Amazon Simple Storage Service, known as Amazon S3 , and the Amazon Elastic Compute Cloud (EC2) were released. In 2008 NASA 's development of the first open-source software for deploying private and hybrid clouds. The following decade saw the launch of various cloud services. In 2010, Microsoft launched Microsoft Azure , and Rackspace Hosting and NASA initiated an open-source cloud-software project, OpenStack . IBM introduced

5720-667: The first year, with roughly 20 employees by the end of 1998. The company was launched officially early in the second year, in February 1999, at the DEMO conference organized by Chris Shipley . The first product, VMware Workstation , was delivered in May 1999, and the company entered the server market in 2001 with VMware GSX Server (hosted) and VMware ESX Server (host-less). In 2003, VMware launched VMware Virtual Center, vMotion, and Virtual Symmetric Multi-Processing (SMP) technology. 64-bit support

5808-430: The functionality of the solutions, cost , integrational and organizational aspects as well as safety & security are influencing the decision of enterprises and organizations to choose a public cloud or on-premises solution. Hybrid cloud is a composition of a public cloud and a private environment, such as a private cloud or on-premises resources, that remain distinct entities but are bound together, offering

5896-446: The general availability of vCloud Hybrid Service and expansion to Sterling, Virginia , Santa Clara, California , Dallas, Texas , and a service beta in the UK. It announced the acquisition of Desktone in October 2013. In January 2016, in anticipation of Dell 's acquisition of EMC, VMware announced a restructuring to reduce about 800 positions, and some executives resigned. The entire development team behind VMware Workstation and Fusion

5984-572: The hypervisor (i.e. physical host) in order to start it. A hypervisor runs virtual machines (VMs) as guests. Pools of hypervisors in the cloud operational system can support large numbers of virtual machines and the ability to scale services up and down according to demand by customers. Hypevisors include Xen , Oracle VirtualBox , Oracle VM , KVM , VMware ESX /ESXi, or Microsoft Hyper-V . It also enables VM migration between hosts, allocates storage volumes, and attaches them to VMs that track usage information for billing. An alternative to hypervisors

6072-410: The implementation details and limitations of the cloud services they utilize. Service lock-in within the same vendor occurs when a customer becomes dependent on specific services within a cloud vendor, making it challenging to switch to alternative services within the same vendor when their needs change. Cloud computing poses privacy concerns because the service provider can access the data that

6160-679: The information public). There is the problem of legal ownership of the data (If a user stores some data in the cloud, can the cloud provider profit from it?). Many Terms of Service agreements are silent on the question of ownership. Physical control of the computer equipment (private cloud) is more secure than having the equipment off-site and under someone else's control (public cloud). This delivers great incentive to public cloud computing service providers to prioritize building and maintaining strong management of secure services. Some small businesses that do not have expertise in IT security could find that it

6248-454: The infrastructure and platforms that run the applications. SaaS is sometimes referred to as "on-demand software" and is usually priced on a pay-per-use basis or using a subscription fee. In the SaaS model, cloud providers install and operate application software in the cloud and cloud users access the software from cloud clients. Cloud users do not manage the cloud infrastructure and platform where

6336-592: The infrastructure, platform, and applications, and increasing efficiency for end users. The "cloud" metaphor for virtualized services dates to 1994, when it was used by General Magic for the universe of "places" that mobile agents in the Telescript environment could "go". The metaphor is credited to David Hoffman, a General Magic communications specialist, based on its long-standing use in networking and telecom. The expression cloud computing became more widely known in 1996 when Compaq Computer Corporation drew up

6424-480: The main challenges of cloud computing, in comparison to more traditional on-premises computing, is data security and privacy. Cloud users entrust their sensitive data to third-party providers, who may not have adequate measures to protect it from unauthorized access, breaches, or leaks. Cloud users also face compliance risks if they have to adhere to certain regulations or standards regarding data protection, such as GDPR or HIPAA . Another challenge of cloud computing

6512-733: The private cloud. This capability enables hybrid clouds to employ cloud bursting for scaling across clouds. Cloud bursting is an application deployment model in which an application runs in a private cloud or data center and "bursts" to a public cloud when the demand for computing capacity increases. A primary advantage of cloud bursting and a hybrid cloud model is that an organization pays for extra compute resources only when they are needed. Cloud bursting enables data centers to create an in-house IT infrastructure that supports average workloads, and use cloud resources from public or private clouds, during spikes in processing demands. Community cloud shares infrastructure between several organizations from

6600-501: The public Internet, and they may be offered as a paid subscription, or free of charge. Architecturally, there are few differences between public- and private-cloud services, but security concerns increase substantially when services (applications, storage, and other resources) are shared by multiple customers. Most public-cloud providers offer direct-connection services that allow customers to securely link their legacy data centers to their cloud-resident applications. Several factors like

6688-509: The responsibility of monitoring SLA compliance and must file claims for any unmet SLAs within a designated timeframe. Customers should be aware of how deviations from SLAs are calculated, as these parameters may vary by service. These requirements can place a considerable burden on customers. Additionally, SLA percentages and conditions can differ across various services within the same provider, with some services lacking any SLA altogether. In cases of service interruptions due to hardware failures in

6776-490: The same data server. Additionally, Eugene Schultz , chief technology officer at Emagined Security, said that hackers are spending substantial time and effort looking for ways to penetrate the cloud. "There are some real Achilles' heels in the cloud infrastructure that are making big holes for the bad guys to get into". Because data from hundreds or thousands of companies can be stored on large cloud servers, hackers can theoretically gain control of huge stores of information through

6864-545: The speed that the virtual guest operating system would run directly on the same hardware. In one study VMware claims a slowdown over native ranging from 0–6 percent for the VMware ESX Server. VMware's storage and availability products are composed of two primary offerings: !(predecessor products) 37°24′08″N 122°08′41″W  /  37.4021124°N 122.1445973°W  / 37.4021124; -122.1445973 Cloud computing "Cloud computing

6952-555: The underlying cloud infrastructure but has control over operating systems, storage, and deployed applications; and possibly limited control of select networking components (e.g., host firewalls)." IaaS-cloud providers supply these resources on-demand from their large pools of equipment installed in data centers . For wide-area connectivity, customers can use either the Internet or carrier clouds (dedicated virtual private networks ). To deploy their applications, cloud users install operating-system images and their application software on

7040-664: The use of Broadcom's hardware products. On completion, Broadcom reorganized the company into four divisions: VMware Cloud Foundation, Tanzu, Software-Defined Edge, and Application Networking and Security, and subsequently laid off over 2,800 employees. Broadcom also relocated its headquarters from North San Jose to VMware's headquarters campus in Palo Alto. On December 13, 2023, VMware ended availability for perpetually licensed products such as vSphere and Cloud Foundation, moving exclusively to subscription-based offerings. The company stated that this had been planned as an eventuality prior to

7128-414: The use of multiple public clouds for the purpose of leveraging specific services that each provider offers. It differs from Multi cloud in that it is not designed to increase flexibility or mitigate against failures but is rather used to allow an organization to achieve more than could be done with a single provider. The issues of transferring large amounts of data to the cloud as well as data security once

7216-445: The users' data on the cloud provider's server. As a result, there could be unauthorized access to the data. Examples of applications offered as SaaS are games and productivity software like Google Docs and Office Online. SaaS applications may be integrated with cloud storage or File hosting services , which is the case with Google Docs being integrated with Google Drive , and Office Online being integrated with OneDrive . In
