77-413: DevOps is a methodology in the software development and IT industry. Used as a set of practices and tools, DevOps integrates and automates the work of software development ( Dev ) and IT operations ( Ops ) as a means for improving and shortening the systems development life cycle . DevOps is complementary to agile software development ; several DevOps aspects came from the agile approach. Automation
154-511: A scrum master . Scrum's approach to product development involves bringing decision-making authority to an operational level. Unlike a sequential approach to product development, scrum is an iterative and incremental framework for product development. Scrum allows for continuous feedback and flexibility, requiring teams to self-organize by encouraging physical co-location or close online collaboration, and mandating frequent communication among all team members. The flexible approach of scrum
231-423: A central place using a simple code." Many organizations use version control to power DevOps automation technologies like virtual machines , containerization (or OS-level virtualization ), and CI/CD . The paper "DevOps: development of a toolchain in the banking domain" notes that with teams of developers working on the same project, "All developers need to make changes to the same codebase and sometimes edit even
308-412: A deadline. Software analysis begins with a requirements analysis to capture the business needs of the software. Challenges for the identification of needs are that current or potential users may have different and incompatible needs, may not understand their own needs, and change their needs during the process of software development. Ultimately, the result of analysis is a detailed specification for
385-404: A developer or scrum master. As a tool for coordination, scrum of scrums allows teams to collectively work on team-wide risks, impediments, dependencies, and assumptions (RIDAs), which may be tracked in a backlog of their own. Large-scale scrum is a product development framework that scales scrum with varied rules and guidelines, developed by Bas Vodde and Craig Larman . There are two levels to
462-654: A sprint if necessary, without the input of team members. In scrum, the term developer or team member refers to anyone who plays a role in the development and support of the product and can include researchers, architects , designers, programmers, etc. Scrum is facilitated by a scrum master, whose role is to educate and coach teams about scrum theory and practice. Scrum masters have differing roles and responsibilities from traditional team leads or project managers . Some scrum master responsibilities include coaching, objective setting, problem solving, oversight, planning, backlog management, and communication facilitation. On
539-515: A tailored approach. Mobile DevOps is not simply as a branch of DevOps specific to mobile app development, instead an extension and reinterpretation of the DevOps philosophy due to very specific requirements of the mobile world. In 2003, Google developed site reliability engineering (SRE), an approach for releasing new features continuously into large-scale high-availability systems while maintaining high-quality end-user experience. While SRE predates
616-502: A team delivers. They do not dictate the technical solutions of a team but may instead attempt to seek consensus among team members. As the primary liaison of the scrum team towards stakeholders, product owners are responsible for communicating announcements, project definitions and progress, RIDAs ( risks , impediments, dependencies , and assumptions), funding and scheduling changes, the product backlog, and project governance, among other responsibilities. Product owners can also cancel
693-400: Is white-box testing with special focus on security. Depending on the programming language, different tools are needed to do such static code analysis. The software composition is analyzed, especially libraries, and the version of each component is checked against vulnerability lists published by CERT and other expert groups. When giving software to clients, library licenses and their match to
770-504: Is a core principle for achieving DevOps success and CI/CD is a critical component. Plus, improved collaboration and communication between and within teams helps achieve faster time to market , with reduced risks. Mobile DevOps is a set of practices that applies the principles of DevOps specifically to the development of mobile applications. Traditional DevOps focuses on streamlining the software development process in general, but mobile development has its own unique challenges that require
847-511: Is a framework that provides the viewpoints on the system and its environment , to be used in the software development process . It is a graphical representation of the underlying semantics of a view. The purpose of viewpoints and views is to enable human engineers to comprehend very complex systems and to organize the elements of the problem around domains of expertise . In the engineering of physically intensive systems, viewpoints often correspond to capabilities and responsibilities within
SECTION 10
#1732802286973924-408: Is a popular way of managing changes made to the software. Whenever a new version is checked in, the software saves a backup of all modified files. If multiple programmers are working on the software simultaneously, it manages the merging of their code changes. The software highlights cases where there is a conflict between two sets of changes and allows programmers to fix the conflict. A view model
1001-466: Is a software production model based on scrum and kanban . To illustrate each stage of work, teams working in the same space often use post-it notes or a large whiteboard. Kanban models allow a team to visualize work stages and limitations. Scrum of scrums is a technique to operate scrum at scale for multiple teams coordinating on the same product. Scrum-of-scrums daily scrum meetings involve ambassadors selected from each individual team, who may be either
1078-544: Is an augmentation of DevOps to allow for security practices to be integrated into the DevOps approach. Contrary to a traditional centralized security team model, each delivery team is empowered to factor in the correct security controls into their software delivery. Security practices and testing are performed earlier in the development lifecycle, hence the term " shift left ". Security is tested in three main areas: static, software composition, and dynamic. Checking software statically via static application security testing (SAST)
1155-590: Is an important part of DevOps. Software programmers and architects should use " fitness functions " to keep their software in check. Other than it being a cross-functional combination (and a portmanteau ) of the terms and concepts for "development" and "operations", academics and practitioners have not developed a universal definition for the term "DevOps". Most often, DevOps is characterized by key principles: shared ownership, workflow automation, and rapid feedback. From an academic perspective, Len Bass , Ingo Weber, and Liming Zhu—three computer science researchers from
1232-433: Is based in part on the notion of requirement volatility, that stakeholders will change their requirements as the project evolves. The use of the term scrum in software development came from a 1986 Harvard Business Review paper titled "The New New Product Development Game" by Hirotaka Takeuchi and Ikujiro Nonaka . Based on case studies from manufacturing firms in the automotive, photocopier, and printer industries ,
1309-449: Is correctly incorporated with the newer software. Design involves choices about the implementation of the software, such as which programming languages and database software to use, or how the hardware and network communications will be organized. Design may be iterative with users consulted about their needs in a process of trial and error . Design often involves people expert in aspect such as database design , screen architecture, and
1386-833: Is essential to success. This is more easily achieved if the team is small, used to working together, and located near each other. Communications also help identify problems at an earlier state of development and avoid duplicated effort. Many development projects avoid the risk of losing essential knowledge held by only one employee by ensuring that multiple workers are familiar with each component. Software development involves professionals from various fields, not just software programmers but also individuals specialized in testing, documentation writing, graphic design , user support, marketing , and fundraising. Although workers for proprietary software are paid, most contributors to open-source software are volunteers. Alternately, they may be paid by companies whose business model does not involve selling
1463-533: Is frequently tailored or adapted in different contexts to achieve varying aims. A common approach to adapting scrum is the combination of scrum with other software development methodologies, as scrum does not cover the whole product development lifecycle . Various scrum practitioners have also suggested more detailed techniques for how to apply or adapt scrum to particular problems or organizations. Many refer to these techniques as 'patterns', an analogous use to design patterns in architecture and software. Scrumban
1540-399: Is helpful for new developers to understand the project when they begin working on it. In agile development, the documentation is often written at the same time as the code. User documentation is more frequently written by technical writers . Accurate estimation is crucial at the feasibility stage and in delivering the product on time and within budget. The process of generating estimations
1617-422: Is inefficient, difficult to understand, or lacking documentation on its functionality. These standards are especially likely to break down in the presence of deadlines. As a result, testing, debugging, and revising the code becomes much more difficult. Code refactoring , for example adding more comments to the code, is a solution to improve the understandability of code. Testing is the process of ensuring that
SECTION 20
#17328022869731694-411: Is no longer than one month and commonly lasts two weeks. The scrum team assesses progress in time-boxed, stand-up meetings of up to 15 minutes, called daily scrums . At the end of the sprint, the team holds two further meetings: one sprint review to demonstrate the work for stakeholders and solicit feedback, and one internal sprint retrospective . A person in charge of a scrum team is typically called
1771-440: Is often delegated by the project manager . Because the effort estimation is directly related to the size of the complete application, it is strongly influenced by addition of features in the requirements—the more requirements, the higher the development cost. Aspects not related to functionality, such as the experience of the software developers and code reusability, are also essential to consider in estimation. As of 2019 , most of
1848-432: Is often used to break down the customer's requirements into pieces that can be implemented by software programmers. The underlying logic of the program may be represented in data-flow diagrams , data dictionaries , pseudocode , state transition diagrams , and/or entity relationship diagrams . If the project incorporates a piece of legacy software that has not been modeled, this software may be modeled to help ensure it
1925-435: Is organized into at least three categories of individuals: the product owner, developers, and the scrum master. The product owner liaises with stakeholders, those who have an interest in the project's outcome, to communicate tasks and expectations with developers. Developers in a scrum team organize work by themselves, with the facilitation of a scrum master. Each scrum team has one product owner. The product owner focuses on
2002-401: Is robust to heavy levels of input or usage), integration testing (to ensure that the software is adequately integrated with other software), and compatibility testing (measuring the software's performance across different operating systems or browsers). When tests are written before the code, this is called test-driven development . Production is the phase in which software is deployed to
2079-850: Is the process of designing and implementing a software solution to satisfy a user . The process is more encompassing than programming , writing code , in that it includes conceiving the goal, evaluating feasibility, analyzing requirements , design , testing and release . The process is part of software engineering which also includes organizational management , project management , configuration management and other aspects. Software development involves many skills and job specializations including programming , testing , documentation , graphic design , user support , marketing , and fundraising . Software development involves many tools including: compiler , integrated development environment (IDE), version control , computer-aided software engineering , and word processor . The details of
2156-438: Is the subset of items from the product backlog intended for developers to address in a particular sprint. Developers fill this backlog with tasks they deem appropriate to fill the sprint, using past performance to assess their capacity for each sprint. The scrum approach has tasks on the sprint backlog not assigned to developers by any particular individual or leader. Team members self organize by pulling work as needed according to
2233-649: The CSIRO and the Software Engineering Institute —suggested defining DevOps as "a set of practices intended to reduce the time between committing a change to a system and the change being placed into normal production, while ensuring high quality". However, the term is used in multiple contexts. At its most successful, DevOps is a combination of specific practices, culture change, and tools. Proposals to combine software development methodologies with deployment and operations concepts began to appear in
2310-424: The open web application security project , e.g. its TOP10, and by other bodies. DevSecOps has also been described as a cultural shift involving a holistic approach to producing secure software by integrating security education, security by design, and security automation. DevOps initiatives can create cultural changes in companies by transforming the way operations , developers , and testers collaborate during
2387-471: The programming language ). Documentation comes in two forms that are usually kept separate—that intended for software developers, and that made available to the end user to help them use the software. Most developer documentation is in the form of code comments for each file, class , and method that cover the application programming interface (API)—how the piece of software can be accessed by another—and often implementation details. This documentation

2464-466: The "top-down" prescriptive approach and rigid framework of ITIL in the 1990s, DevOps is "bottom-up" and flexible, having been created by software engineers for their own needs. The motivations for what has become modern DevOps and several standard DevOps practices such as automated build and test, continuous integration , and continuous delivery originated in the Agile world, which dates (informally) to
2541-401: The 1990s, and formally to 2001. Agile development teams using methods such as extreme programming couldn't "satisfy the customer through early and continuous delivery of valuable software" unless they took responsibility for operations and infrastructure for their applications, automating much of that work. Because Scrum emerged as the dominant Agile framework in the early 2000s and it omitted
2618-642: The Scrum Alliance and set up the Certified Scrum accreditation series. Schwaber left the Scrum Alliance in late 2009 and subsequently founded Scrum.org, which oversees the parallel Professional Scrum accreditation series. Since 2009, a public document called The Scrum Guide has been published and updated by Schwaber and Sutherland. It has been revised six times, with the most recent version having been published in November 2020. A scrum team
2695-401: The architecture of an individual service to emerge through continuous refactoring. It also supports consistency, reliability, and efficiency within the organization, and is usually enabled by a shared code repository or version control. As DevOps researcher Ravi Teja Yarlagadda hypothesizes, "Through DevOps, there is an assumption that all functions can be carried out, controlled, and managed in
2772-416: The authors outlined a new approach to product development for increased speed and flexibility. They called this the rugby approach, as the process involves a single cross-functional team operating across multiple overlapping phases in which the team "tries to go the distance as a unit, passing the ball back and forth". The authors later developed scrum in their book, The Knowledge Creating Company . In
2849-489: The available methodologies are best suited to specific kinds of projects, based on various technical, organizational, project, and team considerations. Another focus in many programming methodologies is the idea of trying to catch issues such as security vulnerabilities and bugs as early as possible ( shift-left testing ) to reduce the cost of tracking and fixing them. In 2009, it was estimated that 32 percent of software projects were delivered on time and budget, and with
2926-429: The backlog priority and their own capabilities and capacity. An increment is a potentially releasable output of a sprint, which meets the sprint goal. It is formed from all the completed sprint backlog items, integrated with the work of all previous sprints. Often used in scrum, a burndown chart is a publicly displayed chart showing remaining work. It provides quick visualizations for reference. The horizontal axis of
3003-446: The backlog. Each sprint ends with two events: The suggested maximum duration of sprint planning is eight hours for a four-week sprint. Each day during a sprint, the developers hold a daily scrum (often conducted standing up ) with specific guidelines, and which may be facilitated by a scrum master. Daily scrum meetings are intended to be less than 15 minutes in length, taking place at the same time and location daily. The purpose of
3080-541: The book More Agile Testing, containing a chapter on testing and DevOps. In 2016, the DORA metrics for throughput (deployment frequency, lead time for changes), and stability (mean time to recover, change failure rate) were published in the State of DevOps report. However, the research methodology and metrics were criticized by experts. In response to these criticisms, the 2023 State of DevOps report published changes that updated
3157-545: The breaking down of large tasks into smaller and clearer ones, the clarification of success criteria, and the revision of changing priorities and returns. Artifacts are a means by which scrum teams manage product development by documenting work done towards the project. The main scrum artifacts used are the product backlog, sprint backlog, and increment. The product backlog is a breakdown of work to be done and contains an ordered list of product requirements (such as features , bug fixes and non-functional requirements ) that

3234-421: The burndown chart shows the days remaining, while the vertical axis shows the amount of work remaining each day. During sprint planning, the ideal burndown chart is plotted. Then, during the sprint, developers update the chart with the remaining work. Updated at the end of each sprint, the release burn-up chart shows progress towards delivering a forecast scope. The horizontal axis of the release burnup chart shows
3311-410: The business side of product development and spends the majority of time liaising with stakeholders and the team. The role is intended to primarily represent the product's stakeholders , the voice of the customer , or the desires of a committee , and bears responsibility for the delivery of business results. Product owners manage the product backlog and are responsible for maximizing the value that
3388-419: The changes to a code are tracked, bookmarked, and making any updates to the history can be made easier. As explained by Red Hat , "visibility to change means the ability to trace and reproduce issues quickly, improving overall security." The following practices can enhance productivity of DevOps pipelines , especially in systems hosted in the cloud : Software development Software development
3465-423: The code executes correctly and without errors. Debugging is performed by each software developer on their own code to confirm that the code does what it is intended to. In particular, it is crucial that the software executes on all inputs, even if the result is incorrect. Code reviews by other developers are often used to scrutinize new code added to the project, and according to some estimates dramatically reduce
3542-419: The development and delivery processes. Getting these groups to work cohesively is a critical challenge in enterprise DevOps adoption. DevOps is as much about culture as it is about the toolchain. Although in principle it is possible to practice DevOps with any architectural style, the microservices architectural style is becoming the standard for building continuously deployed systems. Small size service allows
3619-461: The development of DevOps, they are generally viewed as being related to each other. Some of the original authors of the discipline consider SRE as an implementation of DevOps. Toyota production system, also known under the acronym TPS, was the inspiration for lean thinking with its focus on continuous improvement , kaizen , flow and small batches. The andon cord principle to create fast feedback, swarm and solve problems stems from TPS. DevSecOps
3696-460: The early 1990s, Ken Schwaber used what would become scrum at his company, Advanced Development Methods. Jeff Sutherland , John Scumniotales, and Jeff McKenna developed a similar approach at Easel Corporation, referring to the approach with the term scrum . Sutherland and Schwaber later worked together to integrate their ideas into a single framework, formally known as scrum. Schwaber and Sutherland tested scrum and continually improved it, leading to
3773-432: The end of a sprint, a sprint review is a meeting that has a team share the work they've completed with stakeholders and liaise with them on feedback, expectations, and upcoming plans. At a sprint review completed deliverables are demonstrated to stakeholders. The recommended duration for a sprint review is one hour per week of sprint. A sprint retrospective is a separate meeting that allows team members to internally analyze
3850-408: The end user. During production, the developer may create technical support resources for users or a process for fixing bugs and errors that were not caught earlier. There might also be a return to earlier development phases if user needs changed or were misunderstood. Software development is performed by software developers , usually working on a team. Efficient communications between team members
3927-430: The engineering organization. Fitness functions are automated and objective tests to ensure that the new developments don't deviate from the established constraints, checks and compliance controls. Intellectual property can be an issue when developers integrate open-source code or libraries into a proprietary product, because most open-source licenses used for software require that modifications be released under
SECTION 50
#17328022869734004-627: The engineering practices that were part of many Agile teams, the movement to automate operations and infrastructure functions splintered from Agile and expanded into what has become modern DevOps. Today, DevOps focuses on the deployment of developed software, whether it is developed using Agile oriented methodologies or other methodologies. ArchOps presents an extension for DevOps practice, starting from software architecture artifacts, instead of source code, for operation deployment. ArchOps states that architectural models are first-class entities in software development, deployment, and operations. Automation
4081-789: The framework: the first level, designed for up to eight teams; and the second level, known as 'LeSS Huge', which can accommodate development involving hundreds of developers. A systematic review found "that Distributed Scrum has no impact, positive or negative on overall project success" in distributed software development. Martin Fowler , one of the authors of the Manifesto for Agile Software Development , has criticised what he calls "faux-agile" practices that are "disregarding agile's values and principles", and "the Agile Industrial Complex imposing methods upon people" contrary to
4158-477: The full functionality. An additional 44 percent were delivered, but missing at least one of these features. The remaining 24 percent were cancelled prior to release. Software development life cycle refers to the systematic process of developing applications . The sources of ideas for software products are plentiful. These ideas can come from market research including the demographics of potential new customers, existing customers, sales prospects who rejected
4235-494: The late 80s and early 90s. Around 2007 and 2008, concerns were raised by those within the software development and IT communities that the separation between the two industries, where one wrote and created software entirely separate from those that deploy and support the software was creating a fatal level of dysfunction within the industry. In 2009, the first conference named DevOps Days was held in Ghent , Belgium . The conference
4312-454: The license of the software distributed are in focus, especially copyleft licenses. In dynamic testing, also called black-box testing , software is tested without knowing its inner functions. In DevSecOps this practice may be referred to as dynamic application security testing (DAST) or penetration testing. The goal is early detection of defects including cross-site scripting and SQL injection vulnerabilities. Threat types are published by
4389-481: The meeting is to announce progress made towards the sprint goal and issues that may be hindering the goal, without going into any detailed discussion. Once over, individual members can go into a 'breakout session' or an 'after party' for extended discussion and collaboration. Scrum masters are responsible for ensuring that team members use daily scrums effectively or, if team members are unable to use them, providing alternatives to achieve similar outcomes. Conducted at
4466-412: The most common. The outcome of the sprint is a functional deliverable, or a product which has received some development in increments . When a sprint is abnormally terminated, the next step is to conduct new sprint planning, where the reason for the termination is reviewed. Each sprint starts with a sprint planning event in which a sprint goal is defined. Priorities for planned sprints are chosen out of
4543-407: The number of bugs persisting after testing is complete. Once the code has been submitted, quality assurance —a separate department of non-programmers for most large companies—test the accuracy of the entire software product. Acceptance tests derived from the original software requirements are a popular tool for this. Quality testing also often includes stress and load checking (whether the software
4620-451: The other hand, traditional project managers often have people management responsibilities, which a scrum master does not. Scrum teams do not involve project managers, so as to maximize self-organisation among developers. A sprint (also known as a design sprint , iteration , or timebox ) is a fixed period of time wherein team members work on a specific goal. Each sprint is normally between one week and one month, with two weeks being
4697-403: The performance of servers and other hardware. Designers often attempt to find patterns in the software's functionality to spin off distinct modules that can be reused with object-oriented programming . An example of this is the model–view–controller , an interface between a graphical user interface and the backend . The central feature of software development is creating and understanding
SECTION 60
#17328022869734774-463: The process used for a development effort varies. The process may be confined to a formal, documented standard , or it can be customized and emergent for the development effort. The process may be sequential, in which each major phase (i.e. design, implement and test) is completed before the next begins, but an iterative approach – where small aspects are separately designed, implemented and tested – can reduce risk and cost and increase quality. Each of
4851-433: The product owner gauge the timeline and may influence the ordering of product backlog items. The product owner maintains and prioritizes product backlog items based on considerations such as risk, business value, dependencies, size, and timing. High-priority items at the top of the backlog are broken down into more detail for developers to work on, while tasks further down the backlog may be more vague. The sprint backlog
4928-424: The product that developers can work from. Software analysts often decompose the project into smaller objects, components that can be reused for increased cost-effectiveness, efficiency, and reliability. Decomposing the project may enable a multi-threaded implementation that runs significantly faster on multiprocessor computers. During the analysis and design phases of software development, structured analysis
5005-466: The product, other internal software development staff, or a creative third party. Ideas for software products are usually first evaluated by marketing personnel for economic feasibility, fit with existing channels of distribution, possible effects on existing product lines, required features , and fit with the company's marketing objectives. In the marketing evaluation phase, the cost and time assumptions become evaluated. The feasibility analysis estimates
5082-503: The project's return on investment , its development cost and timeframe. Based on this analysis, the company can make a business decision to invest in further development. After deciding to develop the software, the company is focused on delivering the product at or below the estimated cost and time, and with a high standard of quality (i.e., lack of bugs) and the desired functionality. Nevertheless, most software projects run late and sometimes compromises are made in features or quality to meet
5159-502: The publication of a research paper in 1995, and the Manifesto for Agile Software Development in 2001. Schwaber also collaborated with Babatunde Ogunnaike at DuPont Research Station and the University of Delaware to develop Scrum. Ogunnaike believed that software development projects could often fail when initial conditions change if product management was not rooted in empirical practice. In 2002, Schwaber with others founded
5236-663: The same files. For efficient working, there has to be a system that helps engineers avoid conflicts and retain the codebase history," with the Git version control system and the GitHub platform referenced as examples. GitOps evolved from DevOps. The specific state of deployment configuration is version-controlled . Because the most popular version-control is Git , GitOps' approach has been named after Git . Changes to configuration can be managed using code review practices, and can be rolled back using version-controlling. Essentially, all of
5313-412: The same license. As an alternative, developers may choose a proprietary alternative or write their own software module. Scrum (software development) Scrum is an agile team collaboration framework commonly used in software development and other industries. Scrum prescribes for teams to break work into goals to be completed within time-boxed iterations, called sprints . Each sprint
5390-427: The software that implements the desired functionality. There are various strategies for writing the code. Cohesive software has various components that are independent from each other. Coupling is the interrelation of different software components, which is viewed as undesirable because it increases the difficulty of maintenance . Often, software programmers do not follow industry best practices, resulting in code that
5467-403: The software, but something else—such as services and modifications to open source software. Computer-aided software engineering (CASE) is tools for the partial automation of software development. CASE enables designers to sketch out the logic of a program, whether one to be written, or an already existing one to help integrate it with new code or reverse engineer it (for example, to change
5544-846: The sprints in a release, while the vertical axis shows the amount of work completed at the end of each sprint. Some project managers believe that a team's total capability effort for a single sprint can be derived by evaluating work completed in the last sprint. The collection of historical " velocity " data is a guideline for assisting the team in understanding their capacity. Some have argued that scrum events, such as daily scrums and scrum reviews, hurt productivity and waste time that could be better spent on actual productive tasks. Scrum has also been observed to pose difficulties for part-time or geographically distant teams; those that have highly specialized members who would be better off working by themselves or in working cliques; and those that are unsuitable for incremental and development testing . Scrum
5621-463: The stability metric "mean time to recover" to "failed deployment recovery time" acknowledging the confusion the former metric has caused. Many of the ideas fundamental to DevOps practices are inspired by, or mirror, other well known practices such as Lean and Deming's Plan-Do-Check-Act cycle, through to The Toyota Way and the Agile approach of breaking down components and batch sizes. Contrary to
5698-404: The strengths and weaknesses of the sprint, future areas of improvement, and continuous process improvement actions. Backlog refinement is a process by which team members revise and prioritize a backlog for future sprints. It can be done as a separate stage done before the beginning of a new sprint or as a continuous process that team members work on by themselves. Backlog refinement can include
5775-436: The team maintains for a product . The order of a product backlog corresponds to the urgency of the task. Common formats for backlog items include user stories and use cases . The product backlog may also contain the product owner's assessment of business value and the team's assessment of the product's effort or complexity, which can be stated in story points using the rounded Fibonacci scale . These estimates try to help
5852-520: The tools for estimating the amount of time and resources for software development were designed for conventional applications and are not applicable to web applications or mobile applications . An integrated development environment (IDE) supports software development with enhanced features compared to a simple text editor . IDEs often include automated compiling , syntax highlighting of errors, debugging assistance, integration with version control , and semi-automation of tests. Version control
5929-464: Was founded by Belgian consultant, project manager and agile practitioner Patrick Debois. The conference has now spread to other countries. In 2012, a report called "State of DevOps" was first published by Alanna Brown at Puppet Labs . As of 2014, the annual State of DevOps report was published by Nicole Forsgren , Gene Kim, Jez Humble and others. They stated that the adoption of DevOps was accelerating. Also in 2014, Lisa Crispin and Janet Gregory wrote
