DevOps toolchain

A DevOps toolchain is a set or combination of tools that aid in the delivery, development, and management of applications throughout the software development lifecycle, as coordinated by an organisation that uses DevOps practices.

Generally, DevOps tools fit into one or more activities, which supports specific DevOps initiatives: Plan, Create, Verify, Preprod, Release, Configure, and Monitor.

Another proposed toolchain model was referenced in 2014 as coming from "an unknown source" as Plan, Code, Build, Test, Release, Deploy, Operate and Monitor.

In software, a toolchain is the set of programming tools that is used to perform a complex software development task or to create a software product, which is typically another computer program or a set of related programs. In general, the tools forming a toolchain are executed consecutively so the output or resulting environment state of each tool becomes the input or starting environment for the next one, but the term is also used when referring to a set of related tools that are not necessarily executed consecutively.

As DevOps is a set of practices that emphasizes the collaboration and communication of both software developers and other information technology (IT) professionals, while automating the process of software delivery and infrastructure changes, its implementation can include the definition of the series of tools used at various stages of the lifecycle; because DevOps is a cultural shift and collaboration between development and operations, there is no one product that can be considered a single DevOps tool. Instead a collection of tools, potentially from a variety of vendors, are used in one or more stages of the lifecycle.

Plan is composed of two things: "define" and "plan". This activity refers to the business value and application requirements. Specifically "Plan" activities include:

A combination of the IT personnel will be involved in these activities: business application owners, software development, software architects, continual release management, security officers and the organization responsible for managing the production of IT infrastructure. Some notable vendors and solutions that facilitate Plan include: Atlassian, CA Technologies, iRise and Jama Software.
