DevOps is a set of practices that combines software development (Dev) and IT operations (Ops). It aims to shorten the systems development life cycle and provide continuous delivery with high software quality.[1][2] DevOps is complementary with Agile software development; several DevOps aspects came from Agile methodology.
With modern businesses moving at the speed of cloud, DevOps has become an increasingly common approach to software delivery that development and operations teams use to build, test, deploy, and monitor applications with speed, quality, and control.
DevOps is essential for any business aspiring to be lean, agile, and capable of responding rapidly to changing marketplace demands. It is an approach on the journey to lean and agile software delivery that promotes closer collaboration between lines of business, development, and IT operations while removing barriers between your stakeholders, and your customers.

Along with its efforts to break down barriers to communication and collaboration between development and IT operations teams, a core value of DevOps is customer satisfaction and the faster delivery of value. DevOps is also designed to propel business innovation and the drive for continuous process improvement.
The practice of DevOps encourages faster, better, more secure delivery of business value to an organization’s end customers. This value might take the form of more frequent product releases, features, or updates. It can involve how quickly a product release or new feature gets into customers’ hands—all with the proper levels of quality and security. Or, it might focus on how quickly an issue or bug is identified, and then resolved and re-released.
Underlying infrastructure also supports DevOps with seamless performance, availability, and reliability of software as it is first developed and tested then released into production.
DevOps is an approach to culture, automation, and platform design intended to deliver increased business value and responsiveness through rapid, high-quality service delivery. This is all made possible through fast-paced, iterative IT service delivery. DevOps means linking legacy apps with newer cloud-native apps and infrastructure.
A DevOps toolchain is a set or combination of tools that aid in the delivery, development, and management of software applications throughout the systems development life cycle, 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, Package, Release, Configure, Monitor, and Version Control.
In DevOps, key principles are continuous integration and continuous delivery. The DevOps toolchain assists businesses in achieving the promise of DevOps by maintaining a healthy software development pipeline. Toolchains help team members complete and simplify more complex tasks of the development process.
If DevOps is the new industry standard, implementing a DevOps toolchain is the next iteration of it. Toolchains can be created, orchestrated and stored in the cloud using some key aspects of a DevOps approach:
Automation
Integration
Self-service
Collaboration
DevOps Tools help automate the process. It emphasizes communication, collaboration between product management, software development, and operations professionals.
