Overview Of DevOps

 

DevOps Definition

DevOps is a combination of development (Dev) and operations (Ops) that unites people, processes, and technology to continually deliver value to customers.

What does DevOps mean for teams? DevOps enables roles - development, IT operations, quality engineering and security - to coordinate and collaborate to produce better and more reliable products. By adopting a DevOps culture and DevOps practices and tools, teams can better meet customer needs, increase trust in the applications they develop, and more quickly reach their business goals.

The Benefits of DevOps

Teams that embrace DevOps culture, practices and tools become highly successful, building better products faster for greater customer satisfaction. This improved collaboration and productivity is also integral to achieving business goals such as:

Accelerating time to market

Adapting to the market and competition

Maintaining system stability and reliability

Improving the mean time to recovery

DevOps and the application lifecycle

DevOps influences the lifecycle of applications throughout its planning, development, delivery and operation phases. Each phase is based on the others and the phases are not role specific. In a true DevOps culture, each role is involved in each phase to a certain extent.

Plan:

During the planning phase, DevOps teams define, define, and describe the features and functionality of the applications and systems they build. They track progress at low and high granularity levels, from single product tasks to tasks that cover multiple product portfolios.

Develop:

The development phase includes all aspects of coding (writing, testing, reviewing, and integrating code by team members), and building that code into build artifacts that can be deployed in a variety of environments. DevOps teams seek to innovate quickly without sacrificing quality, stability and productivity. integration.

Deliver:

Delivery involves deploying applications in production environments in a consistent and reliable manner. The delivery phase also includes the deployment and configuration of the fully governed basic infrastructure that constitutes these environments.

Function:

The operation phase involves the maintenance, monitoring, and troubleshooting of applications in production environments. By adopting DevOps practices, teams work to ensure system reliability, high availability and zero downtime while enhancing security and governance.

DevOps Culture:

DevOps practices automates and optimizes processes through technology, it all starts with the culture of the organization and the people who play a role in it. The challenge of cultivating a DevOps culture requires profound changes in the way people work and collaborate.

Collaboration, visibility and alignment:

Collaboration between teams, which starts with visibility, is one of the hallmarks of a healthy DevOps culture. Different teams such as development and IT operations need to share their DevOps processes, priorities, and concerns. 

Changes in scope and accountability:

As teams align, they become involved and involved in additional life cycle phases, not just those at the heart of their roles. For example, developers become responsible not only for the innovation and quality established during the development phase, but also for the performance and stability brought about by their changes during the operation phase.

 Shorter release cycles:

DevOps teams remain agile in publishing software in short cycles. Shorter publishing cycles facilitate planning and risk management because incremental progress also reduces the impact on system stability.
