Throughout the application lifecycle’s plan, build, deliver, and operate phases, DevOps has an impact. Each phase is interdependent on the others, and the phases are not divided into roles. Each position is involved in each phase to some level in a true DevOps culture.

• Plan

DevOps teams use the plan phase to brainstorm, define, and describe the features and capabilities of the apps and systems they’re developing. They keep track of progress at all levels of granularity, from single-product projects to activities that span numerous product portfolios. DevOps teams prepare with agility and visibility by creating backlogs, tracking issues, managing agile software development with Scrum, using Kanban boards, and visualising progress with dashboards.

• Develop

The develop phase encompasses all aspects of coding, including team members’ writing, testing, reviewing, and integrating code, as well as converting that code into build products that can be deployed in multiple settings. DevOps teams strive for quick innovation while maintaining quality, stability, and productivity. They accomplish this by utilising highly productive technologies, automating monotonous and manual tasks, and iterating in small increments via automated testing and continuous integration.

• Delivery

The process of consistently and reliably putting applications into production environments is known as delivery. The deployment and configuration of the fully regulated core infrastructure that makes up those environments are also part of the deliver phase. Teams create a release management procedure with explicit manual approval phases during the deliver phase. They also set up automatic gates to transport applications through different phases till they’re ready for clients. These processes become scalable, repeatable, and controllable when they are automated. DevOps teams can deliver regularly with comfort, confidence, and peace of mind in this way.

• Operate

In a production environment, the operate phase entails maintaining, monitoring, and debugging applications. Teams that use DevOps principles strive for system stability, high availability, and minimal downtime while also ensuring security and governance. DevOps teams strive to discover issues before they have an impact on the customer experience and to promptly resolve them when they do. Rich telemetry, actionable alerting, and full visibility into apps and the underlying system are all required to maintain this vigilance.
