Definition of DevOps
DevOps is the combination of people, process, and technology to continuously give value to consumers. It is a
compound of development (Dev) and operations (Ops).
What does DevOps and devops engineer course imply for organisations? DevOps enables formerly separate
roles—development, IT operations, quality engineering, and security—to coordinate and cooperate to create
better, more dependable products. Adopting a DevOps culture, as well as DevOps methods and technologies,
allows teams to better respond to customer requests, boost confidence in the applications they produce, and
achieve business goals more quickly.
The application lifecycle and DevOps
● DevOps has an impact on the application lifecycle throughout the phases of plan, build, deliver, and
operate. Each phase is dependent on the others, and they are not role-specific. Each position in a real
DevOps culture is involved in each phase to some level.
●
DevOps teams ideate, define, and explain the features and capabilities of the applications and systems
they are developing during the plan phase. They track progress at both low and high levels of granularity,
from single-product activities to tasks 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.
●
The develop phase involves all elements of coding, such as team members developing, testing,
reviewing, and integrating code, as well as building that code into build artefacts that can be deployed in
multiple contexts. DevOps teams strive to develop quickly while maintaining quality, stability, and
productivity. They accomplish this by employing highly productive tools, automating monotonous and
manual tasks, and iterating in tiny increments via automated testing and continuous integration.
●
Delivery is the process of consistently and reliably distributing software into production settings.
Deploying and configuring the fully regulated core infrastructure that makes up those environments is
also part of the deliver process. Teams create a release management procedure with explicit manual
approval phases during the deliver phase. They also set up automated gates that transport applications
through several phases before they are made available to clients. By automating these procedures, they
become scalable, repeatable, and controllable. DevOps teams can therefore deliver regularly with ease,
confidence, and peace of mind.
●
In the operational phase, applications in production settings are maintained, monitored, and
troubleshooted. Adopting DevOps principles requires teams to work together to achieve system stability,
high availability, and zero downtime, all while reinforcing security and governance. DevOps teams strive
to discover issues before they have an impact on the customer experience and to mitigate difficulties as
rapidly as possible when they do emerge. To maintain this vigilance, robust telemetry, actionable alerting,
and complete visibility into applications and the underlying system are required.
