“DevOps transformed the tradition of how IT is organized, how engineers interact”
DevOps. DevOps Engineer, DevOps developer, DevOps architect blah blah blah......... In recent days we are hearing the term DevOps once in a day. But the majority of people doesn't have any idea about what actually DevOps is.
DevOps is a technical jargon in recent times and a lot of people and organizations are using it frequently. There is no one-word explanation for "What is DevOps". It is all about awareness, experience and understanding of the culture of the organization and how it fits in the current era.
Let's make a sense that DevOps is not a technology, tool or any innovative framework. It is more of a Philosophy and concept. We should also use it as a culture of an organization where application lifecycle management is in the centre of focus. However, DevOps is made of refactoring two words, Development and Operations. Both the team has different responsibilities and functionalities in the Application release management life cycle. It is more related to continuous communication, collaboration, feedback between different stakeholders such as developers, testers, infrastructure management team, configuration management team, deployment team etc.
We are Also heard about Agile. Agile software development is similar to DevOps. However, agile development is more bothered with changing the way software developers and IT operations think, while DevOps involves actual changes in organizational structure, culture and practices.
As per the law of DevOps culture, a single group of Engineers (developers, system admins, QA’s, Testers etc turned into DevOps Engineers) has end to end responsibility of the Application (Software) right from gathering the requirement to development, to testing, to infrastructure management and deployment, to application deployment and finally monitoring & gathering feedback from the end-users, then again implementing the changes.
These tools are used in various stages of DevOps. DevOps periodic rotation can be broadly broken down into the below DevOps Stages:
Virtualization and Containerization
These stages are the backbone to achieve DevOps as a whole.
CALMS is a conceptual framework for the integration of development teams, infrastructure teams, functions and systems within an organization. The CALMS framework is often referred to as a maturity model, helping managers to evaluate whether or not their organization is ready for DevOps and if not, what needs to change.
The five blocks of the CALMS framework for DevOps are:
Culture - there is a culture of shared responsibility.
Automation - team members discover different ways to automate as many tasks as possible and are comfortable with the idea of continuous delivery.
Lean - team members can be able to visualize work in progress (WIP), limit batch sizes and manage queue lengths.
Measurement -Analyze operations and development at regular intervals to continuously optimize DevOps implementation.
Sharing - encourage ongoing communication between development and operations.
In conclusion, DevOps is an approach and a culture that improves the collaboration between Development and Operations teams. Enabling DevOps improves the speed of the development and delivery according to the business and customer needs.
