What is DevOps? Its methodology, tools and everything you need to know

Authored by chintan on March 25, 2020

The adoption of DevOps, agile and public cloud services among businesses worldwide is increasing by the day. These are seen as the major shift in enterprise IT, and as the next wave after the Internet. Thanks to digital democratization, due to which businesses have to be nimble to remain competitive. That said, security threats and cybercrime continue to outsmart this business despite having cutting-edge security wall around them. To this end, DevSecOps was born to bridge the security gap into DevOps, just as DevOps bridged the development and operations divide.

What is DevOps?

DevOps is the practice of operations and development engineers participating together in the entire service lifecycle, from design through the development process to production support.

DevOps is also characterized by operations staff making use of similar techniques like that of the developers for their systems to work and a lot of process automation as well.

What Are The Strategies in DevOps?

Continuous Integration: 

Continuous Integration (CI) is the practice of automating the build and testing of code when developers integrate the code and share it across the repository. The changes in the code are sent to the repository and tracked using the version controls once after every task is completed. The changes in the code are pulled from the shared repository, tested and validated to the main branch which is  also called a trunk or master branch.

Continuous Integration utilises a centralized server which continuously monitors and  pulls in the changes done in the source code. When a failure or error occurs, it’s easy for the development team as they are a part of the built from the initial stages, identifying the bug and fixing the build is the developer’s responsibility before he makes further enhancements in the code.  The most important advantage of continuous integration is, finding errors becomes easier. Since all the changes reflect clearly, pinpointing a specific change is quick to identify.

Continuous Planning:

Continuous Planning involves expert DevOps consultants who set expectations and milestones by evaluation of existing processes and systems to strategize a complete roadmap. To achieve seamless DevOps automation, we use industry-leading software tools and frameworks such as Docker, Puppet, Selenium, etc.

Continuous Delivery:

Continuous delivery is an ongoing DevOps practice of building, testing, and delivering improvements to software code and user environments with the help of automated tools. The key outcome of the continuous delivery (CD) paradigm is code that is always in a deployable state.

At its core, continuous delivery follows a streamlined process commonly known as the continuous delivery pipeline. The pipeline begins with the developer committing his code to the source repository. For every check-in, automated tests (unit, regression, performance, etc.) are run to ensure high-quality code. Once the code is verified, the executables are deployed automatically to an intermediate environment such as staging, integration, or UAT. At this point, the code is ready to go into production, and can be pushed live on-demand.

Continuous Monitoring:

Continuous monitoring refers to the process and technology required to incorporate monitoring across each phase of your DevOps and IT operations lifecycles. It helps to continuously ensure the health, performance, and reliability of your application and infrastructure as it moves from development to production. Continuous monitoring builds on the concepts of Continuous Integration and Continuous Deployment (CI/CD) which help you develop and deliver software faster and more reliably to provide continuous value to your users.

What Types of Services are Provide in DevOps?

DevOps provides a set of flexible services designed to enable companies to rapidly and reliably build using DevOps practices. These services simplify provisioning and managing infrastructure, deploying application code, automating software release processes, and monitoring your application and infrastructure performance.
