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. Services of DevOps listed below in details:   

Infrastructure Management

Infrastructure management is a fundamental building block for any organization striving to achieve a DevOps methodology. Our DevOps services can work with your company to utilize the cloud in improving scalability and reliability.

Configuration Management

Configuration management standardizes resource configurations and enforces their state across IT infrastructure. Senior DevOps engineers can help your company do this in an agile and automated manner.

Code Inspection & Integration

Clean code is the foundation of continuous integration. Experienced DevOps engineers can work with your team to help test and improve code, verify artefacts for deployment, and help ensure quality build and code reports.

DevOps Automation Service

Automating the deployment process makes companies more efficient and agile while reducing overall production time and the associated risk.

Staff Augmentation

One of the most significant hurdles when building out a DevOps team is finding experienced talent. Our DevOps engineers are among the best in the world, ready to join your team and contribute immediately.

Virtualization

Through virtualization, developer and IT teams are able to use the same compute and network environments, further breaking down barriers in a DevOps organization and reducing costs substantially.

DevOps tools allow organizations to create and improve products at a faster pace than they can with traditional software development approaches. And, it’s gaining popularity at a rapid rate.

There are some categorized DevOps tools below:

To Code

Git:Git is a version-control system for tracking changes in computer files and coordinating work on those files among multiple people.” So that means that the most basic and important function of Git is to allow teams to add (and merge) code at the same time to the same project. By adding this ability to projects it makes teams more efficient and gives them the ability to work on bigger projects and more complex problems.

Jira: JIRA is a tool developed by Australian Company Atlassian. The basic use of this tool is to track issues and bugs related to your software and Mobile apps. It is also used for project management. There are various project management tools that are as good as Jira but it is Jira’s simplicity that wins the hearts of its users. The JIRA dashboard consists of many useful functions and features which make handling of issues easy.

To Build

Werf: Werf is a GitOps tool that integrates nicely into any CI/CD system and provides a complete application lifecycle management, allowing you to:

  • build and publish images,
  • deploy an application into Kubernetes,
  • cleanup unused images by policies.

Buildout: Buildout is an open-source software build tool. Buildout is created using the Python programming language. It implements a principle of separation of configuration from the scripts that do the setting up. Buildout is primarily used to download and set up dependencies in Python eggs format of the software being developed or deployed. Recipes for build tasks in any environment can be created, and many are already available.
