Software development comprises two different teams. The development team develops plans, designs, and builds the system from scratch, and the operations team tests and implements whatever is developed. The operations team gave feedback on any bugs that needed fixing or any rework required in the meantime, and the development team sits idle and waits for feedback.

This undoubtedly extends the timeline and delays the entire SDLC. There can be a case where the development team moves to the next project and the operations teams still provide feedback to the previous project, which will delay the deployment of the final code and the project's deployment.

Now DevOps came into the picture, where the development team and the operations team came together and worked in collaboration with each other.

The DevOps symbol resembles an infinity sign, suggesting that it is a continuous process of improving efficiency and constant activity.

Benefits of DevOps

• Faster, better product delivery

• Faster issue resolution and reduced complexity

• Greater scalability and availability

• Better resource utilization

• Greater automation

• Greater innovation

The DevOps culture is implemented in several phases with the help of several tools.

• Plan: This stage aids in defining the needs and values of the business. Examples of tools to track known issues and carry out project management are Jira or Git.

• Code: Software design and code coding are both parts of this phase. Examples of tools include Bitbucket, Stash, GitHub, and GitLab.

• Build: This stage involves managing software builds and versions as well as compiling and packaging code using automated tools in preparation for a later release to production. The infrastructure required for the release of a product is "packaged" in source code repositories or package repositories. Examples of tools include JFrog Artifactory, Gradle, Maven, Chef, Ansible, Puppet, Docker, and Ansible.

• Test: This phase involves continuous testing (manual or automated) to ensure optimal code quality. Sample tools include JUnit, Codeception, Selenium, Vagrant, TestNG, or BlazeMeter.

• Deploy: Tools that support managing, coordinating, scheduling, and automating product releases into production may be used during this phase. Puppet, Chef, Ansible, Jenkins, Kubernetes, OpenShift, OpenStack, Docker, or Jira are a few examples of tools.

• Operate: This phase manages software during production. Sample tools include Ansible, Puppet, PowerShell, Chef, Salt, or Otter.

• Monitor: This stage comprises locating and gathering data regarding problems with a certain software release that is currently in use. New Relic, Datadog, Grafana, Wireshark, Splunk, Nagios, or Slack are a few examples of tools.

What are Automation, Scaling, and Infrastructure

Automation: Fundamentally, automation involves carrying out repetitive tasks without human involvement so that operations can be completed quickly and efficiently.

Scaling: In DevOps, scaling is using the right tools and techniques to meet the growing load brought on by business expansion. It can be horizontal or vertical.

Infrastructure: Infrastructure consists of servers, storage, and networks that we use in organizations.

Why DevOps is Important

In the modern world, more and more businesses are embracing DevOps in an effort to speed up delivery and close the gap between their development and operations teams.

Adobe's Case Study

Years ago, when Adobe switched from packaged software to a cloud services model, it had to suddenly make a continuous stream of small software updates rather than large, semi-annual releases. This was the beginning of Adobe's DevOps transformation.

Adobe manages and automates its deployments using the end-to-end DevOps platform from CloudMunch in order to keep up the required pace. The fact that it integrates with so many different programs allows developers to keep using their preferred programs, and the multi-project view enables them to see how a change to one Adobe product affects the others.

According to the Wall Street Journal, Adobe has already been able to meet 60% more demand for app development thanks to the move, which has enabled faster delivery and better product management.

Not only Adobe, but various companies are taking advantage of DevOps culture, eg: Amazon, Netflix, Target, Walmart, Facebook, and many more.
