Introduction

“DevOps” is an emerging model that allows effective collaboration of development and Operations team so that they can build, test, and release software faster and more reliably.

Traditionally in an organization, where a waterfall method is followed in which the development team tests the new code in an isolated development environment for quality assurance. But since Agile and continuous workflow have taken over the world of software development, this model is out of the game. Short sprints and frequent releases occurring every two weeks or even every day require a new approach and new team roles.

What is DevOps?

DevOps is Development and Operation’s Collaboration, It’s a Union of Process, People and Working Product that enable continuous integration and continuous delivery of value to our end users. With DevOps, organizations can release small features very quickly and incorporate the feedback which they receive, very quickly. Also, it minimizing the risk factor by continuously delivering and getting end-users and stakeholders feedback at the early stages.

DevOps is here to improve the efficiency of the whole development team by introducing short releases and streamlining both operations and development teams. Moreover, DevOps is all about introducing more automation tools for testing, building, and deploying software to the processes of the development team.

How DevOps Works?

DevOps is deep integration between development and operations. Understanding DevOps is not possible without knowing how it works.

Here is a brief information about the Continuous DevOps life-cycle:

1. Development– In this DevOps stage the development of software takes place constantly. In this phase, the entire development process is separated into small development cycles. This benefits DevOps team to speed up software development and delivery process.

2. Testing– QA team use tools like Selenium to identify and fix bugs in the new piece of code.

3.Integration– In this stage, new functionality is integrated with the prevailing code, and testing takes place. Continuous development is only possible due to continuous integration and testing.

4.Deployment– In this phase, the deployment process takes place continuously. It is performed in such a manner that any changes made any time in the code, should not affect the functioning of high traffic website.

5.Monitoring– In this phase, operation team will take care of the inappropriate system behavior or bugs which are found in production.

What are the benefits of DevOps?

DevOps allows Agile Development Teams to implement Continuous Integration and Continuous Delivery. This helps them to launch products faster into the market. DevOps is necessary for anyone looking to stay top of the game in a competitive market, and aims at delivering the best in class features to end-users on time.

Below are some of the benefits of adopting DevOps

  • Ensure faster deployments- DevOps ensure faster deployments, with DevOps you can deploy in 48 hours or less which earlier used to take months. Your customers will not only be excited about the speed of delivery of new features and updates, but your position in the competitive market is kept solid.
  • Improved product quality- One of the key pillars of DevOps is the cooperation between operations and development, as well as the regular capturing of feedback. This means closely monitoring the quality of output, which is likely to cause significant improvements.
  • Fewer Failures- DevOps offers significantly lower failure rate of new releases. With DevOps, flaws are constantly tested through automation, allowing teams more time that can be used to frame new ideas.
  • Maintainability- Effortless process of recovery in the event of a new release crashing or disabling the current system.
  • Improved Quality- DevOps helps the team to provide improved quality of application development as it incorporates infrastructure issues.
  • Stabilize work environment- With DevOps’ best practices, you can safely improve your workplace stability using a steady and balanced approach that limits the tension normally experienced between teams when new releases, features, and bug fixes are due.
  • Minimize Cost- With proper DevOps strategies in place, it’s possible to cut down the production and management costs of your departments because both maintenance and new updates are unified under a single umbrella.
  • Security- While implementing automation Security is a very important factor, By Following DevOps model and using Infrastructure as code and by doing automation of process and compliance policies, one can take control security configuration.

Now let’s quickly walk through the list of list of 10 top DevOps tools that focuses on every element of DevOps – a list that shows how these tools lead to improved collaboration and transparency, as well as faster development and more resilient architecture.

Kubernetes provides exceptional developer user experience (UX), and the rate of innovation is phenomenal.

Kubernetes extends how we scale containerized applications so that we can enjoy all the benefits of a truly immutable infrastructure. The general rule of thumb for K8S: if your app fits in a container, Kubernetes will deploy it.

Features-

  • Scale your application as needed from command line or UI.
  • Roll out changes that monitor the health of your application—ensuring all instances don’t fail or go down simultaneously. If something goes wrong, K8S automatically rolls back the change.
  • Containers get their own IP so you can put a set of containers behind a single DNS name for load balancing.
  • Automatically mount local or public cloud or a network storage.
  • Create and update secrets and configs without rebuilding your image.
  • Manage your batch and Continuous Integration workloads and replace failed containers.
  • Automatically schedules containers based on resource requirements and other constraints.
