Quickest Way to Establish DevOps for Smooth SDLC: It’s Not What You Think!

What comes to your mind when you hear DevOps? I know what all names that will pop up in your mind: Puppet, Jenkins, GIT, Chef, Docker, Selenium, AWS etc. All the DevOps tools that people in the software development industry worship for making SDLC easier. But are these tools the quickest way to establish DevOps for SDLC in your company?

To answer this question, we’ll dive deeper into the reason behind its existence and how should the businesses approach DevOps to establish it the right way.

We’ll talk about the following topics in detail:

  1. Pre-DevOps era: The Waterfall Model for SDLC

  2. DevOps: One solution for all SDLC problems

  3. Tools that power DevOps

  4. Quickest way to establish DevOps for smooth SDLC in your company: The secret is out!

If you’re a professional already working in the DevOps industry, by the end of the article, you’ll know the efficient way your team should be working with DevOps. If you’re a student or aspiring DevOps professional, you’ll know that one thing you should be focusing on when it comes to establishing DevOps in any company.

Pre-DevOps era: The Waterfall Model for SDLC

Waterfall model is a traditional way of developing a software.

The above image explains the phases involved in the waterfall SDLC approach. First the complete requirement is gathered and SRS is developed. Then the system is planned and designed using the SRS. In phase 3, the implementation of the System takes place. Thereafter, the system is tested and its quality is assured so that it can be deployed to the end users. In the last phase of waterfall model for SDLC, the regular maintenance of the system is done.

Well, the waterfall model worked all fine for quite a few years but it had its own challenges. Both developer and operation teams had few complains:

For Developers team:

  1. Code deployment time was huge.

  2. Pressure of work because of old, pending and new code was high as the deployment time was high.

For Operations team:

  1. It was difficult to maintain ~100% up-time of the production environment.

  2. Infrastructure Automation tools were not very effective.

  3. Number of severs to be monitored keeps on increasing with time and hence the complexity.

  4. It was very difficult to provide feedback and diagnose issue in the product.

To address such issues, DevOps was found for better and efficient SDLC.

DevOps: One solution for all SDLC problems

DevOps integrates developers and operations team to improve collaboration and productivity. DevOps is a culture where the entire team from developers, system admins, QA’s, testers etc. has end-to-end responsibility for Software Development.

From gathering the requirement to development, to testing, to infrastructure deployment, to application deployment and finally monitoring & gathering feedback from the end users, then again implementing the changes. They take full responsibility and it’s a never ending cycle just like this image below:

DevOps lifecycle stage:

  1. Continuous Development

  2. Continuous Integration

  3. Continuous Testing

  4. Continuous Monitoring

  5. Virtualization and Containerization

DevOps found solution for developer’s issues with ‘continuous integration process’. This way quick deployment of code was ensured along with faster testing and feedback process. Now they just need to focus on new codes.

For the operations team, DevOps’ containerization method ensures there is a simulated environment created to run the software. Configuration management helps the operations team to proactively manage their infrastructure and through continuous monitoring, effective administration is assured.

Tools that power DevOps

DevOps tools help in achieving automation at various stages which helps in achieving Continuous Development, Continuous Integration, Continuous Testing, Continuous Deployment, Continuous Monitoring to deliver a quality software to the customer at a very fast pace.

Some of the best DevOps tools today are:

  1. Gradle

  2. Docker

  3. Jenkins

  4. Git

  5. Bamboo

  6. Kubernetes

  7. Puppet Enterprise

  8. Ansible

  9. Nagios

  10. Raygun

So you must be thinking, of course, to establish DevOps for SDLC in your company, you just need to use these tools! Well, Yes and No both.

Yes, because these tools power DevOps. No, because these tools are very useful but not really necessary. DevOps is not simply combining Development & Operations teams to use tools. DevOps is a culture which needs to be adopted.

Quickest way to establish DevOps for smooth SDLC in your company: The secret is out!

When companies or professionals come to me for DevOps consultation, they are always eager to know about the tools which they need to use. I always tell them that tools will come and go, it’s important to keep DevOps’s core purpose in mind to establish it successfully in your company.

DevOps core purpose is to bridge the gap between what the client requirement is and what the development team has delivered.

The secret to successfully establish DevOps for smooth SDLC in your company is ‘Communication’!

Communication is an important aspect when you need to know as to what is required to get the job done! As soon as you get to know about the requirements, write it down and make it accessible to all the team members so that each one can visit it as and when required.

Wrapping up…

I’m in favour of all the wonder automation tools for DevOps, they have made SDLC an efficient process. All I’m advocating is that a DevOps team should first focus on proper communication, automation tools come second. Communication is the core of DevOps.
