IT departments these days are feeling the heat to make processes faster and more efficient. That’s where the concept of “DevOps” enters the picture. The name comes from streamlining software development, which is basically the act of writing computer code, with IT operations. These teams test, deploy, as well as monitor new applications or platforms. This is now an important part of the operations of many companies these days. We can no more afford to be driven by processes that can be an obstacle to business growth.
In the fast paced digital age, IT is an equal business partner than just a support function. In order to support business growth, IT has to culturally align and deliver at the speed at which business thinks. While there are several tools and methodologies around this, there is a huge cultural change that the IT team needs to adopt and one of the changes is the DevOps methodology. A single, cross functional team that works collaboratively and is fully accountable and agile to business requirements. The biggest benefit of Devops is the ability to make changes as we go along. It allows businesses to be flexible when it comes to requirements. Devops offers you to work together in an agile manner. Through this collaboration between development and operations, the effort in meeting and delivering business requirements as well as the time to market gets reduced. It basically validates what the business wants. Another big advantage is that you don’t have to rewrite code. You get microservices available through the community.
Bhavesh Lakhani, Chief Technology Officer (CTO) at SBI Mutual Fund talks about DevOps in the book Titled “Accelerating Enterprise Innovations” and says that it helps increase business value enormously. Excerpts from the book:
Typically, in the absence of DevOps, we observe that there are often apprehensions around scale and stability when releasing new features. There are silos and the development teams are measured on the updates they deliver to users while the operations team is measured on the health of the system and capacity management. The typical approach is that the code is thrown over the wall to the IT Operations team at the end of coding and lacks accountability.
In a DevOps environment, on the other hand, the entire team is responsible for delivering both new features and stability. The combination of a shared code base, continuous integration, test-driven techniques and automated deploys amongst other things, helps identify the problems—in application code, infrastructure, or configuration.
This leads to direct business benefits as problems tend to be less complex because change sets are smaller. DevOps engineers can exploit real-time data into the performance of their systems to quickly understand the impact of application changes. And resolution times are faster because team members don’t need to wait for a different team to troubleshoot and fix the problem. Also, automated deployments and standardized production environment which are key aspects of DevOps lead to predictable deployments and free people from routine repetitive tasks to go do more creative things thus leading to a better job satisfaction. The other benefits include faster time to market and better management of potential scope-creeps. He points out the following benefits of DevOps:
- Faster Time to Market
- Scalable and stable operating environments
- Better team communication and collaboration
- More proactive planning and reduced reactive fix/maintain cycle
