If you work in the IT services or development field or even are interested in one, you must have heard the term – DevOps. But many of us confuse it with something like a tool or technology. The first thing to note is that DevOps is not something that can be learned by taking a course; you need to know more to call yourself a DevOps services engineer or a DevOps developer. DevOps is more like a framework or a way of working in a high-speed environment. So, what is DevOps exactly? The term is the combination of two teams that we see in any developmental life cycle, the development, and the operations team.
The problem as of now is that both the teams mentioned above work separately and virtually isolated from each other. The development team has to roll out new feature updates and send them to the operations team. The operations team needs to update the servers and any of the hardware required for running those new features. The problem for any of the teams is the lack of awareness about each other’s progress. It makes it difficult for both of them to roll out better features and work fast. The concept of DevOps is solving this problem by integrating both of the teams. DevOps methodology makes sure that both teams are aware of what the other is doing and that they work in tandem.
So, what does the concept of DevOps consist of? Here are the steps involved in a typical software development cycle:
4. Release and deployment
6. Feedback and optimization
In a typical lifecycle, the steps are like mentioned above. The planning, developing, and testing are the jobs of the development team, and release and deployment, monitoring, feedback, and optimisation are the jobs of the operations team. But what differs in the DevOps cycle is that the flow is cyclic. The planning, development, and testing are done by keeping in mind the feedback and deployment requirements provided by the operations team. The image given below encapsulates the concepts involved in DevOps services pretty well.
Here are the few benefits of using DevOps methodology for development:
· Lower failures: With the two teams working together, the number of failures, due to any of the teams, can be avoided. For example, the deployment can be made less erroneous if the operations team knows exactly what will be needed at the time of release.
· Better quality: Working together will ensure better quality, as the development team now knows the feedback received and the deployment specifications.
· Faster releases: With the code developed by taking inputs from the operations team, the features can be released faster, as the modules are readily available.
· Lower costs: The increased communication reduces the cost of deployment as nothing extra is needed.
· Increased frequency of releases: DevOps service pipeline makes the overall release time lower. With DevOps, companies can release hundreds or even thousands of features in a day.
· Easy maintenance: Again, with operational teams working onboard with the development team, the code can be maintained easily on and off the server.
Although each team has its variants of the cycle, here are the principles which you need to keep in mind while taking your team towards a DevOps methodology.
- Automation and reliability: This principle allows you and your team to adjust towards an agile development cycle throughout the lifetime of the product. By automating the process by several repetitive, but reliable sub-processes, the company can develop a continuous pipeline through which releases can be made much faster.
- To keep a check on operational quality: When the frequency of feature releases is more, it is always important to keep the development quality consistent. A company must keep an eye on the key delivery quality and DevOps metrics for performance.
- Develop and test against a production-like environment: If you need to get the features released quickly without any problems from the operations team, the developers must keep the deployment specifications in mind so that the environment adaptability is not an issue.
The DevOps methodology is an efficient methodology that is being adopted by many big companies. Getting your development and operations team working together is challenging at first, but it is worth the effort.
