The value of a successful DevOps model
If you’re working in the digital product field, It is definitely worth being familiar with the concept of DevOps, since it can result in simplified operations and processes, a more efficient team, and greater success with your products.
DevOps is a combination of Development, Operations and QA. When used properly, the right DevOps will have a positive impact on your users, as well as your internal team.
The purpose of DevOps is to streamline processes and operations so the development teams can spend less time on processes or tools, and more on developing solutions and delivering value.
DevOps goals include the automation of the following:
QA & Testing
Automated testing is about running tests automatically to make sure new code hasn’t caused any problems. Often known as test driven development, or TDD, this development approach has the engineering teams writing tests alongside whichever feature they are working on so the code gets tested in units.
Developers write their own unit tests for whichever feature they are working on and run tests to see how the feature performs. If the feature fails, the team can work on further development and then redo the test. In DevOps, new code testing means you will know immediately if any new functionality or feature breaks the existing code, and there are various tools DevOps engineers use to do this.
Integration and Delivery
This process means continuously adding new code into the main codebase and usually works alongside continuous delivery to maximise efficiency.
A poor DevOps process can mean out-dated technology, messy legacy code, poor team communications, and the need to ship software less frequently. Whereas a good DevOps process can lead to more frequent shipping of features, and result in a far more scalable and sustainable growth strategy for a project.
Continuous delivery increases responsiveness. When a new feature is deployed to production, problems can be solved faster and bugs fixed more quickly. Risk and waste are reduced because any issues show up immediately and can be fixed sooner.
If continuous delivery is not used, there can be a lot of stress and panic around release day and things often go wrong. With continuous delivery, releasing small releases more frequently, the whole process is smoother and far less fraught for the team.
Switching to continuous delivery can take some adjustment. Changing mindsets, dealing with legacy code and overcoming various hurdles in the organisation can complicate the process. However, if everyone has an incentive to change to continuous delivery and understands the benefits, it is certainly doable.
When implementing a new DevOps process, it is crucial to make sure everybody is on the same page, since you are all working on the same goal and wanting the same positive results at the end of it.
If you are from a product background, your technical leaders might be reticent about such a change and you will not have direct control over the engineering team’s culture either. It is ultimately down to the technical leaders to implement these changes although you can influence things from the side-lines.
It is therefore important to clearly communicate the DevOps goals and the reasons you want to implement a change.
