In the world of modern technologies, software development is one of the fastest-evolving areas. Through the last decades, even development approaches changed and brought out new methodologies. The most popular one today is DevOps.
Sometimes DevOps is considered as just a term for particular tools, in fact being a whole philosophy reflecting the necessity of close collaboration between the teams responsible for application delivery. The methodology is based on 3 principles:
Some business owners have already heard of DevOps here or there and came to a conclusion that DevOps is some kind of technological stack: CI servers, development platforms, automatic deployment tools and so on. The truth is, DevOps implies using some particular tools but is not limited by them. Without the above-mentioned principles and your team sticking to them, such tools can be useless.
The same is true for people who think that implementing CI/CD pipelines is enough to implement DevOps. The key principle still lies in the area of team communication: everyone who works on an application must exchange information. Otherwise it will make no difference to the traditional development.
Another trap one can fall into is thinking that hiring a few DevOps engineers will solve all the problems. Actually, having an outsource DevOps team is a good idea — until your own developers accept the described principles and use the same instruments. You have to adjust your processes and culture first. And a good professional can help here, if you accept their advice.
Though DevOps tools don’t equal the DevOps approach, it’s necessary to adopt the corresponding stack.
DevOps implies working with the cloud infrastructure. The most popular cloud service is AWS. Besides a public cloud, AWS provides specific APIs and various web-services. Cloud infrastructure helps to make development teams’ collaboration easier and application deployment smoother. Besides, AWS offers a huge number of useful services for almost everything from data storage to CI/CD orchestration.
Kubernetes is another great tool which leverages DevOps. It helps to wrap services into containers and manages everything connected with them.
Also, DevOps uses tools for deployment automation, cloud infrastructure management (for example, Terraform), CI/CD automation software like Jenkins or TeamCity and several others. Most of them concentrate on the automation of any development or operating process that can be automated, because this is how continuous integration and delivery is achieved.
As we said before, adopting the proper tooling is only the first step for implementing DevOps into your processes.
In traditional development, the team is usually divided into groups: developers, QAs, system administrators (if any), management and so on. The development cycle — whatever methodology is applied — in this case is divided into consistent steps: creating a technical task, prototyping, writing code, testing, etc. But going from step to step, some information about the application (and the desired result) is lost, because no one cares about explaining to colleagues what was done and why.
No one sees the process in the whole, probably except for the project manager, and doesn’t understand its purpose. Such miscommunications may cause undesired process interruptions, restrain the development process and move the deadlines further and further.
DevOps implies tight connections and interactions between the developers and other teams. And that’s how it works: when developers, QAs, and system administrators know what’s happening in other teams, they’re able to think in advance and avoid many annoying problems. The best you can do to support the cooperation is to hire or train DevOps professionals who will think as developers and system admins at the same time.
Of course, a few DevOps engineers can’t ensure your whole development cycle automatically becomes DevOps. Every team member must adopt the corresponding instruments and remember about communication.
In Setronica, all software engineers and other professionals stick to the DevOps approach and have perfected all the corresponding tools and skills.
So, once again: why is it worth using the DevOps approach? The short answer is that DevOps allows the team to work faster and make fewer mistakes. And if you dive in deeper, you’ll see that this approach emerged in response to the developers’ and users’ needs for quite a reason. The efficiency of DevOps is proven by the following points:
Thus, DevOps helps optimize business and development processes, cuts costs and saves time. With DevOps tools and way of thinking, any team can perform the maximum efficiency with minimum expenses.
In Setronica, we think that DevOps is the most profitable development approach. It’s not a silver bullet, but it proved its efficiency for many companies. That’s why we adopted the DevOps tools and practices and keep sharpening our professional skills.
