DevOps approach can significantly improve your software development processes by automation of deployment routine. In this article, we propose you to look at the main DevOps principles to understand what is the DevOps services and how it can help your company.
DevOps: definition and the main principles
The main challenge in software development is communication between teams. You might face the situation when the developer writes the part of code, gives it to QA engineer and starts to write a new piece of code. QA engineer needs to bother a system administrator to create the test environment. The system administrator (IT Operations) has permanent tasks like managing the infrastructure and need to leave this task for creating a new environment. As a result, we have a mess of tasks and endless throwing the code between different teams. DevOps implementation can make the process of software development smoother and simpler.
The idea is to pay attention to relationships in the teams and automate routine processes. Software development teams tired of such mess created the Agile manifesto that gave the start of the DevOps approach. An Agile manifesto has 12 rules providing a flexible attitude to software development.
The idea of DevOps is to transform these rules into a practical approach using the following principles.
- Infrastructure as Code (IaC). One of the main ideas of DevOps is to create a specially customized deployment environment. In simple words, the DevOps engineer can create the environment and the textual file with settings for this environment. Developers and QA engineers can change settings and create a new environment instance without bothering IT Operations or DevOps engineer. In this case, the whole team can spend less time on tasks.
- Continuous Integration and Deployment (CI/CD). DevOps approach provides CI/CD pipelines. Developers write the code in small chunks that is more convenient for testing and deployment. With IaC developers can independently make preliminary tests, fix some bugs and give the code to the QA engineer. After the main tests, this part of the code is added to the general part. As a result, we have a faster and smoother process.
- Continuous Monitoring and Logging. DevOps implementation can automate code deployment and infrastructure monitoring. DevOps approach provides creating self-healing infrastructure that can restarts if something goes wrong. Also, an automated system can send alerts and you don’t need to monitor all the issues manually.
Business advantages of a DevOps approach
DevOps transformation needs investments but it can reduce costs, increase competitiveness and team cohesiveness. After DevOps implementation, you’ll make releases faster than your competitors and spend less time on software development processes. Also, your team will work better because of the smooth and understandable workflow.
How to implement DevOps services?
There are two main ways of DevOps transformation. The first is to hire an in-house DevOps team which will transform the software development process. The second way is to hire a dedicated team from a Managed Service Provider (MSP). This way is more profitable because you won’t pay salaries every month after transformation. Also, you don’t need to pay attention to the location and you can use expertise for your projects from anywhere.
Summarizing, DevOps transformation is very beneficial for business because of workflow optimization. Of course, it can take time and investments but the result is worth it.
