What do you need to be DevOps?

DevOps is much more than mastering new programming tools, DevOps is an organizational culture that is revolutionizing the way teams of programmers work. Today you will see what to study to be devops.

What do you need to be DevOps?

What would you think if we gave you the formula to improve your results by investing less time in your developments?
What if you could bring this formula to your work team? This is the daily life of a devops programmer! In this post we will give you the four ingredients of what you need to be DevOps.

Test each stage of your projects

Developing quality code is a complicated and fun task in equal parts, but we are human and it is inevitable that at some point something will slip through the cracks. gazapo: a poorly implemented use case, an unconsidered condition, an unhandled exception, etc.
The further an error reaches in the life cycle of our project or product, the worse the consequences it produces.: difficulty in reproducing it, unpredictable operation, design problem on which functionality has been built, etc. Therefore it is important that develop tests that can test the use cases that you have implemented, and thus minimize a possible negative impact from early stages. All programming languages ​​have their libraries and/or frameworks for writing tests: find which one applies to your case and spend time mastering them.

Automate part of your work

The path that awaits you and that you need to be DevOps begins by recognizing the need to eliminate repetitive tasks.
Repetitive and mechanical tasks are not our forte, and Given the increasing probability of introducing errors, we must automate them as much as possible. Code integration is a great example. The code that is uploaded to the repository must always be in state dropdown; This ensures, among other things, that we can deploy in any environment in a controlled and risk-free manner, since the code has the expected quality and the final product boasts robustness. This is achieved by defining a series of actions aimed at automatically testing, measuring and integrating each change made to the code repository. You can rely on the CI/CD services offered by GitHub and GitLab, among many others, to implement Continuous Integration in your projects.

Use virtual environments

If your projects require you to generate different environments for executing tests, compilations, packaging and/or deployments, you will appreciate tools like Vagrant or Docker. Both virtual machines (VMs) and software containers can help you lift environments in a matter of minutes, and even seconds, just with a click or a command from your terminal. You don’t need to degrade your computer by installing hundreds of libraries and dependencies to try to simulate an environment: rely on these tools.

Measure and you will conquer

Monitor and obtain metrics on everything that is susceptible to it. This will help you better understand how your software is performing on the platform where it is deployed.
For example, you could have real-time access to the resource consumption (CPU, memory, network, etc.) of your software and thus identify possible optimizations to undertake. Or also, see how it behaves when it receives an increase in user traffic or detects anomalies. You can even define alerts to receive notifications of serious cases that need to be attended to urgently. You can do all this with tools like Prometheus and Grafana. This is just the beginning in the DevOps culture, but we can assure you that by applying these tips to your work, you will be able to see how your development processes will begin to significantly improve. Now you want to know what’s next? The next step will be to understand what a devops should know and thus be able to become a Full Stack DevOps and master the methods, technologies and tools that will enhance your work and that of your team.
