Who is a DevOps engineer, and when do you need one for your business?
The definition of DevOps is very complex, so it's worth creating a discussion that will help clear up many interested in this topic. There are thousands of publications on this topic on IH alone. But if you are reading this, you probably know what DevOps is, or maybe not. Let's find out!
I thought about how to make my story useful for a long time, so there will be many questions here - those I ask myself and those I ask our company's clients. By answering these questions, understanding becomes better. I will tell you why DevOps is needed from my point of view and what it is, again, from my position.
Why DevOps?
The first question that haunts everyone and always - why? Many people think that DevOps is just automation or something similar that every company already has.
After 9 years of community and methodology development, it has already become clear that this is still not marketing glitter, but it needs to be clarified why it is required. Like any tool and process, DevOps has specific goals that it ultimately achieves.
All this is because the world is changing. He moves away from the enterprise approach when companies move straight to the dream, according to a certain strategy, with a specific structure built for this.
What is DevOps, and who are DevOps engineers?
DevOps is a practice that improves the work of development and operations teams by automating repetitive tasks in software delivery processes, enhancing communication and collaboration, and shortening the software development lifecycle (SDLC).
DevOps-oriented engineers are some kind of creators and maintainers at the intersection of IT operations and software development. They understand what it takes to maintain IT infrastructure and are able to write code and deploy new services.
So, why do we need DevOps?
The current industry demand for DevOps engineers outstrips the supply. The DevOps culture is based on lean and agile principles. Being very familiar with startups' culture, these methodologies best fit their development style.
The most popular DevOps services that can bring additional value to the business are:
- continuous integration and continuous deployment (CI/CD) tools, with a focus on task automation;
- real-time monitoring, incident and configuration management;
- collaboration platforms creation;
- massively scalable and distributed systems with cloud computing, microservices, and containers implementation;
- increased communications between IT groups;
- faster time to market/lead time;
- rapid improvement based on continuous feedback in the DevOps journey;
- zero downtime in the development process with a Blue-Green deployment;
- more accurate system performance due to less manual work and more automation;
- responsibility and code ownership in development results in better dev processes;
- possibility to distribute duties among broader specific roles for more accurate performance.
Conclusion
So what do you think of DevOps now?
DevOps is needed to develop digital products. If your company does not have a digital product, DevOps is not required - this is very important.
DevOps overcomes the speed limits of a sequential software production scheme. In it, all processes occur simultaneously.
DevOps completely changes the process and organization in the company - more precisely, it does not change DevOps but the digital product. To come to DevOps, you still need to change this process entirely.
The best info you can get about DevOps is this one. So, what do you think about this post? If you know something I didn't mention here, share it in the comments below.
