DevOps – Development & Operations – top DevOps technologies, tools and benefits
December 20, 2021
IT buzzwords change like the wind. From CI (Continuous Integration) to TDD (Test Driven Deployment), it is recommended to always stay updated with latest trends (Technologies) that might increase your productivity and improve the process overall.
Today let’s speak about the buzz word “DevOps” because a lot of people are not actually sure is it a movement? A new process or technology? A job title? Or just a way of thinking? Also we will look at the top DevOps technologies, tools and benefits.
What is DevOps?- DevOps is the union of people, process and products to enable continuous delivery of value to our end users.
- DevOps is not just automating a pipeline so we can quickly deliver software. Our goal is to deliver value.
- If the value only reaches the Dev and QA environments but is held up before reaching production where it can be realized by our end users, we are still failing.
- DevOps improves IT's Cadence and Velocity for that agile, lean and ITSM practices are also needed.
DevOps is also about a mindset, a culture that is made up of processes and practices that bring development and operations teams together within a company to develop and deploy software, with maximum efficiency and minimal interruptions.
In other words, DevOps is a cultural shift in collaboration between development, operations and testing. Sounds simple, but in reality is not. So, let’s look at main responsibilities of DevOps engineer to understand it better:
- Code: Code development and review, version control tools, code merging
- Build: Continuous integration tools, build status
- Test: Results determine performance
- Package: Artifact repository, application pre-deployment staging
- Release: Change management, release approvals, release automation
- Configure: Infrastructure configuration and management
- Monitor: Applications performance monitoring, end user experience
- Automate: The processes in software delivery.
- Continuous delivery: frequent and short iterations, releases
Why DevOps is important suddenly?

Strong IT performance is a competitive advantage! The need for DevOps was born from the increasing popularity of agile software development, as that tends to lead to an increased number of releases. DevOps engineer normally works a lot with tools such as Docter- containerization Jenkins- continuous integration, etc. The goal of DevOps is to establish an environment to release reliable applications faster and more frequently.
