Let's start with the basics: who are DevOps?
DevOps is not a job title or a set of tools. It is approach to development, which unites developers (Dev) and system administrators (Ops)to release products faster and more reliably together.
If earlier a programmer wrote code, and the admin then "somehow" deployed it, now these processes are connected. DevOps is about teamwork, automation and speed.
The main idea of DevOps
"Write code - test - deploy - improve. All this should work as a single flow."
The goal is to make sure that updates can be released often and without painDevOps helps turn chaos from “works for me” into a stable and predictable process.
Basic principles of DevOps
Automation — everything that can be automated is automated: code assembly, tests, deployment, monitoring.
Continuous Integration (CI) — each commit passes tests and verification, after which the code is merged with the main branch.
Continuous Delivery (CD) — after successful assembly and testing, the project is automatically deployed on the server.
Monitoring and feedback — systems constantly monitor the status of the project and quickly respond to failures.
Let's consider what a beginner needs to know.
Even if you are not a DevOps engineer yet, understanding these things will help you work better in a team:
Git and CI/CD — how the code travels from the commit to the server.
Docker and containerization — how to isolate the application from the system.
Clouds (AWS, Yandex Cloud, Azure) — where modern projects live.
Infrastructure as code (Terraform, Ansible) — automation of server configuration.
Monitoring (Grafana, Prometheus) - to know what works and what doesn't.
Safety — management of keys, rights and updates.

Without DevOps:
The programmer wrote the code.
Sent to the administrator.
The administrator has configured it manually.
Something broke, and nobody knows where.
With DevOps:
The code is pushed to Git.
The CI system runs the tests.
Docker is building a container.
CD rolls everything out to the server.
Grafana shows that everything is working.
All this without nerves, night deployments and "why isn't the product like mine?".
Tools that are worth at least knowing by name
Category | Examples |
|---|---|
CI/CD | GitHub Actions, GitLab CI, Jenkins |
Containers | Docker, Podman |
Orchestration | Kubernetes |
Infrastructure | Terraform, Ansible |
Monitoring | Grafana, Prometheus |
Safety | Vault, Snyk |
DevOps is not about magic or “server boredom.” It's about speed, reliability and cooperation. Even if you are just starting your journey in development, understanding DevOps will give you a huge advantage — you will understand how your code turns into a real product.
