Surely everyone has had a situation where the application suddenly stopped working, the site took a long time to load, or the service became unavailable at the most inopportune moment.
The user sees only one thing — "something is not working." But to ensure that such situations occur as rarely as possible, it is worth the work of a DevOps engineer.
Who is DevOps?
In simple terms, DevOps is a specialist who helps a developed product work stably, quickly and safely.
Developers create new features, testers check their quality, and DevOps makes sure that all these changes get to users without failures.
He sets up servers, automates processes, monitors the system, monitors updates, and helps the team respond quickly if something goes wrong.
Imagine a large online store on the day of a massive sale. Thousands of users log in at the same time, place orders and make payments. If the infrastructure is not ready for such a load, the site may slow down or stop working altogether.
It is DevOps that helps to prepare the system for such loads and make sure that the service remains available even in the most stressful moments.
This profession is suitable for those who like to understand how everything works "under the hood", are interested in servers, cloud technologies, automation and want to understand how modern digital services work.
If you want to develop in this direction, start from the base.:
• Learn the basics of Linux and working with the command line.• Get to know the networks and how the Internet works.• Master Git and the basics of programming (Python or Bash).• Deal with Docker and Kubernetes.• Learn the basics of cloud technology and CI/CD.
Books that will help you get started in DevOps:
• The Phoenix Project — Gene Kim, Kevin Behr, George Spafford. A great introduction to DevOps through the real story of creating an IT product.
• The DevOps Handbook — Gene Kim and co-authors. A practical guide to modern DevOps approaches.
• Docker Deep Dive — Nigel Poulton. A simple explanation of one of the most sought-after technologies in DevOps.
• Kubernetes Up & Running — Brendan Burns, Joe Beda, Kelsey Hightower. For those who want to understand how modern services work in a cloud infrastructure.
Behind every stable application that runs 24 hours a day and can withstand millions of requests, there is a huge team effort. And one of the key roles in this team belongs to the DevOps engineer.
Users rarely notice the good work of DevOps. But it is thanks to her that digital services remain available when they are needed most.
Когда слышишь слово «менеджер», может показаться, что это человек, который только проводит встречи и раздает задачи.
На самом деле в IT роль менеджера гораздо шире.
Хороший IT-менеджер — это человек, который помогает команде работать эффективно, а идеям превращаться в реальные продукты.
Он не пишет код каждый день, но создает условия, в которых разработчики, аналитики, QA-инженеры и другие специалисты могут сосредоточиться на своей работе и достигать общего результата.
В IT есть несколько направлений менеджмента, и у каждого своя роль.
Team Lead / Tech Lead помогает команде решать технические задачи, делится опытом, поддерживает коллег и помогает принимать сложные инженерные решения.
Project или Delivery Manager следит за тем, чтобы проект двигался по плану: задачи выполнялись вовремя, команда была обеспечена всем необходимым, а заказчик понимал, на каком этапе находится работа.
Product Manager отвечает за развитие продукта. Он изучает потребности пользователей, определяет приоритеты и помогает команде создавать функции, которые действительно приносят пользу.
Engineering Manager или Head of Engineering больше внимания уделяет развитию людей и команды. Он помогает специалистам расти
