What Is SRE?
Imagine you are using your favorite messaging app to chat with friends. Suddenly, messages stop sending or the app crashes. Now, think about shopping online during a big sale and the website goes down just as you're about to check out. These moments show how much you rely on digital services to work smoothly every time you use them.
What is Site Reliability Engineering (SRE)?
Site Reliability Engineering, or SRE, is a discipline that helps organizations build and run reliable, scalable software systems. SRE blends software engineering with IT operations, focusing on automating tasks, improving system reliability, and ensuring smooth user experiences.
The concept of SRE started at Google in the early 2000s. Google's leaders asked a team of software engineers to make their massive websites and services more reliable. Instead of relying only on traditional IT operations, these engineers used their programming skills to automate manual work and solve reliability problems with code.
SRE bridges the gap between software development and IT operations. In many companies, developers write code and hand it off to operations teams, who are responsible for keeping everything running. This handoff can lead to misunderstandings and delays. SREs work closely with both teams, using software engineering practices to automate processes and prevent problems before they affect users.
Real-Life Example
Imagine you use an online shopping site. When you click "Buy Now," you expect the site to process your order quickly and accurately, even during a big holiday sale. SREs ensure the site stays up, performs well, and recovers quickly if something goes wrong. If a sudden spike in traffic causes slowdowns, SREs might have built automatic systems that add more servers or fix issues without human intervention.
By combining software engineering and operations, SREs help companies deliver reliable products that users can trust, even under pressure.
