Site Reliability Engineering (SRE) Explained: Complete Beginner’s Guide to Google’s Secret to Scalable Systems What is Site Reliability Engineering (SRE)? Site Reliability Engineering (SRE) is a discipline that combines software engineering and IT operations to ensure high availability, performance, and scalability of systems. It was first developed by Google to keep their massive systems reliable and automated. In simple terms: SRE = Software Engineering + Infrastructure/Operations Why SRE is Important? Downtime = Loss of Users + Revenue 💸 SRE teams make sure your app stays up, fast, and reliable . They write code to automate ops tasks and reduce manual errors. 🔹 Core Principles of SRE SLI, SLO, SLA SLI (Service Level Indicator): What to measure (e.g. uptime, latency) SLO (Objective): Your goal (e.g. 99.9% uptime) SLA (Agreement): What you promise customers (often with penalties) Error Budget Acceptable level of failure (e.g., 0.1% downtime per m...

  AWS (Amazon Web Services) is a powerful cloud computing platform that offers a range of services for businesses and individuals. To make the most of AWS, it's important to understand the key terminology used in the platform. In this blog, we'll take a look at some of the most important AWS terms and what they mean.

  Continuous Integration (CI) and Continuous Deployment (CD) are two of the most important processes in software development. CI helps to identify and fix errors in the early stages of the development process, and CD automates the deployment of the software to production. Both Bamboo and Jenkins are two of the most popular CI/CD tools available in the market. In this blog, we will compare Bamboo vs Jenkins with an example and see which one is better suited for your needs. Bamboo Bamboo is a CI/CD tool developed by Atlassian, the same company behind popular tools like JIRA and Confluence. Bamboo is a paid tool, but it offers a lot of features that make it worth the investment. Bamboo integrates seamlessly with other Atlassian tools and provides a wide range of features like: Build agents: Bamboo supports remote and local build agents to execute builds, which can run on any platform. Build triggers: Bamboo supports various build triggers like changes in code repository, schedule buil...
