Site Reliability Engineering (SRE) is a systematic and data-driven approach to improving the reliability, scalability, and efficiency of systems. It combines principles of software engineering, operations, and quality assurance to ensure that systems meet performance goals and business objectives. This article discusses the key elements of SRE, including reliability goals and objectives, reliability testing, workload modeling, chaos engineering, and infrastructure readiness testing.

Inconsistent data and GTIDs with mysqldump Marcelo Altmann (Senior Software Engineer) fixed the bug when data and GTIDs backed up by mysqldump were inconsistent. It happened when the options –single-transaction and –set-gtid-purged=ON were both used because GTIDs on the server could have already increased between the start of the transaction by mysqldum

For example, imagine a simple e-commerce application that includes a mobile app, web server, and database. If a user reports that the app is freezing while attempting to make a purchase, it can be challenging to determine the root cause of the problem.

The Southwest Airlines fiasco from December 2022 and the FAA Notam database fiasco from January 2023 had one thing in common: their respective root causes were mired in technical debt. At its most basic, technical debt represents some kind of technology mess that someone has to clean up. In many cases, technical debt results from poorly written code, but more often than not, it is more a result of evolving requirements that older software simply cannot keep up with.

White box testing is a software testing approach based on an analysis of the internal structure of the component or system. Internal structure may include code, architecture, integrations, and data flows of a system. Why is White Box Testing Performed? Testers perform white box testing for several reasons. The main reason to include it in your test plan is that it provides much more test coverage than black box testing alone.

A food delivery app is a mobile application that allows users to order food online from their favorite restaurants and have it delivered to their doorstep. These apps typically offer a wide range of cuisine options from local restaurants and fast-food chains, and allow users to browse menus, place orders, and pay online. Once the order is placed, the app notifies the restaurant, and the restaurant prepares the food and delivers it to the user’s address.

Effective resource management is essential to ensure that no single client or task monopolizes resources and causes performance issues for others. Shuffle-sharding is a valuable technique to achieve this. By dividing resources into equal segments and periodically shuffling them, shuffle-sharding can distribute resources evenly and prevent any client or task from relying on a specific segment for too long.
