DAZN, a multi-billion dollar sports subscription platform, has implemented various strategies to manage its complex tech stack and achieve 5,000 live releases per day. The company's "reverse pyramid model" allows teams to choose their own products and monitoring tools, adding to the complexity. To address this, DAZN focuses on testing, retrospectives, and standard documentation flow to identify what went well and what didn't. Craig Mclean, Head of SRE, emphasizes the importance of breaking down big problems into manageable chunks, using microservices, and picking small services with limited impact for initial releases. He also stresses the need to measure key metrics, such as performance issues, and generate stress for testing services to ensure they work under stress. By adopting these strategies, DAZN has been able to achieve its goal of 5,000 live releases per day.
