In this podcast episode, we explore the imperative of performance in modern cloud-native and microservices architectures, where distributed systems inherently introduce latency and complexity. We'll delve into how architects leverage essential optimization patterns to overcome these challenges, focusing on foundational techniques like caching strategies (Cache-Aside, Read-Through, and Write-Through) to boost read performance and consistency. We'll also unpack Content Delivery Networks (CDNs) for accelerating global content delivery and database sharding for scaling massive datasets, alongside API optimization through the Backend for Frontend (BFF) pattern and efficient asynchronous processing with the Claim Check and Competing Consumers patterns, all crucial for enhancing user experience, optimizing costs, and ensuring scalability.
