Redundancy and Persistence: Building Resilient Applications

Architecture Corner Newsletter Podcast - Application availability isn't just about uptime percentages; it's about designing systems that gracefully handle failure through strategic redundancy and data persistence patterns. In this episode we will cover: Redundancy fundamentals - How load balancers and reverse proxies distribute traffic across multiple instances and the challenges of maintaining consistent behavior across replicas Stateless vs stateful considerations - Why stateless services simplify redundancy and the complications that arise with session-dependent applications Persistence synchronization strategies - The trade-offs between synchronous and asynchronous data replication, including potential data loss and consistency challenges AWS managed solutions - Real-world examples from RDS, Aurora, and DynamoDB showcasing different approaches to multi-AZ redundancy and their availability guarantees The consistency spectrum - Understanding eventual consistency versus strong consistency and when to choose each approach for read operations For more details check ⁠here⁠.
