P.01When something produces work faster than something else can handle it, the system has to do one of three things: buffer, drop, or push back. Here's how backpressure actually works across queues, streams, and APIs, with real implementation patterns.
P.02Integration tests that spin up every dependent service are slow and flaky. Contract testing checks that a consumer and provider agree on a shape without either one running, and catches the breaking changes end-to-end tests miss. Here's how to set it up with Pact.
P.03A message that fails every time it's retried shouldn't loop forever or vanish silently. Here's how dead letter queues catch it, how to configure retry limits properly, and the reprocessing workflow that actually closes the loop.
P.04Queues, pub/sub, and event streaming all move messages between services, but they answer different questions about delivery, replay, and who's allowed to read what. Here's the decision framework and where each one breaks down.
P.05Writing to your database and publishing an event are two separate operations, and a crash between them silently loses data. The transactional outbox pattern closes that gap. Here's how it works and how to implement it.
P.06A single GraphQL schema works until multiple teams own different parts of your data. Here's what federation actually solves, how Apollo Federation composes subgraphs, and when the added complexity is worth it.
P.07When a business transaction spans multiple services, you can't wrap it in one database transaction anymore. The saga pattern solves this with a chain of local transactions and compensating actions. Here's how it works and when it earns its complexity.
P.08Service meshes promise secure, observable microservice communication. But most teams that adopt one do so before they need it. Here is how to decide, and what each option actually costs you.
P.09Everyone says go cloud-native. But what does that actually mean in 2026? We break down microservices, serverless, and containers — and why most teams should start simpler than they think.
