Introduction In distributed systems, consistency is one of the most critical—and misunderstood—architectural decisions you’ll make. Yet many architects and engineers default to strong consistency “because it feels safe,” without understanding the cost in latency, availability, and complexity. The reality is simple: you cannot have everything. The choice of consistency model... [Read More]

Introduction Message brokers are the nervous system of distributed systems. But simply adding a broker to your architecture isn’t enough—you need patterns that ensure reliability, consistency, and scalability. This article explores five critical message broker patterns that every solution architect must understand: transactional outbox, CQRS, CQRS with event sourcing, saga... [Read More]

Introduction The CAP theorem (Brewer’s theorem) is a foundational principle that every solution architect must understand. It defines the fundamental constraints of distributed systems and forces us to make explicit, intentional trade-offs. This article explores CAP in depth, moving beyond superficial interpretations to practical architectural decisions. 1. The CAP Theorem... [Read More]

Inside Java Virtual Threads: Architecture, Scheduling, and Performance Virtual threads (Project Loom) represent a fundamental shift in how Java handles concurrent workloads. Rather than a simple API change, they introduce a new execution model built on continuations and cooperative scheduling. This article explores the internals: what virtual threads are, how...
