The first time I decomposed a monolith into microservices, I made every mistake in the book. We ended up with a distributed monolith—all the complexity of microservices with none of the benefits. That painful experience taught me that microservices architecture isn’t about the services themselves; it’s about the patterns that make them work together. Microservices… Continue reading

The Serverless Revolution: Why AWS Lambda Changed Everything I Thought I Knew About Building Scalable Systems
There’s a moment in every architect’s career when a technology fundamentally rewrites your mental model of how systems should work. For me, that moment came in 2016 when I deployed my first AWS Lambda function and watched it scale from zero to handling thousands of concurrent requests without a single configuration change. After two decades… Continue reading
Event-Driven Architecture on GCP: Mastering Cloud Pub/Sub for Real-Time Systems
Introduction: Google Cloud Pub/Sub provides the foundation for event-driven architectures at any scale, offering globally distributed messaging with exactly-once delivery semantics and sub-second latency. This comprehensive guide explores Pub/Sub’s enterprise capabilities, from dead letter queues and message ordering to BigQuery subscriptions and schema enforcement. After building event-driven systems across multiple cloud platforms, I’ve found Pub/Sub… Continue reading
The Serverless Revolution: Why AWS Lambda Changed How We Think About Infrastructure
When AWS Lambda launched in 2014, it fundamentally changed how we think about infrastructure. No servers to provision, no capacity to plan, no patches to apply—just code that runs when triggered. After building distributed systems for over two decades, I’ve witnessed many paradigm shifts, but serverless computing represents one of the most significant changes in… Continue reading
Azure Functions and Serverless Architecture: A Solutions Architect’s Guide to Event-Driven Computing
After two decades of building enterprise applications, I’ve witnessed the evolution from monolithic deployments to microservices, and now to serverless architectures. Azure Functions represents a fundamental shift in how we think about compute—moving from “always-on” infrastructure to truly event-driven, pay-per-execution models. This transformation isn’t just about cost savings; it’s about building systems that scale automatically… Continue reading
