Verify with: docker --version Step 1 — Clone the Repository https://github.com/ossyzali/spring-petclinic-microservices.git Step 2 — Start Everything with One Command Step 3 — The Startup Order and Why It Matters Step 4 — Verify the Applica
Most API testing tutorials test a single endpoint in isolation. Real systems are messier: services call each other over HTTP, share JWT tokens, and fail in ways that only show up when the whole thing runs together. This article takes a different approach. We will build a small but realistic microser
In one line: deduplication is about the evidence that a side effect has been applied — make it atomic with the effect, visible to everyone, and tied to a unique identifier. This is just how I think it out — not a tutorial, not the final answer. I'm sharing my reasoning, and I'd love to hear where it
There's a headline pattern that feels like sharp marketing writing but quietly costs conversions. "You code. We cloud." It's clever. The parallel structure is tight. It names a clear division of labor. But it describes the service delivery model, not the developer outcome — and those are different t
In 2017 I was maintaining a Node.js ecommerce server when a new project landed on my desk — an IoT platform for vehicle tracking devices. Thousands of devices, transmitting data continuously, with clients expecting real-time visibility into what the devices were reporting. The Node.js server started
The Logging Nightmare Deploying microservices across Multi-Cloud environments using tools like Terraform is an exhilarating milestone. But the moment something breaks, that excitement quickly turns into a nightmare. The SSH Grind: If you find yourself SSH-ing into disparate instances just to run tai
If you have worked on a long-lived product, you probably know this feeling: "We can still ship, but every release hurts more than the last one." That is usually not a team problem. It is a core architecture problem. At some point, modernization stops being a nice-to-have refactor and becomes a survi
Microservices architecture has evolved from a buzzword to a fundamental paradigm for building distributed systems at scale. The core premise is straightforward: decompose your application into independently deployable services that communicate over the network, each owning its own data domain and bu
