How to Build the Worst Microservices System Ever

⚡️Microservices are often implemented to decrease coupling and increase deployability, but let's be honest, we do it for the complexity and decreased performance.

🔥Applying the Strangler fig pattern can help in transitioning from a monolith to microservices, but if applied everywhere, it can result in decreased throughput and increased latency.

💀.NET's garbage collection process can have a significant impact on system performance, especially in a microservices architecture with multiple network hops.

🌐Network operations introduce latency and can impact the scalability of a microservices system, leading to diminished throughput as the load increases.

👹Building a terrible microservices system requires embracing complexity, convoluted implementations, and avoiding monoliths just for the sake of it.

Why do we implement microservices?

—While the official answer is to decrease coupling and increase deployability, let's be honest, we do it for the complexity and decreased performance.

What is the Strangler fig pattern?

—The Strangler fig pattern is a technique used to transition from a monolith to microservices. It involves isolating a piece of functionality and moving it to a separate service while the monolith still calls the new service.

How does garbage collection affect microservices?

—.NET's garbage collection process can lead to increased latency in a microservices system, especially with multiple network hops, as garbage collection events can pause all user threads.

How do network operations impact microservices?

—Network operations introduce additional latency and can impact the scalability of a microservices system, leading to decreased throughput and increased response times as the load increases.

Should we avoid monolithic architectures?

—Monoliths aren't inherently bad. It's important to evaluate the specific requirements of a project and choose the appropriate architecture, rather than blindly following the microservices trend.
