Why Anti-patterns (distributed monolith, chatty services) in Microservices? - Purpose & Use Cases

The Big Idea

What if your 'microservices' were actually just a slow, tangled mess in disguise?

The Scenario

Imagine a team building a big app by splitting it into many small parts, but these parts keep calling each other too much, like a group of friends who can't stop texting back and forth every minute.

The Problem

This constant back-and-forth slows everything down, causes confusion, and makes fixing problems a nightmare because changing one part breaks many others unexpectedly.

The Solution

Recognizing these anti-patterns helps teams design services that work independently and communicate efficiently, avoiding tangled dependencies and slowdowns.

Before vs After

✗ Before

serviceA calls serviceB for data, then serviceB calls serviceC, then serviceC calls serviceA again

✓ After

serviceA handles its own data or calls serviceB once with all needed info, minimizing calls

What It Enables

It enables building fast, reliable systems where each part can evolve without breaking the whole.

Real Life Example

A shopping app where the payment service doesn't need to ask the inventory service every second, but gets all info upfront, making checkout smooth and quick.

Key Takeaways

Too many small services talking too much cause delays and bugs.

Distributed monoliths hide tight coupling behind service boundaries.

Good design means clear, minimal communication between independent parts.
