Course Wrap-up

Grokking Microservices Design Patterns

Understanding the architecture of the Bulkhead pattern is one thing, but to truly appreciate its power and utility, we need to dive into its inner workings. How does this pattern function in real-time in a running system? How does it handle the inevitable failures that arise in distributed systems? Let's take a closer look.

## Isolation in Practice: Maintaining Independence

In the context of the Bulkhead pattern, the concept of isolation is fundamental. Each bulkhead within the system needs to operate independently of others
