Design Microservices Architecture with Patterns and Principles - Bulkhead Pattern

The bulkhead pattern is a design strategy used in distributed systems to isolate failures and prevent them from affecting the entire system. Inspired by naval architecture, it involves isolating service instances to manage high loads and unresponsive services. The pattern can be implemented by setting resource limits, such as in Kubernetes. A real-world example is an e-commerce application where the pattern isolates services like payment processing to ensure other services continue functioning. The bulkhead pattern is useful in scenarios with high load, resource contention, or dependency on unreliable services.

What are the resource limits that can be defined for implementing the bulkhead pattern?

Explain how the bulkhead design pattern can be implemented in an e-commerce application.
