What is Service Discovery & Heartbeats | Fault Tolerance | Circuit Breaker | Fallback Methods

1. Service Discovery & Heartbeats: Service discovery is a mechanism for automatically detecting and keeping track of services available on a network. Heartbeats are signals sent by a service at regular intervals to indicate that it is still alive and functioning properly. Together, service discovery and heartbeats ensure that applications can dynamically find and communicate with each other in distributed systems.

2. Fault Tolerance: Fault tolerance refers to a system's ability to continue operating properly in the event of failure or errors. It involves designing systems in such a way that they can handle and recover from failures gracefully, minimizing downtime and maintaining overall system reliability.

3. Circuit Breaker: A circuit breaker is a design pattern used in distributed systems to prevent cascading failures. It monitors for failures in remote services and "trips" or interrupts requests to that service if a failure threshold is exceeded. This helps to isolate failing services and prevents them from causing further damage to the system.

4. Fallback Methods: Fallback methods are backup strategies used in software development to handle errors or unexpected situations. When a primary method fails or encounters an error, a fallback method provides an alternative course of action, allowing the system to continue functioning or gracefully degrade its performance.
