FAANG engineers use high-level design principles to create scalable systems.

Service Discovery helps microservices locate each other dynamically without fixed IP addresses.

Choosing the right boundaries for microservices is crucial for effective architecture.

RPC allows one service to call a function in another service over the network.

Database per Service ensures each microservice owns its data, reducing dependencies.

Microservices are useful when you need independent scaling, deployment, and clear boundaries in software design.

Distributed backpressure helps manage the flow of work between services to prevent overload.

gRPC supports four communication patterns: Unary, Server Streaming, Client Streaming, and Bidirectional Streaming.

Microservices can communicate using five key patterns based on their needs.

DNS helps microservices find each other, but it has limitations that may require a service registry.

Choosing between a shared database and a database per service affects system design significantly.
