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.

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

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

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

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

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

Message queues allow services to communicate asynchronously, improving scalability and reliability.

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

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

API Gateway, Proxy, and Load Balancer serve different roles in managing requests and traffic in systems.

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

REST, RPC, and gRPC are different methods for communication in software systems.

gRPC allows efficient communication between services using a structured request-response model.
