Monolithic and microservices architectures each have unique advantages and challenges for software development.

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

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

An API Gateway simplifies client access to backend services in microservices.

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

Microservices and modular monoliths differ mainly in deployment and communication methods.

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

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

The Saga Pattern manages distributed transactions using local transactions and compensating actions.

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

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

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

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

Protobuf schema evolution requires careful changes to avoid breaking existing clients.

A timeout indicates a deadline was exceeded, not necessarily a failure.
