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

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

The Bulkhead Pattern isolates resources to protect critical workloads from failures.

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

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

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

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

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

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

Fallbacks allow systems to handle failures safely and maintain user experience.

Request-Response asks for a result, while Events notify that something has happened.

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

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.

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

A Circuit Breaker helps prevent system failures by stopping calls to unhealthy services.
