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.

Zero Trust Architecture ensures that no user or device is trusted by default.

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

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

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

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

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

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

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

Timeouts in distributed systems indicate suspicion, not confirmed failure.

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

Structured logging helps in quickly identifying issues by organizing log data consistently.

The RED Method helps monitor microservices using Rate, Errors, and Duration metrics.

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

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