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

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

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

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

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

Timeouts in distributed systems indicate suspicion, not confirmed failure.

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

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

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

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

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

Cascading failures occur when one service's failure impacts others, causing widespread issues.

Synchronous communication waits for a response, while asynchronous continues without waiting.

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

A reverse proxy routes client requests to different backend services efficiently.

Partial failure means some services fail while others keep running, impacting system reliability.

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

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

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