L4 and L7 load balancers differ in how they route network traffic based on layers of the OSI model.

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

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

Load balancers distribute traffic across multiple servers to enhance performance and reliability.

Availability is about access; reliability is about correct performance.

Stateless servers are easier to scale because they don't store user session data locally.

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

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

Connection pooling reuses database connections but can cause issues if misconfigured.

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

A CDN speeds up web applications by caching content closer to users.

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

Token Bucket allows burst traffic, while Leaky Bucket smooths out traffic flow.

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

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

Jitter helps spread out client retries to avoid traffic spikes.

Queues distribute tasks to one consumer, while Pub/Sub broadcasts events to multiple subscribers.

The USE Method helps find and analyze infrastructure bottlenecks in software systems.

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

Timeouts in distributed systems indicate suspicion, not confirmed failure.
