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

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

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

Distributed caching spreads data across multiple servers for better performance and reliability.

The CAP Theorem explains the trade-offs in distributed systems during network failures.

Availability is about access; reliability is about correct performance.

2-Phase Commit helps maintain data consistency in transactions across multiple databases.

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

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

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

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

Caching helps applications respond faster by serving data from memory instead of hitting the database.

Cache breakdowns can overwhelm databases, but request coalescing solves this issue.

HTTPS is a secure version of HTTP that encrypts data for safety.

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

Latency is the time for one request, while throughput is how many requests are processed.

Dependency failures can disrupt applications, but resilience patterns can help manage them.

DNS helps microservices find each other, but it has limitations that may require a service registry.

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

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

DNS resolution translates a URL into an IP address for web access.

Kafka uses state stores to remember previous events in stateful stream processing.

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