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

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

HTTP methods tell the server what to do, and status codes tell us the result.

Timeouts in distributed systems indicate suspicion, not confirmed failure.

Vertical scaling means upgrading one server, while horizontal scaling means adding more servers.

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

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

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

Search engines collect, index, retrieve, and rank documents to provide relevant results.

The TCP 3-way handshake ensures reliable connection establishment between a client and server.

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

The TLS handshake establishes a secure connection for HTTPS, ensuring data safety.

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

Distributed locks ensure only one server performs a task, avoiding duplication.

Network partitions occur when servers are operational but can't communicate, affecting system performance.

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

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

REST API design focuses on creating clean, efficient, and scalable web services.
