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

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

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.

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

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.

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

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.

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

RPC allows one service to call a function in another service over the network.

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.

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

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

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.
