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

Keep-Alive allows reusing HTTP connections to improve efficiency and reduce overhead.

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

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

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

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

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

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

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

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

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

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

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.

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

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