In today’s connected world, APIs are the backbone of modern applications. But with growing user bases and interconnected services, the risk of server overload, abuse, or system crashes becomes real. That’s where rate limiting and throttling step in — to ensure performance , security , and fair usage . What Is API Rate Limiting? API rate limiting controls how many requests a client can make to an API within a specific time frame . It helps prevent abuse (like DDoS attacks), ensures fair access among users, and safeguards infrastructure from being overwhelmed. Example: A public API may allow 1000 requests per hour per user. After that, users receive a 429 Too Many Requests error until the limit resets. What Is API Throttling? Throttling is a dynamic form of rate limiting. Instead of outright rejecting requests, it slows down or queues them when usage exceeds safe thresholds. It ensures graceful degradation rather than abrupt denial.

  In today’s hyper-connected world, users expect real-time interactions—whether it's chatting with support, receiving stock updates, or tracking delivery in motion. Traditional HTTP was never built for this level of immediacy. Enter WebSockets —the game-changer for real-time, two-way communication between clients and servers. What are WebSockets? WebSockets are a protocol that enables persistent, full-duplex communication between the client and the server over a single TCP connection. Unlike HTTP, which is request-response based, WebSockets allow data to flow freely both ways without repeatedly opening new connections. How WebSockets Work Handshake : It starts with an HTTP request to initiate the WebSocket connection. Upgrade : If the server accepts, the protocol switches from HTTP to WebSocket. Persistent Connection : Once established, both the client and server can send data at any time. WebSockets vs. HTTP Polling Use Cases of WebSockets...
