🌟 Polling and long-polling vs WebSockets vs Server-Sent Events (SSE)🌟
🔶WebSockets: Provides a persistent, full-duplex connection between the client and server.
🔶Server-Sent Events (SSE): Allows servers to push updates to the client over a single HTTP connection.
🔶Polling: Polling is a technique where the client regularly sends requests to the server to check for updates or new data.
🔶Long-Polling: Long-polling is an enhanced version of polling designed to reduce latency and resource usage. It keeps a connection open until the server has new information to send.
Client-server communication is a fundamental aspect of networked applications where two main entities are involved: the client and the server.
Understanding client-server communication is important for designing and implementing effective and efficient network applications like flight booking applications EaseMyTrip.com, Booking.com and stock market applications 5paisa, Upstox).
🌟 Here's an overview of how it works 🤔
🔶Client: The client is a device or application that requests services or resources from a server. This can be a web browser, mobile app, or any other networked software.
🔶Server: The server is a system that provides services, resources, or data to the clients. It listens for incoming requests, processes them, and sends back the appropriate responses.
🌟 Several protocols facilitate client-server communication:🌟
🔶HTTP/HTTPS: Used for web communications. HTTPS is the secure version of HTTP.
🔶WebSocket: Provides full-duplex communication channels over a single TCP connection, allowing real-time data exchange.
🔶REST: An architectural style using HTTP requests to access and manipulate data, often in JSON or XML format.
Security Considerations
🔶Encryption: Using HTTPS ensures that data exchanged between the client and server is encrypted.
🔶Authentication and Authorization: Ensures that only authorized clients can access certain resources or services.
🔶Data Validation: Servers should validate incoming data to prevent attacks like SQL injection or cross-site scripting (XSS).
🌟 Performance Optimization🌟
🔶Caching: Storing frequently accessed data closer to the client to reduce server load and improve response times.
🔶Load Balancing: Distributing incoming requests across multiple servers to ensure no single server is overwhelmed.
🔶Compression: Compressing data before sending it over the network to reduce bandwidth usage.
🌟 WebSockets for real-time updates can maintain a persistent connection, allowing for instant communication between the client and server, which can be especially beneficial for real-time applications like booking systems where updates need to be as immediate as possible.
