#loadbalancer :
Overview: A Load Balancer acts as a traffic cop, distributing incoming network requests across multiple servers to ensure no single server is overwhelmed. This not only optimizes resource utilization but also enhances the scalability and reliability of web applications.
How it Works: Load Balancers use algorithms to distribute incoming requests among a pool of servers. This distribution can be based on factors like server response time, server load, or a round-robin approach. The primary goal is to prevent any single server from becoming a bottleneck and to ensure even distribution of incoming traffic.
Use Cases:
High Traffic Websites: Load Balancers are essential for popular websites that experience high levels of traffic. Distributing requests across multiple servers prevents performance degradation and downtime.
Scalable Applications: In cloud environments, Load Balancers facilitate the automatic scaling of applications. As the demand for resources increases, additional servers can be added to the pool, and the Load Balancer efficiently distributes the load.
#ReverseProxy:
Overview: A Reverse Proxy serves as an intermediary between client devices and web servers. It receives requests from clients on behalf of the servers, acting as a gateway to handle tasks such as load balancing, SSL termination, and caching.
How it Works: When a client sends a request, it is first intercepted by the Reverse Proxy. The Reverse Proxy then forwards the request to the appropriate server, retrieves the response, and sends it back to the client. This process hides the identity and characteristics of the servers from clients.
Use Cases:
Security and Anonymity: Reverse Proxies enhance security by masking the internal server infrastructure. They provide an additional layer of defense against malicious attacks, as attackers interact with the proxy rather than the actual servers.
SSL Termination: Reverse Proxies can handle SSL/TLS encryption and decryption, offloading this computationally intensive task from web servers. This improves overall server performance and simplifies SSL certificate management.
#ForwardProxy:
Overview: A Forward Proxy, also known simply as a proxy, acts as an intermediary between client devices and the internet. It facilitates requests from clients to external servers, providing functionalities such as content filtering, access control.
How it Works: When a client sends a request to access a website, the request is first intercepted by the Forward Proxy. The proxy then forwards the request to the destination server, retrieves the response, and sends it back to the client.
Use Cases:
Content Filtering: Organizations use Forward Proxies to control and monitor internet usage within their network. Proxies can filter out malicious content, restrict access to certain websites, and enforce usage policies.
