Content Delivery Networks employ reverse proxy technology:
This is my series of an article of CDN, in this article I will talk about how CDN use reverse proxy technology. So let’s start ✍️
Reverse Proxy Server: It is a type of proxy server that typically presents behind a firewall in a private network and a direct client request to the appropriate backend server. It provides an additional level of abstraction and controls to ensure the smooth flow of network traffic between clients and servers.
Content delivery networks employ reverse proxy technology. So we could understand like topology wise, this means CDN is deployed in front of your backend server, Today reverse topology is being leveraged by multi-purpose CDNs to provide the following types of solution.
Web Security:-
Cybersecurity is all about managing outside access to protect your application, ideally blocking all threats before they can even set foot on your application doorstep.
A CDN is perfectly situated to act as a virtual high-security fence and prevent an attack on your website and web application. CDN ideal for blocking DDoS floods, which need to be mitigated outside of your core network infrastructure.
Load Balancing:-
Load Balancing:-It is all about having a “Traffic guard” positioned in front of your servers, alternating the incoming request in such a way that traffic jams are avoided.
Clearly, a CDN’s reverse proxy topology is ideal for this, as it is a default recipient of all incoming traffic. In addition , reverse proxy topology also provides a CDN with enhanced visibility into the traffic flow, this allows it accurately to estimate the amount of pending request on each of the backend servers, thereby load distribution is more effective.
so the next topic of the article is CDN Architecture.
