Peer-to-Peer Load Balancing
Explore peer-to-peer load balancing in Node.js to distribute client requests directly to multiple servers. Understand how this pattern reduces infrastructure complexity, improves performance, and avoids single points of failure by enabling smarter clients that implement load balancing algorithms. Gain practical knowledge by implementing an HTTP client with a load-balancing mechanism using Node.js, enhancing scalability within internal networks.
We'll cover the following...
Using a reverse proxy is almost a necessity when we want to expose a complex internal network architecture to a public network such as the Internet. It helps hide the complexity, providing a single access point that external applications can easily use and rely on. However, if we need to scale a service that’s for internal use only, we can have much more flexibility and control.
Let’s imagine having a service, Service A, that relies on Service B to implement its functionality. Service B is scaled across multiple machines and it’s available only in the internal network. What we’ve learned so far is that Service A will connect to Service B using a load balancer, which will distribute the traffic to all the servers implementing Service B. ...
