You can also look at this design pattern as a wrapper around the existing functionality. Let’s dive into the example which will make things much clearer. We have […] System Design tutorial Load Balancing in Distributed Systems Written by Pratyush Jagaty September 6, 2020October 7, 2020 Saving Bookmark this article Bookmarked Load balancing is defined as the methodical and efficient distribution of requests across multiple servers. The load balancer sits between client devices and backend servers, receiving and then distributing incoming requests to a server that is healthy and capable of fulfilling them. A load balancer is a critical component of any distributed system as it helps improve the services offered by increasing availability and responsiveness. As it distributes the traffic across multiple servers, it also helps us avoid a single point of failure. tutorial Consistent Hashing Written by Pratyush Jagaty August 30, 2020October 6, 2020 Saving Bookmark this article Bookmarked Consistent Hashing is a distributed hashing technique that is loosely coupled with the number of servers or objects in a distributed hash table by positioning them in an abstract circle, or hash ring. This allows servers and objects to scale without affecting the overall system.
