A cluster is the grouping of two or multiple physical servers that are perceived to the network as one network server, Services and applications in the cluster are called resources.

Server clusters connect several dedicated servers, providing more cost-efficient ways to achieve higher levels of performance and availability. Chat with an expert today about how we can address your challenges with a clustered hosting solution that’s tailored to your needs and your budget. Load balancing shares traffic between servers, increasing capacity, improving server performance and providing redundancy with failover in the event of hardware or application failure.

Let’s say we now have three web servers. Incoming requests are spread across the servers. Choosing which server to send a specific request to is complex and there are lots of ways of organizing it, but for simplicity’s sake think about sending the requests to each server in turn. Every new request is sent to the next web server. To decide which web server will receive each response, you use a load balancer. Load balancers sit in front of the web servers and send the requests on to them. Because there is now far more web server capacity, every request can be dealt with in a timely fashion.

There are three main reasons for server clustering. They are availability, scalability and reliability. The key to a protected IT infrastructure lies in redundancy. Creating a cluster of servers on a single network offers the ultimate redundancy and ensures that a single error doesn’t shut down your entire network, render your services inaccessible and cost your business vital revenue. Speak with a customer service representative at a local web-hosting provider to learn more about the benefits of clusters and how to get started.Load balancing is a strategy aimed at achieving even distribution of user sessions across Intelligence Servers, so that no single machine is overwhelmed.
