Server clusters

A server cluster uses several dedicated servers to do several different jobs, or to share the burden of one important task. Add as many servers as you need to maintain your preferred performance level.

A very common server cluster configuration is a web server cluster (or web cluster), which spreads Internet traffic over several web servers using load balancing. This creates a high-availability server with increased capacity and failover.

iWeb can tailor a web cluster to your exact requirements, or you can quickly achieve a high-availability web server with the starter web cluster package outlined below.

iWeb’s web cluster package is perfect for both Linux and Windows hosting. The Linux web cluster supports Apache, PHP and Perl, while the Windows web cluster supports IIS, ASP and .Net. The cluster can also be customized to support a wide range of additional software. If you have a specific requirement, get in touch.

Data replication

As part of the web cluster package our experts will install and configure data replication scripts to ensure that content is always synchronized between your web servers. We can also design a storage solution that eliminates the need for data replication by using single storage server.

Benefits of the Web Cluster

Keep your web sites available all the time
High-availability web server

The web cluster uses load balancing to send your visitors’ requests to available servers. If a server fails, it is automatically removed from the available servers pool and your visitors are sent to servers capable of serving your website.

Scale and increase capacity when you need it
Scale and increase capacity when you need it

There’s no need to fear being featured on the biggest websites. With a web cluster you’re ready to receive a storm of visitors. Upgrade from two to tens of servers in a matter of hours, whenever you need to. Install your web cluster in a private dedicated server rack and you’re ready to scale to hundreds of servers.

Improved performance
Improved performance

By sharing your web applications’ load between multiple servers, you decrease the amount of resources needed by each server and improve the performance for your end users. Add as many servers as you need to maintain your preferred performance level.

Enhanced Security
Enhanced Security

In addition to using your own dedicated private switch, your web servers are installed behind a load balancer that can also act as firewall allowing only the right traffic to reach your web servers. Like a firewall, the load balancer can be configured with rules to your specifications.
