The Need for Creating a Proper Virtual Server Setup
When you have outgrown a shared hosting service signing up for a virtual server is an easy decision to make. A web hosting company also usually offers a VPS service which you can avail as an upgrade. This can be a big step, as a VPS requires more work than a shared hosting service. As a computer in its own right, a virtual machine has to be configured according to your requirements. A virtual server setup works almost the same as a setup for a physical server except for some slight differences.
Making use of Multiple Virtual Server Setup
When you avail of a VPS service, you have complete control over the virtual dedicated server. This means that you can install any software that you want. You can also configure a virtual machine for load balancing or for a clustered application. The virtual server setup can take this into account and have all the software installed and working properly. The VPS provider would be able to assist accordingly. In addition, they would be more than happy to provide you with more virtual servers.
A web hosting company provides not only internet servers, but also dedicated servers for remote operations or other remote computational need. These can be in the form of dedicated hosting or VPS services. With a VPS, the assistance with the virtual server setup can be provided by the web hosting company. The services include not only setting up the software for virtual machine, but also any software which would reside in the server, as well as support and maintenance for associated software which resides in the virtual machine container.
Planning for Multiple Virtual Machines Cluster
When planning your virtual server setup, you have to keep in mind the specifications of the virtual servers, your expected volume of traffic, and your storage capacity. For the purposes of web hosting or a remote server, the virtual machines have to function in the same way as real physical machines. The performance might be a little slower but it should not be significantly nor noticeably different. This means that you can plan for multiple servers serving files or data for an ecommerce site, or a high volume traffic site. Multiple servers can also be used for a company intranet or remote backup server. The same planning for multiple computers on a cluster can enable a relatively high availability server capability.
There are a lot of ways a multiple server setup can help a website. An ecommerce site can have a server for the customer database, a separate server for the product database, and still another server for pictures and images besides those of their products. An ad server can have the image database distributed over several virtual machines. The cluster configuration can be for a file cluster or a server cluster setup. This solution uses multiple machines accessing a large database, as if it was only on server. A virtual server can be used to load balance the requests across the clustered database server.
Proper setup is necessary in order to make sure that the resources are properly used. Creating a wrong setup for multiple servers would result in heavy traffic for a few servers while others would be idle. This would overwork some machines and lead in bottlenecks in serving browser requests. Such an occurrence would render the multiple server setup useless.
