Many companies are sold on the idea that virtual servers are going to be cheaper than their current physical versions because they will consume less local power, take up less actual space and provider a multiplicity of instances on which their applications can run. As each VPS represents its own tiny universe where applications can run unhindered by any others on the system, companies often assume that this gives them more control of their data. But while the applications themselves may be easier to manage individually, once the number of instances on a virtual server pushes up past 20, problems in management begin to arise.
One instance of the VPS being out of sync with the virtual guidelines can lead to a greater cost to manage than a set of physical servers, and as a result a number of VPS providers are beginning to bundle automated tool sets with their server packages in order to allow companies to both control and streamline their virtual data use. As the use of virtual servers continues to increase in 2011, businesses will find themselves relying more heavily on technology to automatically monitor remote servers, and the level of functionality of this technology will in many ways define which provider is crowned the king of the virtual server hill.
For some companies, the time to make the switch to a virtualized has not yet arrived; the costs still outweigh the benefits. But for those that find themselves in a multiple VPS instancing situation, it is key that these servers not only be properly partitioned, monitored, and secure but that they have a level of management which does not let their virtual data become as cluttered as it did on the physical servers it left behind.
