Cloud computing means that businesses, government enterprises and other organizations can run most of their servers online. This reduces costs dramatically, since not only do offices have more floor space for more profitable pursuits, but they also have to spend less acquiring the actual hardware necessary for servers. Servers fill multiple roles in any organization, managing everything from private computer networks and phone lines to backup file storage and remote computing. But just because it's helpful doesn't mean that it's easy.
According to Stephen J. Bigelow, the big issue with most virtual servers is planning. The art of tracking computing resources and habitually checking performance standards is complicated on its own, and actually deciphering server issues from this data is another story entirely. Physical servers make it much easier to track this data, and also gave a clear picture of server resources. Virtual servers, on the other hand, make it easy to allocate resources but much harder to actually get metrics on how they are performing.
Typically, the problem is best solved with experience. The hardware or software involved with the servers is usually trivial, and replacing them will likely lead to the same situation. On the other hand, a well-versed IT staff can remove idle or redundant virtual servers to free up resources before more servers are installed, and computing capacity becomes more efficient.
Some companies also benefit from server management software that helps plan server capacity. These tools, called virtualization managers, collect server metrics and organize information so that IT staff has a better idea of where resources are allocated, and how to distribute them more effectively.
Poor server capacity can impact a business in several ways, like poorly distributed workloads, performance degradation and poor user experiences. Most of the time, this issue stems from nothing more than a disorganized server state, so having an experienced IT administration is extremely valuable.
