The Truth about Cloud Performance

truth about cloud computingCloud computing vendors will tell you that one of the biggest benefits to the cloud is increased performance. Indeed, some cloud solutions do provide a more robust user experience than an in-house app. The big picture, however, isn’t quite as clear. Public cloud services can be very powerful and highly functional, but there are also some potential performance hits.

Cloud solutions are, by their very nature, multitenant. That means you’re going to have more than one user, process, or machine accessing the app at a time. When that happens, those virtual and physical resources are being used. While the systems can be very effective and minimize the impact of other users on a single process, you can more often than not tell when use is heavy.

A variable situation

Because of the multitenant nature of the cloud, performance profiles are going to be variable based on what’s happening in that cloud at any given time. If you peek inside a cloud provider’s logs and look at various metrics such as I/O, you’ll begin to see patterns that are rather sporadic. The fact of the matter is that a single organization using a single application tends to have peak times; when you have twenty organizations using an application in a cloud, those peak times can be all over the board.

What’s more, in an internal environment, you can prepare for known anomalies such as month-end reports on an accounting system. Cloud solutions are likely to get hit harder by these types of occurrences.

A flexible and agile solution

The good news is that cloud solutions are agile. You can start up additional instances of the individual resources that you need. As long as the provider is on their game, you may only experience performance degradation for a short time while they bring additional resources on line to meet their customers’ demands.

Ultimately, the performance of any given cloud solution comes down to two factors: the system’s design, and the ability of the system managers to make adjustments based on demand. These are the key elements you need to look at when choosing a cloud provider.
