As companies turn to the Cloud as a low cost, highly scalable and agile way to save on their infrastructure cost or to host new applications, a number of cloud performance testing and monitoring solutions are appearing. There are applications popping up to perform load testing against your cloud infrastructure, some of which are even developed and hosted by the providers themselves, such as Grinder in the Cloud and Pylot, as well as a number of commercial services.
While these tools are needed and can be quite valuable, they all miss the most critical aspect of cloud performance: the physical distance between your users and the cloud infrastructure.
The majority of applications that are run from the Cloud are running on top of TCP and because TCP is location dependent, the physical distance between your users and the Cloud Datacenter has a dramatic impact on the maximum achievable performance you will see from the cloud. As this example details the latency on a network connection can be a bigger factor in the end to end performance, so much so that a 1 Gbps WAN connection from New York to Chicago with latency of 30ms has a maximum achievable throughput of 17.4 Mbps. That distance between New York and Chicago just cost you 98% of the capacity you are paying for. Finding out where the Cloud Data Centers are should be one of the critical questions to be answered before signing on with any Cloud Provider.
There is now a way to see the performance to each of these cloud providers both in terms of the maximum achievable performance as well as the performance to major cities around North America. The Cloud Performance Center measures the performance from 10 major cities to leading Cloud Providers. The Cloud Performance Center provides real-time performance information including the Total and Available bandwidth, Latency, Packet Loss and Round Trip Time. All of this information is available free, and you can subscribe to be notified of performance issues in any provider you are interested in.
The low cost and high performance of the Cloud is changing the way IT is delivered, and now you are armed with the info needed to choose the right Cloud provider for you. Check out how your provider is performing at www.cloudperformancecenter.com
