State of the Cloud – October 2009

State of the Cloud – October 2009

With each new month comes a new State of the Cloud post. In case you have joined recently, State of the Cloud is a regular report on the adoption of cloud infrastructures, comparing the market share held by each provider. As always, please refer to the first post in the series for methodology, data sets and caveats.

Today I’m glad to be adding OpSource as the fifth provider compared in the report.  Originally, UK-based providers FlexiScale and ElasticHosts were planned for inclusion. However, the US-oriented nature of QuantCast’s rankings resulted in underrepresentation of their customer base (recall that QuantCast’s top site list is the data set for this research). At this point, they will be omitted from the report.

Snapshot for October 2009

No big surprises for us this month. Amazon EC2 continues to lead the pack with Rackspace Cloud Servers closely behind. Newcomer OpSource enters into fifth place with 19 hits from the sites sampled.

Monthly Growth

Last month, it was Amazon EC2 that outpaced the rest of the providers. This month, it was Rackspace which exhibited the fastest growth,  with over 10% since last month!


With more and more data to track, the major trends are beginning to take shape. The primary contenders continue to be Amazon EC2 and Rackspace Cloud Servers. It will no doubt be interesting to watch how the battle for the top spot unfolds over the coming months.
