Back in 2002, Yahoo acquired Inktomi, a struggling software vendor whose fortunes had turned unpleasantly with the dot-com crash. While at the time of the acquisition, Inktomi had refocused its efforts upon search, its original flagship product — the one that really drove its early revenue growth — was something called Traffic Server.

How much capacity does Amazon EC2 have? And how much gets provisioned?
Given that it’s now clear that there are capacity constraints on EC2 (i.e., periods of time where provisioning errors out due to lack of capacity), this is something that’s of direct concern to users. And for all the cloud-watchers, it’s a fascinating study of [...]

Rackspace has recently launched a community portal called Cloud Tools, showcasing third-party tools that support Rackspace’s cloud compute and storage services. The tools are divided into “featured” and “community”. Featured tools are ones that Rackspace has looked at and believes deserve highlighting; they’re not necessarily commercial projects, but Rackspace does have formal relationships with the [...]

Gartner’s very first Hype Cycle for Cloud Computing features a whole array of cloud-related technologies and services. One of the most interesting things about this hype cycle, I think, is the sheer number of concepts that we believe will hit the plateau of productivity in just [...]

Despite my previous clarifying commentary on the Magic Quadrant for Web Hosting and Cloud Infrastructure Services (On Demand), posted when the MQ was published, and the text of the MQ itself, there continues to be confusion around the positioning of the vendors in the MQ. This is an attempt to clarify, in brief.
This MQ is [...]

Interesting recent news:
Amazon’s revocation of Orwell novels on the Kindle has stirred up some cloud debate. There seems to have been a thread of “will this controversy kill cloud computing”, which you can find in plenty of blogs and press articles. I think that question, in this context, is silly, and am not going to [...]

A recent Forrester survey apparently indicates that that one out of four large companies plan to use an external provider soon, or have already done so. (The Cloud Storage Strategy blog has a good round-up linking to the original report, a summary of the key points, and various commentators.)
Various pundits are apparently surprised by these [...]
