IBM and VMware are the vendors most dedicated to creating private clouds, analysis of developer surveys shows.
Microsoft has established the Azure platform and succeeded in recruiting developers to it, but even so "it lags behind Sun, HP and Citrix in eliciting confidence from developers in its offerings," Garvin concluded.
The ratings for confidence in IBM among developers indicates it's "apparently been highly successful in getting its story out and convincing [developers] of their relative strength in providing cloud services."
The conclusion is firmer than IBM's performance to date might seem to warrant. Top IBM cloud spokesmen, such as VP Willy Chiu and Kristof Kloeckner, CTO of cloud computing, say the availability of key IBM technologies for the cloud are still to come, such as a set of Rational development tools geared to work in the cloud. Nevertheless, Garvin concludes, developer enthusiasm "presents a very positive outlook for IMB in the world of cloud services."
The report then turned its attention to vendors "at the back of the pack," including AT&T, CA, Aptana, Rackspace, HP, Citrix, and Sun.
A year ago, AT&T launched its Synaptic Hosting managed infrastructure service, which includes pay-as-you-go access to servers, storage, security and networking. "AT&T's physical infrastructure gives it an advantage in the long run, but… it is new player in the world of software platforms," Garvin noted.
CA is focused on the private cloud for the enterprise "with little outreach to developers." It shows up as a player on the Evans Data chart summarizing the results of its cloud research and is ahead of AT&T and Rackspace in terms of ability to execute but behind them and everyone else in terms of completeness of its cloud offerings.
Rackspace is a well known server hosting service, Garvin continued, that is now offering cloud services. "Rackspace seems well positioned to capture a share of the market with its hosting prowess" but still needs to get the word out that it can offer more cloud-oriented services, she wrote.
HP gained middle of the pack ratings on most issues, which is explained by the fact that HP "has an arms-length approach to developers, preferring to work through partners," Garvin said.
Citrix ranked as a contender as a supplier to the private cloud due to its virtualization product line based on XenServer but Garvin noted the firm is "not necessarily known for cloud hosting."
