VMware's buy of SpringSource has yet to pay off

Two years and $420 million later, it's unclear whether the Spring Framework hit the expected value, but it can still gain traction

But that's unrealized potential. The reality is less glowing. VMware's earning release highlighted the fact that 25,000 developers had signed up for Cloud Foundry. That certainly is a respectable number of interested users in three months since the beta announcement, but it's not uncommon for new products to gain interest when first introduced, only to trail off in the long run. There's some evidence already that most of the "25,000 developers" are just kicking tires: Fewer than 800 users have designated the various Cloud Foundry Git repositories on GitHub as "watched," a proxy for interest level among GitHub users. By contrast, the leading repositories count well over 5,000 watchers.

Of further concern, interest in the Cloud Foundry project targeted at Java applications is less than 20 percent of the interest of the overall Cloud Foundry project. Considering the revenue that Java attracts from enterprises, even in the face of languages such as Ruby and PHP, Cloud Foundry's growth into enterprise accounts could be less than smooth, given such low interest from the GitHub crowd.

Based on Google search trends for open source-based PaaS offerings -- VMware Cloud Foundry, Red Hat OpenShift, Amazon Beanstalk, and CloudBees' self-titled platform -- it's clear that the market is still wide open, with each candidate in the 15 to 25 percent adoption range.

If you add Google App Engine into the mix, interest in Google App Engine dwarfs the interest in Cloud Foundry and others by an order of magnitude.

I purposefully did not include the established platform vendors -- IBM, Microsoft, and Oracle -- in my level-of-interest comparison, as they would all dominate the rest. As much attention as Google App Engine has received and the likes of Cloud Foundry are getting today, they've yet to crack the enterprise market in a meaningful way.

It appears that Cloud Foundry is making good progress, but the road to enterprise acceptance, adoption, and revenue is well ahead of it.

I should state: "The postings on this site are my own and don't necessarily represent IBM's positions, strategies, or opinions.
