It’s no secret that I’m keen on the idea of Cloud Computing (and cloud storage in particular), so the concept of evolving standardisation is extremely exciting. I would also contend that for certain pieces of the cloud storage infrastructure we do need standards: Security, authentication, and the ability to dynamically switch workloads.

Championing “open” and calling for standards has become the first stalling action by late-movers in technology spaces. They see opportunity passing by and try to hold back progress and FUD the market by yelling about proprietary solutions, vendor lock-in, and a lack of standards. Many well-intentioned IT folks follow along: After all, who doesn’t want openness, standardization, and interoperability?

As cloud computing becomes more mainstream, investors will start looking to get in on the act. With that in mind, a friend and I began discussing which public companies were getting into the cloud computing market and to what extent. I have put together the following list, and encourage comments, suggestions, and contributions.

While the bulk of Sun-related news this week relates to reported talks of a buyout by IBM, the company took a break from negotiations to introduce their own cloud computing and storage infrastructure, challenging Amazon, Google, Rackspace, and perhaps VMware, Microsoft, and Nirvanix.
