Recently, OStatic covered Eucalyptus, an open source infrastructure for cloud computing on clusters that duplicates the functionality of Amazon's EC2, using the Amazon command-line tools directly. We've also been covering several interesting projects focused on cloud computing.

Eucalyptus Systems is set to gather reseller partners old and new in San Francisco on June 22. The reason: It’s time for Eucalyptus to lay out where their open-source cloud platform stands, along with potential channel partner opportunities. Here’s what to expect.

NASA is dropping Eucalyptus from its Nebula infrastructure cloud not only because its engineers believe the open source platform can't achieve the sort of scale they require, but also because it isn't entirely open source.

For the Ubuntu cloud strategy to succeed, Canonical is going to need a big assist from Eucalyptus Systems - which makes the engine within the Ubuntu Enterprise Cloud (UEC). But who exactly is Eucalyptus and is the company making progress with its own cloud efforts? Here's an update.

Terracotta and Eucalyptus Systems, both open source startups, have announced a new joint partnership. According to the companies, which specialise in scalability for Java applications and the private cloud platform, the partnership will "provide enterprises with an open source solution that maximizes data scalability and application performance in a private cloud environment".

There’s a real explosion of cloud platforms and management tools, it seems you can’t swing a dead cat without hitting one these days. In the commercial proprietary solutions space you have – CA’s 3Terra AppLogic, Enomaly, Nimbula, RightScale. In open source there are Eucalyptus, Cloud.com, Open Nebula and Ubuntu Enterprise Cloud. There are a bunch more that I failed to mention.

On July 1, Canonical, the company behind Ubuntu in partnership with Eucalyptus Systems, an open-source cloud infrastructure firm, will be launching Ubuntu Enterprise Cloud Services.
