Open cloud news this week brought with it some new competition, some reflection on existing competitors and some unexpected cooperation. I've also thrown in a short counter perspective on the issue of portability -- is it a myth?
What did you think was this week's top open cloud story? Please tell me in the comments, below. I'd love to hear from you. Your feedback will help me refine this list and and make it more useful to the community. Thanks!
First the competition:
Open source cloud toolkit funded by EU Optimis project to arrive in June, ComputerWorld UK 
Funded by the European Union to make Europe more “cloud friendly,” the Optmis project is gaining steam. The European OpenStack equivalent is also getting some pressure to partner  with OpenStack.
Red Hat debuts OpenShift Origin project, takes swipe at VMware's Cloud Foundry, ZDNet 
The Origin project will serve as the upstream for code and improvements to OpenShift, Red Hat’s PaaS, which today runs on Amazon Web Services cloud and competes against VMware’s open source Cloud Foundry.
Marten Mickos: For Eucalyptus open cloud is more than open code, TechWorld 
Mickos compares cloud storage to depositing money in the bank. All depositors should have free and open access to their stored data. He also comments on Eucalyptus’ partnership with Amazon to support Amazon Web Services’ API, saying it gives his company a competitive advantage over OpenStack, which doesn’t have a similar deal with Amazon.
Cooperation (or just less competition):
Thanks to Piston, OpenStack gets an unlikely ally in VMware, GigaOM 
Piston Cloud wants to bring together the Cloud Foundry PaaS with the OpenStack IaaS. Wasn’t OpenStack in part a play against VMWare, as well as Amazon Web Services?
Open Compute one year later. Bigger, badder and less disruptive than we thought, GigaOm 
With the growth of Facebook’s Open Compute open hardware project and OpenStack it’s possible to build an entirely open hardware infrastructure layer and companies are demanding more flexibility. The big data ecosystem has adjusted, with companies like Dell and HP offering new server and storage designs compatible with Open Rack.
A different perspective:
Two Cloud Myths Busted: Lock-In and Locked Up, PCWorld 
Portability is a favorite mantra of open cloud supporters. But is portability a myth? This commentary says profitability and intellectual property values will always trump portability.
