Red Hat maintains that VMware's claims of openness in the cloud are bogus.
During a webcast today, Scott Crenshaw, Vice President and General Manager of Red Hat's Cloud Business Unit, said he's glad to see VMware working with partners to develop its cloud business but insisted that VMware's is a lock-in solution.
"VMware will be open the day they open source vSphere ... everything else is window dressing," said Crenshaw, saying that VMware is taking what is a closed proprietary solution and trying to make it more open through standards and partnerships. "They're taking baby steps but I wouldnt call it open."
vSphere is VMware's virtualization platform for building cloud infrastructures.
The Red Hat exec made his comments shortly after EMC-VMware and partner Atos announced an open cloud computing alliance called Canopy. During a press conference about Canopy on Wednesday, one Atos exec acknowledged the reference to open cloud computing related to Java and the use of other frameworks -- not open source.
Meanwhile, Red Hat, which is working on its own platform for building cloud infrastructures, announced that its DeltaCloud REST API project has been elevated to one of Apache's top level open source projects -- up from the incubator level.
Yes, Red Hat's CloudForms -- that company's virtualization plaform for building a cloud infrastructure -- includes the DeltaCloud API. It is still in beta testing.
