This week featured several major developments from the enterprise to the consumer cloud, first and foremost the announcement that VMware vSphere 5.0 will be available in late August. The cloud OS features several improvements to existing APIs, and the addition of a new one dedicated for array management, among other things. SiliconANGLE covered the vSphere 5.0 announcement live.

Another tech giant that had some big news this week is IBM.  Big Blue is building two new datacenters in Japan. The first, dedicated to its SmartCloud Enterprise platform offering, will be located in Makuhari, while the location of the second facility, which is set to power Lotus Live, is still pending. IBM already has a strong presence in the Asia Pacific region, thanks to, among other things, 13 cloud labs spread throughout China, India, Singapore and other locations.

Virtualization solutions maker Citrix also had some news – the acquisition of Cloud.com for $200 million. The startup’s CloudStack offering lets users pool VM hypervisors, and has already gained Cloud.com 64 customers including Zynga, Tata Communications, and Koream telco KT.  Citrix and Cloud.com are both members of the OpenStack community, and the deal is certainly not the only open-source cloud development that was announced this week.

Gluster, an open-source storage solutions maker, added Rob Bearden, the president and COO of HortonWorks, to its board. The company also joined the Linux Foundation along with basysKom, Codero and Nixu Open.

Over in the consumer cloud, Microsoft and Dropbox had some updates as well. The former is hoping to slash prices on Windows Phone 7 devices to be competitive in the market, while it’s also gaining support for Office 365. Dropbox in turn, a personal cloud storage company, is reportedly in talks to raise anywhere from $200 million to $300 million from investors.
