Just like the entire IT industry, the cloud computing market is evolving. It’s expanding its borders further and further, to reach a broad spectrum of users ranging from large enterprises to the end customers, and every new development we cover has an impact on the industry.

This past week in the cloud has seen a hefty number of updates crossing the wire, including the AWS technical difficulties which began as of 4:41 a.m.  Eastern time.  Latency and connectivity issues affected a number of companies in the Eastern availability zone to experience technical difficulties. This means some Foursquare, Quora, and HotSuite users are unable to access these services, as well as well as a number of other leveraging Amazon’s increasingly popular cloud services.

The cloud equals good business, and VMware is also profiting from this enormous industry. The company held its earnings call this week, and reported an impressive 33 percent year-over-year revenue growth. It has also raised its estimates for the second quarter of 2011, which made its stock leap by at least 6 percent.

Over at the open-source front, the latest release of the cloud OS project codenamed Cactus has debuted. Cactus brings with it including OpenStack Compute support for all support for all major virtualization technologies. Cactus also features IPv6 support, and the new OpenStack API 1.1 which now enables the creation of extensions and more custom & management options.

The personal cloud space has also seen a development this past week, with the release of the latest update to the Evernote Android app. The popular note-taking app now allows users to link accounts, collaborate notebooks, auto-sync and integration with Twitter and Facebook.

Last but not least, Quantum and NetApp have established a new partnership. NetApp will resell the backup, recovery and archiving company’s StorNext file sharing and collaboration platform.
