Lots of big news in the enterprise world this week, including Microsoft's very, very pretty penny for Skype and the release of Yammer Desktop 2.0. 

Microsoft Buys Skype for US$ 8.5 Bil

Rumors of both Facebook and Google purchasing Skype have been zipping around the Web for some time now, but the prize ultimately went to Microsoft for a whopping US$ 8.5 billion. 

This new deal marks Microsoft's largest acquisition ever, and will certainly lend some useful capabilities to Windows Phone 7 devices as well as desktops. It also gives Microsoft a boost in social interaction via the likes of Facebook, and puts it on a par with Apple's FaceTime and Google's Talk apps.

According to Microsoft, this acquisition will spin off a new Skype division that will see Skype CEO Tony Bates as head honcho reporting directly to Steve Ballmer himself.

"Microsoft and Skype share the vision of bringing software innovation and products to our customers,” said Bates. “Together, we will be able to accelerate Skype's plans to extend our global community and introduce new ways for everyone to communicate and collaborate."

Yammer Introduces Desktop 2.0

Yammer's (news, site) new Desktop 2.0 offers users a collection of advanced social networking and messaging features.

The real time app presents a practical set of tabs with the current feed, direct messages, notifications and a search option. New messages can pop up over the desktop, nixing the need to keep a browser or the app on top.

It is also significantly easier to follow conversations, as replies are displayed underneath the original message. Further, if you work with several colleagues, notifications are on a different tab to keep them distinct:

Available for Windows and Mac, there is now no excuse for missing a Yammer message, no matter where you are or what you're doing.

Together, Yammer and NetSuite Socialize Business Data

SuiteWorld 2011 kicked off this week with a cool little announcement: NetSuite (news, site) and Yammer have joined forces for the greater good of mission-critical data. In other words, such information can now be socialized within the enterprise.

A new SuiteApp called SuiteSocial allows users to socialize business data for use with social networking and collaboration applications.

For example, users can 'follow' records of interest in NetSuite, and SuiteSocial takes the activities and updates that occur around them and syndicates them to an external social stream or feed.

The NetSuite SuiteSocial content is integrated into Yammer's new Activity Streams feature. Activity Streams are currently displayed as a separate feed in Yammer and in the future the most relevant stories will be elevated into the user’s primary feed.

“Yammer and NetSuite share a common vision where systems of record such as NetSuite can communicate through systems of engagement such as Yammer to make enterprise collaboration and communication more efficient,” said Zach Nelson, President and Chief Executive Officer, NetSuite. “The new combination of NetSuite and Yammer is an important advance for NetSuite customers to enable easy communication and collaboration around activity taking place within NetSuite – in a private and social Yammer environment.”

eXo Portal Introduces Support for Ruby, Partner Red Hat Releases Multi-Language PaaS

eXo (news, site) is well-known for its Java portal and user experience technologies, but this week the company announced it's spreading its wings with the addition of Ruby and Git to its eXo Cloud IDE. The inclusion of Git will enable direct deployment to Red Hat's new OpenShift platform-as-a-service.

Red Hat’s PaaS supports multiple development frameworks, including languages Java, Python, PHP and Ruby, and frameworks Spring, Seam, Weld, CDI, Rails, Rack, Symfony, Zend Framework, Twisted, Django and Java EE. Openshift includes SQL and NoSQL data stores (MySQL, MongoDB and Memcached) and a distributed file system. It builds on the Apache’s RESTful Deltacloud cloud interoperability standard and allows developers to run their applications on any Red Hat Certified Public Cloud Provider, eliminating the lock-in associated with proprietary PaaS vendors APIs.
