Enterprise organisations are constantly being asked to do more work with fewer people, as the size and complexity of infrastructure and applications continue to grow unabated.
VIRTUALISATION VENDOR Citrix has released its open source Xen Server 6.2 to go up against VMware's closed source free Vsphere hypervisor. Citrix for years has maintained a free, open source version of its Xen hypervisor but it has been losing ground to KVM and in particular VMware's free Vsphere hypervisor.
According to Citrix, Xen Server 6.2 supports Cloud Stack, Open Stack and Citrix's own Cloud Platform. Sameer Dholakia, group VP and GM of Citrix's Cloud Platforms Group said, "The cloud era has brought a lot of exciting opportunities for data center infrastructure, but the reality is that one size doesn't fit all when it comes to virtualization. Citrix said its Xen Server 6.2 supports its Xen Desktop software, including Intellicache and Dynamic Memory Control. Citrix will be hoping that as firms get used to the free version of Xen Server they will shell out for the full versions that cost up to £3,250.
Cloud9 – a startup offering developers an IDE that runs entirely on the web – has announced that its creation now plugs directly into the Node.js service run by Node chief steward Joyent. You can now build a Node app, debug it, and deploy it without leaving the the web-based IDE.


Unveiled this past March, Cloud9 is an online IDE (integrated development environment) designed specifically for building applications with JavaScript, including Node, the event-driven, server-side development platform based on Google's V8 JavaScript engine. Previously, you could build and debug Node apps with Cloud9, but you couldn't deploy – at least not directly.
In addition to Node and JavaScript, the Cloud9 IDE handles HTML, CSS, and – to a lesser degree – CoffeeScript, Ruby, and PHP.
The Bespin project has been rolled into the open source editor at the heart of Cloud9, known as Ace.
Cloud9 carries a $15 a month subscription fee, but a free, limited version is also available.

Now the firm has released Xen Server 6.2 and a community website that the firm hopes will help increase support for its open source hypervisor. The firm touted support for the latest guest operating systems including Microsoft's Windows 8 and Windows Server 2012. The firm said it has added Desktop Director alerts so that administrators can be notified of low resources to try to prevent virtual machines from becoming unusuable.
However, Citrix's continued support of its free, open source Xen Serven means that VMware will have to continue offering a free version of Vsphere if it doesn't want to leave a gap in the market. The company is now developing a version of its IDE for Python, and this version, currently in "preview mode", will integrate with Google's App Engine. Though Mozilla was previously developing its own "cloud-based" IDE – known as "Bespin" and then "Skywriter" – the open source outfit has now put its weight behind Cloud9.
The platform is also a part of Joyent's SDC6 software, which lets ISPs and other outfits build their own infrastructure clouds.
