Ulteo Open Virtual desktop is an Open Source alternative to Presentation Virtualization solutions such as Citrix XenApp, or Ericom PowerConnect or Quest vWorkspace. We looked at Ulteo back in 2009 and that post has consistently featured amongst various top 10 lists of posts on the site. So we know you are interested but there were limitations in the Version 2 of Ulteo that made it suitable for a only a small number of use-cases. Ulteo have taken our views into account and responded to customer feedback and Ulteo OVD 3 can now provide a viable alternative in the general marketplace – not just for those enteprises who actively adopt Open Source.
We asked OpenStack recently whether they were going to do PaaS, they said that this was happening in the community around them, and today we have an announcement of one way of doing it: with VMware’s Open Source CloudFoundry.
The OpenStack Governance Model is changing to remove the dominance of Rackspace by establishing an independent foundation. We were very critical of the old model, so we spoke to Rackspace to understand what was happening.
Citrix has given up Project Olympus which was based on the Open Source OpenStack platform in favor of its own Open Source CloudStack initiative (formerly known as Cloud.com), which it is contributing to the Apache foundation and has re-licensed under the partner-friendly Apache Open Source license (rather than the GPL).
ActiveState has created a Private PaaS that supports Perl and Python as well as Java, and is based on the Open Source CloudFoundry distribution, packaged and distributed in a VM image, or installed to a wide range of IaaS platforms (public or private).
ActiveState is well known in Open Source communities as packaging/distribution vendor for dynamic languages – Perl, Python and Tcl. A sort of Red Hat for dynamic development languages. It also has a Komodo IDE for these languages, and a strong pedigree in contributing back into the Open Source projects which it packages. Stackato is also essentially a packaging of these and other Open Source technologies. It’s an interesting take on the PaaS space – PaaS becomes a packaging problem – just like the Linux Distro. For the customer, the choice of PaaS/Distro is partly about the breadth in the package and partly the mix of pricing, support and warranty offered by the PaaS/Distro.
Now, of course, this is a simplified version of the question, because in almost all cases Infrastructure Clouds and Platform Clouds are built on Virtual Infrastructure, and in most cases Platform Cloud is built on Infrastructure Cloud, so the question is really about how far into the Cloud you should be prepared to go. My perspective here is of a development manager – someone who is charged with building a new application. I’m thinking as a development manager not a developer and I’m taking decisions to maximise the productivity of a development team – rather than on the “shininess” of the technology.
