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. Continue reading News: Piston Cloud does CloudFoundry on OpenStack
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.
A customer recently asked me, can we virtualize our Tier 1 App that receives 7Billion requests per day? My initial response was, on how many servers? Their answer was 15. This is quite a shocking set of numbers to consider. Add into this numbers such as 150K sessions per second, the need for a firewall, and sub-second response time and you end up with a few more shocking numbers. So could such workloads be virtualized? or is it too big for Virtualization? Continue reading What is Considered Too Big for Virtualization?
We, here at The Virtualization Practice, are getting ready to have a cloud presence. Since we ‘eat our own dogfood’ with a 100% Virtual Environment, we are gearing up to move some of those workloads into a hybrid cloud. We already use some cloud resources, but now is the time to look at other workloads. Why we are moving to the cloud is three fold: how can we write about various aspects of being a tenant in the cloud, if we are not one; a recent power outage at the grid level; and a upcoming data center move. Two of these reasons are all about business continuity with the first being what we do. While we already have a cloud running within our own environment, it is time to branch out.

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). Continue reading RackSpace calls Citrix’s Bluff over CloudStack. Citrix Folds.
Nimbula is an Infrastructure as a Service (IaaS) software stack analogous in its target market and its business model to commercial software like vCloud. It sits alongside a number of open source software products like Eucalyptus, Cloud.com (Citrix) and OpenStac k(Rackspace et al.) as well as the Amazon Web Service, and other hosted services.
Nimbula is a relatively-late entrant to the market, and is in some sense a second-attempt at IaaS, since it was developed by a lot of the original team that built AWS. It is a venture-backed statrup with a significant funding base, and is quite early in its adoption curve. There is a free version (limited to 40 cores) but this is not an Open Source product.
