Migrating to the Cloud: OpenStack or vCloud?

CloudComputingWe, 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.

RackSpace calls Citrix’s Bluff over CloudStack. Citrix Folds.

CloudComputingCitrix 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).

Virtualization Security is NOT Cloud Security!

I and others look at Virtualization Security constructs with an eye towards Cloud Security, but they are not necessarily the same. Granted for some clouds, virtualization security can lead to cloud security but this really depends on how the cloud’s architecture. Even so, what we know from Virtualization Security WILL apply to Cloud Security and will be the basis for best practices. But you say, my cloud does not use Virtualizaiton? Ah ha, I say, but it is still a cloud? And that implies there are similar security concerns. This was the discussion on the 1/26 Virtualization Security Podcast.

Cloud: Developing over the Chasm in 2011

In 2012  should you use Virtual Infrastructure, Infrastructure Cloud (IaaS) or Platform Cloud (PaaS).  Which one has crossed the Chasm?

Now, of course, this is a simplified version of the question, because in almost all cases Infrastructure Clouds and Platform Clouds are built on a Virtual Environment, and in most cases Platform Cloud is built on an 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 making decisions to maximise the productivity of a development team – rather than on the “shininess” of the technology – by developing in the cloud.

Nimbula 1.5 delivers federated IaaS

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.
