You heard the buzzwords and drunk the kool-aid and now you want to move to the cloud, how do you do this? This has been the a fairly interesting question on the VMware Communities Podcast yesterday, when the vCloud team showed up to talk about the current reference architecture. Yet almost all the questions were about going to the cloud and not about the architecture. Does this mean people do not understand what is required to go to the cloud? I think so. So to take a few elements from the podcast and put them in writing is the goal of this article. The Simple Steps to move to the cloud.
For an IT department these are perilous times indeed. All around you public cloud vendors are offering IT services on an easy to procure, elastic and often inexpensive basis. Many of the developers in your organization may have already concluded that getting resources provisioned for development and test projects is easier at Amazon.com than it is through your internally offered processes. If you are aware that this is happening you can console yourself by saying, “it is only development – not production”, but you should wonder what should you do to make sure that those workloads come back when they do go into production.

One of the key themes of VMworld 2010 was “IT as a Service”. IT as a Service is simply the next logical step beyond virtualization. The key parts of the evolution from virtualization to IT as a Service is that IT as a Service involves a self-service aspect where business constituents can select “services” that are then automatically provisioned and delivered to them, and the notion of secure multi-tenancy within an enterprise’s data center for the purpose of separating the environments of multiple business units, departments or divisions much in the same way that a public cloud vendor must separate the environments of Coke and Pepsi.

rPath has announced that they have added automated model based deployment for Windows applications to their existing capabilities for Linux based applications. Before we go into rPath and this announcement in some more detail, let’s look at the environments that rPath is addressing and now they are changing:
- Most enterprises have large numbers of business critical applications (for most companies the number is over 100)
- A significant portion of these applications are custom developed by the enterprise, and subject to continued feature enhancement and maintenance Continue reading rPath Addresses Automated Applications Deployment Across Physical, Virtual and Cloud Envionments
We’ve been following Eucalyptus for some time, and they recently invited us to a briefing about a new alliance called NRE, which is a credible group of independent vendors, newScale, rPath and Eucalyptus.
This wasn’t spun from an Open Source prespective and it was interesting to see the Eucalyptus positioning to the general marketplace. Eucalyptus is positioned as the “leading” Open Source cloud, the benefit of Open Source being it is “on your own terms”. It offers IAAS in the data center, just like Amazon Web Services. It is Elastic, based on industry standard APIs, hypervisor agnostic, supports both Windows & Linux guests, and has a huge ecosystem. It’s the elasticity and the scalability that are driving the adoption. Pricing is secondary, and you also get the feeling that it’s not traditional enterprises which are picking it up.
