Virtualization Certification, It used to be just VMware and the VCP, but things have changed as other players get involved and I thought it would be interesting to see what virtualization certification options there are out there.
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.
As mentioned in a couple of recent posts, I have been building a prototype application using Open Source technologies that I plan to install on a number of available PaaS cloud platforms. The application is written in Groovy (with some bits in Java) and built on the Grails framework. This article is about my use of RedHat OpenShift PaaS and the controls available.
Red Hat’s Cloud is to play at all levels in the stack, from IaaS and PaaS through to hypervisor and of course operating system. Each layer is comparable to offerings from competitors.except for MRG – Messaging Realtime and Grid, of which version 2.0 has just been released.
As mentioned in my previous piece I’ve been doing some prototyping using SpringSource’s Grails. Grails can be thought of as the top of the stack. If you pick up Grails you would naturally pull in the other pieces of SpringSource, including vFabric and ultimately vFoundry. In a future post I will deal with what happens when you stick Grails onto vFoundry, but at this stage I’ve been assessing the health of the SpringSource Ecosystem.
The announcement of CloudFoundry means the public declaration of full on war between VMware, and the two traditional OS vendors, Microsoft and Red Hat. Both traditional (not quite legacy yet) OS vendors are going to have to rapidly bolster their own PaaS cloud offerings. This will be a particular challenge for Microsoft as Microsoft has always gravitated strongly towards having a tightly integrated stack of software, and not being very open to open source frameworks like Spring, Ruby, and PHP.
