State of Secure Multitenancy Today

On 9/22 was held the Virtualization Security Podcast featuring Anil Karmel, Solutions Architect at Los Alamos National Library (LANL), to discuss their implementation of secure multi-tenant Cloud. LANL makes extensive use of the entire VMware product suite from vCloud Director down to the vShield components to implement their SMT cloud. They have also added into their cloud their own intellectual property to improve overall cloud security. It was a very interesting conversation about the state of SMT today.

Cumulogic Launches Highly Diverse PaaS Cloud

Over the last few months, we have identified a trend towards “diversity” in the PaaS provider marketplace. Platform as a Service has become Platforms as a Service, the providers are offering multiple choices at each layer of the platform infrastructure, and seeing their role as automating the provisioning of  properly configured instances as required at each layer of the stack.

On Aug 2nd, there was another entrant to this “diverse” PaaS provider marketplace  called Cumulogic,  a startup with a PaaS cloud positioned alongside Red Hat OpenShift and VMware CloudFoundry that we identified earlier. Continue reading Cumulogic Launches Highly Diverse PaaS Cloud

PaaS Platform experience – Red Hat OpenShift

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. The choice to go with this set of technologies is documented in Why would a Developer choose VMware? and my experiences leveraging the Open Source ecosystem around Groovy/Grails is outlined in VMware’s SpringSource Ecosystem

Subsequent to those posts I still feel pretty comfortable about the technology choices, although I have had to move away from the “scaffolded” user interface provided by Grails and build some javascript widgetry that sits in the browser. For this I chose another technology I happen to be familiar with called Dojo. It’s essentially a set of compressed javascript files that can be served out from any web server, or even linked to dynamically at one of three externally-hosted sites. It can be used to make a web application look like a proper enterprise application with menus, tabbed panels, grids and charts etc. I glued it back into the Grails Controller/Domain layer via json and Xhr (Ajax).

Red Hat releases MRG 2.0 – messaging for the cloud.

We’ve touched on Red Hat’s Cloud strategy in a number of posts. To summarize they’re trying to play at all levels in the stack, from IAAS and PaaS through to hypervisor and of course operating system. All layers are open, and as you get further down the stack towards virtualization they are pushing KVM but they are clear that they have to co-exist with Microsoft and VMware.  In the IaaS layer they have DeltaCloud, which is nominally open but is really a Red Hat product with an open veneer. In the PaaS layer they have a stack of really good middleware from JBoss, and an openness to a whole bunch of Java/JVM and non-JVM languages.  They’re punting this out to the world as OpenShift.

So far, although there are nuances that differ from other vendors, the main conclusion is that each individual layer is comparable to offerings from competitors.  However, there is one layer that sets Red Hat apart from competitive offerings, known as MRG – Messaging Realtime and Grid, pronounced “Merge”.  If you’re wondering what this is, it seems also that some of are bits of Red Hat’s marketing department that haven’t got a clue either because the market positioning is a bit vague. Continue reading Red Hat releases MRG 2.0 – messaging for the cloud.

Microsoft relaxes licensing rules to elevate its customers to the cloud

Microsoft is making changes to its licensing policies to provide enterprise customers with a fast track to the cloud. The changes dubbed “License Mobility” announced at the Microsoft Hosting Summit in March this year,will move will allow customers with Software Assurance to move their applications to a cloud services provider without paying a premium for the added flexibility this will bring.

The changes which are due to take effect on July 1 this year should benefit Microsoft, its customers, and cloud service providers equally.  Continue reading Microsoft relaxes licensing rules to elevate its customers to the cloud

Citrix announces IaaS Project Olympus built on OpenStack

I like OpenStack (the Open Source IaaS Cloud Platform intiative), partly because of the model of open innovation and permissive licencing (which reminds me of my time at Eclipse) and partly because even within the existing governance model (which I have criticised) there is the opportunity for different agendas to surface and to drive the project in different directions and this diversity makes an analyst’s life more interesting.

One of the most intriguing names that has hitherto been at the periphery of the OpenStack initiative is Citrix. Up until last week, Citrix’s contribution was to ensure OpenStack ran on XenServer, something which I’m sure Citrix cares about, but perhaps wasn’t top of the list of requirements for the rest of the world. However, this week at it’s Synergy event, Citrix made some more sigificant announcements about Project Olympus, through which it aims to provide (in collaboration with Dell and Rackspace) a route to commercial exploitation of the OpenStack codebase.
