ActiveState Stackato – A Diverse Private PaaS

CloudComputingActiveState has created a Private PaaS  that supports Perl and Python as well as Java, and is based on the Open Source CloudFoundry distribution, packaged and distributed in a VM image, or installed to a wide range of IaaS platforms (public or private).

ActiveState is well known in Open Source communities as packaging/distribution vendor for dynamic languages – Perl, Python and Tcl.  A sort of Red Hat for dynamic development languages.  It also has a Komodo IDE for these languages, and a strong pedigree in contributing back into the Open Source projects which it packages. Stackato is also essentially a packaging of these and other Open Source technologies. It’s an interesting take on the PaaS space – PaaS becomes a packaging problem – just like the Linux Distro. For the customer, the choice of PaaS/Distro is partly about the  breadth in the package and partly the mix of pricing, support and warranty offered by the PaaS/Distro.

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.

AppFog – Extending the scope of Cloud Foundry

There is now a huge amount of movement in the area of what we have called “Diverse” Platform as a Service i.e. PaaS that delivers a number of different application infrastructure technologies on a mix-and-match basis and where there is no proprietary  technology layer at any point in the platform stack. Amongst these we would include OpenShift, Cumulogic and CloudFoundry from our recent set of posts.  AppFog sits in this category, and the fact that it has been recently renamed from PHPFog highlights a major trend in the space, the vendors typically start by developing a single technology, build an initial business plan and gain some market traction within that niche, and then move on to supporting a broader range of platforms.
