From 2009 to 2014 Dr Mike Norman was the Analyst at The Virtualization Practice for Open Source Cloud Computing. He covered PaaS, IaaS and associated services such as Database as a Service from an open source development and DevOps perspective. He has hands-on experience in many open source cloud technologies, and an extensive background in application lifecycle tooling; automated testing - functional, non-functional and security; digital business and DevOps. in 2014 he moved on to become Cloud Services Architect at JP Morgan Chase.

VMware should merge CloudFoundry with OpenStack

Agile Cloud DevelopmentWe suggest that to ensure CloudFoundry’s dominance, VMware should merge the dominant Open Source IaaS and PaaS initiatives into a single Foundation.

The PaaS market had a major false start in the period 2009 to 2012. The first PaaS vendors came to market with one of two premises

  • “we’ve got a really great platform you can use it if you want to”.  Good examples are Force.com (A PaaS derived from an IaaS – salesforce.com), Google App Engine and the original version of Azure
  •  “it’s a great place to run applications in a particular language” – good examples are Heroku (ruby) and PhpFog (PhP)

Since 2011 a second-generation of PaaS infrastructure has emerged which is exemplified by VMware’s CloudFoundry and Red Hat’s OpenShift. The biggest change between first and second generation PaaS is in the mindset. Instead of the first “P” in Platform as a service referring to “a Platform” it now refers to “any Platform”. In other words the job of the PaaS is to support any application in any language and deliver any set of services that any application might reasonably require. Whilst the first-generation PaaS was generally monolithic, the second-generation PaaS is usually capable of being implemented on a broad range of IaaS and/or virtual infrastructure, and the key factor is openness and diversity. Thus  CloudFoundry can be implemented on OpenStack. Continue reading VMware should merge CloudFoundry with OpenStack

AppFog – Polyglot Public/Private PaaS goes GA

CloudComputingAppFog (the company formerly known as PhpFog) has become the latest enthusiastic adopter of CloudFoundry to go to General Availability with a value-added implementation of the open source CloudFoundry.org stack.  The key differentiator is the RAM-based pricing policy around the Public Cloud offering – roughly $25 per GByte per month (first 2Gbytes are Free).

Private PaaS Update – Stackato 2.0 and Cumulogic 1.0

CloudComputingActiveState Stackato and CumuLogic are private PaaS.  Over the last few weeks Stackato has moved to a 2.0 version and CumuLogic has moved out of Beta to a 1.0 release.  CumuLogic 1.0 is a Java-only PaaS with support for Amazon, HP Cloud Services, and private clouds including Citrix CloudStack, Eucalyptus, OpenStack and VMware vSphere.   Stackato has a similar range of public and privae IaaS on which it operates (vSphere, KVM, XenServer, OpenStack, EC2 AMI, HP CS) but it has a much  broader set of language compatibilities  including .NET.ther new features in Version 2.0 are a centralized web-based management console and some support for charge-back (i.e. billing) through API.  Performace management is through integration with New Relic. There is  additional security support in multi-tenancy by using Linux Containers (LXC). Continue reading Private PaaS Update – Stackato 2.0 and Cumulogic 1.0

OpenShift — Pricing and Comparison to AWS

CloudComputingOn June 26, Red Hat announced a new version of OpenShift, and pricing for a future production offering (some time this year). You still can’t buy it but if you were able to buy it you’d know exactly how much it could cost – at least if you could work out what a “gear” is. Pricing allows us to start to compare it more meaningfully with other offerings. However rather than comparing with another PaaS offering, we think most people will be actually considering IaaS as an alternative, so we are going to do that comparison instead.

Ulteo OVD 3 – Open Source Remote Desktop

PresentationVirtualizationUlteo Open Virtual desktop is an Open Source alternative to Presentation Virtualization solutions such as Citrix XenApp, or Ericom PowerConnect or Quest vWorkspace. We looked at Ulteo back in 2009 and that post has consistently featured amongst various top 10 lists of posts on the site.  So we know you are interested but there were limitations in the Version 2 of Ulteo that made it suitable for a only a small number of use-cases. Ulteo have taken our views into account and responded to customer feedback and Ulteo OVD 3 can  now provide a viable alternative in the general marketplace – not just for those enteprises who actively adopt Open Source.
