Which cloud service will be king of the cloud? Cloud computing has taken off in functionality and practicality over the last few years, so that now we have three fully defined service models of cloud computing:
- Infrastructure as a service (IaaS)
- Platform as a service (PaaS)
- Software as a service (SaaS) Continue reading King of the Cloud

We opened this years virtualization security podcast with Phil Cox, the “Security Guy” at Rightscale, who is working through a tangled problem to meet compliance and auditing goals within the cloud. Rightscale is a 100% cloud based company delivering a solution that is also SaaS based. As such they often run directly into SaaS related issues. Rightscale has been running into a problem with the simplest of auditing requirements: how to know when someone has logged in. This problem spans nearly all their 100s of SaaS providers used to run their business. Continue reading SaaS Auditing: Knowing who did what
Some time ago, categories of public cloud computing were established. First of all, a distinction was created on who owned the cloud, with private (it is yours), hybrid (you are renting it, but not sharing it with anyone), and public (you are renting it, and you are sharing the infrastructure with an unknown number and type of other entities) having been defined. Then we created Infrastructure-as-a-Service – IaaS (a service consisting of either the container for the OS, or the container and the OS in it), Platform-as-a-Service – PaaS (a service consisting of IaaS plus all of the application services (web server, application server, database server, and language run times) that an application needs, and Software -as-a-Service – SaaS (the entire application is delivered over the Internet, typically by the application vendor (SalesForce.com being a good example).

If you ever want to polarize a group of IT professionals, all you need do is drop ITIL into the conversation. For some people ITIL is the devil incarnate. For others it is the Holy Grail–an unattainable symbol of union with the divine.
For VMWare it’s clearly the devil. In his VMworld keynote last month, VMware CEO Pat Gelsinger said that the company is “putting aside ITIL and CMDB in favour of process that works for cloud,” a position that Citrix clearly disagrees with after announcing that it had completed the acquisition of New Zealand-based startup Beetil, which is rapidly making a name for itself with a SaaS-based service management offering that delivers a readily accessible pragmatic approach to ITIL. Continue reading ITIL as a Service
There has been quite a lot of twitter traffic about the FrankenCloud recently: A cloud with more than one type of hypervisor underneath it. One example, is to build a cloud using Hyper-V three and vSphere, both managed through Microsoft System Center. Another example, is to build a cloud using Hyper-V, KVM, and vSphere all managed through HotLink. But is this a desired cloud topology? Continue reading Enter the FrankenCloud: Or Do we really care about the Hypervisor?
