Public Cloud Reality: Support Responsibility

CloudComputingThe Public Cloud Reality around support responsibility is not something often considered, instead we are looking at SLAs, legal documents, compliance documents, and many other items. Do we consider who is ultimately responsible when something goes wrong within the cloud? Is your Cloud provider a full partner or do they limit themselves to a small subset of the implementation? Do they have 24/7 support will be covered by the SLA, but what type of support? How qualified are the clouds support teams to help you with your application’s problems? Who is responsible?

Waratek – forget VMware, just virtualize the JVM

Agile Cloud DevelopmentWaratek is a one-off company with a disruptive technology (remember VMware was like this once) that forces you to reset your undertanding of how things could work.  Waratek’s big idea is that you virtualize as high up the stack as you can because that gives you the best benefit in terms of sharing infrastructure. So rather than replicating operating systems on a hypervisor accessing shared hardware, you simply replicate as small a part as possible of the Java Virtual Machine (JVM).  Everything else (hardware, operating system and most of the JVM) is shared.

Are We Missing a Category of Cloud Computing?

CloudComputingSome 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).
