What is the total cost of ownership, TCO, of the cloud? When we think of the cloud, we think of using applications in the cloud such as Salesforce, Box.net, and others. We may even consider using security as a service tool such as Zscaler and others. In some cases we also think of placing our own workloads in the cloud using Amazon and other tools. The real question that comes to mind is the TCO of the cloud? Not now, but long term.

The secure hybrid cloud encompasses a complex environment with a complex set of security requirements spanning the data center (or data closet), end user computing devices, and various cloud services. The entry point to the entire hybrid cloud is some form of End User Computing device whether that is a smart phone, tablet, laptop, or even a desktop computer. Once you enter the hybrid cloud, you may be taken to a cloud service or to your data center. The goal is to understand how the data flows through out this environment in order to properly secure it and therefore secure the hybrid cloud, but since it is a complex environment, we need a simpler way to view this environment.
CERN goes hybrid: Have you heard the news that CERN is going to the cloud? The term CERN is used to refer to the European laboratory located in the northwest suburbs of Geneva snug on the Switzerland border. Its main function is to provide the particle accelerators and other laboratory infrastructure needed to perform high-energy physics research. CERN was originally established in 1954 as The European Organization for Nuclear Research. Research at the facility has moved past nuclear research, and it has fully expanded into one of the largest laboratories for particle physics research, using the Large Hadron Collider. On an interesting side note, the main site at CERN is also the birthplace of the World Wide Web; before that, these facilities were a major wide-area networking hub for sharing the scientists’ research with different scientists located elsewhere.
The 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?
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)
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).
