Virtualization, public cloud, private cloud, IaaS, PaaS, SaaS, Ugh!
If you are confused on what the cloud is and isn’t you aren’t alone. The IT industry has long been a fan of marketing what is “hot.” We are going to try and do our part to clearly define our services and educate our customers when needed. That said, here is my take on computing and the struggle for the industry to define the cloud:
Silo computing: 1 application per 1 physical server
Virtualization: Many applications per 1 physical server
Infrastructure as a Service (IaaS) or public cloud: pay as you go server and storage slices in a multi-tenant and highly scalable environment
Private cloud: a resource pool dedicated specifically to your company. Service providers like Appica can deliver a private cloud environment or it can be developed and managed in-house. In either case there is a capacity limit based upon the physical resources deployed
Software as a Service (SaaS): third party hosted software application delivery usually accessed via a browser or client such as Hosted Microsoft Exchange or Gmail
Platform as a Service (PaaS): a business application platform stack that allows development and utilization of resources. Shared hosting would be yesterday’s PaaS whereby a customer uploads html to a third party managed platform
Appica is an IaaS service offering that is available in a multi-tenant or dedicated environment for private cloud deployments. If you want to further discuss the benefits of IaaS vs. virtualization we welcome your call.
