Governance defines who's responsible for what and the policies and procedures that users need to follow. Cloud governance requires governing your own infrastructure as well as infrastructure that you don't totally control. Cloud governance has two key components: understanding compliance and risk and business performance goals.

Infrastructure as a Service Cloud infrastructure services or "Infrastructure as a Service (IaaS)" delivers computer infrastructure, typically a platform virtualization environment, as a service. Rather than purchasing servers, software, data centre space or network equipment, clients instead buy those resources as a fully outsourced service. The service is typically billed on a utility computing basis and amount of resources consumed ( and therefore the cost) will typically reflect the level of activity. It is an evolution of web hosting and virtual private server offerings.

A standard is an agreed-upon approach for doing something. Cloud standards ensure interoperability, so you can take tools, applications, virtual images, and more, and use them in another cloud environment without having to do any reworking. Portability lets you take one application or instance running on one vendor's implementation and deploy it on another vendor's implementation.

The cloud is elastic, meaning that resource allocations can get bigger or smaller depending on demand. Elasticity enables scalability, which means that the cloud can scale upward for peak demand and downward for lighter demand. Scalability also means that an application can scale when adding users and when application requirements change.

Software as a Service Cloud application services, whereby applications are delivered over the Internet by the provider, so that the applications don't have to be purchased, installed, and run on the customer's computers. SaaS providers were previously refered to as ASP ( application service providers). In the SaaS layer, the service provider hosts the software so you don't need to install it, manage it, or by hardware for it. All you have to do is connect and use it. SaaS examples include customer relationship management as a service.
