The Different Types of Cloud Computing

This is a sidebar to our Article “Exploring Cloud Computing“.

Here is a list of the five most common types of cloud computing.

Software as a Service (SaaS) – a single application, library of applications, an API of web services, infrasructure or development platform users who are not necessarily aware of one another interact with through their browsers; Salesforce.com, Google Apps and Zoho Apps are a few examples. Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) are closely related derivatives of SaaS.

Utility Computing – specialized apps coupled with dynamically reconfigurable resources with often a significant reliance on virtualization for ease of maintenance, portability and scalability.

Managed Services – piecemeal software extensions for existing IT departments such as virus scanners for email or remote desktop managers.

Service Commerce Platforms – a hybrid of SaaS and Managed Services presenting an automated service bureau. Think ADP.

Internet Integration – a combination of any or all of the above, from the same or different providers over a common “service bus,” today in its infancy. The “bus” is a standardized data transfer subsystem which allows different providers’ service elements to be plugged in and swapped out, allowing data to be shared across different providers and giving competitive choice to the user.

These services are provided by “cloud service providers,” also called “cloud vendors” or “cloud providers” for short. A “public cloud” provider is one who purveys services to pretty much anyone on the Internet. The largest public cloud provider in the world is amazon.com’s Amazon Web Services. A “private cloud” is a proprietary network or a data center that supplies hosted services to a limited number of other organizations or people. When public cloud resources are used to create a private cloud, the result is called a “virtual private cloud.” Private or public, cloud computing provides easy, scalable access to computing resources and IT services.

Could You Be Using It Someday?

We have entered an era of Things Cloud: “cloud storage,” “cloud computing,” or, just simply “the cloud,” referring to how IT personnel often represent the Internet in their diagrams. Are there opportunities to save money or get improved processes by moving to the cloud? In our analysis, we find that the answer is a qualified “probably so.”

The Cloud

Most business have already encounter the first embodiment of the cloud, “cloud storage,” also know widely as “online storage,” where data is kept not on your local computer but “somewhere” on the Internet, often accessed through a web portal that serves as a user interface for storage and retrieval. Flikr, Gmail, Facebook, and Remote Backup are examples of large implementations of cloud storage. While cloud storage has been around for a while, the cloud-based concept is in the process of evolving into not just providing data storage but operations on that data as well. We’ve entered the age of “cloud computing.”
