A recent study by IDG Enterprise reported that about one-third of IT budgets are allocated to cloud solutions. With cloud adoption growing exponentially, and considering all of the advantages that cloud computer has to offer, it is important to learn more about where our data stored "in the cloud" is actually going. Part of this learning process is getting educated about the different kinds of cloud infrastructures and their applications. There are actually four types of cloud infrastructures: private, public, hybrid and community.

1. Private Cloud
A private cloud is a cloud infrastructure that is dedicated to a single organization or enterprise. It can be hosted and managed internally or externally, such as in Meridian’s secure data center in Ashburn, Va.
Advantages of a private cloud include:
- tight security controls
- scale-up potential
2. Public Cloud
The public cloud infrastructure is is generally provided over the Internet through a cloud services provider. Some of the larger public cloud providers include:
Advantage: start-up costs for public clouds are usually less than those required for private clouds.
Disadvantages: public clouds offer less privacy and security than private clouds.
3. Community Clouds
Community cloud infrastructures can be shared by enterprises with common concerns. These clouds are typically used by :
Two or more of these types of organizations with similar security, legal and compliance issues may share a community cloud.
4. The Hybrid Cloud
Combine any of the above clouds and bind them together to expand deployment options. This can allow for “cloud bursting,” in which an application normally runs in a private cloud, but “bursts” to a public cloud to meet increased needs, in an on-demand basis.
Advantages: hybrid clouds allow you to keep your private cloud, while also adding the additional storage and cost-effectiveness of a public cloud when you need it.
For a real life example of how the NFL benefitted from the use of a hybrid cloud check out this article.
Whether your organization is large or small, private or public, there is a cloud solution to fit your needs. Regardless of whether your main concern when it comes to cloud computing is privacy or cost-effectiveness, understanding which cloud services are available is the first step in selecting a cloud solution that best fits your organization.
In addition to selecting the right kind of cloud services for your organization, you should also make sure you are selecting the right cloud services provider.
