2013 brought about even higher adoption of cloud based services across nearly every technology industry. From accounting software to streaming music to video conferencing and collaboration, the cloud has clearly come of age. What can be confusing about cloud-based services is the different ways they are deployed both internally and externally. The three types of cloud deployments are public clouds, private clouds and hybrid clouds. To help you understand the differences, here are the definitions and examples of the three types:
Public Clouds provide services over the public Internet. These types of clouds provide access to a significant amount of shared resources and can more easily provide scalable capacity. As an example, if a website is having a special event and expects a spike in traffic, public clouds can be configured to provide that needed capacity at the right time and then be scaled back. Additionally, public clouds make it easy to collaborate with other people and organizations, as the service is accessible to all.
Private clouds provide services over a private network. In these deployments, organizations must make the investment in the infrastructure and technology, negating a significant portion of the cost savings associated with public cloud based services. Private clouds are preferred when organizations want complete control over security and customization.
Examples of private clouds include financial organizations that provide secure systems to their employees in order to maintain compliance with federal privacy regulations.
Hybrid clouds deliver services via a combination of public and private clouds. There are a number of reasons an organization would want to create an environment like this. For example, a company might want to leverage a public cloud service (in this case let’s use Rackspace’s Public Cloud Storage service as an example) for older archived data while building and maintaining a private cloud for more timely and current business data. A secure VPN connection could then be established to allow data to move from the internal cloud to the archive in the public cloud at the appropriate time.
The cloud has come of age, as has its ability to be molded to fit the particular needs of many different types of organization. While it can be somewhat confusing to understand all of the deployment models, one thing is for certain: the cloud has truly redefined the way technology is deployed and consumed.
