Cloud computing continues to gain attention and momentum as companies learn about and experience the benefits of Internet-based solutions. The use of cloud solutions is increasing exponentially while traditional data center computing models are declining for the first time.
Virtualization via cloud computing creates business efficiencies, adds flexibility, increases server capacity, and provides companies with the benefits of distributed data. The positives of the cloud are universal and the cloud computing market has evolved to support four primary models for cloud deployments. Each model has its own benefits and drawbacks that must be weighed when making a cloud choice.
Keep It In-House
The idea of “the cloud” gives rise to images of equipment housed and data stored in some vague place. In reality, the cloud can reside within the physical confines of a company’s premises or at a private data center.
Private cloud solutions allow companies to provide the benefits of the cloud to employees while maintaining tight control over the network equipment and applications available to them. Companies with the resources to deploy the necessary equipment and maintain it over the life of the network may gravitate toward this option, especially if in-house control of assets is a primary concern.
Some companies, particularly smaller organizations or companies that only need the cloud for a limited time, may not have the resources or time to deploy and maintain an in-house private cloud network. For these companies, the ability to flip a switch and activate cloud services without the startup cost and work is attractive.
Public cloud offerings hosted and maintained by a third-party provider might be an ideal choice for this segment. The provider services many end users with the same resources, thereby aggregating the costs among those users and allowing each to pay only for what they need, when they need it.
The Best of Both Worlds
Many companies want the simplicity, flexibility, and scalability offered by public cloud solutions, but they are hesitant to cede such a high level of control to a third party. Enter the hybrid solution, which gives companies the benefits of both models.
Using a hybrid approach, a company can still tap the resources and benefits built into the public cloud model while retaining some control within the company. This model allows a company to adjust the network to meet its changing needs. Companies can also use a hybrid approach to offload traffic during peak usage on the private network temporarily to the public cloud.
A relatively new concept, the community cloud model allows equipment to be hosted either privately or publicly. Companies may use this model to test public-cloud products and features. Within this model, servers do not have to be dedicated to specific users, but can be logically segmented among several end users while maintaining the security of a dedicated environment.
Making the Choice
Choosing the right model will depend on each company’s business environment and needs as well as the type of data that will be hosted on the network. A careful evaluation of the company’s needs and how each cloud model might fulfill those needs is crucial when deciding how to deploy cloud services.
