Private & Public Cloud
Fast access for secure data transfer and commercial facing data
The majority of businesses are moving to cloud services because of the plethora of advantages this technology provides. Cloud computing technology allows users to access an abundance of resources through private or public networks. Organizations are able to scale their cloud based applications, data and file storage based on their needs. They are also able to determine whether to deploy these applications on public, private, or hybrid clouds or the newest: community cloud.
A public cloud is available to the general public via a service provider who hosts the cloud infrastructure. Amazon AWS, Microsoft, and Goggle are examples of public cloud providers that own and operate their own infrastructures and offer them through the internet. Public cloud users have zero control or visibility on where their infrastructure is located nor how it is configured or secured.
The benefits of a public cloud include cost due to economies of scale as well as the size in comparison to an in-house enterprise cloud. Due to the size of a public cloud, costs are spread across all of the users allowing for a lower cost to each customer. The other advantage of the public cloud’s size is the ability to provide customers with scalability and the efficiency of shared resources, however, this also makes the public cloud more vulnerable versus a private one.
Is a public cloud right for your organization? Ask yourself these questions:
- Is your standardized workload for applications (such as email) used by lots of people?
- Do you need to test and develop an application code?
- Do you need the ability to add compute resources for peak times or need to increase your capacity in increments?
- Do you do collaboration projects?
If you answered “yes” to the majority of these questions, the public cloud may be just right for your business.
A private cloud is a cloud infrastructure solely for one organization. Businesses sometimes opt for private clouds because they are able to have more control of their data security while still having the ability to host their applications in a cloud. Private clouds are able to be hosted internally or externally by a third party.
The two types of private clouds are on premise private clouds and externally hosted private clouds. The on premise private cloud is hosted onsite in the organization’s facility. The business is responsible for all costs relating to the operation of the cloud as well as the equipment required. Entities with on premise private clouds have the most control over the infrastructure security and configuration. Externally hosted private clouds, though only utilized by one business, are hosted by a third party service provider. The third party provider guarantees the utmost in privacy, but the client doesn’t have as much control over the configuration of the infrastructure.

To move your organization over to a private cloud, you will need to reevaluate all of your existing resources and understand what it will take to virtualize your business environment. While private clouds are more costly than public clouds, they provide significantly more security and control.
Is a private cloud right for your organization? Ask yourself these questions:
- Do you need data control but efficiencies of the cloud?
- Do you need consistency across services?
- Do you have more server capacity than your organization currently uses?
- Does your data center need to be more efficient?
- Do you want to provide private cloud services?
If you answered “yes” to the majority of these questions, a private cloud may be just right for your business.
A combination of two or more clouds (private, community, or public) that remain individual units but offer the plusses of multiple deployment models is called a hybrid cloud. Hybrid cloud users can fully depend on third party cloud providers or only partially depend on them. This gives the clients flexibility and the ability to use public cloud resources to handle any unpredicted surges in workload.
Hybrid clouds are on premise and off site. By having your cloud infrastructure spread out in different locations, the IT portion of your business can operation in the most effective environment possible. The disadvantage of a hybrid cloud is maintaining multiple cloud security platforms and being sure all aspects of your business properly communicate amongst one another.
