Private Cloud on Dedicated Servers
It’s very important to note that not all clouds are built equally, and neither is necessarily better than one or the other. Really, private and public clouds have features that cater to different types of business needs. But which one is the best fit for your company? Determining the difference between public and private clouds is the first step to choosing the right cloud infrastructure.
Whiteboard Wednesday: Public vs. Private Cloud
Public clouds are often, but not always, owned and operated by third-party service providers. End users benefit because the cost of infrastructure is spread out among all of the users, therefore allowing each individual client to operate on a low-cost, pay as you go pricing model. Additionally, public cloud infrastructures are typically larger in scale than an in-house cloud solution, providing customers with seamless, on-demand scalability.
It is also important to note that with most third-party provider hosted solutions, customers on public clouds share the same infrastructure pool with limited configurations, security protections and availability variances, as these factors are wholly managed and supported by the service provider.
A private cloud is one that is built exclusively for one business or enterprise. They allow the firm to host applications in the cloud, while addressing concerns regarding data security and control, which is often lacking in a public cloud environment. There are two different kinds of private clouds:
- On-Premise Private Cloud: This format, also known as an “internal cloud,” is hosted within an organization’s own data center. It provides a more standardized process and protection, but is often limited in size and scalability. These are usually reserved for companies with extensive IT personnel on staff, and require the company to build, manage, and maintain their own infrastructure. Also, a firm’s IT department would incur the capital and operational costs for the physical resources with this model. If your application requires constant monitoring, complete control and configurability, this option might be best for you.
- Externally-Hosted Private Cloud: This private cloud model is hosted by an external cloud computing provider. The hosting provider builds an exclusive virtual environment and guarantees absolute privacy. For businesses who can’t or wont use a public cloud infrastructure due to the associated risks, this is the way to go.
Hybrid clouds are just that — a blend of both public and private clouds. In a hybrid cloud environment, a company can utilize third-party cloud providers in any capacity, be it total or partial. This increases the flexibility of computing. The hybrid cloud can also provide on-demand scalability, making the hybrid cloud a good option for accommodating unexpected surges in workload.
