Comparing Different Cloud Architecture Types
By Michelle Ziperstein
If you are new to the idea of cloud computing, or if you are considering a different
type of cloud architecture, then this article is for you. By now, most people are familiar
with the concept of a cloud-based data center that hosts files and rents out computing power
to businesses. There is, however, a number of possible cloud types that may be the right choice
for a company, depending on its profile.
This article will discuss the three cloud architecture types - public, private, and hybrid,
the differences among them, and situations where each works best.
The Public Cloud
In the public cloud model, you are provided with secure virtualized hosting via a server
that scales to meet all of your business's growth demands. Like any type of cloud computing,
one benefit of the public cloud is that your company no longer needs to build and maintain
its own network, nor does it have to employ staff to do so, which translates into huge cost
savings for many companies. The public cloud has other benefits as well, such as:
• Pay by the hour pricing
• API access, which allows you to spin up and kill servers as needed
• Ease of deployment - it's all done through the provider's website
However, you do have to be careful, because security issues and fraud due to public access
may cause problems from time to time.
The Private Cloud
In the private cloud, each customer is assigned a unique, secure, and dedicated computing
environment completely firewalled off from the outside world. Some benefits of private cloud
• Increased security
• You own and control your own space
• You can still easily scale your business without exponentially increasing IT costs
The private cloud does reduce IT costs, but it may not do so as well as the public cloud.
The Hybrid Cloud
What a hybrid cloud actually is depends on the needs of your business and the way you
discuss them with your prospective cloud hosting service. In hybrid cloud computing, you work
with your host to develop the most effective solution for your business. Benefits of the hybrid
• Solutions customized to exactly what you need
• Reduced costs versus your own internal network
• Fully scalable to any size
To determine which cloud you should use, you really have to engage in regular discussions
with your IT team and identify your business's top needs. Once you identify those needs, then
you can choose the cloud computing solution and potential data center service that works best
for you and your company. Come to our website to learn more about what data centers and cloud
