The difference between private, public and hybrid cloud
When you look into hosting and infrastructure services, you’ll come across three types of cloud computing:
• Private
• Public
• Hybrid
These three have different levels of management and security. So before you discuss the pros and cons of them with a service provider, you need a working knowledge of each one. This way, your cloud can match your data and business needs as closely and successfully as possible.
Private cloud
With a private cloud, the infrastructure and services are on a private network. No one else has access.
As a result, a private cloud gives you the best level of management and security. You won’t maximise your cost savings, however, because you have to buy and maintain the infrastructure and software.
You should consider a private cloud when:
• You run a business where compliance with laws on data privacy and security is vital
• Your applications and data make up most of your business
• You have a business capable of running a cloud data centre on its own
Public cloud
A public cloud is an off-site service available to your business over the Internet. You share resources. And because of this, you can achieve high levels of efficiency. But public clouds are potentially more vulnerable to security breaches than private clouds.
A public cloud is a good option when:
• Many people use your standard applications
• Your company is working alongside other businesses
• You require extra capacity at short notice
• Your business uses Software as a Service (SaaS) applications from a supplier which has tight security
• You want to develop and run tests on application code
Please note: the distinction between public and private clouds is not always clear. Companies sometimes offer public versions of their private clouds and vice versa.
Hybrid cloud
A hybrid cloud mixes private and public cloud services. When you use a hybrid cloud, you can place each part of your business in the most efficient and cost-effective private or public service.
A hybrid cloud is useful when your business offers bespoke services for a range of clients. You can keep data secure in a private cloud but work with the clients in a public cloud.
The hybrid approach can also be best when you have worries about security but want a public SaaS application. Your SaaS supplier can make a private cloud for you, and increase security further with a virtual private network.
