Cloud Computing Models Demystified

For those of you considering moving your business across to a cloud based storage system, it’s important to know the difference between private and public cloud storage models. As each option has its own range of unique features, it is recommended that you weigh up the pros and cons before deciding which platform is right for you.

In a nutshell, a private cloud solution means that your business maintains a distinct and secure cloud-based environment within which only your business can operate. For a public cloud however, you’ll utilise shared physical resources and infrastructure that multiple organisations have access to. Depending on which model you choose within the public cloud (there are three main options to choose from), you’ll also assume a different level of responsibility.

With a number of public cloud models to choose from, it is up to you to determine which one will best suit your business needs. The first public cloud option available is the ‘Infrastructure as a Service’ (IaaS) model. Dividing responsibility about 50/50 between yourself and the cloud provider, this is a good option for those wanting to take their first tentative step towards cloud computing.

As you move to the ‘Platform as a Service’ (PaaS) model, your cloud provider should be responsible for about 70-80% of your needs before reaching full responsibility under a ‘Software As A Service’ (SAAS) arrangement. It is prudent to remember however that all security processes and workflows will generally remain your responsibility. This is common no matter what model you choose.

The final hard and fast rule for cloud computing? That’d be that there is no hard and fast rule. As with most services, there are vast differences in what is included from vendor to vendor. Make sure you do your homework so you know exactly who is doing what (on both sides), and to ensure that you get the best service for your business needs.
