Public Cloud

The cloud holds a lot of promise and a lot of promises. Low cost… Rapid provisioning… Elasticity… Highly extensible architectures… Transforming IT into a utility… reducing capex IT spend…

But not all clouds are created equal, even by the same provider. So what are the differences between public, private and hybrid clouds and which is right for you?

Public Cloud

Public cloud offers the biggest opportunity for cost savings. IT becomes a utility supplied by your cloud provider; your business no longer incurs hardware or maintenance costs and you pay only for what you use. Economies of scale enable the cloud provider to provide these compute resources often at a much lower price than the cost of hosting them in-house.

Public cloud offers the greatest potential for elasticity. To achieve this, your cloud provider needs to give you the tools to rapidly (or automatically) provision and decommission compute resources so they ramp up and down in line with fluctuating business demands. Because you’re paying only for what you use, this maximises cost savings. You also shift risk to your cloud provider, which is locked into agreed SLAs.
