How many clouds do you need?
Traditionally, enterprise-owned data centres were the predominant provider of an organisation’s services. These can be considered to be “private clouds”, the hardware and services and their security being under the organisation’s control. On the other side of the spectrum, resources and services can be provided via a third party provider – as a ‘public cloud’ – which are accessed by multiple organisations. Without the need to source and implement new physical systems, or (in many cases) application platforms, organisations can gain significant time savings in the system development lifecycle by deploying to public clouds.
