Cloud primer

An introduction to public cloud services for business audiences.

Our strategy focuses on the use of public cloud services, such as those provided by the hyper-scale cloud providers. 

A simple description of Public cloud services is:

'Public cloud services are internet-based software and compute services that are hosted by third-party providers, that your organisation can self-provision, configure and release on-demand.'

To better understand what we mean by public cloud services, it’s useful to consider some common use cases.

Cloud service Use case
Microsoft Office 365                    Migrating your email service from an on-premises email system to Microsoft Office 365
Google CloudSQL Migrating one of your application databases from an on-premises database server, to a managed database instance on Google Cloud Platform
AWS virtual server instance Migrating a server-based application workload from a server in your datacentre to virtual server instance hosted by Amazon Web Services

Many different types of cloud service are available to be used on-demand with a flexible consumption-based charging model.
