Public cloud versus other types of cloud

Scale and secure NZ government information by using resources that are set up, owned and maintained by a third-party provider.

Cloud-based tools and applications

A shared pool of computing resources that is often delivered as infrastructure tools and web applications — these include:

  • servers
  • data storage
  • service management
  • networking
  • platforms
  • analytics and intelligence
  • mobile applications.

Cloud services are information systems

Public cloud services are like other information technology systems — they are sets of computing components that work together to store, process and send information.

Specific types of cloud services

Cloud services can be based in private or public models, or variations of these, such as community and hybrid.

Private cloud services

Your organisation sets up, owns and maintains its computing resources, sharing its infrastructure and applications through its private network.

Public cloud services

Your organisation accesses, through the internet, the computing resources that a third-party provider sets up, owns and maintains.

Benefits of using public cloud services

Cabinet requirement — check if public cloud services are right for your information

Cloud First policy

Other types of cloud services

Private, community, hybrid and multi-cloud models offer different solutions and create varied complexities in managing them.

Despite public cloud’s benefits, government organisations can use the other types of cloud. It might make sense to use them for certain business needs.
