What is a stack? 

A stack (mini, small, medium, or large) provides two environments, one for production and one for testing. Agencies can request one or more additional environments for development/testing purposes. Agencies can also request customised stacks with different attributes and choose optional extras to suit their specific requirements.

Learn more about our new Mini stack offerring. 

All stacks include 24/7 helpdesk with phone and web-based contact. Website uptime is measured against a monthly 99.7% uptime service level agreement.

  • Network bandwidth is shared by all agencies. Each stack contributes to the shared pool. A further quantity of 1280 (national) and 320 (international) kbits is also shared and provided as a baseline.
  • Service cycles. Reports are automatically published to the Service Desk on a regular basis (known as the Service Cycle) and the platform provider will perform software upgrades.
  • Backups cover the production environment only. The UAT (test) environment can be backed up as an optional extra cost.
  • Co-funding pool. Each month, a number of hours are added per stack to a co-funding pool. The Lead Agency consults with Participating Agencies as to how best to use the pool to improve the CWP.
