Onboarding and offboarding

Onboarding and offboarding
Getting started Our services are simple to consume requiring only a browser (and in the case of VMware vCloud a small plug in to be installed). New customers are asked to provide us with a list of authorised contacts and permission levels with whom we can engage and those nominated individuals are provided with documentation and if need be training on how to contact us for support, how to access the ticketing and monitoring portals and how to use VMware vCloud

For all customers provide documentation for using the Carrenza IaaS. In addition to the detailed documentation, Carrenza can run individual and group training sessions for using these clouds. The sessions are either delivered via WebEx or face-to-face.

At a base level Carrenza do not charge customers to on-board and off-board from the Carrenza IaaS. However, should an organisation require additional support as part of the on-boarding process, such as project management, detailed technical design, etc, then Carrenza might need to charge for this. This will either be charged as time and materials (T&M) or as a pre-agreed flat service fee.
