rivate Cloud: hosted solutions, often managed by a partner/vendor

Public Cloud – multi tenant solutions, managed by the vendor: SAP

Why private cloud?

A key driver for private cloud environments is control – the need to tailor a solution exactly to how a business process is run – because you differentiate with this process.

You may also have specific enterprise or industry needs that need to be accommodated.

SAP C4C solution is hosted on cloud tenant that has many customers. This is called a public tenant —— 多租户。

C4C customers can also go for private purchase edition, which allows them to subscribe for a tenant with no other customer on it —— 独占模式。

SAP C4C production and test tenants are always of separate system. A customer cannot purchase a permanent test tenant for temporary basis. It is recommended only when SDK solution is in use.
