Private clouds are loosely defined as cloud environments solely dedicated to a single end user or group, where the environment usually runs behind that user or group’s firewall. All clouds become private clouds when the underlying IT infrastructure is dedicated to a single customer with completely isolated access.
But private clouds no longer have to be sourced from on-premise IT infrastructure. Organizations are now building private clouds on rented, vendor-owned data centers located off-premises, which makes any location and ownership rules obsolete. This has also led to a number of private cloud subtypes, including:
Managed private clouds
Customers create and use a private cloud that’s deployed, configured, and managed by a third-party vendor. Managed private clouds are a cloud delivery option that helps enterprises with understaffed or underskilled IT teams provide better private cloud services and infrastructure.
A cloud within another cloud. You can have a dedicated cloud on a public cloud or on a private cloud. For example, an accounting department could have its own dedicated cloud within the organization’s private cloud.
