The hybrid cloud model combines both cloud and on-premises infrastructures, allowing the company to keep their legacy applications on existing servers while leveraging cloud services for other operations. This provides the flexibility to use cloud resources where beneficial while maintaining certain applications on-premises.

Migrating to a public cloud service typically involves moving applications off-premises, which conflicts with the need to keep legacy applications on their existing servers.

Maintaining an on-premises infrastructure alone would not provide the scalability and cost-saving benefits of cloud computing.

Implementing a private cloud hosted by a third party also involves moving applications off-premises and may not address licensing constraints associated with the legacy systems.
