According to the HPE Edge-to-Cloud Adoption Framework, page 5, a traditional solution is a cloud deployment model where the cloud infrastructure is provisioned for exclusive use by a single organization comprising multiple consumers (e.g., business units). It may be owned, managed, and operated by the organization, a third party, or somecombination of them, and it may exist on or off premises. A traditional solution offers the organization more control, security, and customization over their cloud resources, but it also requires more investment, maintenance, and expertise.
A hybrid solution is a cloud deployment model where the cloud infrastructure is a composition of two or more distinct cloud infrastructures (private, community, or public) that remain unique entities, but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load balancing between clouds). A hybrid solution offers the consumers more choice, agility, and innovation over their cloud resources, but it also requires more integration, management, and complexity.
Based on these definitions, the following use cases are hybrid solutions:
An on-premises database, emerging applications, storage as a service with VMs, or container environments and cloud back up. = Hybrid solution. This use case involves a combination of on-premises and cloud resources, and requires data and application portability between them.
A small private cloud for productivity and collaboration with public cloud disaster recovery or testing and development. = Hybrid solution. This use case involves a combination of private and public cloud resources, and requires data and application portability between them.
The following use cases are traditional solutions:
A small deployment in an office consolidating a small number of applications but limited SLA requirements. = Traditional solution. This use case involves a single organization using a cloud infrastructure for exclusive use, and does not require data and application portability to other clouds.
Large Object-Store performance database and online transaction processing (OLTP) without external connectivity. = Traditional solution. This use case involves a single organization using a cloud infrastructure for exclusive use, and does not require data and application portability to other clouds
