SAP is introducing a set of new subscription pricing options for its Hana in-memory cloud computing platform, in a move that falls in step with the pay-as-you-go model common in the cloud computing industry. Customers were already able to bring their existing on-premises Hana in-memory database licenses to SAP's infrastructure service. Now it's possible to buy Hana software via subscription there as well, SAP said Wednesday. A third cloud subscription option adds a series of development tools and services to the infrastructure and Hana software components.
