===IBM Db2 Standard Edition===
The Db2 Standard Edition is available as a perpetual software license for production and non-production use for up to 16 processor cores and 128 GB RAM with IBM support. For production use, Db2 Standard Edition can be licensed based on a Virtual Processor Core metric, wherein it is licensed by the total count of processor cores in a non-partitioned physical server, or virtual cores assigned to a virtual server. For non-production use, Db2 Standard Edition can be licensed based on the total count of authorized users.

===IBM Db2 Advanced Edition===
The Db2 Advanced Edition is available only as a component of the IBM Hybrid Data Management Platform (HDMP). Within HDMP, Db2 is available both as a perpetual software license AND a monthly subscription for unrestricted production and non-production use with premium IBM support. For both HDMP perpetual license and subscription offerings, FlexPoints need to be bought. FlexPoints are generic licensing credits that can be used to deploy any Db2-family software product or cloud service offering.
