 ### Infinispan (recommended)
 
 Infinispan is a storage solution that can also run on the z/OS platform. It can store data structures in key-value pairs, has high-availability support, and is highly performant.

 ### VSAM
 
 VSAM can be used to organize records into four types of data sets: key-sequenced, entry-sequenced, linear, or relative record. Use VSAM as the storage solution for production. VSAM is used primarily for applications and is not used for source programs, JCL, or executable modules. ISPF cannot be used to display or edit VSAM files.
