  28. 28. 29 Container Pricing – 3 solutions announced with z14 29 The Application Development and Test Solution will provide highly competitive stand-alone pricing for z/OS based development and test workloads. Modern DevOps tooling can be optionally added at uniquely discounted prices. The New Application Solution will provide a highly competitive stand-alone priced offering for new z/OS applications, such as CICS TS or WebSphere applications, that are not currently running on any Z platform server. This is the strategic replacement for the current zCAP and IWP priced offerings. The Payments Solution will provide a ‘per payment’ pricing option for IBM Financial Transaction Manager for z/OS deployments. This new offering directly ties operational cost to business value by basing the price on the number of payments processed, rather than capacity used to process them.

  49. 49. Trademarks 50IBM Z / © 2017 IBM Corporation Notes: Performance is in Internal Throughput Rate (ITR) ratio based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput that any user will experience will vary depending upon considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve throughput improvements equivalent to the performance ratios stated here. IBM hardware products are manufactured from new parts, or new and serviceable used parts. Regardless, our warranty terms apply. All customer examples cited or described in this presentation are presented as illustrations of the manner in which some customers have used IBM products and the results they may have achieved. Actual environmental costs and performance characteristics will vary depending on individual customer configurations and conditions. This publication was produced in the United States.

No other workload processing is authorized for execution on an SE. IBM offers SE at a lower price than General Processors/Central Processors because customers are authorized to use SEs only to process certain types and/or amounts of workloads as specified by IBM in the AUT. * Registered trademarks of IBM Corporation The following are trademarks of the International Business Machines Corporation in the United States and/or other countries.
