Health Insurer Modernizes Mainframe Testing with Zowe-Powered CI/CD
Challenge
A global banking leader needed to increase mainframe system capacity while adhering to a strict IT budget.
After evaluating proposals from several vendors, including the largest in the industry, they chose to partner with CPT Global to:
- Reduce MIPS utilization
- Lower IT costs
- Improve system performance
CPT Global’s Actions
A major vendor proposed a like-for-like hardware upgrade, which would have added 750 MIPS—significantly exceeding the bank's actual requirements.
CPT Global conducted a thorough analysis of z16 capacity options. Our analysis revealed that, due to CPT's mainframe optimization work over the previous two years (MIPS reduction and WLM configuration changes), the bank could achieve its goals by simply reducing the proposed configuration by two CPUs.
The reduction in engines plus the avoidance of capacity increases in the prior two years saved the company millions in both realized savings and costs avoided.
Results
- $1.5 million saved annually in software costs.
- $140,000 saved per mainframe by avoiding unnecessary zIIPs.
- Maintained workload stability while preparing for a seamless 2024 workload refresh.
By working with CPT Global, the bank avoided costly hardware upgrades, saving millions while meeting their capacity requirements.
