6 reasons why your mainframe is expensive and what could be done about it?

Mainframes are perceived to be expensive, and there are several reasons why:

Robustness and reliability: Mainframes are designed to deliver high levels of reliability, availability, and fault tolerance. They are built with redundant components, such as processors, memory, power supplies, and storage, which ensure continuous operation and minimize the risk of system failures. The cost of developing and manufacturing such robust systems contributes to their high price.
Scalability: Mainframes are capable of handling massive workloads and scaling up to support thousands of users and transactions simultaneously. This scalability requires advanced hardware and software architecture, resulting in increased costs.
High performance: Mainframes are engineered to provide exceptional processing power and throughput. They incorporate specialized processors, high-speed interconnects, and sophisticated memory management techniques to deliver optimal performance for critical business applications. The cutting-edge technology employed in mainframes comes at a premium price.
Security: Mainframes are known for their robust security features, including advanced encryption, access controls, and auditing mechanisms. They are designed to protect sensitive and confidential data from unauthorized access, tampering, and breaches. The stringent security requirements and the investment in security infrastructure contribute to the higher cost of mainframes.
Long lifespan: Mainframes have a long lifespan compared to other computing platforms. Many organizations rely on mainframes for mission-critical operations, and they often run for decades. The longevity of mainframes necessitates ongoing support, maintenance, and compatibility with legacy systems, which can increase the overall cost of ownership.
Specialized software and skills: Mainframes typically require specialized software and tools to run applications and manage system resources. The development and licensing costs for mainframe-specific software can be significant. Additionally, acquiring and retaining skilled mainframe professionals who possess the expertise to operate and maintain these complex systems can also contribute to the cost.

It's worth noting that while mainframes have high upfront costs, they often provide a favorable total cost of ownership (TCO) over the long term due to their efficiency, reliability, and consolidation of workloads. Organizations that heavily rely on large-scale transaction processing, data-intensive applications, or require robust security often find mainframes to be cost-effective.

Investing in a quality mainframe system brings significant value to many top enterprises, and yet it can still be difficult to stomach. How can mainframe managers work to reduce ongoing mainframe costs without complicating the value z/OS systems bring to their company?

Reducing mainframe costs can be a complex process, but here are several strategies that organizations often employ:

Optimization of workloads: Analyze and optimize the workloads running on the mainframe. Identify inefficient or unused applications, processes, or resources and eliminate or consolidate them. This can help reduce resource consumption and improve overall efficiency.
Capacity planning: Conduct thorough capacity planning to ensure that the mainframe resources are utilized optimally. By accurately forecasting future requirements, organizations can avoid overprovisioning and unnecessary costs associated with excessive hardware or software licenses.
Virtualization and consolidation: Leverage virtualization technologies to consolidate multiple applications and workloads onto a single mainframe. This approach can reduce hardware and software costs, as well as streamline maintenance and management efforts.
Software license optimization: Review software licensing agreements and ensure compliance with the terms and conditions. Eliminate unused or redundant software licenses and negotiate better pricing based on actual usage.
It is in the best interest of IBM to offer z/OS discounts, because it promotes user satisfaction and retention. But even though discount opportunities exist in the world of mainframe cost control, users don’t always know where to look. It’s not uncommon for z/OS users to over-pay simply because they don’t know how to bargain hunt.
For example, contracts based on Advanced Workload License Charges (AWLC) are designed to reduce mainframe costs by aligning costs with MSU consumption. This pricing metric — a “pay for what you use” model — allows users to pay for key software at the LPAR level. This degree of specificity allows users to regulate costs with improved efficiency.
However, this pricing metric is not a simple “set it and forget it” option. Without ongoing optimization, users stand to take on an even greater financial burden than when they started. The AWLC pricing usually comes with an Enterprise License Agreement (ELA) contract that requires users to commit to an annual MSU consumption limit, and if this cap is exceeded users are penalized with a large bill at the end of the year. Whether due to penalty fees or overcompensating with excess consumption commitments, many users overpay for mainframe contracts.
Be sure to review your monthly report, identify common workloads that might be subject to discounts, and adjust accordingly. But don’t stop there — practice regular system optimization to ensure your mainframe needs and contract requirements continue to align.
Offloading non-critical workloads: Identify non-critical or less time-sensitive workloads that can be offloaded from the mainframe to alternative platforms or cloud-based solutions. This can help reduce mainframe resource consumption and associated costs.
Modernization and migration: Assess the feasibility of modernizing or migrating certain applications or functionalities to more cost-effective platforms, such as distributed systems or cloud environments. This approach can potentially reduce mainframe dependency and associated costs in the long run.
Training and skills development: Invest in training programs for mainframe professionals to enhance their skills and expertise. Well-trained staff can optimize mainframe operations, troubleshoot issues more efficiently, and maximize resource utilization, thereby reducing costs.
Vendor negotiations: Engage in negotiations with mainframe vendors to explore potential cost savings. This could involve renegotiating maintenance contracts, seeking discounts on hardware or software purchases, or exploring alternative pricing models.
Monitoring and performance tuning: Implement robust monitoring and performance tuning practices to identify bottlenecks, optimize resource utilization, and improve overall system efficiency. This can lead to cost savings by ensuring optimal use of mainframe resources.
Cloud and hybrid solutions: Consider adopting cloud or hybrid solutions that combine mainframe capabilities with cloud-based services. This approach allows for more flexible and scalable resource allocation, potentially reducing mainframe costs while leveraging the benefits of cloud computing.

It's important to note that each organization's mainframe environment is unique, so it's crucial to assess the specific needs, priorities, and constraints before implementing cost reduction strategies. Working closely with mainframe experts, vendors, and stakeholders can help identify the most effective approaches for cost optimization.
