In my last two posts, I explained ways of reducing MIPS usage and associated costs. In this post, I’ll use a survey to highlight how important MIPS is to legacy modernization and how reducing MIPS usage can lead to a healthier relationship between mainframes and new technologies.
Mainframes have proven to be secure, fast, reliable processing platforms, but they tend to be complex. Despite their growing costs and complexity, many companies are still living with mainframes and attempting to marry them to the newer technologies.
Compuware, the world’s leading mainframe software company, last year released the findings from a survey of 350 CIOs. In asking questions about the impact of new technologies and trends on the mainframe application environment, it uncovered a profound disconnect between the importance of the mainframe to the business and the actions currently taken to protect their investments in the platform.
Distributed applications are not only forcing the mainframe to work harder due to the surge in demand, they are pressuring it to deliver at even faster speeds. The younger generations of consumers expect applications to launch in a few seconds. As a result, CIOs and CFOs feel constant pressure to deliver, while keeping costs low. Here are some of the statistics from the survey:
Mainframe usage fees make up a significant component in the cost of ownership of an organization’s IT budget. According to the US Department of Defense, the average mainframe per-hour spend is rising year-over-year, due to the fact that MIPS consumption is steadily on the rise. Furthermore, IT industry analysts estimate that most large organizations using mainframes should expect their systems’ CPU resource consumption to increase by 15% to 20% annually. Hence, addressing MIPS becomes a top priority.
Mainframes weren’t designed to interact with customer-facing applications, and interfacing with mobile applications could never have been imagined. Now that there is a forced marriage between the two generations, maintaining a healthy relation between them has become a costly affair.
However, organizations can significantly reduce MIPS consumption by identifying high consumption workloads within existing environment and offloading these workloads onto less costly systems. Re-hosting high MIPS-consuming workloads is a relatively low-cost option because it reuses the same code base with the original business logic from the legacy system with a newer environment. That decreases TCO while taking the enterprise a step closer to the modern world.
