Whether your organization is a department or agency with the federal, state, or local government, there is a high probability that your critical operations are supported by a legacy mainframe system. If this is the case, you have discovered that maintaining your mainframe applications has become a painful experience and will continue to be so as time marches on.
We, at Astadia, are not recommending that you throw out your mainframe system in total but look to develop a hybrid environment that can modernize your current architecture, modernize mainframe applications, and migrate your data and applications to a more cost-effective platform to support modern applications and your digital transformation.
Regardless of your approach, here are six reasons why your organization needs to modernize mainframe applications.
With all government entities, IT budgets are tight and your mainframe is eating up a large part of it. Some organizations allocate up to 50 percent of their budget to support their legacy infrastructure. Unfortunately, with mainframes, the cost of hardware, software, and maintenance are substantially higher than other compute platforms.
While hardware leasing costs are high, they have remained somewhat static and predictable. However, software licensing costs are volatile and difficult to calculate: you have probably been surprised by your monthly licensing bill on more than one occasion. Mainframe monthly licensing charges can eat up 30 percent of your IT mainframe operating budget. Maintenance costs are also high thanks to the costs associated with additional CPU capacity and memory.
Depending on your modernization approach, your organization can reduce IT costs by up to 80 percent and government entities that have modernized have achieved these kinds of savings. For example, with each agency’s unique modernization approach, a GAO IT Modernization Study reports that :
State and local government departments are also realizing substantial savings with IT modernization. For example, we were able to save the City of Miami over 50 percent, saving at least $900,000 per year.
According to a Forrester study, “mainframe-power organizations have lost 23 percent of their mainframe workforce and only replaced on of every three experts lost. The new development and operations people hired do not have the mainframe experts’ knowledge of the platform’s esoteric differences. They don’t take well to the waterfall-based culture and processes.”
As baby boomers - those who specialized in COBOL, assembly language code, and a waterfall software development methodology - retire, the new generation of IT developers are focusing on cloud platforms and other modern platforms and tools.
For example, in the GAO IT modernization study mentioned earlier, “agencies have had difficulty finding employees with such knowledge and may have to pay a premium to hire specialized staff or contractors.” The study goes on to disclose that the Social Security Administration needed to rehire retired employees to maintain its mainframe system and the IRS was experiencing staff shortages with skills to support legacy-based tax processing systems.
A shortage of mainframe-savvy development and operations personnel will put your mainframe data and applications at risk from both a performance and security perspective. Limited COBOL talent has driven many organizations to modernize.
Using a mainframe environment for the modern applications that support your digital transformation initiatives will increase your IT costs as you add CPU and memory capacity. Worse yet, a mainframe’s hard coding of business rules means that these applications are not easily changed. And, mainframe environments cannot easily support modern technologies that have been enabled by cloud services such as Machine Learning, Advanced Analytics, and Artificial Intelligence or modern development approaches like DevOps.
As stated in a CIO article, “Under the covers, modernizing is about creating an integrated application, infrastructure, and business process stack that is no longer bolted to the proverbial data center floor…That transformation journey will involve rewriting some applications, creating brand new ones from scratch, sunsetting others and, in some cases, leaving legacy applications precisely the way they are, but in a more agile operating environment..”
With IT modernization, your organization can “gain agility with reduced development cycles via continuous integration and continuous delivery (CI/CD), and virtually unlimited infrastructure resources consumed on demand.”
According to the GAO study, many government legacy systems “may operate with known security vulnerabilities that are either technically difficult or prohibitively expensive to address.” Worse yet, many government departments and agencies are running operating systems and applications that are no longer supported. This put the personal records and financial information of millions of federal study aid applicants at risk.
The first rule in maintaining the security of your operating systems and applications is to immediately install any software updates. These updates patch the security vulnerabilities and ensure that your systems and data are protected from cyber-security attacks, including ransomware. Unfortunately, if your operating system and/or applications are no longer supported, you won’t be getting any updates.
The costs of implementing and maintaining an on-premises disaster recovery (DR) strategy in support of your mainframe environment is not only costly but complicated. If a department or agency spends $100,000 maintaining their mainframe environment, it will cost another $100,000 to maintain an on-premises, high-availability system. DR can be difficult and if multiple products are used for recovery, it makes the process more complex. Systems dependencies are difficult to map, DR exercises and testing can be time consuming, and the plethora of DR products make for more complicated training of IT staff – all increasing the risk of failure.
Unlike commodity servers and the cloud, mainframe operating systems and applications cannot be easily moved to non-mainframe systems. As a result, the backup and DR process can be complicated requiring you to routinely offload data, create backup tapes to store offsite, replicate data, implement a virtualization strategy, and spread out your mainframe resources across your organization.
With IT modernization, you can implement cloud backup and disaster recovery, which are cost-effective, convenient, and easy:
Many federal and state departments and agencies use IT shared services. With this model, the cost of the mainframe environment is shared by those internal customers who rely on the mainframe system(s). Shared services is designed to lower costs, achieve greater efficiencies across the organization, improve employee productivity, and provide your team with access to top talent and best practices.
While this all sounds great, keep in mind that as other departments and agencies who share these IT services modernize their IT infrastractures, they will no longer rely on shared services. As a result, the costs of an IT shared environment will be spread out over the remaining clients. This means that if you are slow to modernize, you can expect your IT costs to increase.
For example, if it costs $100,000 a month to maintain a shared services environment and there are five clients sharing the service, each client pays $20,000. However, if three of these clients modernize and move away from shared services, the $100,000 a month maintenance fee will be shared by the remaining two clients, who will pay $50,000 a month.
When you look at all the reasons why you should modernize your mainframe environment and mainframe applications, there are no reasons left NOT to modernize. Yes, there are risks associated with mainframe modernization, but these risks can be eliminated by choosing an IT modernization partner that has “been there and done that” many times and has worked with a spectrum of government departments and agencies. Yes, IT modernization costs money, but the savings can deliver a respectable return on investment (ROI) in addition to the other key benefits that we have discussed here.
Many of the software engineers who have maintained mainframe COBOL applications over the years have recently retired.

As technology advances, mainframe organizations are increasingly pressed to transition to more modern platforms. Here are some of the most common misconceptions that hinder their mainframe modernization journey.
The cost of not modernizing mainframe systems is generally far greater than the time, effort, and money required to make the transition. Here's why.
As mainframes host mission-critical applications, it's essential to ensure that the modernization process is accurate and causes minimal disruption to business operations. This is where automated migration and testing tools come in.
