Mainframe migrationJuly 8, 2020
About a decade ago, the estimated mainframe install base was in excess of 30,000 installations. Today, there are less than 10,000 left. Some of this decline happened as a result of consolidation; some because of package replacement. A significant number (in the 1000’s) are gone because of mainframe migration effort. All moved because of the same underlying issues: current high cost or forced upgrades, technology lock-in, de-support risk and last but not least, skills retirement. According to leading analysts like Gartner and Forrester, tens of thousands of Cobol programmers are retiring every day continuing beyond 2019.
If your enterprise is like most, you have a variety of platforms that span decades of IT innovation. These may include IBM mainframes, Tandem, Bull and Unisys, to name a few. Furthermore, you may run a legacy database, such as DB2, IMS/DB, IDMS, or Adabas, with applications written in COBOL, PL/I, CICS and a 4GL language such as Natural or CA Gen. Holding on to this environment is not only costly but it also limits you from innovating and growing your business.
Mainframe migration gives you the ability to:
- reduce the TCO of your business-critical applications;
- invest in business growth;
- innovate with tools and technologies that increase your agility;
- take advantage of new technologies like Mobility and Cloud.
