As much as enterprise IT evolves, we’re left running old hardware and software for many reasons. Perhaps there’s a regulatory requirement to keep data for as long as possible; perhaps there’s a dependency on code that remains reliable and supported even after decades. Whatever the reason, we may need to work with that system and that data as part of a newer platform.
One platform that’s not going away is the mainframe, especially in government and finance. A lot of critical data and software runs on those systems, and they’re not as outdated as we might think, running hypervisors and multiple operating systems—including up-to-date Linux distributions.
