An Overview of Legacy Software and Legacy Systems

If you are interested in learning more about legacy software and legacy systems, this post provides a brief overview. If you’d like to discuss options for your legacy system, please contact us.

What is legacy software?

Legacy software is software that has been around a long time and still fulfills a business need. It is mission critical and tied to a particular version of an operating system or hardware model (vendor lock-in) that has gone end-of-life. Generally the lifespan of the hardware is shorter than that of the software. As time goes on, the hardware gets harder to maintain but is kept because it is installed and (for now) working and has proven too complex and/or expensive to replace

What are legacy systems?

Legacy systems include both the legacy software and the legacy hardware. Here at Stromasys, we virtualize the legacy hardware; we make no changes to the business software. Since the only change to the legacy system is replacement of the hardware with an industry-standard server, the arduous process of software certification does not have to be repeated.

Who has legacy systems?

Legacy systems are everywhere; banks, energy companies (including nuclear plants), manufacturing of all types (process control), the defense industry, transportation, hospitals, insurance, and more.  At Stromasys, we work with organizations of all sizes and across just about every vertical with production or business critical environments.

Is Charon an option for your legacy system(s)?

Charon is a strong option for companies who still need their legacy applications and cannot take the risk of rewriting the business logic in a software migration. If you are experiencing pains of failing PDP-11, VAX, Alpha, HP 3000, or SPARC hardware and want to take preventive measures, contact us to learn more about which customized Charon solution is right for your organization.
