5 Legacy Technologies Still in High Demand Today

Computing technology is a long way evolved from its origins in the mid-1900s. Yet a lot of those original tools are still carrying the weight of today’s IT infrastructure. Sharon Florentine, writing for, explains why five of these bedrock technologies still matter to the IT pro:

While technology continues to evolve and new languages and technologies like Ruby, Hadoop and cloud containers dominate headlines, proven legacy solutions continue to work quietly behind the scenes, powering much of the digital world.

5 Fabulous Foundations

  1. COBOL
  2. Mainframes
  3. C
  4. Fortran
  5. Java (semi-legacy)

One of the most secure technologies of today, COBOL is a great language for simultaneous processing of large-summed transactions. It has a penchant for exceptionally large numbers that require exact computation, and is still useful for industries that require a large degree of stability – airlines, finance, insurance, and others.

On the hardware side of things, mainframes maintain some popularity due to their ability to run reliably, sometimes uninterrupted for decades. Like the COBOL language, they have a natural affinity for reliably processing large sums of data and large numbers. They remain the back-end standby of most financial, logistics, and manufacturing operations.

C, being a “root language” like Latin is to French, Spanish, and Italian, lends itself to newer languages like Java, PHP, and C++. Operating and embedded systems rely on it, and beyond programming it is used in some software applications, as well as for the Unix operating system. Fortran meanwhile, a truncated version of the phrase “Formula Translating,” was created to speed up scientific and engineering applications. It is the Latin mother language of high-performance, scientific computing, and is still in high demand among engineers and researchers.

This last technology may not strike you as being “legacy,” but consider that it is now two decades old. Java remains one of the most popular languages for programming, especially for client-server web applications.
