To Modernize Legacy Systems, Cloud Offers an Optimal Path


In many cases, legacy modernization requires a new style of development that encompasses new priorities for the full enterprise technology stack, from hardware and data centers up through the OS, user experience and mobile interface.

I recently wrote in my Software Intelligence primer that the goal of IT modernization must be to create new business value from new and/or existing applications or systems. This brings software quality and security to the front and center of any modernization effort.

For the College Board, IT modernization meant re-architecting some of their applications for a cloud migration. As part of this effort, the College Board’s VP and chief data officer, Jeff Olson, had the foresight to take advantage of PaaS, rather than a more straightforward IaaS move.

"If you move to the cloud via lift and shift, and you're taking all of those layers and replicating them,” Mr. Olson told CIO Dive, “You're kind of shoveling them from one location to another, which means you're keeping all that maintenance.”

The College Board also took advantage of the full scope of services offered by their cloud provider of choice to re-architect their applications in a simpler way. This modernization strategy enabled their IT teams to operate faster, more efficiently and at a lower cost compared to their previously-monolithic applications. Mr. Olson calls these the College Board’s “North Stars.”

  This report describes the effects of different industrial factors on  structural quality. Structural quality differed across technologies with COBOL  applications generally having the lowest densities of critical weaknesses,  while JAVA-EE had the highest densities. While structural quality differed  slightly across industry segments, there was almost no effect from whether the  application was in- or outsourced, or whether it was produced on- or off-shore.  Large variations in the densities in critical weaknesses across applications  suggested the major factors in structural quality are more related to  conditions specific to each application.

Open source is part of almost every software capability we use today. At the  very least libraries, frameworks or databases that get used in mission critical  IT systems. In some cases entire systems being build on top of open source  foundations. Since we have been benchmarking IT software for years, we thought  we would set our sights on some of the most commonly used open source software  (OSS) projects.
