The chief information officer at John Holland has told ZDNet that the construction, infrastructure and services company will complete the migration of its systems onto Amazon’s cloud-based Amazon Web Services (AWS) platform by June.

Chris Walsh revealed to the IT news site that the firm is 75% through the process of uploading its legacy systems to AWS.

“All legacy, entire datacentres, the works. We’ve got some really old estimating apps that are traditional DOS-based systems that are pretty gnarly when it comes to migrating hosting to AWS … we think we’re going to be OK,” he said.

“Putting things in AWS allows us to put things closer to where the projects are and also the regional offices,” he explained. “That was one of the drivers — cost was not — it was agility, placing services closer to my customers and users, and cost may come fourth or fifth.”
