Dell plans to buy Make Technologies, which specialises in helping businesses replace outdated IT systems, its third enterprise-related acquisition announcement this week.

Make Technologies aims to reduce costs for companies that use business-critical legacy systems, which are old applications or computer systems that continue to be used, even if there are newer products that do a better job and are often cheaper to run. Make Technologies migrates those legacy systems to a cloud infrastructure or other open standardised platforms.

Dell is going to acquire the company to add a faster, more reliable and cost-effective approach to the re-engineering of applications, the company said. Make Technologies provides automated application and code migration tools that help migrate legacy applications to a more modern architecture.

Terms of the deal to buy Make Technologies, which is based in Vancouver, were not disclosed. The approximately 100 Make Technologies employees will be added to the Dell Service team, and the deal is expected to close in the second quarter of the company's fiscal year.

On 2 April, Dell announced it has agreed to buy Wyse Technology, a maker of software and hardware for thin clients. And a day later Dell announced it had purchased application modernisation vendor Clerity Solutions.

Dell said that it plans to combine Make Technologies and Clerity into its existing Dell Services, which include application services, IT consulting and business process services.
