When old meets bold

What if legacy systems weren't barriers, but bridges? This story shows how smart wrappers and bold thinking turned outdated tech into connected, sustainable assets—no rip, just wrap. Innovation isn't always shiny. Sometimes, it's just really clever

In the tech world, we talk a lot about disruption. About razing the old to build the new. But what happens when the “old” is too expensive, too embedded, and too critical to throw away?

That’s the question Sanjeev Azad, CTO (APAC) & Global Innovation Head at GlobalLogic, wrestles with on a daily basis.

In this interview, Azad pulls back the curtain on the quiet challenge holding back big sustainability wins: legacy infrastructure. From elevators running on 90s-era protocols to medication dispensers turned smart, this story is all about turning the immovable into the adaptable—with precision, not brute force.

Legacy systems don’t just slow us down, they shut us out

“Legacy systems often become the biggest roadblocks to sustainability initiatives,” Azad begins, cutting straight to the point. Take a typical modernization scenario: you're trying to reduce energy consumption in a commercial building. You introduce an AI-driven HVAC optimizer. Sounds good on paper—until you find out the elevators are still talking in a proprietary language from the early 90s.
