FIS Global (FIS) has expanded its relationship with Webster Bank in Waterbury, Conn.

The banking technology company in Jacksonville, Fla., said Wednesday that it forged a multi-year deal with Webster, a subsidiary of Webster Financial (WBS), to manage significant parts of the $20 billion-asset bank's IT platform and operations.

As part of the agreement, FIS will manage Webster's desktop computing and databases, as well as the bank's computing network and servers.

"Webster and FIS have a longstanding relationship, and our technologies and services closely align with Webster Bank's goals of offering best-in-class services at optimal cost and risk," Anthony Jabbour, FIS' executive vice president for North American financial institutions, said in a press release.

According to FIS, the move to outsource management of IT services will help Webster control spending while building a technology infrastructure that can address clients' needs.

"As we grow, Webster needs reliable technology partners to provide robust infrastructure and services so we can focus on delivering on our customer promise, and FIS is the partner we can always rely on," Jerry Plush, Webster's chief operating officer, added in a press release.
