The five-year contract for end-to-end IT infrastructure services will transform the airline's IT operations to deliver seamless internal customer experience, TCS said in a statement.
However, the size of the deal was not disclosed.
"One of the key initiatives include fine tuning our IT outsourcing strategy to deliver the required business results at lower cost. At the same time, we will continue to work with our key vendors to maximise service delivery and to proactively address other business requirements," MA Chief Information Officer Faridah Abdul Rahman said.
TCS will undertake IT infrastructure management of the airline's data centres, IT networks and IT security.
It will also set up a service management organisation under a 'Build, Operate and Transfer' methodology for MA.
"We are delighted to partner with MA and will leverage our expertise and best practices to help them achieve their strategic business transformation objectives, enabling them to capture the growth in the global aviation market," TCS Head (Asia Pacific) Vish Iyer said.
