By moving its non-core internal IT support and services work to Infosys, say analysts, Microsoft will be benefitted by focusing on its core product development, marketing and branding exercise. "This will not only help Microsoft in terms of sizable cost savings; it will also help them to move from a capex to opex model. As far as Infosys is concerned, it is a fairly significant deal for them, with a high level of opportunity to expand it to a sizable business," said Sabyasachi Satpathy, MD of Tholons, the IT outsourcing advisory firm.
