Microsoft CEO Satya Nadella is expected to sign a deal to establish a US$9bn data center facility in the South Korean city of Busan city according to The Korea Herald.

Nadella is set to meet government officials including trade, industry and energy minister Yoon Sang-jick to discuss how both sides can cooperate on investment plans in the country.

Microsoft is expected to invest US$451m over the first five years and continue to invest in the long run. It is expected the facility will cover the entire Asian region once completed.

Microsoft has been investing heavily in infrastructure over the past few years as it refashions itself from a software vendor into a services company.

Its cloud portfolio includes everything from its traditional software offerings provided as a service to Platform- and Infrastructure-as-a-Service offerings under the Windows Azure brand.
