Finland's Nokia NOKIA.HE has signed a 5-year deal with Google GOOGL.O to replace its IT infrastructure, including data centers, with Google's Cloud offering as the network equipment maker seeks to cut costs, it said on Wednesday.

“The agreement is expected to drive meaningful operational efficiencies and cost savings over time due to a reduction in real estate footprint, hardware energy consumption, and hardware capacity purchasing needs,” it said in a statement.

It did not unveil the financial details of the contract, but said it will take 18-24 months for the full migration.
