Google signed a deal with Shopify Inc. to help host the e-commerce company’s online stores on the Alphabet Inc. unit’s cloud service.

The deal brings a new, fast-growing customer into Google’s fold as cloud chief Diane Greene tries to catch Microsoft Corp. and Inc. in the lucrative business of internet-based computing.

It’s also another case of a retail-related company choosing Google over Amazon’s cloud. Companies including Home Depot Inc. and Williams-Sonoma Inc. have shunned Amazon Web Services in favor of Microsoft and Google because the e-commerce giant is a rival.

Ottawa-based Shopify provides websites and tools to help smaller merchants sell online and compete with retailers like Amazon. The company has grown rapidly since its initial public offering in 2015, with its stock gaining more than 700 per cent.
