According to the Statista Technology Market Outlook 2020, U.S. revenues earned with public cloud computing services are expected to surpass $45 billion this year. That's roughly eight times the size of the next smaller market in China. By 2025, revenues are projected to rise to $93 billion in the U.S. and $28 billion in China.
Infrastructure-as-a-service accounts for more than half of sales. The segment consists of cloud-based IT services for storage and computing (e.g. large data). The largest providers here are Amazon Web Services, Microsoft Azure and Google. The remaining revenue is attributable to the platform-as-a-service area. This includes cloud-based IT services for operating systems, developer tools, database management and business analytics. Amazon Web Services, as well as Microsoft Azure, are the largest providers in this segment.
Other countries with a modestly strong cloud market are the UK and Japan, even though growth is expected to stay behind that of China. By 2025, the countries’ markets are expected to grow to a volume of $5.8 billion and $7.8 billion, respectively.
