Microsoft Azure is the public cloud platform of Microsoft. It sells virtual machines, storage and networking billed by usage, and a wide catalogue of platform services, to enterprises and developers.
Its geographies page lists live regions in the United States, Canada, Brazil, Australia, China, Japan, South Korea, India, Indonesia, New Zealand, Austria, Belgium, Denmark, France, Germany, Italy, Norway, Poland, Spain, Sweden, Switzerland, the United Kingdom, Israel, Qatar, the United Arab Emirates and Saudi Arabia. Several regions are separate sovereign or national clouds, such as the one in China, and these can have different terms, so a buyer needing a particular country should confirm availability and contracting arrangements with the provider.
The same page marks Chile, Mexico, Finland, Greece, Taiwan and Malaysia as coming soon, so they are not counted here.
