According to a Microsoft blog post, Solair's technology will be used to upgrade the company's Azure IoT Suite, a collection of cloud services meant to help companies use the Internet of Things.
Microsoft and Solair didn't disclose the financial terms of their deal.
Solair's technology, which already uses Microsoft's Azure cloud services, offers IoT services focused on a variety of markets, including home automation, smart metering, remote maintenance and inventory management.
Microsoft didn't say specifically what it will get out of Solair's technology, but it promised to release more details on the integration of the two companies later.
Microsoft acquired Solair for its technology, not its customer base, MachNation analyst Dima Tokar wrote in a commentary. Sam George, the partner director for Azure IoT, said in a blog post that Microsoft is excited about the technology and talent that will come with the acquisition.
Azure is a key part of Microsoft's corporate strategy. The company is betting big on getting more customers to use its cloud offerings, and acquisitions like this one are aimed at getting more companies to buy into the Azure ecosystem, especially for new workloads like those driven by IoT.
