Improving the Office 365 Experience for Millions of Customers

Millions of businesses worldwide use open source technology, and Microsoft is no exception. In fact, one in three Azure Virtual Machines runs Linux, and Microsoft is taking advantage of open source technologies to enhance its own cloud services. For example, the Customer Fabrics Platform Team at Microsoft recently chose DataStax Enterprise—the always-on data platform for cloud applications powered by the best distribution of Apache Cassandra™ — to improve service across multiple areas.

Now, administrators work with DataStax Enterprise to gain insight into user behavior. Results include better support for Microsoft’s fastest-selling product, and more satisfied, productive customers.
