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.


DataStax Enterprise on Azure enables us to do everything we needed, including near-real-time data processing and longer-term batch processes. We’re also able to handle linear data growth without having to shard our clusters and manually manage data.

The Opportunity

Provide the best possible user experience for Office 365 productivity platform customers.

Detect user problems proactively, before they notice it themselves.

Tap into more than 300 terabytes of anonymized data from client and server logs to gain user behavior insights.

The Solution

The Results

Reduced support tickets. By targeting both server-side and client-side log data, the team could determine if a problem originated internally or from tenant administrators and solve problems before they escalated.

Faster fixes. Administrators can see if users make multiple attempts to file a support ticket, indicating that either the page isn’t working or needs to be redesigned.

Proactive customer support. They can identify which users are affected by a service incident and proactively contact them.
