Developers can use SQL Server Data Tools (SSDT) in Visual Studio for creating models and deploying them to the service. Administrators can manage the models using SQL Server Management Studio (SSMS) and investigate issues using SQL Server Profiler
Business users can consume the models in any major BI tool. Supported Microsoft tools include Power BI, Excel, and SQL Server Reporting Services. Other MDX compliant BI tools can also be used, after downloading and installing the latest drivers
The service currently supports tabular models (compatibility level 1200 only). Support for multidimensional models will be considered for a future release, based on customer demand
Between tabular-only support and the max size being 100 GB (if I’m reading this correctly), they’re not yet ready to push the product hard. Given that it just came out, that makes sense, and hopefully the training wheels come off.
