Understanding Premium services, resource usage, and Autoscale
Power BI Premium provides reserved capacity for your organization. This isolates you from the noisy-neighbor problem that you may experience in the shared capacity. Let's start by briefly reviewing the capabilities of the Premium capacities that differentiate it by providing greater performance and scale:
- Ability to Autoscale: This is a new capability that was introduced in Gen2 that allows administrators to assign spare CPU cores to be used in periods of excessive load (not available for PPU).
- Higher Storage and Dataset Size Limits: 100 TB of total storage and a 400 GB dataset size (100 GB in PPU).
- More Frequent Dataset Refresh: 48 times per day via the UI and potentially more via scripting through the XMLA endpoint.
- Greater Refresh Parallelism: You can have more refreshes running at the same time, ranging from 5 (Embedded A1) to 640 (Premium P5/Embedded A8).
- Advanced Dataflows Features: Premium...
