Comparison of Azure Container Registry Service Tiers

Paraphrased summary of Azure Container Registry (ACR) features from the official documentation -

Azure Container Registry is a managed Docker registry service based on the open-source Docker Registry 2.0.

Azure Container Registry (ACR) is available in multiple service tiers with several options for aligning to the capacity and usage patterns of your private Docker registry in Azure.

Azure Container Registry SKUs	Basic	Standard	Premium
Price per day	A cost-optimized entry point for developers learning about Azure Container Registry. Basic registries have the same programmatic capabilities as Standard and Premium (such as Azure Active Directory authentication integration, image deletion, and webhooks). However, the included storage and image throughput are most appropriate for lower usage scenarios.	Standard registries offer the same capabilities as Basic, with increased included storage and image throughput. Standard registries should satisfy the needs of most production scenarios.	Premium registries provide the highest amount of included storage and concurrent operations, enabling high-volume scenarios. In addition to higher image throughput, Premium adds features including geo-replication for managing a single registry across multiple regions, content trust for image tag signing, and firewalls and virtual networks (preview) to restrict access to the registry.
Included storage (GiB)	10	100	500 Premium offers enhanced throughput for docker pulls across multiple, concurrent nodes
Total web hooks	2	10	100 (additional available upon request)
Geo Replication	Not Supported	Not Supported	Supported
