Azure Storage tables and Azure Cosmos DB tables

Azure Table storage is a service that stores non-relational structured data (also known as structured NoSQL data) in the cloud, providing a key/attribute store with a schemeless design.
Azure Cosmos DB provides the Table API for applications that are written for Azure Table storage and that need premium capabilities like high availability, scalability, and dedicated throughput.

Differences in behavior

You are charged for the capacity of an Azure Cosmos DB table as soon as it is created, even if that capacity isn’t used.
Query results from Azure Cosmos DB are not sorted in order of partition key and row key as they are from Storage tables.
Row keys in Azure Cosmos DB are limited to 255 bytes.
Cross-Origin Resource Sharing (CORS) is supported by Azure Cosmos DB.
Table names are case-sensitive in Azure Cosmos DB. They are not case-sensitive in Storage tables.
