Azure Blob Storage

Azure Blob Storage (opens new window) enables you to create data lakes for analytics needs and provides storage for building powerful cloud-native and mobile apps.

Workato's Azure Blob Storage connector allows you to automate cloud storage tasks and build data pipelines that automatically pull or push data to Azure Blob Storage from various apps.
