On-premises storage vs Azure data storage

Why migrate to cloud


Needs On-premises Azure data storage
Compliance and security Dedicated servers required for privacy and security Client-side encryption and encryption at rest
Store structured and unstructured data Additional IT resources with dedicated servers required Azure Data Lake and portal analyzes and manages all types of data
Replication and high availability More resources, licensing, and servers required Built-in replication and redundancy features available
Application sharing and access to shared resources File sharing requires additional administration resources File sharing options available without additional license
Relational data storage Needs a database server with database admin role Offers database-as-a-service options
Distributed storage and data access Expensive storage, networking, and compute resources needed Azure Cosmos DB provides distributed access
Messaging and load balancing Hardware redundancy impacts budget and resources Azure Queue provides effective load balancing
Tiered storage Management of tiered storage needs technology and labor skill set Azure offers automated tiered storage of data
