Blob Storage

Table Storage

• Most suitable for binary data (images, video, audio)

• Container-based approach• Streaming and multi-part

• Most suitable for structured data

• Dynamic schema• Partitioning to enable scale

• Most suitable for short messages

• First in, First out mechanism• Limited durability Queue Storage

Then, why so complex?

How do I get that computed hash?

Repeat process for every service call
