You are designing an Azure application that stores data.
You have the following requirements:
– The data storage system must support storing more than 2 terabytes (TB) of data.
– Data retrieval must be possible from a large number of parallel threads.
– Threads must not block each other.
You need to recommend an approach for storing data.
What should you recommend?
A. Azure Notification Hubs
B. A single SQL database in Azure
C. Azure Queue storage
D. Azure Table storage
Correct Answer: D
Explanation/Reference:
* Azure Table Storage can be useful for applications that must store large amounts of nonrelational data, and need additional structure for that data.
Tables offer key-based access to unschematized data at a low cost for applications with simplified data-access patterns. While Azure Table Storage stores structured data without schemas, it does not provide any way to represent relationships between the data.
* As a solution architect/developer, consider using Azure Table Storage when:
/ Your application stores and retrieves large data sets and does not have complex relationships that require server-side joins, secondary indexes, or complex server-side logic.
/ You need to achieve a high level of scaling without having to manually shard your dataset.
