Azure: Hot and Cold storage explained

"Cold storage tier of Azure Storage is a new tier that is available for Azure Storage for data that needs to be persisted for long time with minimum costs. This tier should be used when data is not accessed frequently."

The newly introduced access tiers of hot and cold storage are well explained in the two links below. In short:

  • Availability: Hot tier 99.99% (RA-GRS) vs Cold tier only 99.9%
  • Cost: "HOT storage cost of storage is higher than the Cold one (more than double), but in the same time the transaction cost is almost double for Cold storage."
  • Latency: for both tiers milliseconds

The truth is that the app.config is automatically read, while any other (correctly formed) app.config XML file can be read "manually".
