- Web Apps
- All deployment slots for the same Web App are hosted within the same Virtual Machine (VM). This is especially important to remember when stress testing a non-production deployment slot prior to swapping it into production. A significant amount of load on a non-production deployment slot can affect the performance of the live, production Web App.
- Any updates made to a blob are atomic. While an update is in progress, requests to the blob URL will always return the previously committed version of the blob until the update is complete.
- Replication Options in Azure Storage: The data in your Microsoft Azure storage account is always replicated to ensure durability and high availability. When you create a storage account, you have four replication options.
Number of copies
Locally redundant storage (LRS) Maintains three copies of your data. Data is replicated three time within a single facility in a single region. Zone-redundant storage (ZRS) Maintains three copies of your data. Data is replicated three times across two to three facilities, either within a single region or across two regions. Geo-redundant storage (GRS) Maintains six copies of your data. Data is replicated three times within the primary region, and is also replicated three times in a secondary region hundreds of miles away from the primary region. Read access geo-redundant storage (RA-GRS) (Default) Maintains six copies of your data. Data is replicated to a secondary geographic location, and also provides read access to your data in the secondary location.
- Route Tables – If you would like to control that traffic that goes out from Azure Virtual Machines, then we would need to use User Defined Routes (UDR)
