* Azure Service Health helps you assess the health of Azure, while Azure Monitor helps you determine if there are any issues on your end. Both services use the same alerting platform to keep you notified and informed of the availability and performance of your Azure workloads. This means that you can set up an action group once and use it multiple times for different scenarios. Azure Monitor and Azure Service Health are complementary services that you will often use together when troubleshooting issues. The Azure Status page only reports on major, widespread outages and doesn’t include any information about planned maintenance or other health advisories.

Azure Shared Image Gallery allows sharing of an organization's  images among different users, service principals, or AD groups. An image is a copy of either a full VM (including any attached data disks) or just the OS disk, depending on how it is created. When you create a VM from the image, a copy of the VHDs in the image are used to create the disks for the new VM. The image remains in storage and can be used over and over again to create new VMs.
