A discrete market typically containing two or more regions that preserve data residency and compliance boundaries. What is an Availability Zone? physically separate datacenters within an Azure region, made up of one or more datacenters equipped with independent power, cooling, and networking. It is set up to be an isolation boundary. What is a Region Pair? Two regions within the same geography (such as US, Europe, or Asia) at least 300 miles away, used to avoid availability zone outage What is an SLA? Formal documents that capture the specific terms that define the performance standards that apply to Azure. What are the three key characteristics of SLAs for Azure products and services? Performance Targets, Uptime and Connectivity Guarantees, and Service credits What is Azure AD? A cloud-based, modern identity provider that supports multiple authentication protocols to secure applications and services in the cloud. It can be used standalone or synchronized with on-premise AD. What is a blade? a slide-out panel in the Azure Portal containing the UI for a single level in a navigation sequence What is a dashboard? a customizable collection of UI tiles displayed in the Azure portal.
