- Zonal services: pin resource to specific zone
- Zone-redundant services: automatically replicated across zones
- Azure Region Pairs: azure regions are paired with another region within the same geography at least 300 miles away
Resources
- Resource: A manageable item that’s available through Azure. Virtual machines (VMs), storage accounts, web apps, databases, and virtual networks are examples of resources.
- Resource group: A container that holds related resources for an Azure solution. The resource group includes resources that you want to manage as a group. You decide which resources belong in a resource group based on what makes the most sense for your organization.
- Azure Resource Manager: Deployment and management services, receives the request and authenticates/authorizes based off of it. Used with a JSON template, applies RBAC, tags, and allows organization for cost.
Subscriptions
You can create billing and access control boundaries to determine how a product is billed and to manage and control access to resources.
Additional subscriptions can be created to accommodate environments, organization structures, billing, and subscription limits.
Management groups hold on top of subscriptions, and 10,000 of which can be supported in a single directory up to six levels of depth. Each management group and subscription can support only one parent, while each management group can have many children.
