ADB2C - HA/DR 架构查询

Question

I am new to ADB2C and wanted to know in case if we need to consider any architectural things before deciding ADB2C. As per Microsoft documentation, it provide 99.99% SLA but nothing is mentioned about architecture. What if the region(s) goes down? is it something already handled by Azure and we don't need to worry?

Thanks in advance.

Answer 1

AAD is a highly-distributed system , which will continue to work even if a single region goes down. For B2C especially, you have to consider that the SLA only covers specific scenarios:

We guarantee at least 99.99% availability of the Azure Active Directory B2C services. The services are considered "available" in the following scenarios:

• The services are able to process user sign-up and sign-in to the Azure AD B2C services.
• Azure AD B2C successfully emits the authentication and authorization tokens required for users to log into applications connected to the service.
