Microsoft Dynamics 365 Finance and Supply Chain Management Business continuity with high availability and disaster recovery

A frequently asked question for new D365 customers is about business continuity and disaster recovery.

First, I like to mention that D365 is a SaaS product and Microsoft is committed to an availability of 99.9% per month of the Service. If Microsoft does not achieve and maintain the service level for the applicable Service described in the SLA, then the Customer may be eligible for a credit towards a portion of their monthly service fees for the applicable Service.

About Business Continuity

The customer’s production instances include High Availability (HA) and Disaster Recovery (DR) features.

• High Availability. HA functionality provides ways to prevent Downtime caused by the failure of a single node within an Azure datacenter. Each Service’s cloud architecture uses Azure availability sets for the compute tier to prevent single-point-of-failure events. HA for databases is supported through Azure SQL (a platform-as-a-service (PaaS) offering from Microsoft).
• Disaster Recovery. DR features protect each Service against outages broadly impacting an entire Azure datacenter and include the following:
  • Azure SQL active-geo replication for primary database (business database), with a Recovery Point Objective (RPO) estimate of ≤ 5 seconds.
  • Geo-redundant copies of Azure blob storage (containing document attachments) in other Azure regions.
  • Same secondary region for the Azure SQL and Azure blob storage replications

For additional information please review the Service Operations Guide (Pages 23, 24, and 26)
