 ## Availability zones
 
-Cassandra's peer-to-peer architecture brings fault tolerance from the ground up. Azure Managed Instance for Apache Cassandra provides support for [availability zones](/azure/reliability/availability-zones-region-support) in selected regions. This support enhances resiliency at the infrastructure level. For a replication factor of 3, availability zone support ensures that each replica is in a different availability zone. This approach prevents a zonal outage from affecting your database or application. We recommend enabling availability zones where possible.

 **Q. How does the Azure Database for MySQL - Flexible Server 99.99% availability SLA differ from MariaDB?**
 
-A. Azure Database for MySQL - Flexible server zone-redundant deployment provides 99.99% availability with zonal-level resiliency, whereas MariaDB provides resiliency in a single availability zone. Flexible Server's High Availability (HA) architecture deploys a warm standby with redundant compute and storage (with each site's data stored in 3x copies) as compared to MariaDB's HA architecture, which doesn't have a passive hot standby to help recover from zonal failures. The flexible server's HA architecture enables reduced downtime during unplanned outages and planned maintenance.

 ### Default zone-resiliency for Business-Critical service tier
 
-You now benefit from the highest level of availability against infrastructure failures within an availability zone at no extra cost for mission-critical workloads running on the Business-Critical service tier. Regardless of whether your flexible servers are enabled with High Availability (HA), your server data and log files are hosted in zone-redundant storage by default. While zone-redundant HA-enabled servers continue to benefit from a 99.99% uptime SLA from the built-in zonal redundancy and hot standby, non-HA servers can recover quickly from zonal outages using zone-redundant backups. This enhancement applies to all new servers provisioned in the Business-Critical service tier.

 > [!NOTE]  
 > Based on customer feedback requesting the ability to choose their preferred deployment type, we've decided to roll back Default zone-resiliency for Business-Critical service tier. Now, for both Memory Optimized and General-Purpose servers, customers must select the High Availability (HA) mode either same-zone or zone-redundant at the time of server creation. This selection is final and can't be modified later.
