Terms in this definition
- Azure Database for MySQL
Managed Azure hosting for MySQL Community Edition relational databases, now in its flexible server form. Azure handles backups and patching, offers zone-redundant high availability, and it is often chosen for LAMP stack applications.
- Zone-redundant
Distributed over every availability zone in a region, allowing it to withstand losing one zone; a StandardV2 NAT gateway is an example.
- HA
High availability means a service keeps running despite local failures, for instance by spreading replicas across zones.
- General Purpose
An Azure SQL service tier that pairs a single compute node with remote storage. Compared with Business Critical it has higher latency and lacks a synchronous replica.
- Business Critical
Azure SQL vCore tier offering the lowest latency by running Always On replicas on local SSD, plus zone-redundant failover that loses no data; serverless isn't offered.
