When multiple MySQL instances provide the same service in your installation, you can apply DNS Service (SRV) records to provide failover, load balancing, and replication services. DNS SRV records remove the need for clients to identify each possible host in the connection string, or for connections to be handled by an additional software component. They can also be updated centrally by administrators when servers are added or removed from the configuration or when their host names are changed. DNS SRV records can be used in combination with connection pooling, in which case connections to hosts that are no longer in the current list of SRV records are removed from the pool when they become idle. For information about DNS SRV support in MySQL, see Connecting to the Server Using DNS SRV Records.
Activation Server 6 uses the best available system regarding availability and data loss - Amazon Aurora. Amazon Aurora is designed to offer greater than 99.99% availability. Recovery from physical storage failures is transparent, and instance failover typically requires less than 30 seconds. Amazon Aurora's storage is fault-tolerant and self-healing. Six copies of your data are replicated across three Availability Zones and continuously backed up to Amazon S3.
