it possible to have more servers than availability zones. For example, in an
|
|
|
|
|
environment with three availability zones it's now possible to run one voter and
|
|
|
|
|
one non-voter in each availability zone, for a total of six servers. If an
|
|
|
|
|
availability zone is completely lost, only one voter will be lost, so the
|
|
|
|
|
cluster remains available. If a voter is lost in an availability zone, Autopilot
|
|
|
|
|
will promote the non-voter to voter automatically, putting the hot standby
|
|
|
|
|
server into service quickly.
