Azure has features such as geo-replication that protects your data from a major data center incident, but does not provide any performance benefits or availability.
Although quite reliable, sometimes Microsoft reboots the servers for updates, so you can use affinity groups to protect against downtime so that you are always online on your two or more servers. However, this must be used in conjunction with database replication and ideal load balancing.
It is also worth noting that OrientDB recommends that the clusters have an odd number of servers, as this can prevent conflicts when synchronizing data after a communication problem between the servers.
