High availability for Dynatrace Managed

AnLee — Wed, 11 Dec 2024 07:26:26 GMT

Hi everyone,
For High Availability (HA) of a Dynatrace cluster, I have read the post Premium High Availability
I understand that Dynatrace automatically replicates data between the nodes in the cluster, but I happened to come across this:

So, for example, if I set up a Dynatrace cluster with 3 nodes, and one node goes down, will any of my data (including transactions) be lost?
Any feedback or advice would be helpful.

Hi AnLee,

3-node cluster is the recommended setup for failover and data redundancy:

And with 3 nodes 3 nodes you get svoid split-brain sync problems.

Hope it helps.
