Mongo Atlas, how to add additional replica set nodes

MongoDB Atlas
1

Hi,

Probably missing it, but …
being searching on how to add additional replica set nodes, to a standard 3 nodes Atlas cluster, but have reviewed the Atlas interface, and the cluster configuration/change options, but can’t find where/how to add extra replica set nodes, so that we have higher read capacity.
Thanks for indication on where /how this is done.

Hi @Werner_Michels,

The Cluster has to be M10+

It is documented here:

Hi @chris ,
Sorry forgot to mention it’s a M50 cluster on AWS cloud.
thanks for the hint on documentation where to find it.

Hey @chris

I have a question regarding this node. Is it possible to add an EC2 instance as a node in MongoDB Atlas using the method you suggested?

Hi @Mehul_Sanghvi

You cannot ‘bring your own’ EC2 and add it to the cluster. MonogDB Atlas does allow expansion of the cluster from the default 3 member replica set and you can also spread the cluster among multiple cloud providers.

What is your use case for this ?
