Hi Anshu For quick scaling, we’ve had success with an approach of scaling up the compute capacity (attached to EBS) rather than scaling out with more nodes in order to provide relatively quick scale up/down capability. The approach is implemented as part of our managed service but the concept is generic enough to work in any virtualised environment. You can find more detail here if interested: https://www.instaclustr.com/instaclustr-dynamic-resizing-for-apache-cassandra/
