Hi Nitan, You shouldn’t have any issues if you setup things properly.
Few possible issues could be (can become a bottleneck) * CPU allocation (Instances can compete) * Disk throughput & IOPS & * Port allocations * Network throughout * Consistency issues. And we have work around for all above, * CPU: Use jvm file to limit number of CPU cores for each instance. * DISK: If possible allocate dedicated disks for each instance. * NETWORK & Ports: Have a secondary NIC (or equivalent to num of instances). This will give you the flexibility to have Cassandra on same ports with better networking operations. * RACK: having multiple instances on one node can lead to consistency problems when a hosted node goes down for some reason with having RACK’s defined. So, this is very important to choose when going with this kind of setup. Hope this helps!
