Subject: Re: EC2 instance recommendations
Yes we can only reboot.
But using rf=2 or higher it's only a node fresh restart.
EBS is a network attached disk. Spinning disk or SSD is almost the same.
It's better take the "risk" and use type i insta

When you restart the OS, you're technically not shutting down the instance. As

We are running on I3s since they came out. NVMe SSDs are really fast and I
managed to push them to 75k IOPs.
As Bhuvan mentioned the i3 storage is ephemeral. If you can work around it
and plan for failure recovery you are good to go.
I ran Cassandra on m4s before and had no problems with EBS
i3 instances will undoubtedly give you more meat for buck - easily 40K+
iops whereas on the other hand EBS maxes out at 20K PIOPS which is highly
expensive (at times they can cost you significantly more than cost of
instance).
But they have ephemeral local storage and data is lost once instance is
