Subject Re: Cassandra on Cloud platforms experience
Date Fri, 04 Nov 2016 09:10:06 GMT
So I've run Cassandra on both Aws and azure. I would strongly suggest that if you have the
option, run as far away from azure as you can. 

Here's a list of issues I have running Cassandra on azure:
1. No native snitch 
2. No concept of availability zones. This makes it impossible for Cassandra to put replicas
in different AZs. This will hurt your uptime and might incur loss of data. (They have something
called a fault domain tho)
3. The disks have iops that land in the floppy disk range 
4. Even running SSDs will give you poor performance.
5. Beware of the global storage account limit. This makes scaling out hurt performance if
you put them on the same storage account. Which if your using images is your only choice.
