you can also pickup an enterprise flash device and have a few terabytes of 500k+IOPs for a few grand whereas reaching a similar performance profile via provisioned IOPs will cost you 10x as much every month.
- Johnny555 9y agoYou're comparing apples to oranges -- if you want a couple TB of locally attached storage, you'd get an i3.2xlarge for $450/month with 1.9TB of NVMe SSD (plus 8 cores CPU + 60GB RAM). Using EBS volumes with provisioned IOPS give you some advantages that you don't get with a bare SSD -- like snapshot support and the ability to easily detach it and move it to another server.
- gfody 9y agoyou're right, the performance of the local storage on i3 instances is a lot better than normal EBS but still nothing close to what you would get from just buying an Intel P4500 or similar though. http://www.aerospike.com/benchmarks/amazon-ec2-i3-performance-results/ http://www.aerospike.com/benchmarks/amazon-ec2-i3-performanc...
