AWS storage performance

A common question is "How would the client compare the performance of storage on Amazon vs. local data center? "  Well here are some numbers for AWS storage:

a.   Instance storage Disk : Equivalent to local disk for a server

b.   Instance storage SSD

                                                             i.     ~120,000 random read IOPS (4 KB blocks)

                                                            ii.     ~10,000-85,000 random write IOPS (4 KB blocks)

c.    EBS Standard (100 IOPS)

                                                             i.     Reads typically <20ms writes typically <10ms

                                                            ii.     Best effort to 10’s of MB/sec

d.   EBS PIOPS (4K IOPS),

                                                             i.     On best effort, you may get up to 40 MB/sec throughput for 2K PIOPS disk

e.   S3 : loading :http://cloudconclave.blogspot.com/2013/05/aws-s3-load-throughput.html

f.     Glacier : Long time archiving. Takes 3-5 hours to retrieve.

g.   Storage Gateway : On premise to AWS S3 ‘replication’.  So, will depend on the pipe (internet, AWS DirectConnect) from on premise to AWS.
