Well, Data/OS Files have to be stored somewhere....EBS evolved to
serve that need...initially Amazon did not support booting off EBS but
now I think they do.

This creates an infrastructure for storing servers as well as EBS data
volumes. Servers can be updated with patches, hardened. Copy images
can be instantiated updated/upgraded and tested...etc.

Why do you say it is not a replacement for a conventional static
server...to me it seems it is better...though one will need to handle
lags/latencies in data access/persistence as storage is network
attached & not direct attached.

Maybe I will gain an insight here...can you please elaborate.

With best regards.
