amazon web services - What's AMI ImageType? -
there image-type in describe-images filter, , imagetype in response, no info stands for, , cannot find info googling.
there 3 types: machine, kernel, ramdisk, mean?
if using ami images provided else, can ignore them -- you'll need utilize ami identifier when booting new instances.
a bit more detailed answer: ramdisk image (ari) , kernel image (aki) used part of boot sequence of linux instance.
more accurately:
hardware virtualized (hvm) instances not utilize ari or akis @ all. of boot sequence part of ami itself. includes both ebs , instance-store backed instance types. paravirtualized (pv e.g. running on xen) ebs-backed instances need aki, , paravirtualized instance-backed instances need both aki , ari.while amis unique, aki/aris can reused. example, aki-88aa75e1
kernel image used (in us-east-1
, public images) 5413 amis , ramdisk ari-a51cf9cc
683 amis. both of these images provided amazon , trusted others when they're building amis. if bundle instance-store/paravirtualized machine ami it'll inherit ari , aki original ami many people publishing amis implicitly re-use those.
also note windows requires hvm, ari/aki not applicable windows instances @ all.
