The smoking gun is probably the box that was previously labelled "Media Conversion Service" (Elemental MediaConvert - easily 5-6 figures/mo. for a small amount of snappy on-demand capacity, or crippled slow-as-molasses reserved queues) now labelled "Media Converter" running on ECS. For example, vt1 instances are <$200/mo. spot and each instance packs enough transcode to power a small galaxy, for fine-grained tuning an equivalent CPU-only transcode solution isn't that much more expensive either. At some point the industry will wake up to the fact the AWS pricing pages are the real API docs, meanwhile dumb shit like this will keep happening over and over again, and AWS absolutely are not to blame for it, any more than e.g. a vendor of cabling is guilty of burning down the house of someone who plugged 10 electric heaters into a chain of double-gang power extension cords
