You realize that netflix is using up over 20% of aws capacity and as cool as having your own cdn is there is not much purpose in it without the part that runs on AWS.

The part that runs in AWS could just as easily run on bare metal. Stack Overflow does it, Backblaze does it, Github does it; I'm so disappointed in this tired trite that your a special snowflake running in AWS.

Yes it would run even better but it would take a few years to do the buildout.

Nothing is going disappear overnight.. AWS iaas services are commodity and not something so unique that are not replaceable with products from other cloud vendors

At Netflix scale they are not replaceable by other vendors because other vendors do not have enough capacity to accommodate Netflix migration.

Can you provide information as to how much capacity Netflix would need to migrate? Otherwise, this comment has no basis in reality.

there are estimates that netflix is consuming about 20% of AWS. AWS does not publish a list of DCs but from regions and AZs you can put a lower bound estimate at 40 so it would be anywhere from 8 DCs to whatever the upper bound is (I guesstimated 20)
