All-at-once contradicts the official AWS documentation

According to this link (, the ‘All-at-once’ statement about terminating old instances and spin up new instances, is wrong.>

Not to mention rolling is also wrong. Come on ACG, do better than this. Your SAA got it right, why is this wrong?

Hi Paquito and Adam,

It took me a while to figure out what you were referring to but now I know…  For those who find this later, All At Once and Rolling deploys for Elastic Beanstalk use existing instances instead of new instances.  We’ll update with that distinction.

The AWS documentation didn’t use to explain it in that detail and it seems that level of detail in the documentation was added since the video in the course was recorded.
