...including the Docker repository and image, memory and CPU requirements, and how the containers are linked to each other. You can launch as many tasks as you want from a single task definition file that you can register with the service.

Very few details but it looks like container lifting across hosts. If so this is great news.

Yes but there are a lot of ways that "the containers are linked together" could be implemented and some of them e.g. key value store require modifying application code quite a bit whereas e.g. DNS does not.

If you want DNS, running e.g. Registrator would be easy enough, and have the added bonus of not tieing your service discovery to AWS.

Wasn't there just an AWS announcement yesterday about the ability to register VPC-private DNS records in Route 53? It screamed "SkyDNS competitor" to me but I couldn't figure out what Amazon wanted such a thing for. Makes sense now.

Route 53 launched private (vpc) dns last week. Its actually a common pattern to manage ec2 instances via dns records. Many people had built this on top of the public route53 offering, see zonify from airbnb as an example. Private dns improves on that model as the vpc instances never have to communicate with the public internet now.
