The shop runs as the Auto Scaling group web-asg: two instances from the launch template web-lt, behind market-alb and its target group web-tg. Version 1 of the shop is live. Version 2 is in ~/v2.sh.

1. Keep web-tg's ARN in TG and the load balancer's DNS name in DNS.
2. Give the group a target-tracking policy named cpu50 that keeps its average CPU at 50%.
3. It is Monster Monday. Send five minutes of load through the load balancer, from 10 workers at 10 requests a second each. Then check what the group did, and why.
4. Make ~/v2.sh version 2 of web-lt, starting from version 1.
5. Roll version 2 out to every instance of the group. The rule for releases: the shop never runs on fewer healthy servers than it has when the release starts.
6. Check the release until it is Successful, and fetch the shop to see version 2.
