Always online, plus load balancing

We like the Always on feature but we would like to achieve the following scenario, Is it possible if we create a enable a load balancer within Cloudflare?

Scenario:
We have 2 servers.

If server 1 goes down. Can Cloudflare automatically switch the A record/CNAME to Server 2? Do we need to enable Adaptive routing?

Would this work with the Always On feature?
