Haproxy high availability setup in AWS


We are using haproxy as a single node using docker for a while and it has been working very well.
Now we plan to setup high available HA-Proxy to avoid SPOF.

I went through this blog: HAProxy on AWS: Best Practices Part 3 - HAProxy Technologies. Here they use Enterprise version of HaProxy which confuses me, Can I not use the same setup for community version of haproxy ?
