First thank you for your response, I will tell you what I did and you tell me what I need to add.

I used those two files (plz find them attached) with the command heat stack-create my_stack -f autoscaling.yaml.

The stack was spawn correctlty and I can see in the dashboard two instances, the database server and the web server. But I can't access the web server and when I take a look at the members of my pool , it says that my web server is inactive. and After a while it just disappear.

What sort of problems are you having? What is working, and what isn't
working?
