Webapplication deployment model for cloud

I have a webapplication where the front-end(in js,html,css) is seperate from the back-end(springboot, mysql). I want to deploy this on cloud like GCS. What is the best model for me. Can I use a Google Storage (or s3) bucket for my front-end and connect it to my back-end which I can put in a couple of Compute VMs(or ec2) and load balance it. I'm also looking to manage authentication using login/password. Is there a better model for my case or does this suffice for higher loads as well.
