Magento 2 in AWS with auto-scaling and CDN

[Karthikjaps]

I am looking for some suggestions from you 

This is our current Architecture, we using Magento2 with Nginx (Using Magento Front-End itself) in single -server

 

I am looking for suggestions for auto-scaling and CDN

 

For auto-scaling

• I have already tried to set up auto-scaling with 2 servers in load -balancer due to Magento-front-end we facing session and caching issues, also due to dynamic user date sync-up in /pub/static we are unable to make it stable
• I have tried to use EFS with a single mount for two-server but it makes low performance due to EFS behavior
   

  For CDN I have tried AWS CloudFront with the below Architecture

   

  For Example

  current load-balancer site - DNS mapped with the web. example. com

  I have to create two distributions (media.example.com  and static.example.com) with origin as load-balancer and also Site-name web. example. com

   

  After I update Magento static and Media URLs like  

  Spoiler

  media.example.com/pub/media and static.example.com/pub/media, CND not working fine with an Error of 404 and a broken site, I have up...

   

  Please suggest recommended the method Magento CDN and Auto-scaling to make in production mode with Good performance

   

  There is possible to use static or Media in S3 or be able to separate both from one server?
