title: AWS WordPress High Availability EFS, EC2 and MySQL database
body: <p>I'm building a Wordpress high availability service.  I know a little about Wordpress, but not sure how to get it working and setup for HA.   I've done reading from various articles, but not sure how tolerant Wordpress is when changes occur on one host and now the other host will react.</p>
  
  <p>I'm starting with 2 EC2 instances, EFS(NFS) and RDS MySQL database.   The EFS is used to share the application configuration/data/content on both instances.  RDS MySQL database will be shared on both instances as well.   Does anyone see any hurdles with this design?   I'm wondering how Wordpress plugins gets updated on one host and if the other host will see the same updates dynamically.</p>
