Formation of CDP’s NFS Sharing Pattern.

Using single Amimoto instance as an NFS sharing server, AutoScale Amimoto instances (behind ELB) share it. Use  Multi-AZ Amazon RDS instances as MySQL databases.

AutoScale instances behind ELB will be increased or decreased automatically depending on the server load, so it will handle the spiked requests with minimum time.

Also, using Multi-AZ instances for the database, it will improve fault tolerance and reliability with  automatically backed up and  fail-over.
