- System will not go down even if one of our datacenters is damaged.
How to Execute
- Create new virtual machines which have identical configurations in each zone (jp-e1a and jp-e1b)
- Create LBA(Load Balancer) to work in multi zones. Register each virtual machine with the LBA to distribute traffic to those machines.
- Configure DNS service (creating hostzone), and create a CNAME record for LBA which was created in step 2.
Registering a CNAME record for LBA that works in multiple zones enables the system to distribute inbound traffic to multiple zones using DNS Round Robin.
