Maybe a stupid question, but I have searched for a while...
To ensure aws ELB HA, shall I explicitly create two ELB instances in console or aws itself will handle HA for me, so I just need to create one?
Thanks
Yes, it manages HA of itself for you. The main product page mentions this -
https://aws.amazon.com/elasticloadbalancing/
ELB is engineered to be HA. You can see this by performing a dig command on your ELB and seeing that it returns multiple addresses.
By default an ELB will only send traffic to instances in the region the ELB is in. If you want cross region failover you would need to look here - https://aws.amazon.com/blogs/aws/amazon-route-53-elb-integration-dns-failover/
