Amazon EC2 High Availability Database Architecture

I am currently developing a solution on EC2. Configure web servers using S3, Cloud Front, Cloud Watch, etc. Simple enough. Using elastic load balancers for HA cross-zone availability for our web servers was also easy.

I would really like to have Cross Region Availability in addition to Cross Zone. This will help reduce the likelihood of a failure due to a disconnected region.

I was not able to find a lot of information about people who use two-way replication cross-region for their dbs. Is it possible? What is the performance?

Before investing a lot of time and effort, you can take into account that Amazon promises to offer high availability on top of the Amazon Relational Database Service (RDS).

New Features for Amazon RDS Coming Soon

High Availability Offer - For developers and businesses who want the added resiliency beyond the automatic backup provided by Amazon RDS at no extra cost. With an offer of high availability, developers and businesses can easily and cost-effectively provide synchronously replicated database instances in multiple availability zones to protect against failures in one place.

Secondly, you need to think about how your general architecture will use these databases: as a warm standby mode or an active member?

Elastic balancing balances will only be balanced within the region, if you want to use cross-region services, you will need other ways to send traffic.
