First of all, I am pretty new to AWS, so my question might seem very amateur.
I am a developing a web application which needs to available globally and currently am hosting it on amazon. Since the application is still under development, i have set it up in the Singapore region. However, when i test the application, i get good response times from locations on the the east side of the globe(~50ms). However, when i test the response times from the US, it's ~550ms. So we decided to have 2 instances one in Singapore and one in the US. But i'm not able to figure out a way to handle data replication and load balancing across regions. Elastic Beanstalk only allows me to do this in a particular region. Can somebody please explain how i can achieve global availability for my web app. The following are the services i currently use.
1. Amazon EC2
2. Amazon S3
I need both database replication and S3 file replication. Also it would be great if there was a way where i just need to deploy my application on one place and the changes are reflected across all the instances we would have on the globe.
Before you spend a lot of time and money setting up redundant servers in different regions, you may want to make sure that you can't get the performance improvement you need simply by implementing AWS Cloudfront:
Amazon CloudFront employs a network of edge locations that cache
copies of popular files close to your viewers. Amazon CloudFront
ensures that end-user requests are served by the closest edge
location. As a result, requests travel shorter distances to request
objects, improving performance. For files not cached at the edge
locations, Amazon CloudFront keeps persistent connections with your
origin servers so that those files can be fetched from the origin
servers as quickly as possible. Finally, Amazon CloudFront uses
additional optimizations – e.g. wider TCP initial congestion window –
to provide higher performance while delivering your content to
viewers.

The nice thing is, you can set this up and test it out in very little time and for very little money. Obviously this won't solve all performance problems, especially if you app is performance bound at the database, but this is a good way of taking care of that 'low hanging fruit' when trying to speed up your website in diverse locations around the world.
