title: AWS Services and Regions
body: <p>I am very new with AWS and wanted to clear my concept on AWS services. I have read that that AWS has plenty of services that can also be accessed through API. A service is basically a software program. Then why are services not available in all regions. If my customers are from India, I can buy the EC2 instance from Asia but why should I choose service from USA East. Again, why does AWS provide regions for End Points. They could have installed all the services in all their regions - assuming that they are only software programs and not hardware resources.</p>
