Application Scenarios

Security-demanding services

You can create a VPC and security groups to host multi-tier web applications in different security zones. You can associate web servers and database servers with different security groups and configure different access control rules for security groups. You can launch web servers in a publicly accessible subnet. But then, to ensure security, you can run database servers in subnets that are not publicly accessible.
