AWS RDS Details

• Overview
  
• AWS creates db instance in a subnet (AZ) of any network (vpc)
• AWS expects us to provide more than one subnet while creating databases, this is referred as db subnet group
• AWS VPC by default allows all traffic internally i.e. all private communication is allowed
• If your application and rds is in same vpc all you need to know is names(ip addresses)
• If your application and rds are in different networks we need some extra configuration at networking level
  • VPC peering
  • VPN
