 1.	A XRP node deployed in the [Default VPC](https://docs.aws.amazon.com/vpc/latest/userguide/default-vpc.html) continuously synchronizes with the rest of nodes on the configured xrp network through [Internet Gateway](https://docs.aws.amazon.com/vpc/latest/userguide/VPC_Internet_Gateway.html).
 2.	The XRP node is used by dApps or development tools internally from within the Default VPC. RPC API is not exposed to the Internet directly to protect nodes from unauthorized access.
 3.  The XRP node sends various monitoring metrics for both EC2 and current XRP ledger sequence to Amazon CloudWatch. It also updates the dashboard with correct storage device names to display respective metrics properly.

 1.	A set of XRP nodes are deployed within an [Auto Scaling Group](https://docs.aws.amazon.com/autoscaling/ec2/userguide/auto-scaling-groups.html) in the [Default VPC](https://docs.aws.amazon.com/vpc/latest/userguide/default-vpc.html) continuously synchronizing with the rest of nodes on the configured xrp network through [Internet Gateway](https://docs.aws.amazon.com/vpc/latest/userguide/VPC_Internet_Gateway.html).
 2.	The XRP nodes are accessed by dApps or development tools internally through [Application Load Balancer](https://docs.aws.amazon.com/elasticloadbalancing/latest/application/introduction.html). RPC API is not exposed to the Internet to protect nodes from unauthorized access.
