Read replica is a copy of the primary database instance in RDS that allows read-only access to the data.
Read replicas can be used to offload read traffic from the primary database instance.
They can be created in the same region or in a different region for disaster recovery purposes.
Read replicas are asynchronous, meaning that changes made to the primary instance may not be immediately reflected in the read replica.

VPC Endpoint in Amazon S3 allows direct access to S3 from within a VPC without going over the internet.
VPC Endpoint provides a secure and private connection between VPC and S3.
It eliminates the need for a NAT gateway or VPN connection.
It improves security by keeping traffic within the AWS network.
It reduces data transfer costs and improves performance.
Examples: accessing S3 buckets from EC2 instances in a VPC, using S3
VPC Peering is a networking connection between two VPCs that allows them to communicate using private IP addresses.
VPC Peering enables inter-VPC communication within the same AWS region.
It is a secure and low-latency connection.
Peered VPCs can share resources like EC2 instances, RDS databases, etc.
Transitive peering is not supported, meaning VPCs cannot be peered through a peered VPC.
Peering connections can be establis
