VPC endpoints and VPC peering connections are two different resources. You can configure either of them based on your connectivity needs.

Security |
All resources in a VPC, such as ECSs and load balancers, can be accessed. |
Allows access to a specific service or application. Only the ECSs and load balancers in the VPC for which VPC endpoint services are created can be accessed. |
CIDR block overlap |
Not supported If two VPCs have overlapping subnets, the VPC peering connection will not work. |
Supported If you use a VPC endpoint to connect two VPCs, you do not have to worry about overlapping subnets. |
Communications mode |
VPCs connected through a peering connection can communicate with each other. |
Requests can only be initiated from a VPC endpoint to a VPC endpoint service, but not the other way around. |
Route configuration |
If a peering connection is established between two VPCs, add routes to the VPCs so that they can communicate with each other. |
For two VPCs that are connected through a VPC endpoint, the route has been configured, and you do not need to configure it again. |
Access using VPN/Direct Connect |
Supported You can create a VPC Peering connection to connect your on-premises data center to a cloud service using a VPN connection or a direct connection. |
Supported You can create a VPC endpoint to connect your on-premises data center to a cloud service using a VPN connection or a direct connection over an internal network. |
