For critical applications, you can distribute endpoint network interfaces across multiple Availability Zones to avoid a single point of failure within a region. This network interface integrates directly with the service's backend infrastructure, so your applications can use standard private IP routing to communicate.
AWS Interface Endpoints Security Benefits: Enhanced Private Connectivity and Reduced Exposure
Traffic destined for these services remains within the Amazon network infrastructure, which reduces exposure to the public internet and often results in more consistent network latency. Key Benefits of Using Interface Endpoints Implementing interface endpoints delivers several operational advantages, including enhanced security through private connectivity and simplified network architecture.
Cost Structure and Pricing Factors You incur costs for interface endpoints based on hourly charges per endpoint and data processing fees. DNS resolution for interface endpoints is handled via Amazon Route 53 internal endpoints, ensuring consistent name resolution within your VPC.
Enhanced Security Through Private Connectivity
Hourly pricing varies by region and reflects the underlying infrastructure that supports the endpoint. Because traffic does not route over the public internet, you can reduce exposure to common threats such as DDoS attacks or internet-based scanning.
