Question
A company wants to connect its supported AWS services and VPCs. The company does not want to expose its internal traffic to the public internet.
Which AWS service will meet these requirements?
A. Amazon Inspector
B. AWS PrivateLink
C. Amazon Connect
D. AWS Internet Gateway
Answer
B. AWS PrivateLink
Explanation
AWS PrivateLink is the correct answer because it allows you to securely connect your VPCs to supported AWS services, your own services, and third-party SaaS applications without exposing your traffic to the public internet.
With AWS PrivateLink, you can establish private connectivity between VPCs and services running in other VPCs, AWS accounts, or on-premises environments. It uses private IP connectivity and network isolation to keep traffic within the AWS network.
PrivateLink works by creating interface VPC endpoints for supported services in your VPC. These endpoints provide private connectivity to the service and appear as elastic network interfaces with private IPs in your VPC subnets. This allows instances in your VPC to communicate with the service using their private IP addresses, without needing public IP addresses or internet gateways.
Benefits of AWS PrivateLink include:
- Increased security by keeping traffic private and off the public internet
- Reduced exposure to threats like DDoS attacks and malware
- Simplified network architecture without complex firewall rules
- Consistent performance and low latency through optimized AWS networking
The other options are incorrect:
- Amazon Inspector is a security assessment service, not a networking service
- Amazon Connect is a cloud contact center service
- An Internet Gateway allows communication between instances in your VPC and the internet, which is the opposite of what the question requires
Therefore, AWS PrivateLink is the best choice for securely connecting VPCs and services without using the public internet.
