Zorluk: OrtaAWS Network Services

A company has exactly two Virtual Private Clouds (VPCs) in the same AWS Region and needs to enable secure, low-latency, and high-bandwidth communication between them. The network traffic must remain within the AWS backbone network, and they want to avoid any additional hourly base charges or per-gigabyte data processing fees. Which AWS networking service or feature should they use to connect these two VPCs?

  1. VPC PeeringCevap
  2. B
    AWS Transit Gateway
  3. C
    Network Access Control Lists (NACLs)
  4. D
    AWS Direct Connect

Cevap

VPC Peering
VPC Peering is the correct option because it allows the routing of traffic between two VPCs using private IP addresses as if they were in the same network. There are no hourly charges or data processing fees associated with VPC Peering itself, only standard data transfer charges, which satisfies the cost constraint.

Adım Adım Çözüm

1
Analyze the requirements for connecting exactly two VPCs in the same region: low-latency, secure, entirely on the AWS backbone, and minimizing costs (no hourly fees or data processing charges).
Identified that the connection is a simple point-to-point VPC-to-VPC connection.
This rules out complex hub-and-spoke systems and external hybrid networking solutions.
2
Compare the cost models of VPC Peering and AWS Transit Gateway.
VPC Peering has no hourly setup charges or data processing fees, whereas Transit Gateway charges both hourly per-attachment fees and per-GB data processing fees.
VPC Peering is the most cost-efficient choice for connecting a pair of VPCs.

Anahtar Kavram

AWS VPC Peering provides a direct, low-latency, and cost-effective connection between two VPCs without extra hourly fees, unlike AWS Transit Gateway which is suited for complex multi-VPC architectures.
