AWS Network Firewall Supports Transit Gateway Attachment for Cost Optimization
Key points
- AWS Network Firewall supports direct attachment to Transit Gateway.
- Eliminates the need for a dedicated inspection VPC.
- Enables flexible cost allocation using Transit Gateway metering policies.
Introduction to Transit Gateway-attached Network Firewall
AWS Network Firewall can now be natively attached to AWS Transit Gateway. This feature empowers users to streamline traffic routing from various Amazon VPCs to a centralized firewall setup for better security and performance.
Benefits of the New Feature
The primary advantage of this new attachment capability is the elimination of the traditional dedicated inspection VPC model. Users can now route traffic through firewall endpoints managed by AWS, significantly optimizing costs and simplifying the network architecture.
Technical Implications
Users deploying this setup no longer need to manage firewall subnets or the associated routing configurations. Instead, they can create a network firewall and link it directly to the preferred Transit Gateway instance.
Migration Assistance and Documentation
AWS provides resources to assist customers in migrating to this new model. Detailed guides are available for performing the migration using Terraform, AWS CloudFormation, or manually through the AWS Management Console. These resources aim to facilitate a smooth transition for users wishing to adopt the Transit Gateway-attached network firewall setup.
