AWS Route Table

This blueprint creates an AWS Route Table associated with a specified VPC. It allows users to define multiple routes using section tags, adhering to best practices by encouraging the use of tagging for resource identification and management. The blueprint is organized into groups to assist users, including those who may not be cloud infrastructure experts, in configuring essential settings and routes easily.
