Modern networking relies on the public internet, which heavily uses flow-based load balancing to optimize network traffic. However, the most common network tracing tool known to engineers, traceroute, can’t accurately map load-balanced topologies. Paris traceroute was developed to solve the problem of inferring a load-balanced topology, especially over the public internet, and help engineers troubleshoot network activity over complex networks we don’t own or manage.

The VPC means that everything on your digital island is yours, and none of the CSPs other customers can (or should be able to!) access it. You’ve likely been introduced to the shared security model, a sometimes-confusing way that organizations and their cloud-services providers (CSPs) split security responsibilities.
