In this section I will explain the different ways to replicate traffic in AWS along with the pros & cons of each approach. Using AWS VPC Mirroring is the best approach for replicating traffic for applications deployed on AWS. The benefits of replication goes beyond just monitoring and troubleshooting issues. The information can be used in performing data analysis, analyze traffic pattern and in detecting security vulnerabilities and attacks on the system. The best approach is to use GoReplay, which can be installed on an EC2 instance.
