Amazon VPC Flow Logs: Amazon VPC Flow Logs can be used to capture information about the IP traffic going to and from network interfaces in your VPC. This tool helps identify whether the traffic is reaching the intended destination and whether there are any connectivity issues at the network level . Network Access Control Lists (NACLs): Network ACLs are used to control inbound and outbound traffic at the subnet level. By reviewing the rules in the NACLs, you can determine if they are blocking traffic between the application servers and the database servers. Misconfigured NACLs are a common cause of connectivity issues.
