A vpc virtual private cloud is a virtual network that s specific to your environment.
That s because the microservices that constitute an app rely heavily on the internal network to communicate. Monitoring internal traffic is therefore key to understanding how the app is performing. Amazon virtual private clouds or aws vpc provide you with your own virtual private data center and private network within your aws account.
Vpc flow logging records information about the ip data going to and from designated network interfaces storing this raw data in amazon cloudwatch where it can be retrieved and viewed. Vpc flow logging is critical for security and compliance in your aws cloud environment. Vpc flow logs track all inbound and outbound traffic to and from instances in your amazon web services virtual private cloud.
