Amazon Virtual Private Cloud (VPC) Flow Logs can now be directly delivered to Amazon Simple Storage Service (S3) using the AWS Command Line Interface (CLI) or through your Amazon EC2 or VPC console. You can now deliver VPC Flow Logs to both S3 and CloudWatch Logs.
Deliver VPC Flow Logs to S3 when you require simple, cost-effective archiving of your log events. Take advantage of the different storage classes of S3, such as Amazon S3 Standard-Infrequent Access, or write custom data processing applications using other solutions, such as Amazon Athena.
Deliver VPC Flow Logs to CloudWatch Logs to monitor your systems and applications. Generate and visualize metrics using Metric Filter Patterns and CloudWatch Dashboards, set up alerts on log-based metrics, or search log events using CloudWatch Logs while solving problems.
