Monitor AWS Network with VPC Flow Logs and CloudWatch Metric Filter

Описание: In this AWS tutorial Beginning 2023, we will create a complete AWS VPC network monitoring using VPC Flow Log and CloudWatch Log Groups.
We will also configure a CloudWatch metric filter and a CloudWatch alarm to monitor network traffic.
In this step-by-step AWS tutorial english, we will also create a custom IAM role for publishing VPC flow logs to CloudWatch Logs.
Also, we will be attaching a trust policy, which will allow AWS VPC flow log service to assume the role

Here are the links which we discussed in the lecture:
