Scenario 1:

1) Upload ec2 logs to s3 and then to cloudwatch for security review and monitoring

Scenario 2:

1) Upload ec2 logs to cloudwatch and send data then s3

Scenario 3:

1) Upload ec2 logs to both s3 and cloudwatch simultaneously

Please help me to achieve what is correct way.

You can send the logs to cloudwatch and then use cloudwatch to upload them to S3. Check this solution: https://aws.amazon.com/blogs/mt/how-to-export-ec2-instance-execution-logs-to-an-s3-bucket-using-cloudwatch-logs-lambda-and-cloudformation/
