  So CloudWatch logs are not free, but there's no up-front cost and the price is
  cheap to get started. Here are few things you can pay attention for the
  CloudWatch logs.
</p>
<h2>Free tier 5GB Data</h2>
<p>
  Lots of AWS Service will automatically be sending logs to CloudWatch logs, for
  example, Lambda function, ECS, or CodeBuild. You can, of course, turn off the
  logs depending on the service. 5GB should be a good amount of free tier if you
  start as an individual.&nbsp;
</p>
<h2>Paid Account is cheap</h2>
<p>
  For paid account, or after the free tier, you'll charge $0.03 per GB for
  storage. If you store 100GB of logs, will cost you $3 per month. It also
  charges when collecting data, or analyze the data, both are $0.5 per GB and
  $0.03 per GB.
</p>
<h2>Delivery to S3 is Cheaper</h2>
<p>
  Seems like if you store the logs to S3 might be cheaper base on the AWS'
  documentation, for instance, if you store the VPC flow logs to CloudWatch logs
  will cost you $0.50 per GB, but if you choose to deliver to S3, then will cost
  you $0.25 per GB.&nbsp;
</p>
<h2>Cleanup the un-used CloudWatch logs</h2>
<p>
  To check the CloudWatch logs, first, you go to CloudWatch at AWS, then click
  the logs section then you'll see all the Log Groups, sometime you might have
  some un-used logs, AWS services already deleted but logs are still there, you
  might want to clean it up once a while, seems like by default all logs'
  retention is never expired at default.
</p>
<h2>Conclusion</h2>
<p>
  CloudWatch logs are cheap to get started, don't forget data ingest and analyze
  the logs will cause you money, also remember to delete some unused to save
  money.&nbsp;
