title: Best way to store an application log on AWS
body: <p>In my company we have developed many automation applications that syncs data from and to our platform and third party platforms.</p>
  
  <p>Our applications at this time store logs on Sqlite.</p>
  
  <p>Since we ensure our customers the integrity of the synced data, through an internal frontend, we daily check the logs to catch every possible problem and to proceed (possibly) manually.
  Our internal frontend allow us to filter datetime ranges, the different flow each application can have, and see a full detail of the flow of each execution. </p>
  
  <p>Now we wanto to move the log part of aour application on AWS and I wonder which service is more suitable for our needs. DynamoDB seems good, but it might result in excessive costs if we increase our customer portfolio, CloudWatch is also a choice, but I cannot find an online article that does not concern system or service logs.</p>
  
  <p>Any clue is appreciated.
  Thanks.</p>
