title: how should i architect aws lambda to support parallel process in batch model?
body: <p>i have an aws lambda function to do some statistics on over 1k of stock tickers after market close. i have an option like below.</p>
  
  <ul>
  <li>setup a cron job in ec2 instance and trigger a cron job to submit 1k http request asyn (e.g. <a href="http://xxxxx.lambdafunction.xxxx?ticker=" rel="nofollow noreferrer">http://xxxxx.lambdafunction.xxxx?ticker=</a> to trigger the aws lambda function (or submit 1k request to SNS and let lambda to pickup.</li>
  </ul>
  
  <p>i think it should run fine, but much appreciate if there is any serverless/PaaS approach to trigger task </p>
