title: AWS EventBridge pricing for cron events
body: <p>I would like to schedule triggering my Lambda function.<br>
  AWS EventBridge allows me to do this (e.g. by creating cron based rule) but I don't understand <a href="https://aws.amazon.com/eventbridge/pricing/" rel="nofollow noreferrer">its pricing model</a>.<br>
  It states "All state change events published by AWS services are free" but <strong>I'm not sure if an event fired by EventBridge (generated by EventBridge rule) relates to this free one</strong>. Probably not.<br>
  If it's not free, then <strong>how 30 events per month will be billed if pricing is based on million of events</strong>.</p>
  
  <p>Googling didn't help. Do you have ideas how 30 events will be billed?</p>

  <p><strong>Update</strong>:<br>
  While experimenting I found that we should not pay for 30 events per months but it's not clear why. Probably less than million of events are free.</p>
