title: aws dynamodb free tier practical limit
body: <p>As per <a href="https://aws.amazon.com/dynamodb/pricing/" rel="noreferrer">AWS Dynamodb pricing</a>
  it allows 25 read capacity units which translates to 50 GetItem requests per second ( with eventual consistency and each item being less than 4kb).</p>
  
  <blockquote>
    <p>Free Tier*</p>
    
    <p>As part of AWS’s Free Tier, AWS customers can get started with Amazon
    DynamoDB for free. DynamoDB customers get 25 GB of free storage, as
    well as up to 25 write capacity units and 25 read capacity units of
    ongoing throughput capacity (enough throughput to handle up to 200
    million requests per month) and 2.5 million read requests from
    DynamoDB Streams for free.</p>
  </blockquote>
  
  <p>How does this translate to online web site? If more than 50 users make GET calls at the same time, do the requests gets throttled ? and eventually 400 response is returned? Does it mean free tier practical limits are, during bursts if 100 users log in the site and make GET calls at same time, we may see 400 responses from DynamoDB. Is this valid conclusion?</p>
  
  <p>I understand that there may hot be 100 requests per <strong>every</strong> second. But if the site has active users of more than 200 at any time, does Dydnamodb free tier still work?</p>
