title: How to do cross-application with serverless AWS
body: <p>I have two different applications in AWS, deployed by two serverless config files.
  In the first one, I need to read the data from the DynamoDB of the second one.</p>
  <p>serverless.yml n°1 :</p>
  <pre><code>service:
    name: stack1
  app: app1
  org: globalorg
  </code></pre>
  <p>serverless.yml n°2 :</p>
  <pre><code>service:
    name: stack2
  app: app2
  org: globalorg
  </code></pre>
  <p>If I put the 2 services in same app, I can access to the 2nd one with a line like this in iamRoleStatements :</p>
  <pre><code>Resource:
      - ${output::${param:env}::stack2.TableArn}
  </code></pre>
  <p>But if they are not in the same app, I have &quot;Service not found&quot; error when I try to deploy.
  How can I do this cross-application communication ?
  Thanks</p>
