    <b>Deploying Concourse with an External PostgresDB:</b>
    <div>
      Concourse v3.6.0 and later no longer manage an internal
      Postgres database with the BOSH release.
      An operator needs to instruct Concourse to connect to one of the following:
      <ul>
        <li>
      An externally-managed Postgres database.</li>
        <li>
      A BOSH-managed Cloud Foundry Postgres release. For more information, see <a href="http://bosh.io/releases/github.com/cloudfoundry/postgres-release">postgres/30</a> in the BOSH documentation.</li>
      </ul>
      You need to configure the <code>postgresql</code> properties of the ATC job for your database.
      For a list of these properties,
      see <a href="https://bosh.io/jobs/atc?source=github.com/concourse/concourse#p=postgresql">postgresql</a> in the BOSH documentation.

    <b>Load Balancing Multiple ATCs</b>
    <div>
      If you anticipate a heavy load on your Concourse installation, you may want
      to consider installing a Load Balancer with multiple ATCs.
