title: AWS Instance with Best Network Performance
body: <p>I have a spring boot REST service which uses Tomcat container in AWS ( instance type m4.xlarge, same region, non public facing, nothing on-prem, using private IPs). Our performance testing showed network latency, and scaling out hasn't shown any improvement and so I am also thinking of scaling up. In order to get maximum network benefit and throughput, which instance type will benefit me the most? </p>

  <p>Will using a placement group help to boost TPS of my Rest API.</p>
