A placement group is a logical grouping of instances within a single Availability Zone. Using placement groups enables applications to participate in a low-latency, 10 Gbps network. Placement groups are recommended for applications that benefit from low network latency, high network throughput, or both.<br \/>\nReference:<br \/>\n<a href=\"http:\/\/docs.aws.amazon.com\/AWSEC2\/latest\/UserGuide\/placement-groups.html\" title=\"External link\" rel=\"nofollow noopener\" target=\"_blank\">http:\/\/docs.aws.amazon.com\/AWSEC2\/latest\/UserGuide\/placement-groups&#8230;<\/a><\/div>\n<p><\/strong><\/span> <\/div>\n","protected":false},"excerpt":{"rendered":"<p>What is required to achieve gigabit network throughput on EC2?
