# EC2 Placement Group

An EC2 Placement Group is a logical grouping of Amazon EC2 instances that influences how they are placed on underlying hardware. It helps optimize performance or availability depending on the chosen strategy: Cluster for low-latency and high-throughput workloads, Spread for distributing instances across hardware to reduce correlated failures, and Partition for isolating groups of instances across partitions.
