Explanation

Cluster Placement Group: This type of placement group is designed to provide low-latency network performance and high throughput by grouping instances within a single Availability Zone. It is ideal for applications that require tightly coupled node-to-node communication. When launching EC2 instances, specify the option to launch them in a cluster placement group. This ensures that the instances are physically located close to each other, reducing latency and increasing network throughput. Low-Latency Communication: Instances in a cluster placement group benefit from enhanced networking capabilities, enabling low-latency communication. High Network Throughput: The network performance within a cluster placement group is optimized for high throughput, which is essential for HPC workloads.
