Final answer:
A cluster placement group is a feature in cloud computing that allows you to logically group instances within the same Availability Zone for improved network performance. It is beneficial for applications that require tight communication between instances.
Step-by-step explanation:
A cluster placement group is a feature in cloud computing that allows you to logically group instances within the same Availability Zone. It helps to provide low-latency network performance and high network throughput for applications running on multiple instances. One example of a cluster placement group is a group of web servers that need to communicate with each other.
By placing instances within a cluster placement group, you can ensure that the instances are physically located close to each other in order to reduce network latency. This can be particularly beneficial for applications that require tight communication between instances, such as distributed databases or high-performance computing workloads.
