Hands-on lab - creating placement groups

“

- [Instructor] Let's learn how to create three different types of placement groups Before we begin, what are placement groups, and what are they used for? Placement groups in Amazon EC2 give us control over the placement of instances within a cluster to meet specific needs, like low latency or high throughput. We determine the placement of instances across physical hardware to optimize performance or fault tolerance, depending on the selected strategy. There are three types of placement groups, Cluster, Partition, and Spread. A Cluster achieves low latency by packing instances closely together within an Availability Zone. This placement type is used for high performance computing applications and workloads requiring fast data exchange, such as big data analysis or machine learning. It can achieve higher throughput and lower latency because of the proximity of the instances, but it comes with a high risk of correlated hardware failures. A Partition distributes instances across logical…
