Guided Lab: Creating Placement Groups – 3 types

Description

Placement groups in Amazon Elastic Compute Cloud (EC2) give you control over the placement of instances within a cluster to meet specific needs, like low latency or high throughput.

Depending on the workload type, you can create a placement group using one of these placement strategies:

  • Cluster – Packs instances closely together within an Availability Zone to achieve low-latency network performance for high-performance computing (HPC) applications that require tightly coupled node-to-node communication.
  • Partition – Instances are distributed across logical partitions to ensure that groups of instances in one partition do not share hardware with groups of instances in different partitions. This approach is commonly used by large distributed and replicated workloads like Hadoop, Cassandra, and Kafka.
  • Spread – Strictly places a small group of instances across distinct underlying hardware to reduce correlated failures.

Objectives

In this lab, you will:

  • Understand the concept of Placement Groups
  • Differentiate the Types of Placement Groups
  • Create the Cluster, Partition, and Spread partition groups in the EC2 console
