Hands-On: Creating and Using AWS Placement Groups
Introduction
In this practice session, we’ll walk through the process of creating placement groups in AWS and launching EC2 instances within them. This will help you understand how to optimize performance, availability, and fault tolerance by using different placement strategies.
Step 1: Creating Placement Groups
- Navigate to the AWS EC2 Dashboard
- On the left-hand menu, scroll down to Network & Security.
- Click on Placement Groups.
- Create a Placement Group
- Click Create Placement Group and fill in the details.
Example Placement Groups
| Placement Group Name |
Strategy |
Purpose |
| my-high-performance-group |
Cluster |
High-performance computing, low latency |
| my-critical-group |
Spread |
High availability, failure isolation |
| my-distributed-group |
Partition |
Scalable workloads, fault tolerance |
1. Creating a Cluster Placement Group
- Name:
my-high-performance-group
- Strategy: Cluster
- Why? Ensures low-latency networking by keeping instances close together.
✅ Click "Create" to confirm.
2. Creating a Spread Placement Group
- Name:
my-critical-group
- Strategy: Spread
- Spread Level Options:
- Rack (Default) – Distributes instances across different racks (recommended).
- Host (Outposts only) – Only for AWS Outposts (not needed here).
