Implement Auto Scaling for Amazon ECS
In this lab, you’ll practice scaling ECS containers and ECS instances. When you’re finished with this lab, you’ll have an ECS cluster with EC2 instance and Service Autoscaling configured.
Terms and conditions apply.
Challenge
Check the Deployed Globomantics Site
Start by viewing what you’re working with. In this task, you will be viewing the web page you will be scaling.
Challenge
Create Scale Up CloudWatch Alarms for Request Count
Scaling rules for both ECS and EC2 must be based on a CloudWatch alarm. You now need to create alarms to monitor ELB request count as the basis for ECS Service Auto Scaling.
Challenge
Create CloudWatch Alarm for ECS Reservation
Scaling rules for both ECS and EC2 must be based on a CloudWatch Alarm. As your ECS Services add more tasks, you will need more instances to host those tasks. You will create an alarm for ECS reserved memory as the basis for EC2 Auto Scaling.
Challenge
Create ECS Service Scaling Rules
With the alarms now set up, now we can configure scaling rules. The first set of rules you’ll configure will allow ECS to provision additional Docker containers based on the Requests made to the load balancer.
Challenge
Create EC2 Auto Scaling Rules
The second set of rules you’ll configure will allow EC2 Autoscaling to provision additional EC2 instances containers based on the ECS Cluster memory reservation.
Challenge
Test Your Autoscaling Rules
Your rules should now be ready to go! You can now test these rules and simulate a large number of requests to your application.
Provided environment for hands-on practice
We will provide the credentials and environment necessary for you to practice right within your browser.
