AWS AUTOSCALING GROUP DISK ALARM HOW TO

It’s a good practice to enable autoscaling on the services to ensure the application can meet the demand of it’s end users. We also have to be mindful of scaling the application.

AWS AUTOSCALING GROUP DISK ALARM HOW TO

As operators of the cluster, we have to think about how to scale the backend EC2 infrastructure that runs our tasks (of course, this is for EC2 backed tasks, with Fargate, this is not a concern of the operator as the EC2 backend is obfuscated).

But what happens if we need to run more tasks than what we have current capacity to run? Click the ECS Instances tab, and review the current capacity.Īs you can see, we have plenty of capacity to support a few more tasks. Navigate to the console, and select the container-demo cluster. With the current EC2 instances that are registered to the cluster, there is more than enough capacity to run our service. What we did above was deploy a service that runs one task.

Once the service is deployed, take note of the load balancer URL output. Now that we have a capacity provider created, we need to associate it with the ECS Cluster.

managedTerminationProtection: Enable this parameter if you want to ensure that prior to an EC2 instance being terminated (for scale-in actions), the auto scaler will only terminate instances that are not running tasks.

We also set targetCapacity, which determines at what point in cluster utilization do we want the auto scaler to take action.

managedScaling: This is where we enable/disable cluster auto scaling.

autoScalingGroupArn: The ARN of the Auto Scaling group for the cluster autoscaler to use.auto-scaling-group-provider: There is quite a bit here, let’s unpack one by one: name: This is the human readable name for the capacity provider that we are creating.

Let’s look at the parameters and explain what their purpose: The next command is creating a capacity provider via the AWS CLI. We run a couple of cli calls to get the Auto Scaling group details which is required for the next command where we create the capacity provider. We did this earlier in this section when we added the EC2 capacity to the ECS cluster. In order to create a capacity provider with cluster auto scaling enabled, we need to have an auto scaling group created prior. If you get an error that the capacity provider already exists because you’ve created it in the workshop before, just move on to the next step. Site Terms | © 2022, Amazon Web Services, Inc.

It’s easy to get started with AWS Auto Scaling using the AWS Management Console, Command Line Interface (CLI), or SDK. With AWS Auto Scaling, your applications always have the right resources at the right time. If you’re already using Amazon EC2 Auto Scaling to dynamically scale your Amazon EC2 instances, you can now combine it with AWS Auto Scaling to scale additional resources for other AWS services. AWS Auto Scaling makes scaling simple with recommendations that allow you to optimize performance, costs, or balance between them. The service provides a simple, powerful user interface that lets you build scaling plans for resources including Amazon EC2 instances and Spot Fleets, Amazon ECS tasks, Amazon DynamoDB tables and indexes, and Amazon Aurora Replicas. Using AWS Auto Scaling, it’s easy to setup application scaling for multiple resources across multiple services in minutes. AWS Auto Scaling monitors your applications and automatically adjusts capacity to maintain steady, predictable performance at the lowest possible cost.
