When using an ECS cluster with EC2 instances, what maintenance tasks should you perform on the EC2s?

ECS clusters do not use EC2 instances.

You should not directly manipulate the EC2 instances created by ECS. AWS will automatically update these instances.

The instances created by ECS do not have patches that need to be applied; however, you should make sure your containers contain any important security updates.

Refresh the cluster with instances built from the latest ECS AMI.

When using AWS for research and development ahead of a planned migration, how do you prevent unexpected increases or spikes in the billing?

Use the billing dashboard to create a cost budget. Input the max amount you want to be charged each month. Any charges that occur over this amount will cause AWS to automatically suspend those resources.

If you are using the AWS free tier, you will have to confirm the usage of any service that goes over the AWS free tier limits.

Using the root AWS account, activate IAM access to the billing information for the account. Make sure your IAM users have the BillingFullAccessGroup policy. Then from the billing dashboard, check the accrued charges once a day.

Using the root AWS account, enable Billing Alerts in the user preferences. Then use CloudWatch to create a billing alarm and set a threshold to a specific dollar amount for your estimated monthly charges.
