I seen some questions on an Org that is very sensitive about total amount of money spent on EC2s and have very predictable workload
Among the options are
Ask aws support to limit the instance types the account can create
Use IAM to limit the amount of EC2 each user can create
Reserve 100% the EC2 capacity needed
and some other unrelated options
If you have to choose 2, what would you choose?
I don’t know if Amazon will perform the first option for you, but you can accomplish that yourself with Config rules.
I don’t think option 2 is possible.
Option 3 is not necessarily the best choice. Personally, I’d always work as hard as possible to leverage Spot Instances in almost any EC2 scenario.
Noooooooo….Set up Budgets via the billing dashboard. Also make sure your organization has established a Tagging policy, and ensure that you have activated billing-related Tags in your billing dashboard. That will allow you to filter your budgets and custom Cost Explorer reports by those Tag values.
