Note: The Active Load Balancers limit check is currently inaccurate. Although the limit applies to the total number of load balancers, the check counts only Classic Load Balancers and does not count Application Load Balancers.

Note: Data for EC2 On-Demand instance limits is available only for these AWS Regions:

Asia Pacific (Tokyo) [ap-northeast-1]

Asia Pacific (Singapore) [ap-southeast-1]

Asia Pacific (Sydney) [ap-southeast-2]

EU (Ireland) [eu-west-1]

South America (São Paulo) [sa-east-1]

US East (N. Virginia) [us-east-1]

US West (N. California) [us-west-1]

US West (Oregon) [us-west-2]

Note: Trusted Advisor does not currently track regional limits for EC2 On-Demand instances. By default, this limit is 20 on-demand instances per account, per region.

In cases where you have reached this regional limit, you might be unable to launch new on-demand instances even though Trusted Advisor will indicate that you have not reached any of your per-instance type limits within that region. For more detail on EC2 On-Demand limits, please refer to How many instances can I run in Amazon EC2.

We are constantly working on including more services in the Service Limits check. Your feedback is really helpful to us.
