maximum amount of instances, subnets and route tables per vpc

Hi, you will get the precise information for you specific AWS account by going to Service quota and checking the values for the services that you need.

It's located on your console at https://us-west-2.console.aws.amazon.com/servicequotas/home?region=us-west-2# (adapt with your region)

Go there and check the values. If insufficient, you can request quota increase on those console pages.

For 12'000 parallel instances and 6'000 subnets, you will very probably need to request such quota increases.

Also, depending on your architecture, you may need additional quota extension: Internet gateways, route tables, etc.

Hi there!

Here are a few data points about VPC and route tables:

• VPC: 5/region --> Subnet: 200/vpc
• Route tables: 200/vpc --> Routes: 50/vpc

Amazon EC2 provides different resources that you can use. These resources include images, instances, volumes, and snapshots. When you create your AWS account, we set default quotas (also referred to as limits) on these resources on a per-Region basis. The reason I can't provide numbers like in the VPC case is because these vary per region and instance family.

I'd suggest you check your Service Quotas Console to review exactly what your current quotas are. From there you can request an increase if these don't meet your needs, just make sure you explain your use case fully so AWS has all the information they need to validate your request.

I hope this helps.
