Default limits for your region are configured properly. All AWS resources are configured with limits by default. As your AWS EKS size grows based on the max and desired size of Kubernetes settings on AWS and K8S components of your stack, you might run into some resource limits. For example, you are initially limited to launching 20 Amazon EC2 instances at any one time and a maximum VPC size of /16 (65,536 IPs). If you would like to increase these limits, pleasecreate and submit the support case on your AWS account.. the AWS default limit for the number of VPCs in a region is 5, as stated inAWS documentation on VPC limits. To see the default limit values for all your EC2 resources within a given region:
Log into your AWS console.
Navigate to Services > EC2
Once in EC2, on the left-hand side menu panel, click on the limits
This will show you all default limits for your AWS resources. Any specific limit can be raised by submitting a ‘Service limit increase’ request with AWS.
