Amazon Elastic Compute Cloud (EC2) is a web service that provides resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers. EC2 allows you to launch virtual servers, known as instances, and configure security and networking, as well as manage storage.
When attempting to launch an EC2 instance, you may encounter an error message stating InvalidInstanceType. This error indicates that the instance type specified is not recognized or is unavailable in the selected region.
The InvalidInstanceType error occurs when the instance type you have specified does not exist or is not supported in the region you are trying to launch the instance. Each AWS region supports a specific set of instance types, and not all instance types are available in every region.
Ensure that the instance type you are trying to use is correctly spelled and exists. You can find a list of available instance types in the AWS EC2 Instance Types documentation.
Instance type availability varies by region. Check the Regional Product Services page to confirm that the instance type is available in your desired region.
If the instance type is not available in your region, consider selecting a different instance type that meets your requirements and is supported in the region. Use the AWS Management Console or AWS CLI to modify your instance launch configuration.
Once you have identified a valid instance type, update your launch configuration. If using the AWS CLI, you can specify the instance type with the --instance-type parameter:
aws ec2 run-instances --image-id ami-12345678 --count 1 --instance-type t2.micro --key-name MyKeyPair
By following these steps, you should be able to resolve the InvalidInstanceType error and successfully launch your EC2 instance. Always ensure that you are using a valid and supported instance type for your selected region to avoid this issue in the future.
