Queries the details of all instance types or a specific instance type provided by Elastic Compute Service (ECS).
Operation description
Usage notes
Take note of the following items:
- MaxResults specifies the maximum number of entries per page. The maximum value of this parameter is changed from 1600 to 100. As of November 15, 2023, only 100 can be used as the maximum value of MaxResults. If you called the DescribeInstanceTypes operation in 2022, you can use 1600 as the maximum value before November 15, 2023. If you do not specify NextToken when you call the DescribeInstanceTypes operation, only the first page of results that contains up to 100 entries is returned. If you want to retrieve more results, specify NextToken to perform paged queries, or specify filter conditions to filter results.
- We recommend that you specify MaxResults and NextToken to perform paged queries. The first time you call the DescribeInstanceTypes operation, set MaxResults to limit the maximum number of entries that can be returned in a single call. If the number of entries to return exceeds the specified MaxResults value, the response includes a NextToken value. You can set NextToken to the return value and specify MaxResults in your next request to DescribeInstanceTypes to retrieve the next page of results.
- The DescribeInstanceTypes operation is used to query only the specifications and performance information of instance types. To query instance types that are available in a specific region, call the DescribeAvailableResource operation.
- To use special instance types such as instance types that are unavailable for purchase, submit a ticket.
