Background information
Before you read further in this topic, you must be familiar with the following information:
Classification and naming of instance types. Familiarize yourself with the instance family categories, naming conventions of instance types, and differences between instance families. For more information, see Classification and naming of instance types.
Instance type metrics. For information about the metrics of instance types, see Instance type metrics. You can also call the DescribeInstanceTypeFamilies and DescribeInstanceTypes operations to query the instance families and the details of all instance types provided by ECS.
Instructions for selecting instance types based on your business scenarios. For more information, see Instance type selection.
After you determine an instance type for your use case, you may need to learn about the following information:
Regions in which the instance type is available for purchase. Instance types that are available for purchase vary based on the region. You can go to the Instance Types Available for Each Region page to view the instance types available for purchase in each region. Alternatively, you can call the DescribeRegions and DescribeZones operations to query the available regions and the zones in a specific region.
Estimated instance costs. You can calculate the price of instances that uses different billing methods in the Price Calculator. You can also call the DescribePrice operation to query information about the most recent prices of ECS resources.
Instructions for purchasing an instance. You can go to the ECS instance buy page to place a purchase order for instances.
You may be concerned about the following information:
Retired instance families. If you cannot find an instance type in this topic, the instance type may be in a retired instance family. For information about retired instance families, see Retired instance families.
Supported instance type changes. Before you change the instance type of an instance, check whether the instance type can be changed and identify compatible instance types. For more information, see Instance types and families that support instance type changes.
