Specify x86-based ECS instance types to create an elastic container instance - Elastic Container Instance

This topic describes how to specify x86-based Elastic Compute Service (ECS) instance types to create an elastic container instance.

Supported instance families

x86-based ECS instance families are divided into enterprise-level instance families and shared instance families based on whether they are designed for enterprise scenarios.

Enterprise-level instance families

x86-based ECS instance types are based on the x86 architecture. Each vCPU corresponds to a hyper-thread of a processor core. They deliver stable performance and are suitable for scenarios such as enterprise-level applications, database systems, video encoding and decoding, and data analysis.

Category	Instance families
General-purpose instance families	g8a, g8i, g7a, g7, g6e, g6a, g6, g5, sn2, and sn2ne
Compute-optimized instance families	c8a, c8i, c7a, c7, c6e, c6a, c6, c5, sn1, and sn1ne
Memory-optimized instance families	r8a, r8i, r7a, r7, r6e, r6a, r6, r5, se1ne, and se1
General compute category instance families	u1
Compute-intensive instance families	ic5
Instance families with high clock speeds	hfg8i, hfg7, hfg6, hfg5, hfc8i, hfc7, hfc6, hfc5, hfr8i, and hfr7
Big data instance families	d1 and d1ne
Instance families with local SSDs	i2 and i2g

Shared instance families

Shared ECS instance types are suitable for small and medium-sized websites and individuals. Compared with enterprise-level ECS instance types, shared ECS instance types emphasize the sharing of resource performance to maximize resource utilization. In this case, the stability of computing performance cannot be ensured, but the cost is reduced.

Local disk considerations

Some of the preceding ECS instance families, such as i2 and d1ne, use local disks. If you want to specify ECS instance types that use local disks to create an elastic container instance and attach a local disk to the elastic container instance, specify the volume-related parameters. For more information, see Specify ECS instance types that use local disks to create an elastic container instance.

Configuration description

API

When you call the CreateContainerGroup operation to create an elastic container instance, you can use the InstanceType parameter to specify ECS instance types. The following table describes the parameter. For more information, see CreateContainerGroup.

Parameter	Type	Example	Description
InstanceType	String	ecs.c6.xlarge,ecs.g6.xlarge	The ECS instance types. You can specify up to five ECS instance types at a time. Separate multiple instance types with commas (,).

Console

When you create an elastic container instance in the Elastic Container Instance console, you can click the Specify Instance Type tab in the Container Group Configurations section and select x86-based ECS instance types based on your business requirements.

You can select the number of vCPUs and a memory size or select a specific ECS instance type to filter ECS instance types. You can also filter ECS instance types by selecting a processor in the Processor column.

If you want to use an x86-based ECS instance type that uses a local disk to create an elastic container instance, we recommend that you use the API because the console does not support attaching local disks.
