ECS instance types of the x86 architecture - Elastic Container Instance

This topic describes how to specify Elastic Compute Service (ECS) instance types of the x86 architecture to create an Elastic Container Instance (ECI) pod.

Supported instance type families

ECS instance type families of the x86 architecture fall into two categories based on whether they are suitable for enterprise scenarios: enterprise-grade families and shared families.

x86-based enterprise-level computing 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	x86-based enterprise-level instance family
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, and hfg5 hfc8i, hfc7, hfc6, and hfc5 hfr8i and hfr7
Big data instance families	d1 and d1ne
Instance families with local SSDs	i2 and i2g

x86-based shared computing 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.

Note

Some of the preceding instance type families use local disks, such as i2 and d1ne. To mount local disks, you must configure a volume. For more information, see ECS instance types that use a local disk.

Configurations

You can add the Kubernetes. aliyun.com/eci-use-specs annotation to the pod metadata to specify ECS instance types. The following code provides an example in YAML format.

apiVersion: apps/v1
kind: Deployment
metadata:
  name: test
  labels:
    app: test
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      name: nginx-test
      labels:
        app: nginx
        alibabacloud.com/eci: "true" 
      annotations:
        k8s.aliyun.com/eci-use-specs: ecs.c6.large. ecs.c5.large # Specify a maximum of five ECS instance types at a time. 
    spec:
      containers:
      - name: nginx
