Alibaba Cloud Series — EP 2: Comparing ECS Instance Types in Container Service for Kubernetes (ACK)

From previous section, we have learned about how different CNI models in a ACK cluster.

In this section, we will learn which ECS instance types we can choose for different workloads for ACK clusters. Let’s begin

In Alibaba Cloud, there are many ECS instance types based on workload characteristics such as:

• General Purposes
• Compute Optimized
• Memory Optimized

We can categorise different workloads and instance types that are available for AKS clusters as the table:

You can see that you can use:

• ecs.g6 for general purpose workloads such as websites and application servers
• ecs.gn5, ecs.sn1 for machine learning applications and gpu workloads
• ecs.r6 for any database servers

Now we learned how we can choose instance types for different workloads in ACK clusters. In the next section we will walkthrough how we can install Istio to manage traffics and telemetry on ACK clusters.
