Quick Start on Auto Scaling Group in Alibaba Cloud 

Auto Scaling Group in Alibaba Cloud
This tutorial focuses on creating, enabling, viewing, and disabling scaling groups in Alibaba Cloud. 

 

Alibaba Cloud provides a comprehensive set of global cloud computing services to power Alibaba’s eCommerce ecosystem and other online businesses. Since 2009, Alibaba Cloud has been one of the leading providers in Artificial Intelligence (AI) and cloud computing. Alibaba Cloud offers cloud computing resources and services to thousands of government organizations, developers, and enterprises in more than 200 regions.

An Auto Scaling group is a group of Elastic Compute Service (ECS) instances that are dynamically scaled based on pre-configured scaling rules. A Scaling group allows users to set the minimum and the maximum number of ECS instances, templates used to create ECS instances automatically, and policies for removing ECS instances. Also, users can use a Scaling group to maintain a group of Elastic Compute Service (ECS) instances based on the user’s business requirements. In this tutorial, we will learn about the steps to create, enable, view, and disable a scaling group in Alibaba Cloud. 

 

Prerequisites

  • First, activate Auto Scaling when prompted if the users are using it for the first time.
  • Create a launch template if the user wants to use Auto Scaling groups to create Elastic Compute Service (ECS) instances. 
  • Before the user associates an Auto Scaling group with Server Load Balancer (SLB) instances, ensure that the following conditions are met:

          – The users must have at least one Server Load Balancer (SLB) instance in the Active state. 

          – The Server Load Balancer instance and the Auto Scaling group are in the same region.

          – The SLB instance and the scaling group are in the same Virtual Private Cloud (VPC) if the network type used in the user’s account is VPC.

          – If the network type of the SLB instance is the classic network, the network type of the scaling group is Virtual Private Cloud, and the backend server group of the SLB instance contains       VPC-type ECS instances. In that case, ensure that the ECS instances and the scaling group must be in the same VPC.

          – Users must configure at least one listener on the SLB instance. 

          – Make sure to enable a health check on the Server Load Balancer (SLB) instance. 

  • Before we associate a scaling group with ApsaraDB RDS instances, ensure that the following conditions are met:

         – Users must have at least one Relational Database Service instance in the Running state on their account.

         – The RDS instances and the Auto Scaling group must reside in the same region.
