Overview

Auto Scaling automatically adjusts computing resources based on your business cycle

Auto Scaling is a service to automatically adjust computing resources based on your volume of user requests. When demand for computing resources increase, Auto Scaling automatically adds ECS instances to serve additional user requests, or alternatively removes instances in the case of decreased user requests.

This service is available free of cost. You will be only charged for the standard cost of adding additional ECS resources.

Product Details

Auto Scaling is an Alibaba Cloud service that integrates with your business cycle to automatically adjust computing resource based on your volume of user requests. Auto Scaling also integrates with Server Load Balancer and Cloud Monitor to ensure uninterrupted service and a streamlined maintenance.

Elastic Scale-Out: During peak periods, Auto Scaling automatically adds additional computing resource to the pool.

Elastic Scale-In: When user requests decrease, auto-scaling automatically releases ECS resources to cut down your costs.

Elastic Self-Health: When an unhealthy instance has been detected, the auto-scaling service automatically replaces the instance with a new one to ensure uninterrupted service.


Benefits

Flexible

  • Intelligent scheduling to support various scenarios.
  • Automatically adjusts computing resources according to various scaling policies.
  • Supports manual scale-in and scale-out, which offer you flexibility to control resources manually.

Automatic

  • Automatic surveyance of health status.
  • Automatically create or release ECS resources after scaling policy is triggered.
  • Automatically configures load balancer and RDS whitelist.

Scale Mode

Scheduled Mode

Configure scheduled tasks, and add or remove ECS instances with a fixed time window. Can be combined with dynamic mode.


Dynamic Mode

Based on CloudMonitor metrics (ie. CPU and memory ratio), dynamically add or remove ECS instance/s.


Fixed Mode

The “minimal size” setting allows you to employ the minimal ECS instances required to support business-as-usual levels of activity.


Auto-config SLB and RDS

When adding or removing ECS instances, the service automatically attaches or detaches instances to the Server Load Balancer, and adds these servers to the white list of RDS instances.



Note

Auto Scaling is subject to the following constraints:

  • Applications that deploy Auto Scaling ECS instances must be stateless and horizontally scalable. ECS instances created by Auto Scaling cannot be used to save application status (ie. session status) or related data (ie. databases and logs). This is because Auto Scaling automatically releases ECS instances. Status information can be saved to an independent state server, database (ie. RDS), shared cache (ie OCS), or centralized log storage (ie. SLS).
  • Each user can only create a limited number of scaling groups, scaling configurations, scaling rules, scaling ECS instances, and scheduled tasks.
  • Note: Auto Scaling uses its best effort to ensure you are notified of the complete resources of normal scaling. However, due to insufficient ECS instance inventory, long startup time, and other issues, the full resources of scaling may not be displayed. Thank you for your understanding.


Features

Auto Scaling

According to customer business needs, automatically increase or decrease ECS instances.

Support SLB Configuration

When adding or releasing ECS instances, the service automatically attaches or detaches the instances to the Sever Load Balancer.

Support RDS White List

When adding ECS instances, the service automatically adds instance IPs to the white list of RDS instances. Likewise, when releasing ECS instances the service automatically delists instance IPs from the white list.

This included transaction requests that were transferred to servers located over 1,000 kilometres away. Alibaba Cloud’s Server Load Balancer was able to provide uninterrupted service during the peak sales event without missing a single transaction.


Product Details

Server Load Balancer (SLB) is a ready-to-use service that seamlessly integrates with Elastic Scaling Service (ECS) to manage varying traffic levels without manual intervention. SLB is configured above ECS instances to receive incoming traffic first. The SLB then distributes incoming traffic across multiple ECS instances, detects unhealthy or unsafe instances and routes traffic to healthy and safe instances only. This enables you to build highly scalable and robust applications. Importantly, the SLB ensures high availability of your applications by eliminating any single-point-of-failure, and protects from SYN flood and DDoS attacks.

SLB can also be integrated with a Virtual Private Cloud (VPC). You can create an internal cloud load balancer to route traffic using private IP addresses within your VPC. To learn more about VPC click here
