This topic describes the different ways to create an ECS instance and their applicable scenarios. You can choose a method to purchase and create an instance based on your requirements.
Method | Scenarios |
Quick purchase provides instance types with four preset configurations and multiple packages. You can purchase a ECS instance in just a few minutes. This is the simplest method and improves configuration efficiency. | |
You can flexibly select configurations such as the billing method, image type, instance type, storage, bandwidth, and security group to meet your business requirements. | |
If you have preferred configurations for operating systems and applications, you can first create a custom image. Then, you can create an instance from the custom image to improve configuration efficiency. | |
You can use a community image to quickly deploy an ECS instance with a suitable operating system, applications, and data. This improves configuration efficiency. | |
If you need an instance with the same configuration as an existing one, you can create a new instance with that configuration. This improves the efficiency of horizontal scaling in specific scenarios. | |
You can quickly create an identical or similar instance by cloning a source instance. This method is useful for scenarios such as copying a staging environment, scaling applications, disaster recovery and backup, migration, and upgrades. Cloning improves the reliability, scalability, and efficiency of your services. | |
You can create a launch template in advance. After you configure the template, you can use it to create instances with one click. This method is fast and convenient. | |
Use the Auto Provisioning Group API to create ECS instances in batches | To create many pay-as-you-go instances, you can call an API operation to create them. This method is more efficient. |
