Creating ESIs

This document introduces how to create Elastic Scheduled Instances (ESIs) on the console. When you create an ESI, you need to complete a reservation first. After that, the system automatically generates an ESI order. During the resource delivery period specified in the order, it automatically creates your instance with the pay-as-you-go billing method.

tip

ESIs are currently only available to accounts that have completed enterprise real-name authentication. How can personal authentication be upgraded to enterprise authentication?

Note

Currently, only the following types of ESIs are available for purchase: General-purpose, Compute-optimized, Memory-optimized, High Frequency General-purpose hfg2, and Local SSD i3s/i2.

For ESIs, a minimum 1-hour consumption policy is implemented. Regardless of whether the instance is released within the first hour after creation, a one-hour bill is issued and the fee is charged. Charges beyond the first hour are based on your actual usage of ESI.

When you associate a project or tag with a newly created reservation order, all instances reserved successfully in this order are automatically associated with the corresponding tag or project.

ESI does not support the deployment set feature.

ESI can only be created from images based on snapshots:

Public images provided by the platform are all snapshot-based and recommended for usage.

If you want to use a custom image to create an ESI, first enable the snapshot service and make sure the image has a corresponding snapshot.

If you want to use a shared image to create an ESI, make sure that the image has a corresponding snapshot.

Procedure

tip

This topic mainly introduces configurations when you create an ESI. For more details of instance configurations, refer to Purchasing an instance by following the wizard.

In the top menu bar, select the region and project of your business.

Click the "Create Elastic Scheduled Instances" button to start purchasing an ESI. At this time, the billing method is "Elastic Scheduled Instances". Do not change this setting.

You can also click the "Create instance" button on ECS console, and select the billing method as "Elastic Scheduled Instances" for purchase.

Refer to Purchasing an instance by following the wizard, and then complete the instance Basic configuration, Network configuration, and Custom configuration.

Click the "Next" button to fill in the reservation information.

Hover over the question mark next to the fee at the bottom of the page to view cost details and discount amounts, including fees for specifications, system volume, data volume, and EIP.

Parameter	Description	Sample value
ESI order name	Fill in the ESI order name.	ESI-Name
Quantity	You need to specify the number of instances to be reserved. By default, one account can use up to 300 vCPUs in an availability zone. To increase your vCPU quota, you can go to the Quota center.Learn more You can purchase a maximum of 500 instances in an order.	1
Delivery time interval	Select the instance delivery time period. For the China (Beijing) region, the time period is within 1 to 8 hours, and for the China (Shanghai) or China (Guangzhou) region, it is within 3 to 8 hours. The time period is precise to the minute, and each interval is 10 minutes. After you select the time, your instances will be delivered within this time period. Upon successful delivery, they will change to the Running state. For example, if the current time is 17:42, the earliest delivery time period for the China (Beijing) region is 18:50–19:00 (one hour later). For the China (Shanghai) or China (Guangzhou) regions, the earliest period is 20:50–21:00 (three hours later). The latest delivery time period, 8 hours after the current time, is 01:40–01:50 (+1 day).	2024-06-12 21:50 - 22:00
Tip on billing	ESIs have a minimum 1-hour consumption policy. Please confirm your understanding of this policy.	-
Agreement	Follow the console guidance to review and confirm the agreements.	-

After you confirm the information is correct, click "Buy now" to go to the application submission page and view whether your service is created.

Click the "Go to Console" button to be redirected to the ESI page to view the newly created order.

At this point, the reservation order has been created. Once the resource delivery time is reached, the system automatically creates the ESI that meets your requirements on the order.
