Application Scenarios

Application Scenarios

You can choose and configure different images to meet the deployment requirements.

Creating a Private Image Using an ECS

You can create private images using existing ECSs and create ECSs using private images in batches, facilitating service migration and deployment. Figure 17-1 shows the scenario. IMS in this scenario has the following advantages:

  • Private images can be created using ECSs, enabling flexible service migration.
  • Services can be deployed quickly and in batches.
  • The data durability is high, preventing data loss.

It is recommended that you use IMS together with ECS and AS.

Creating a Private Image Using an External File

An existing service cloud image can be imported to the cloud platform. Currently, VHD, VMDK, QCOW2, and RAW images are supported. You can pre-specify a private image as needed and use the image to create ECSs in batches. This allows you to deploy and upgrade your application systems in a uniform way and improve maintenance efficiency. Figure 17-2 shows the scenario architecture. IMS in this scenario has the following advantages:

  • Private images files can be imported and services can be migrated flexibly.
  • Services can be deployed quickly and in batches.
  • Together with AS, IMS can improve service processing capabilities.
