What Is VMware Image Management Service?

A VMware image is an Elastic Cloud Server (ECS) template that contains software and mandatory configurations. Specifically, an image contains an OS and may also contain proprietary software and application software, such as database software. By interconnecting VMware Service with VMware vCenter, VMware images can be centrally managed on ManageOne. There are public images, private images, and frequently used images. Table 40-4 describes the image types.

Image Type

Description

Public image

Public images are the default images provided by VMware Service or those created by administrators on the management console. These images are visible to all users. A public image is a standard, widely used image. It contains an OS and preinstalled public applications. You can configure the applications or software in the public image as needed.

Private image

Private images are user-created. A private image is visible only to the user who creates it. A private image contains an OS, pre-installed public applications, and users' private applications. Using a private image to create a VMware ECS eliminates the need to repeatedly configure VMware ECSs. Private images can be created from VMware ECSs.

Frequently used image

You can add private images and public images as frequently used images.

VMware Image Management Service (IMS) provides the self-service image management capability. You can apply for a VMware ECS using a public image, private image, or frequently used image. You can also create a private image using an existing VMware ECS or an external image file.

Advantages

VMware IMS allows you to create private images as required and use the images to apply for VMware ECSs for flexible management. In addition, you can create VMware ECSs in batches using private images. This facilitates unified deployment and upgrade of application systems and improves maintenance efficiency.

Application Scenarios

VMware IMS allows you to create private images as required and use the images to apply for VMware ECSs for flexible management. In addition, you can create VMware ECSs in batches using private images. This facilitates unified deployment and upgrade of application systems and improves maintenance efficiency. Figure 40-10 shows the details.

Figure 40-12 VMware IMS workflow

  1. VDC administrators or VDC operators apply for VMware images from the ManageOne operation plane. VMware Service delivers the operation requests to VMware IMS for processing.
  2. CoreTask processes tasks transferred by VMware IMS.
  3. API Gateway distributes the requests for vCenter systems.

Related Services

VMware ECS: You can use a VMware image to create a VMware ECS or convert a VMware ECS to a VMware image. Figure 40-13 shows the details.

Accessing and Using VMware IMS

FusionCloud provides a web-based service management platform, which users can access with the ManageOne operation plane or API.

  • ManageOne operation plane

    Users can use the ManageOne operation plane to access the cloud service. If you are a VDC administrator, VDC operator, or have the operation rights for the cloud service, you can directly log in to the ManageOne operation plane and choose this cloud service on the Product List or Console menu.

  • API

    If you want to integrate the service into a third-party system for secondary development, you can access the service using API. For details, see the API reference of the cloud service in FusionCloud 6.3.1.1 API Reference.
