Service Overview 1 What Is Image Management Service?

Issue 12 (2020-03-30) Copyright © Huawei Technologies Co., Ltd. 1

1 What Is Image Management Service?

Overview

An image is a server or disk template that contains an operating system (OS) or service data

and necessary application software, such as database software. Images are categorized into

public, private, Marketplace, and shared images.

Image Management Service (IMS) allows you to manage the lifecycle of images. You can

create ECSs or BMSs from a public, private, or shared image. You can also create a private

image from an ECS or external image file.

Image Types

Images are classified as public, private, Marketplace images, and shared images according to

their visibility. Public images are provided by the cloud platform, private images are those

you created, and shared images are private images that other tenants shared with you.

Figure 1-1 illustrates the relationships among different types of images.

https://www.huaweicloud.com/en-us/product/ims.html




Figure 1-1 Image types

Image Type Description

Public image A public image is a standard, widely used image. It contains an OS and

preinstalled public applications and is available to all users. Public

images are highly stable and authorized. You can configure the

application environment or related software as required.

Public images support the following OSs: Windows, CentOS, Debian,

openSUSE, Fedora, Ubuntu, EulerOS, and CoreOS.

For more information about public images, see Managing Public Images.

Private image A private image is an image that contains an OS or service data,

pre-installed public applications, and the owner's private applications. It

is visible only to the user who creates it.

A private image can be a system disk image, full-ECS image, or data disk

image.

https://support.huaweicloud.com/en-us/usermanual-ims/ims_01_0101.html




Image Type Description

System disk image: contains an OS and pre-installed application

software for running services. You can use a system disk image to

create ECSs and migrate your services to the cloud.

Data disk image: contains only the owner's service data. You can also

use a data disk image to create EVS disks and migrate your service

data to the cloud.

Full-ECS image: contains an OS, pre-installed application software,

and service data.

Shared image A shared image is an image shared by another tenant with you. For more

about shared images, see Sharing Images.

Marketplace

image

The Marketplace is a store where you can purchase third-party images

that have the OS, application environment, and software pre-installed.

You can use the images to deploy websites and application development

environments with a few clicks, and no additional configuration

operation is required.

IMS Functions

IMS provides:

Public images that use common OSs

Creation of a private image from an ECS or an external image file

Public image management, such as searching images by OS type, name, or ID, and

viewing the image ID, system disk size, and features (such as user data injection and disk

hot swap) supported by the image

Private image management, such as modifying image attributes, sharing images, and

replicating images

Creation of ECSs using an image

For details about the preceding functions, see 4 Features.

Access Mode

The public cloud provides a web-based service management platform (management console).

You can access ECSs through HTTPS-compliant application programming interfaces (APIs)

or the management console. These two access modes differ as follows:

API

If you need to integrate IMS into a third-party system for secondary development, use

APIs to access the IMS service. For details, see Image Management Service API

Reference.

Management console

You can perform other operations provided by IMS on the management console. If you

have registered an account on the cloud platform, log in to the management console and

choose Image Management Service on the homepage.

If you have no account, register an account by following the instructions in Common

Operations on the Management Console.

Service Overview 2 Product Advantages


2 Product Advantages

IMS provides convenient, secure, flexible, and efficient management of images. Image

deployment involves customizing the OS, applications, drivers, and settings on a single

computer and creating an image of it, then automatically deploying this image to other

computers.

Saving Time and Effort Simultaneously deploying an image on multiple cloud servers takes much less time and

makes this task much easier.

A private image can be created from an ECS, an external image file, or the system disk

or data disks of an ECS or BMS.

Private images can be transferred between accounts, regions, or cloud platforms through

image sharing, replication, and export.

Secure Public images use Huawei EulerOS and mainstream OSs such as Windows Server,

Ubuntu, and CentOS. These OSs have been strictly tested to provide secure and stable

services.

Image files are stored in multiple copies on Object Storage Service (OBS), providing

high data reliability and durability.

Private images can be encrypted through envelope encryption of Key Management

Service (KMS), ensuring data security.

Flexible You can manage images through a management console or API.

You can use a public image to deploy a general-purpose running environment, or use a

private image or a market image to deploy a customized environment.

IMS can meet your requirements such as server migration to the cloud, migration

between clouds, and server running environment backup.

Unified IMS provides a self-service platform for simplifying image management and

maintenance.

IMS allows you to batch deploy and upgrade application systems, improving O&M

efficiency and ensuring consistency.


Service Overview 2 Product Advantages


Public images comply with industry standards. Only initialization components are

pre-installed. Kernel capabilities are provided by well-known third-party vendors to

facilitate image migration between cloud platforms.

Comparison Between Image-based Deployment and Manual Deployment

Table 2-1 Image-based deployment and manual deployment

Item Image-based Deployment Manual Deployment

Time required 2 to 5 minutes 1 to 2 days

Complexity Quickly create ECSs by using

public images, Marketplace

images, or existing solutions.

Select an appropriate OS, database,

and application software according

to your business requirements.

Then, install and commission them.

Security You only need to identify sources

of shared images. The images

such as public, private, and

market images have been strictly

tested to ensure security and

stability.

The security depends on the skills

of the R&D or O&M personnel.


Service Overview 3 Application Scenarios


3 Application Scenarios

Migrating servers to the cloud or between clouds

Create images (in VHD, VMDK, QCOW2, or RAW format) from existing servers and

import the images to the cloud platform for enterprises to migrate business to the cloud.

Provide image sharing and cross-region image replication to enable migration of ECSs

between accounts and regions.

Deploying a specified software environment

Using shared images or Marketplace images enables enterprises to quickly build

specified software environments, without having to manually configure environments or

installing software. This is especially suitable for Internet startups.

Batch deploying software environments

Use an ECS with an OS, partitions, and software to create a private image, and then use

the image to create ECSs in a batch. The created ECSs have the same configuration as

the source ECS.

Backing up server running environments

Create an image from an ECS to back up the ECS. If the software of the ECS becomes

faulty, you can use the image to restore the ECS.

Service Overview 8 Permissions Management


8 Permissions Management

If you need to grant different permissions to employees in your enterprise to access your IMS

resources, IAM is a good choice for fine-grained permissions management. IAM provides

identity authentication, permissions management, and access control, helping you secure

access to your HUAWEI CLOUD resources.

With IAM, you can use your HUAWEI CLOUD account to create IAM users for your

employees, and grant permissions to the users to control their access to specific resource types.

For example, some software developers in your enterprise need to use IMS resources but must

not delete them or perform any high-risk operations. To achieve this result, you can create

IAM users for the software developers and grant them only the permissions required for using

IMS resources.

If your HUAWEI CLOUD account does not require individual IAM users for permissions

management, skip this section.

IAM can be used free of charge. You pay only for the resources in your account. For more

information about IAM, see IAM Service Overview.

IMS Permissions

By default, new IAM users do not have any permissions granted. You need to add a user to

one or more groups, and assign policies or roles to these groups. The user then inherits

permissions from the groups it is a member of. This process is called authorization. After

authorization, the user can perform specified operations on BMS based on the permissions.

IMS is a project-level service deployed and accessed in specific physical regions. To grant

IMS permissions to a user group, specify the scope as region-specific projects and select

projects for the permissions to take effect. If All projects is selected, the permissions will take

effect for the user group in all region-specific projects. When accessing IMS, users need to

switch to a region where they have been authorized to use IMS.

You can grant users permissions by using roles and policies.

Roles: A coarse-grained authorization mechanism provided by IAM to define

permissions based on users' job responsibilities. This mechanism provides only a limited

number of service-level roles for authorization. When using roles to grant permissions,

you also need to assign other roles that the permissions depend on to take effect.

However, roles are not an ideal choice for fine-grained authorization and secure access

control.

Policies: A type of fine-grained authorization mechanism that defines permissions

required to perform operations on specific cloud resources under certain conditions. This

https://support.huaweicloud.com/en-us/productdesc-iam/iam_01_0026.html




mechanism allows for more flexible policy-based authorization, meeting requirements

for secure access control. For example, you can grant IMS users only the permissions for

managing a certain type of image resources. Most policies define permissions based on

APIs. For the API actions supported by IMS, see Permissions Policies and Supported

Actions.

Service Overview 9 Basic Concepts


9 Basic Concepts

9.1 Region and AZ

Concept

A region and availability zone (AZ) identify the location of a data center. You can create

resources in a specific region and AZ.

Regions are divided based on geographical location and network latency. Public services,

such as Elastic Cloud Server (ECS), Elastic Volume Service (EVS), Object Storage

Service (OBS), Virtual Private Cloud (VPC), Elastic IP (EIP), and Image Management

Service (IMS), are shared within the same region. Regions are classified into universal

regions and dedicated regions. A universal region provides universal cloud services for

common tenants. A dedicated region provides specific services for specific tenants.

An AZ contains one or more physical data centers. Each AZ has independent cooling,

fire extinguishing, moisture-proof, and electricity facilities. Within an AZ, computing,

network, storage, and other resources are logically divided into multiple clusters. AZs

within a region are interconnected using high-speed optical fibers to support cross-AZ

high-availability systems.

Figure 9-1 shows the relationship between regions and AZs.

Figure 9-1 Regions and AZs

HUAWEI CLOUD provides services in many regions around the world. Select a region and

AZ based on requirements.




Selecting a Region

When selecting a region, consider the following factors:

Location

It is recommended that you select the closest region for low network latency and quick

access. Regions within the Chinese mainland provide the same infrastructure, BGP

network quality, as well as resource operations and configurations. Therefore, if your

target users are on the Chinese mainland, you do not need to consider the network

latency differences when selecting a region.

− If your target users are in Asia Pacific (excluding the Chinese mainland), select the

AP-Hong Kong, AP-Bangkok, or AP-Singapore region.

− If your target users are in Africa, select the AF-Johannesburg region.

− If your target users are in Europe, select the EU-Paris region.

Resource price

Resource prices may vary in different regions. For details, see Product Pricing Details.

Selecting an AZ

When deploying resources, consider your applications' requirements on disaster recovery (DR)

and network latency.

For high DR capability, deploy resources in different AZs within the same region.

For low network latency, deploy resources in the same AZ.

Regions and Endpoints

Before you use an API to call resources, specify its region and endpoint. For more details, see

Regions and Endpoints.

9.2 Common Image Formats IMS supports multiple image formats, and the system uses the ZVHD format by default.

Table 9-1 lists the common image formats.

Table 9-1 Common image formats

Image Format Description Remarks

ZVHD This is a self-developed format. It uses

the ZLIB compression algorithm and

supports sequential read and write.

A universal format

supported by IaaS

OpenStack A format

supported for imported and

ZVHD2 This is a self-developed format. It uses

the ZSTD algorithm and supports lazy

loading.

QCOW2 This is a disk image supported by the A format supported for

https://www.huaweicloud.com/en-us/pricing.html

https://developer.huaweicloud.com/en-us/endpoint





QEMU simulator. It is a file that

indicates a block device disk of a fixed

size. Compared with the RAW format,

the QCOW2 format has the following

features:

Supports a lower disk usage.

Supports Copy-On-Write (CoW). The

image file only reflects the changes of

disks.

Supports snapshots.

Supports zlib compression and

encryption by following Advanced

Encryption Standard (AES).

imported and exported

images

VMDK VMDK is a virtual disk format created by

VMware. A VMDK file represents a

physical disk drive of the virtual machine

file system (VMFS) on an ECS.

A format supported for


images

VHD VHD is a virtual disk file format

provided by Microsoft. A VHD file is a

compressed file stored in the file system

of the host machine. It mainly contains a

file system required for starting ECSs.



images

VHDX VHDX is a new VHD format introduced

into Hyper-V of Windows Server 2012

by Microsoft. Compared with the VHD

format, VHDX has a larger storage

capacity. It provides protection against

data damage during power supply

failures and optimizes the disk structure

alignment mode to prevent performance

degradation of new physical disks in a

large sector.


imported images

RAW A RAW file can be directly read and

written by ECSs. This format does not

support dynamic space expansion and has

the best I/O performance.


imported images

QCOW QCOW manages the space allocation of

an image through the secondary index

table. The secondary index uses the

memory cache technology and needs the

query operation, which results in

performance loss. The performance of

QCOW is inferior to that of QCOW2,

and the read and write performance is

inferior to that of RAW.


imported images

VDI VDI is the disk image file format used by

the Virtual BOX virtualization software


imported images





of SUN. It supports snapshots.

QED The QED format is an evolved version of

the QCOW2 format. Its storage location

query mode and data block size are the

same as those of the QCOW2 format.

However, QED implements

Copy-On-Write (CoW) in a different way

as it uses a dirty flag to replace the

reference count table of QCOW2.
