Overview
1.1 Application Virtualization Overview Traditional distributed application deployment becomes more and more complex with continuous cost increase. IT personnel must continuously update new application versions and install patches for thousands of devices. Therefore, applications of the latest versions are not installed on many user devices. In addition, applications and data stored on user devices are insecure and conflict with each other, which may cause the device to slow down or even break down. IT service cost increase and production efficiency reduction cannot ensure data security and high-quality user experience and meet service requirements. Quick infrastructure increase and great increase of IT hardware and applications push virtualization development. Increasingly larger IT systems are distributed wider and wider, which causes complex and difficult management; however, service, management, and monitoring pressures for IT control enhancement are increasing. Application virtualization helps organizations improve service efficiency, enhance employee mobility, comply security and monitoring and management specifications, new market development, service outsourcing, and service continuity. Taking an IT application client centralized deployment platform as a core, application virtualization aims to enable unified computing and running of user applications and data on cloud platforms in a mode transparent to users and ensure that users can enjoy the same experience in accessing local applications and that users can obtain the same computing results.

1 Overview
Centralized architecture improves performance of applications connected to devices over any networks or applications that run on any devices. New applications can be delivered to users in a few seconds, the applications can be updated in one-off mode, and update programs are released for users in a timely manner. This helps IT departments to allocate resources, ensuring optimal performance of key users and applications.
Centralized application delivery based on service modes Centralized application deployment reduces application management costs, and centralized control and secure access improve security. Centralized architecture frees IT personnel from installing or managing applications on distributed terminals. Instead, applications and server mirrors are stored, maintained, and updated in data centers in one-off mode, and then delivered to users as required. This simplifies IT management, avoids application conflicts, implements real-time updates, and reduces repair and upgrade necessity.
Any device and anywhere Users can access applications by using any devices anywhere in self-service mode. Users can access applications and data in secure and timely manner by using any clients, operating systems, or devices, such as a desktop PC, portable computer, thin client, iPhone, or Android phone.
Improved information security Centralized application delivery enables the most secure application delivery architecture. Data is stored in data centers. Little control information and screen updates performed by the mouse and keyboard are transferred through a network. IT administrators can assign permission to access, print, and store applications to specific applications and user groups, ensuring security of important information.
1.2 Comparison Between Mainstream Desktop Cloud Solutions and Selection Suggestions Widely used mainstream desktop cloud solutions include virtual desktop infrastructure (VDI) and server-based computing (SBC). Centralized management desktop based on virtual machines (VMs) refers to traditional VDI, which enables Windows XP, Windows 7, or Vista desktop to run on a server. For example, using server virtualization technologies, one physical server can concurrently run 60 Windows 7 desktops, and then these desktops are transferred to terminals of 60 users. The users find virtual desktops on the terminals, but real desktops run in a data center. Desktop virtualization VDI is applicable to scenarios in which applications are complex and users have more requirements on personalization. In certain application scenarios, SBC is also a good choice for application virtualization because:
Applications need to be installed only once. During application virtualization, multiple users share the same application instances. Therefore, applications only need to be updated at one place, and the applications of all users can be immediately updated.
Costs are reduced. In an SBC environment, one physical server supports concurrent access of hundreds of users.
Application compatibility problems are inevitable because VDI can release server desktops only, desktops are basic units for load balancing, and all necessary applications

must be installed on each server. SBC can install incompatible applications on different servers and release them for a same user.
Compared with VDI, SBC is applicable to mobile terminals, such as mobile phones, because SBC enables application windows to be displayed on screens of mobile phones, bringing good experience.
The following table compares the mainstream desktop virtualization technologies. VDI
SBC Shared session desktop
Shared session application
User experience
Users have dedicated operating systems.
Users have different desktops that are based on a same operating system.
Users can only see shortcut icons of the published applications. User experience is the same as that of local applications.
Hardware resource usage
Hardware resource usage is high because a VM is provided for each user. Each VM occupies CPU, memory, storage, and I/O resources.
Less resources are required because each user only occupies the resources required by a virtual desktop.
The least resources are required because each user only occupies the resources required by running the desired application.
Software requirement
Software requirements are high because VDI software and license VDA of virtual operating systems must be purchased.
Less software is required because only SBC software license and Microsoft Remote Desktop Services (RDS) license must be purchased.
Less software is required because only SBC software license and Microsoft RDS license must be purchased.
Deployment cost
The server, storage performance and capacity requirements are high; therefore the deployment cost is high.
The deployment cost is low because user intensity is high.
The deployment cost is low because user intensity is high.
Management difficulty
Management difficulty is high because user data and systems are deployed on servers, and therefore VDI software and background infrastructure components must be maintained.
Management difficulty is low because only shared operating systems and released applications need to be managed and SBC software and background infrastructure components must be maintained.
Management difficulty is low because only shared operating systems and released applications need to be managed and SBC software and background infrastructure components must be maintained.
1.3 SBC Benefits for Customers Centralized application deployment and IT management optimization ensure that all clients do not need to be maintained, maintenance workload of IT departments is reduced, and deploying new applications and upgrading application software speed up. Good application access experience and network bandwidth reduction: SBC has low requirements for network bandwidth. In normal state, each user occupies about dozens of

kbit/s bandwidths. Branches can reach satisfied speeds and performance, reducing costs on private lines. High data transfer security: During application access through desktop protocols, actual service data is not transferred over networks, and only mouse and keyboard actions on clients and screen updates are transferred. This ensures centralized, unified, and secure data. Client PC reuse and device update cost reduction: Virtualization-based application access reduces performance requirements on client PCs, prolongs device updates, and saves costs. Low project implementation risks, few impacts on existing customer systems, and no change of user habits: Existing systems do not need to be reconstructed for deploying the SBC solution, but only new SBC servers need to be deployed. Original operation GUIs and use modes are retained so that no extra user operation training is necessary. Mobile office anywhere at any time: Users can use various terminals (including mobile phones, tablets, and laptops) to access service applications over networks anywhere at any time. This improves office flexibility and efficiency.

2.1.1.1 Infrastructure Components
Web Interface (WI): WIs provide web login pages for users. After a user sends a login request to a WI, the WI forwards user login information (encrypted username and password) to HDC, and displays a VM list or application list provided by HDC to the user. In FusionAccess solution, multiple WIs implement load balancing. WIs implement load balancing between HDCs after you set HDC IP addresses on the WIs.
Huawei Desktop Controller (HDC): HDC, a core component of FusionAccess, provisions virtual desktop services or virtual application services, and manages virtual desktops or virtual applications, login to virtual desktops or virtual applications, and VMs or virtual application policies.
GaussDB: GaussDB stores data for ITA and HDC. The data includes information about associations between VMs and users or virtual applications and users, desktop groups, VM naming rules, and scheduled tasks.
IT Adapter (ITA): ITA provides interfaces and a portal for users to manage virtual IT assets, such as creating and assigning VMs or virtual applications, managing VM images and status of VMs or virtual applications, and operating and maintaining virtual desktops.
License: License manages and delivers licenses of the desktop cloud system and can be used to control the number of users accessing the desktop cloud system.

2 Introduction to Application Virtualization Solutions
Virtual application resource pool: It provides shared desktops and virtual applications. Multiple APS Servers are deployed on one server. Based on current test, it is recommended that four to six APSs be installed on one server, and load balancing is implemented between the APSs.
2.2 Application Virtualization Implementation Principle 2.2.1 Typical Service Process of Application Virtualization 2.2.1.1 Application Virtualization Features Depending on Windows Operating System Services Application virtualization depends on Windows operating system features. Understanding Windows components and their functions helps understand the application virtualization implementation principle. Shell and Terminal Services are components provided by Windows, and they are depended by application virtualization.
Shell Shell is a graphical user interface of the Windows operating system. It contains a desktop, Start menu, task bar, special folders, files, and common folders.
RDS RDS is called Terminal Services in Windows Server2008 and earlier versions. It is a Windows operating system component, which allows a user to control remote computers or VMs through a network. Initially introduced in Windows NT 4.0 Terminal Server Edition, RDS improves in each Windows edition from Windows 2002. Since Windows Server 2008 R2 was released in 2009, it is called RDS. Service RDS provides a multisession environment in which end users can obtain and save virtual Windows desktops and execute Windows programs on servers and multiple users can connect to a same server and interact with each other. Multiple users can connect to and control a same server, and desktops and applications are displayed on remote computers. In the latest Windows Server 2008 R2 edition, Microsoft allows users to use their own desktop protocols rather than the original Remote Desktop Protocol (RDP) to perform the access and control. FusionAccess SBC features depend on RDS and support entire desktops and remote applications released based on RDS of Windows Server 2012 R2. HDP is adopted for remote access. Application virtualization quotation includes RDS license quotation because Windows RDS is used.

2 Introduction to Application Virtualization Solutions
Principles for remotely running applications 1.
Set global message hooks on a remote session desktop, monitor behavior of windows displayed on the desktop, and instruct a client to create windows based on the server mode.
2.
The client receives instructions from the server for creating or updating windows rather than displaying the remote session desktop. Then the client instructs the server to specify windows based on operations performed by a user on remote application windows on the client.
3.
Updates on the display area on the remote session desktop are sent to the client, and intersections between the area and remote application windows are updated in a specified window area.
Process for Shell to start an application 1.
A user clicks the icon of an application virtualization program on a client.
2.
Shell receives a request form the client for starting the application.
3.
If the number of applications that have been started exceeds the maximum number specified in policies, a message is displayed on the client.
4.
Shell decrypts the received request and parses HASHID and parameters of the application.
5.
Shell checks whether the user has the permission to start the application and whether application parameters are valid to verify the application to be started. If invalid requests are received multiple times, an attack is considered. If this happens, Shell obtains login information, such as session information, IP addresses, and accounts, and sends such information to the administrator.
6.
An application virtualization system sets the permission to start processes to prevent excess permission from being used to start processes.
7.
The application virtualization system starts the processes. If the startup fails, the system sends the error message to the client.
2.2.1.5 Application Virtualization HDP Supporting Isolation Between Sessions 1.
Mouse and keyboard operations can be isolated by session.
2.
Audio files can be isolated by session.
3.

3 Application Virtualization Scenarios
Application Virtualization Scenarios
3.1 Branch Scenarios 3.1.1 Scenario Description 3.1.1.1 Challenges
Complex system running and maintenance and high cost: Maintenance costs of applications of the C/S architecture increase. Each application modification or update involves updates of each remote client. This requires manpower, material, and capital resources
System security: When branches exchange data with headquarters, real original data is transferred over a network, and such data can be easily intercepted by competitors or hackers. This may cause great loss for enterprise development.
Application access rate: When application systems are integrated into a data center and a client accesses an application system in a traditional mode, the client may be affected by bandwidth and stability problems because the mode for the application to transfer data is different. Access speed in such a mode is low, and the number of branches is increasing, which will also slow down access.
Difficult data centralization: When a branch accesses an application of the traditional C/S architecture, data can only be stored locally to ensure performance, and headquarters cannot understand service situations of the branch in real time.
Questions: 1.
How to install application systems for devices in each branch, remotely maintain and provide support for such systems, and flexibly implement expansion and migration?
2.
How to ensure the remote access speed, network stability, and data transfer security?
3.
How to ensure security of application servers or database servers when users outside headquarters access Huawei application systems?

Deployed applications include the ERP system, E-HR system, and Kingdee K/3 system. Deployment of the application virtualization solution brings customers the following benefits:
Maintenance Maintenance implemented in branches is integrated into headquarters, which reduces maintenance workload. Deployment of new applications speeds up, and headquarters deploy new services for all branches in unified way, which improves efficiency by dozens of times.
Access speed Using desktop protocols to access application systems, each user requires only dozens of kbit/s, reducing application requirements on bandwidth of branches.
System security When accessing application systems over a network, users use desktop protocols for communication, and only keyboard and mouse operations on clients and GUI updates rather than entire data packets are transferred over the network through desktop protocols. Permission (such as access, modification, backup, copy, and print) of each client is specified in desktop protocol policies so that security of application software and data is ensured. Enterprise application systems and database servers are deployed on an intranet, and only APS server addresses need to be published on a public network. This ensures security of enterprise application systems and data.

3 Application Virtualization Scenarios
3.1.2 Solution Advantages
Centralized application deployment and optimized IT management An application virtualization server collects clients of all applications to APSs, which then distribute and manage the clients in centralized mode. No plug-in is required for terminal access, and all clients do not need to be maintained. This reduces maintenance workload of IT departments. In addition, new applications can be quickly deployed, and application software needs to be upgraded only on a few servers.
Support for various clients After installing HDP AccessClient software on a terminal, such as a mobile phone, a user can directly access all background applications. Various desktop OS platforms and mobile phone platforms are supported. Users can access background services and office systems at any time anywhere through any terminals.
High speed HDP, a data transfer protocol dedicated to application virtualization, ensures that all necessary applications are executed on servers, featuring low requirements on network bandwidth. In normal states, each user requires only dozens of kbit/s. This reduces private line costs.
High availability If a network fault occurs, system processes are not interrupted because all applications and data are managed on servers and running status of desktops is automatically stored on the servers. Once the network connection is recovered, all operations can continue. Load balancing is available between APSs. The system automatically loads users to different servers based on policies developed by administrators or loads of each server. Usage of other servers is not affected if any server shuts down, except for the license server.
High security Applications and data are stored on servers, and only updates on server computing screens can be found on clients. Actual data computing ensures data centralization, unifying, and security. Client permission can be set based on policies, including whether desktops can be viewed, printed, or saved to a local directory. This ensures controllable information usage permission.
Low project implementation risks Existing systems do not need to be switched to new systems because the existing systems do not need to be reconstructed for application virtualization solution deployment. New systems can be set up only after new server layers are added to a network. Original operation GUIs and use modes are retained so that no extra user operation training is necessary.

3 Application Virtualization Scenarios
3.2 Scenarios for Separation Between Intranet and Internet 3.2.1 Scenario Description 3.2.1.1 Challenges With quick Internet development, people can obtain more and more efficient information from Internet. This information is helpful to daily work. For example, R&D personnel can obtain functional modules and sample code from Internet to participate in discussion, research personnel can better understand industry development trends on Internet, and marketing personnel can obtain competitor information from Internet to understand real-time market situations. However, Internet helps people obtain more important information but also provides channels for attacks from viruses and worms. How to manage employees to use Internet in security and efficient mode is a challenge for IT personnel.
3.2.1.2 Solution Centralized surfing enabled by application virtualization resolves the problem. PCs on user desktops cannot directly visit Internet. Instead, all Internet access is available only after related applications (such as Internet Explorer, MSN, QQ, and FTP) are publicized on application virtualization servers. Administrators can determine whether users can use special applications based on user accounts. For example, only development personnel can use FTP tools. APS Servers for centralized surfing are managed by administrators, and end users have common user permission only. The following figure shows architecture of the management system for centralized surfing of application virtualization.

Security gateway
Before optimization: All clients can directly access applications on Internet, causing security risks. After optimization: Clients access Internet through the servers for centralized surfing of application virtualization, and administrators assign corresponding permission to users to prevent misuse of P2P software, enable security cache functions, and protect clients from being attacked by viruses. Deployment of the application virtualization solution brings customers the following benefits:
User PCs cannot directly access Internet, and P2P software cannot be installed on APS Servers that can access Internet so that overuse of P2P software is prevented.
User clients will not be attacked by viruses, worms, and Trojan horses from Internet because Internet Explorer runs on APS Servers and common users do not have the permission to download and install Internet Explorer. This avoids most security holes.
Administrators set Internet Explorer security options and install anti-virus software on virtualization servers in centralized mode. The administrators regularly update and scan virus code to prevent system security holes.
Only authorized users can access specific applications. For example, only administrators can specify the users who can use IM software such as MSN and QQ.
Bandwidth is reduced because users cannot proactively or negatively perform operations not specified in policies so that abnormal traffic generated by movie download and P2P can be avoided.

3 Application Virtualization Scenarios
3.2.2 Solution Advantages Security isolation:
Intranet PCs access VMs deployed on Internet, and users can access Internet only by using virtual desktops or applications.
Physical user desktops can access service systems only.
Internet access traffic is separated from service network access traffic.
Data security:
Data in VMs can be transferred to PCs, which cannot copy the data to VMs. This unidirectional transfer ensures data security.
Network transfer protocols enable access to data on terminal clipboards and local disks so that copying and pasting of text, files, and images are managed and controlled, realizing management and control of peripherals.
Centralized data control: Desktops and data are separated from terminals and centrally controlled on the cloud. Only screen refresh information is transferred to terminals.
Controllable virtual channels of peripherals: Each virtual channel can be separately enabled or disabled, such as print control and USB port mapping management.
Unidirectional data flow control: Virtual desktops or applications can be imported into physical servers, but data cannot be written from physical servers to virtual desktops or applications.
Protocol-based encrypted transfer: Desktop protocols adopt the AES128 algorithm by default to encrypt transferred data.
Management of mobile media used by internet: Permission to read, write, and access mobile storage media can be managed and controlled.
Centralized management:
User work environments and data are deployed and managed in centralized mode.
Application permission and data access permission are managed in centralized mode.
Software is upgraded and maintained in centralized mode, and data is stored and backed up in centralized mode.
Personal data and configurations are separated from desktop systems and applications. User data storage space is not affected by desktop update, upgrade, and deletion.
Shielding of threat sources:
Threat sources are reduced and shielded so that risks caused by access to Internet are avoided.
Centralized, standard, and unified permission management is gradually implemented.
Integrity, security, availability, and expansion of service application system architecture are ensured.

3.3 Simple Office Scenarios 3.3.1 Scenario Description 3.3.1.1 Challenges
More and more complex services and applications are used, bringing greater deployment, maintenance, and delivery pressures. This required flexible and efficient deployment and O&M.
How to resolve the problems that service clients must be continuously upgraded and patched? How to ensure data security even though more security products are deployed? How to prevent clients from being attacked by viruses and malicious software?
In large organizations, PCs are used in most traditional office OA scenarios, and PCs occupy large space and consume more power.
Simple OA scenarios indicate that only certain Windows applications are used for office, and there are few requirements on hardware performance of Windows hosts. Such scenarios involve industries such as education, medical care, finance, call centers, airports, and hotels. In such scenarios, if customers can use only certain applications rather than configuring dedicated OSs on PCs, desktop service costs will be reduced.

Deployment of the application virtualization solution brings customers the following benefits:
Mobile office: Administrative and service personnel can handle office work at any time anywhere, which improves work efficiency and customer satisfaction.
Centralized management and flexible deployment: Application virtualization ensures centralized management of office software. Administrators can manage, monitor, and schedule enterprise resources at any time, and deploy one or more application servers in a few minutes. This improves server management and maintenance efficiency, and IT architecture of branches can be easily expanded.
3.4.2 Solution Advantages
Cross-platform access from various smart mobile phones
Various OS platforms and mobile phone platforms are supported so that secondary development is unnecessary for applications to adapt to each collection platform. This reduces system complexity and development workload. Users can access background services and office systems at any time anywhere through any terminals, including smart mobile phones, PCs, and tablets. Agile experience of end users Only updates of running screens of applications on servers are displayed for end users, and such screens are encrypted and compressed, generating little traffic, usually dozens of kbit/s. Low bandwidth consumption ensures smooth use experience of end users. In addition, application clients do not need to be installed on each mobile phone. Instead, administrators can authorize users, who can enjoy the same application user experience that can be enjoyed on PCs on mobile phones. Limited network traffic ensures low network investment, improving system publicity and usability.
Quick and centralized application publication Compared with traditional mobile application solutions, application virtualization publicizes service and office systems of enterprises to ensure more convenient support for mobile terminals, without secondary development. In addition, existing system architecture is not affected.

Service applications and servers exchange data between intranet server clusters of APS Servers and application servers, and actual service data is not transferred to user terminals. This ensures smoothness of service data exchanges and data security. The external vAG gateway provides SSL/TSL encryption for user connections so that data security is ensured during data transfer.
High reliability and stability If a network fault occurs, system processes are not interrupted because all applications and data are managed on servers and running status of desktops is automatically stored on the servers. Once the network connection is recovered, all operations can continue.
Easy system maintenance and management System maintenance workload does not increase even though system functions are added because secondary development is not required. All application software is managed on servers in centralized mode, which reduces manpower and material resources for daily maintenance.

4 Key Application Virtualization Performance Indicators
Key Application Virtualization Performance Indicators
4.1 Key Performance Indicators The intensity of SBC shared desktops is calculated based on VDI VSI test results, and the intensities for heavy, middle, and light loads are determined based on the proportions in a same module of SBC and VDI. Middle load is recommended for SBC shared desktops, but the load can be adjusted based on the actual module and the number of users who use shared desktops. A maximum of three virtual applications are configured for each user, and configured intensity is calculated based on 1.5 times the middle-load module (four or five applications) of a share desktop. Based on performance and costs of single APS Servers, four VMs, each with six vCPUs are configured for two-socket hexa-core servers, six VMs, each with six vCPUs are configured for two-socket octa-core servers, seven VMs, each with six vCPUs are configured for two-socket ten-core servers, and eight VMs, each with six vCPUs are configured to two-socket 12-core servers. 1.5 GB memory is configured for each user. The size of VM system disks is set to 80 GB, and IOPS is configured for five to seven services per user.

5 FAQs
Software compatibility issues in application virtualization scenarios are classified into the following types: −
Compatibility between software and OSs
−
Compatibility between software and multiple sessions
−
Compatibility of software GUI display
The first two types of compatibility issues refer to constraints of software and Microsoft systems, and it is unnecessary to traverse all software. Instead, site deployment POC test software ensures compatibility. The last type of compatibility issues belongs to protocol mechanism compatibility, which requires more attention. For details about SBC software compatibility, see the list of SBC software compatibility.
