Definitions Desktop Virtualization - Also called client virtualization separates a personal computer desktop from a physical machine using a client-server model of computing Virtual Desktop Infrastructure - By using VDI you allow the IT responsible to switch to remote administration of desktops. One large computer acts as server for desktops and thin clients Remote Desktop Software - RDS is a operating sytem feature allowing applications to be run on a server, while being displayed locally on the device display screen Thin Clients - The most common type of modern thin clients is a low-end computer terminal which concentrates solely on providing GUI to the end-user

Advantages VDI simplifies desktop provisioning, administrative and management tasks, while showing reduced downtimes in the event of server or hardware failures No need to reengineer your applications (compare to SaaS) and applications can quickly be added, deleted, upgraded & patched Go back to centralised computing models with thin clients as users access virtual desktops running in the data center or LAN Using SSO as VDI provides flexibility in performance requirements which allows for unlimited scalable resource allocation at hand Access desktops from any capable device at any time, while desktop security and data protection are centralized, such as backup. Avoid organizations paying steep power and cooling costs for many underutilized PCs
Limitations Some loss of user autonomy and privacy Challenges in setting up and maintaining drivers for printers and other peripherals Difficulty in running certain complex applications, such as multimedia, 3D-graphics,... Increased downtime in the even of serious network failures Reliance on connectivity to corporate or public network Potential security risks if the network is not properly managed Complexity and high costs of VDI demployment and management
Use Cases of Desktop Virtualization with Smart Style Office
SSO for Remote Administration Opportunity Businesses looking for IT support companies to manage, monitor and support user’s desktops Challenge Maximizing your desktop support resources to handle as many customers as possible Solution SSO allows resellers to remotely administer desktops from a central control panel. This includes creation, monitoring, snapshots, uptime, patch management, etc.
SSO for Hosted DesktopsOpportunityBusinesses looking for virtualdesktops that are provisionedfrom a central data centerChallengeOptimizing the economies ofscale in hardware and datacenter investmentsSolutionSSO has almost unlimitedresource scalability and growsdesktop availability when morenodes are added to the cloud
SSO for Desktop Migration Opportunity Business looking to migrate their users to Windows 7 in order to lower system requirements and improve user’s work and online experience Challenge Urgency of the desirable desktop upgrade is stretching IT support resoures Solution SSO allows resellers to set up golden images and fast-track the deployment of desktops for its customers
SSO for Securing Device and DataOpportunityBusinesses remain concerned abouttheir data but allow their users toenter the LAN with netbooks,smartphones, laptops, etc.ChallengeAn operating system will alwaysrequire patching, but a proliferationof devices causes serious securityissues for businesses.SolutionSSO provides flexibility in accessingvirtual desktops from any device,anywhere, but forces centralisationof data, allowing IT support staff toprotect the data and its devices
SSO Supports a Changing WorkforceOpportunityBusinesses provide more flexibilityto their workers. Mobility is importantand young people demand more ITChallengeIT support companies have toprovide a consistent level ofservices to increasinglydemanding businesses Opportunity SSO is in general the preferred virtual desktop infrastructure of many IT support companies. The simplified approach to desktop virtualization addresses security, management, availability and flexibility needs. The latter is important for an ever changing workforce and businesses looking for increased productivity

Reseller Approach High-level overview of the components of Smart Style Office virtual desktop infrastructure and how they come together to a for a complete, end-to-end solution - SSO virtual desktop infrastructure starts with a StarterKit package of 2 SSO nodes, 2 switches, 1 racktivity device, all fully racked and cabled. - SSO comes with all virtualization software and a proprietary Cloud Management Center which is an advanced dashboard to provision desktops as VMs - All virtual desktops are hosted on the SSO nodes running their standard desktop OS; Windows or linux for example - Introduce Mirror Cloud backup agents on all desktops in case you allow workers to store data within their virtual desktop environement - Users can be provisioned with hardware thin clients from Zenith Infotech or software thin clients to connect to their virtual desktops - A remote protocal, like Microsoft Remote Desktop Protocol is used to allow client devices in the desktop environment
