  • Savings in Desktop Management

    • Replacing the PCS /Fat clients by Thin clients can save lot of money for Desktop Management.There is no need for patch management for the users. Administrators can deploy, manage and support applications much more easily because they are held on a central server farm and are managed from a single point, simplifying application access and administration. There can be substantial cost savings in help desk/management.

  • Hardware savings with the use of Thin Clients

    • Thin clients do not need a lot of resources (processor, memory, disk). Total Cost of Ownership [TCO] reduced by as much as 50 per cent.Thin clients do not need a lot of resources (processor, memory, disk).Total Cost of Ownership [TCO] reduced by as much as 50 per cent.

  • Savings in Power Costs

    • Compared to regular desktops which consume 300-440 w of power thin clients are very power efficient say 5-20 watts typical.

  • Better hardware utilization

    • Thin clients being a device with very low resources normally work at 80-90% of the capacity all the time. This is unlike a PC which, in comparison, barely uses all of the resources it has at its disposal and it is more likely to be in the range of 2-5%.

  • Higher relaibility

    • Thin Clients do not have local storage and so are not affected by viruses or trojans. They are usually completely solid state with no moving part and low power consumption thus intrinsically less prone to heating and hardware failures.

  • Server Based Computing has better performance

    • This is very subjective but generally true.Servers tend to be better equipped (high-end) than PCs: they have better network connections, they operate under better environments, they have more processing power, more memory and so on. Because in Server Based Computing all the “real” computing is done at the Server (the back-end), you harness the full power of this back-end. The server OS is more secure, server-based computing keeps all the data on the secure servers without it being 'spread out' onto the less secure client computers. It’s easy to make the terminal servers fault tolerant and to perform load balancing thus providing increased availability.

  • Easier Disaster Recovery

    • Since the clients in Server Based Computing environments are thin and hence need no installing or configuring, the client part of any disaster recovery scenario is greatly reduced.

  • Easy Remote Access

    • Since all applications are hosted in one place, remote access to those applications can be implemented relatively easy. All you need is the appropriate client and a secure transport and you can connect to the same Terminal Server as in the office and use your applications in exactly the same way. Users can access their desktop and enterprise applications from anywhere on the network, from home or on the road.Users can access their desktop and indeed any enterprise application from any type of client device including portable devices like PDA , phones etc. Server based computing gives also a new dimension to the small business IT management by enabling remote manageability.

  • Scalability

    • Capacity of the network and the infrastructure can be easily exspanded by simpley adding more servers and clients.

Server based computing is not without its share of drawbacks and there are several advantages that the “traditional” local desktop model has over server based architectures,

Local desktops can be used offline The local desktops can be used offline without connecting to the network . But there are new technologies evolving which allow the user to transfer the "image" to be loaded to the local device and then sychronise later just like in the case of portable devices like PDA etc.

Local desktops to not have a single point of failure Even though server hardware is very redundant, if something happens to your back-end servers in a VDI environment, you’re totally out of luck. Compare that to a traditional desktop environment. If one PC fails, that user is out of luck, but the other users can still work.
