Software such as HP Velocity can address the both latency and packet loss. The point-to-point HP Velocity software analyzes the capacities of the network between the endpoint and provides the ideal protection scheme. When TCP/IP is the transport protocol, HP Velocity can provide up to a 700 percent performance improvement using dynamic buffer management. This is achieved by monitoring network conditions with a sensor and by dynamically selecting the optimal method from the suite of 10 provided by TCP.
4. Investment and maintenance is more expensive than with traditional PCs
The core benefit of thin clients is their ability to reduce total cost of ownership. The majority of the upfront cost is not the device itself, because thin clients are cheaper than traditional corporate PCs. With no moving parts such as hard disks or fans, thin clients generally have a lower failure rate, bringing the cost of maintenance and replacement down dramatically.
More to the point, thin clients do not host their applications, making management and patching updates easier. They are smaller, lighter, cheaper to ship, and easier to install, and they generate less packaging waste.
The principle cost borne by thin computing is the establishment of the data center infrastructure and the capital expense of servers, storage, networking, and virtualization software. While this is a significant cost, when considered with the lifecycle of the equipment, it's competitive with traditional PC upgrade cycle costs.
While evaluating total cost of ownership, you must keep in mind that the cost equation has changed in recent years. Businesses now allow end-users to bring tablets, phones, laptops, and other devices into the office -- and they are supporting these devices. It is no longer a comparison between thin clients with a VDI structure versus a standard desktop or laptop PC. We have seen a major shift in thin-client economics. Customers are now deciding to either rewrite their portfolio as Apple, Android, and/or HTML5 applications, or to provide their current Windows application portfolio to these devices through virtualization. Many customers are selecting the ROI made available from thin computing.
5. Thin clients are a huge power suck
The thin client device, screen, and networking can draw less than 13 watts of power. A child's nightlight draws more. Some models consume as little as 2.5 watts -- even in "awake" mode. Desktops typically have a 250-watt power supply with additional power requirements for a monitor.
