What is Thin
Computing? |
| The thin client is a PC with less of
everything. In designing a computer system, there are decisions to be made
about processing, storage, software and user-interface. With the reality of
reliable high-speed networking, we can change the location of any of these
with respect to the others. A gigabit/s network is faster than a PCI bus and
many hard drives, so each function can be in a different location. Choices
will be made depending on the total cost, cost of operation, reliability,
performance and usability of the system. The thin client is closely
connected to the user interface.3
In a thin client/server system, we place the
software for the user interface on the thin client, possibly some
frequently/heavily used application, and a networked operating system and
nothing else. This software can be loaded from a local drive, the server at
boot or as needed. By simplifying the load on the thin client, a thin client
can be a very small, low-powered device giving lower costs to purchase and
to operate per-seat. The server, or a cluster of servers has the full weight
of all the applications, services and data. By keeping a few servers busy
and many thin clients lightly loaded we can expect easier system management,
and lower costs as well as all the advantages of networked computing:
central storage/backup and easier security.
Because the thin client is relatively
passive and low-maintenance, but numerous, the entire system is simpler and
easier to install and to operate. As the cost of hardware plunges and the
cost of employing a technician, buying energy and disposing of waste rises,
the advantages of thin clients grow. From the user's perspective the
interaction is with monitor, keyboard and pointer and changes little from
using a thin client. |

Virtualization Technology (VT) solution |
Virtualization is an abstraction layer
that decouples the physical hardware from the operating system to deliver
greater IT resource utilization and flexibility.
Virtualization allows multiple
virtual machines, with heterogeneous operating systems to run in isolation,
side-by-side on the same physical machine. Each virtual machine has its own
set of virtual hardware (e.g., RAM, CPU, NIC, etc.) upon which an operating
system and applications are loaded. The operating system sees a consistent,
normalized set of hardware regardless of the actual physical hardware
components.
Virtual machines are encapsulated into
files, making it possible to rapidly save, copy and provision a virtual
machine. Full systems (fully configured applications, operating systems,
BIOS and virtual hardware) can be moved, within seconds, from one physical
server to another for zero-downtime maintenance and continuous workload
consolidation.
Virtualization was first introduced in the
1960s to allow partitioning of large, mainframe hardware -- a scarce and
expensive resource. Over time, minicomputers and PCs provided a more
efficient, affordable way to distribute processing power, so by the 1980s,
virtualization was no longer widely employed.
In the 1990s, researchers began to see how
virtualization could solve some of the problems associated with the
proliferation of less expensive hardware, including underutilization,
escalating management costs and vulnerability.
Today, virtualization is in the forefront -
helping businesses with scalability, security and management of their global
IT infrastructure. |
