Definitie van Thin Client Computing
Ref: Webopedia – nr 1 online encyclopedia for ICT
From a software perspective... “In client/server
applications, a client designed to be especially
small so that the bulk of the data processing
occurs on the server” ...for example, web based
applications on the Internet.
“Although the term thin client usually refers to
software, it is increasingly used for computers,
such as network computers and Net PCs, that are
designed to serve as the clients for client/server
architectures.”
Thin Client , Client/Server Computing
History of TSO, by Jim Moore.
Networking environment
Client (TSU) – hunk of memory
Dumb Terminal that is slavishly dependent upon
something else to serve its needs
Offloading mainframe development to minicomputers & PCs (emulators, simulators, ...)
File & print servers, database servers
Client/servers applications (TCP/IP)
Distributed databases, application servers,
transaction monitors
DCE, CORBA, DCOM
Java, J2EE, application servers, webservers
Web services (.net, J2EE)
What is a service
Workflow step:
Distribute work to available team
HR system:

Contracts:

Implementation of a service
Open Internet Standards to implement SOA
Web Services
Language Independent (.net / J2EE)
Platform Independent (Java/J2EE)
Data Independent (XML)
App-app communication (SOAP) (Loose coupling)
Both for Microsoft as well as Java based services.

Business Relevance for de Vlaamse
Overheid
Network Computing in order to build a SOA based environment
for the VO in order to introduce the necessary granularity to
enable focus on 'core' business within the Beleidsdomeinen at
the entity level: email, calendar, HR, reporting & data mining,
document management, identity management (IDM), access
control management (ACM)...
Network Computing also enbles a means to build a community
Service Delivery Platform (SDP) environment to facilitate rapid
introduction of new services to support the business.
Facilitate “mobiliteit”, “homeworking” & multiple delivery
platforms.
Cost reduction in the longer term.
Through Thin Client deployment minimise disruption to the
business for application upgrades and new application roll-out.

Thin Client
Do more with less
Virtualisation:
Means of abstracting resources from HW
... driving down costs ...
W/out losing benefits of e-Network
Computing
Facilitating better utilization by using
partitions, domains, containers
Using Grid Computing (decoupling apps
from HW)
Do more with less
From Thin Client to Rich Client
Advantages
Types – software; hardware
Software:
Basic browser Client
Rich Client vs Fat Client
Hardware:
Basic – RDP clients

It took 10 years to realize pervasive
networking and being connected all over the
