Application
Service Provider (ASP) - is to provide web access to software
previously distributed as local applications. Depending on the
type of application, it may require the development of an entirely
different browser-based interface, or merely adapting an existing
application to use different presentation technology. These
programs allow the user to pay a monthly or yearly fee for use of
a software application without having to install it on a local
hard drive.
IP Applications -
Over the last few decade, as the global TCP/IP Internet has grown,
hundreds of new applications have been created. These programs
enable a myriad of different tasks and functions to be
accomplished, ranging from implementing essential business tasks
to pure entertainment, by users who may be in the same room or on
different continents.
It would be impossible to try to describe every possible TCP/IP
application, would be pointless to even try, so we will be
advertising applications that grab our imagination. However, of
all the TCP/IP applications, there are a small number that are
widely considered to be “key applications” of TCP/IP.
IP Applications can be devided into two groups:
The first group can be described to use file and message transfer
applications; this group is the largest, as it contains many of
the applications we consider central to TCP/IP networking, such as
electronic mail, file transfer and the World Wide Web.
The second describes interactive and remote application protocols, which
are used traditionally to allow a user of one computer to access
another, or to permit the real-time exchange of information.
'Cloud' Virtual Data Centres -
Billions are being invested in Cloud computing and
data center architectures.
Applications that are hosted in the cloud require massively scalable data
centers to be able to deliver the always-on availability and
performance required. It means the compute resources of these data
centers must operate at huge scales if the cost benefits to the
user are to be realised
IBM defines cloud computing as: "Where users can gain access to
their applications from anywhere through their connected devices.
The applications reside in massively scalable data centers where
compute resources can be dynamically provisioned and shared to
achieve significant economies of scale. A strong service
management platform results in near-zero incremental management
costs when more IT resources are added to the cloud.'
While Google and Amazon say they already operate cloud data centers,
another big player currently constructing cloud data centers
around the world is Microsoft.
