SOA or in full, Service Oriented Architecture is
a technology that shares resources on a network
within the workplace, to be accessed when needed
by the users. Unlike the other system
architectures, SOA is more flexible and in that
the resources that are being shared are connected
and can be made use of at the same time. It is
the best choice for a network of especially great
numbers, in that there many users on the network.
Also if there are users who will connect
remotely, it is a good approach to use spread the
resources. By using SOA, each of the services
provided will make use of the software system
individually, while making use of the same
system. As much as it sounds wasteful and over
bearing on the system, it is not. Given that the
services on the SOA are making use of the system
that they are on, they are only producing
different outcomes to that of each user however
it is the same service or action.

An example of SOA is the use of ATMs (Automated
Teller Machines). The concept is that the
individual (remote) users can each have access to
the banking services, in a kind of unique way to
them. Now when we apply the SOA approach, the
users will make the use of the Retrieve balance
on the system, however, the results will be the
balance of their own bank accounts. This is the
same if a company makes an internet based
request. In the end the same system is being made
us of, because in the end it is the same
Retrieve balance service on the SOA. One of
the major plus points of the SOA, is that, should
the service on the system need to be revised,
they can easily be applied, without having to
tear down the entire system and the reaffix it
back when the changes are made. For example, in
the same ATM situation, should the users have,
perhaps two accounts, perhaps a savings and
current account, and previously the service could
only present the balance for the account that is
asked for the user would have to perform the
same service twice. Considering there are charges
incurred for each interaction with the ATM, it
would cause issues.

Therefore, when the bank wishes to apply a
Retrieve balance for all Accounts function
within the service, it can be easily derived from
the Retrieve balance and applied just as fast.
The services are not so closely attached that
they would fall apart if they are required to be
edited. A new approach of presenting the SOA
recently is in the use of XML language. This is
because the user only requires a browser that can
make use of the XML script, and nothing more.
This approach to deliver SOA is useful because
there are no latest technology that is required
to use the services. The user can simply log in,
and make the requests at the click of a button.
The computer will deal with the requests in the
background because it can easily interact with
the services because the same lingua franca is
being used. Image Source Maintec Posted by
