SOA is a framework that integrates siloed applications so that their functionality can be accessed as services on a network. Web services are the most common way to implement SOA.
Microsoft Asia-Pacific region public sector technology strategist James Whittred said the Malaysian government had shown a lot of interest in SOA and that education would be key to its widespread adoption.
He said Microsoft would continue to play a role in helping to raise awareness of the benefits of SOA among organisations.
E-filing from LHDN is a good example of online web services. But why we need to colaborate with Microsoft. SOA can be implemented without direct colaboration with microsoft. Government can deal indirectly with Microsoft. Web services suppose to be open platform. User can use Microsoft platform software or other third party software. There no necessity to coloborate directly with Microsoft Corporation.
