Answer 1

In distributed computing, distributed objects are objects (in the sense ofobject-oriented programming) that aredistributed across different address spaces, either in different processes on the same computer, or even in multiple computers connected via a network, but which work together by sharing data and invoking ...

Answer 2

Answer:

1. How distributed computing systems are going to be evolved in future and explain it briefly mentioning/citing with proper references.

The current computing/software paradigm isn’t scalable since it relies on “shared memory”, but most physical systems work on message passing, so to make progress you have to persuade folks to give up one for the other. You can lower the bar on the transition by making SMP work as a programming paradigm on top of message passing -

2.Write limitations of following technologies   a.XML  b. SOA   c. SOAP    d. RESTful  

 Service Oriented Architecture (SOA), is most frequently used term, but people do not have deep knowledge that what Service Oriented Architecture actually is. They get confused and relate it with cloud computing. In the last few years, cloud computing has grown into one of the emerging technologies in IT industry. The cloud computing is dynamically scalable resources, where SOA is the concept of loosely coupled services. Each service is independent of the other; together they can form a complete system. This paper gives an overview of cloud computing and SOA and also proposes a solution that SOA should be merged with cloud to eliminate the SOA limitations. Combining cloud with SOA will enhance the availability and reliability of SOA and will reduce its messaging overhead.
