Advanced Web Services

Web Services And Service-oriented Computing (soc) Have Become Thriving Areas Of Academic Research, Joint University/industry Research Projects, And Novel It Products On The Market. Soc Is The Computing Paradigm That Uses Web Services As Building Blocks For The Engineering Of Composite, Distributed Applications Out Of The Reusable Application Logic Encapsulated By Web Services. Web Services Could Be Considered The Best-known And Most Standardized Technology In Use Today For Distributed Computing Over The Internet. This Book Is The Second Installment Of A Two-book Collection Covering The State-of-the-art Of Both Theoretical And Practical Aspects Of Web Services And Soc Research And Deployments. Advanced Web Services Specifically Focuses On Advanced Topics Of Web Services And Soc And Covers Topics Including Web Services Transactions, Security And Trust, Web Service Management, Real-world Case Studies, And Novel Perspectives And Future Directions. The Editors Present Foundational Topics In The First Book Of The Collection, Web Services Foundations (springer, 2013). Together, Both Books Comprise Approximately 1400 Pages And Are The Result Of An Enormous Community Effort That Involved More Than 100 Authors, Comprising The World’s Leading Experts In This Field.
