In this IEEE article, authors Stephen Yau and Ho An talk about application development using service-oriented architecture and cloud computing technologies. They also discuss application development challenges like security in a multi-tenant environment, quality-of-service monitoring, and mobile computing.
The Open Group recently published three standards that aid organizations that are building infrastructure-as-a-service offerings and service oriented architectures. In concert, these standards provide expert advice in the form of best practices, questionnaires, and templates for SOA and cloud-scale infrastructure architecture.
OASIS recently announced that v4.0 of the ebXML Registry and Repository standard has been approved. However, in an age where Web Services appear on the wane, REST is taken for granted, and Cloud is on everyone's lips, does ebXML have a role to play?
Governance plays an indisputably important role in maintaining and guiding the implementation of an architectural vision. The advent of cloud computing has changed the architectural landscape affecting the needs and demands of existing governance programs. InfoQ presents a virtual panel discussion with six leading experts on the current state and future of cloud services governance.
SOA and Cloud computing experts discuss relationships between SOA and Cloud computing, principles and technologies they can/should share, the applications that can best leverage combining SOA and Cloud computing and the things that are the most important for Cloud computing success.
Ian Robinson discusses how to implement a hypermedia-driven web application and how to test its workflow giving as example a RESTful web service he built on top of Microsoft’s Web API.
Arnon Rotem-Gal-Oz discusses creating a SOA implementation that maintains a good overall reliability in spite of using smaller and a larger number of components.
Bob Ippolito talks about building web services with the Erlang-based MochiWeb and the differences to the Yaws web server, the strengths of Erlang and Python, and more.
In this interview, Subbu Allamaraju talks about real life issues of RESTful architectures. He also describes a pragmatic approach of adopting the Web as an integration platform and shares his opinion on OAuth.
This is the first edition of what is expected to become a recurring series on InfoQ. The idea behind this minibook is that a number of InfoQ articles and interviews which deal with a particular topic (in this case, REpresentational State Transfer, or REST) are combined together to provide a detailed exploration suitable for both beginners and advanced practitioners.
Composite Software offers a new level of granularity when compared to SaaS (Software as a Service). Composite Software is about enabling "right-sourcing", i.e. move (or keep) arbitrary small or large elements of functionality wherever it is the most cost effective to operate them, not just entire systems. Economically, "right-sourcing" is far more efficient than "outsourcing" and SaaS. The goal of this book is start by understanding today’s software construction processes and technologies and explore why and how it should be evolved to support core composition mechanisms.
This book argues that for SOA to succeed we must move our thoughts away from the implementation technologies and towards the "what" of the business. Using a straight-forward, pictorially driven, methodology the book explains who to discover what the business services really are and how to construct an overall business service architecture.
