Praise for 100 SOA Questions:
“In this book, Kerrie and Ali truly capture the essence of SOA and its benefits to your Business and IT Deployments. Businesses today are desperate to be more nimble and innovative while reducing costs–a tricky proposition. SOA enables companies to reach these goals by tightly aligning the business and IT around the business processes, breaking those processes into reusable business and IT services, and allowing the underlying business and IT infrastructure to be more nimble in supporting the business goals. Effective SOA deployments also lay the groundwork for Cloud formations that can deliver even greater flexibility and cost saving to the business. This book clearly shows that a visit to the land of SOA and Cloud should be on every CxO’s bucket list for their own business.”
–Daniel A. Powers, VP Amazon Web Services Sales
“100 SOA Questions is a must-read for business and IT users who are interested in improving business innovation and agility. Based on their real-world experiences from hundreds of global customer engagements, Kerrie Holley and Ali Arsanjani do an outstanding job of explaining the multiple facets of SOA and providing a prescriptive approach to help readers incrementally unlock value from rigid business processes and antiquated application silos.”
–Manoj Saxena, IBM Executive and Tech Entrepreneur
“In order for IT systems to be successful in today’s world, they must be correct, complete, and extensible. For a long time we have had systems that are point-intime complete, partially correct, and minimally extensible. Kerrie and Ali get to the heart of the matter when they speak to us about the DNA of a Service-Oriented Architecture. It has been my experience in working with them that their focus in defining granularity, composability, and loose coupling from the viewpoint and with the help of the business stakeholders is much more than the cliché, ‘aligning IT with the business,’ would lead you to believe.”
–Manny Bonet, Software Architect
“It is the underpinning infrastructure of a system that determines ultimate flexibility and the ability to scale change to keep pace with rapidly changing global markets. Through Kerrie and Ali’s simple, clear, and comprehensive articulation of the Service-Oriented Architecture approach, I can see that systems must pass through the maturing that SOA brings in order to leverage design methodologies of the future. Those who don’t will be destined to revisit SOA. Great work, gentlemen, in showing us, in such a real world way, the differentiator needed to fight the fight in an ever-leveling technology playing field.”
–Robert Mansell, Vice President, Payments & Settlement Systems, PayPal
“This book, written by prominent IT architects Kerrie Holley and Ali Arsanjani, shows a deep and clear understanding of the SOA paradigm for real business starting from the ground up. It will add a strong contribution both for technical and business people in terms of mutual understanding of SOA implementation to solve real life problems of today’s enterprise. This book should be ‘A must’ to have it at each IT architect’s desk.”
–Alexei Chirokikh, Ph.D., CIO, Gazprombank (OJSC)
“In 100 SOA Questions, Kerrie Holley and Ali Arsanjani have presented an up-to-date, vendor-independent explanation of Service-Oriented Architecture suitable for IT executives, as well as the broader audience of business stakeholders and architects. Sufficiently detailed while not being overly technical, 100 SOA Questions is a book I can heartily recommend to participants in the Licensed ZapThink Architect course.”
–Jason Bloomberg, Managing Partner, ZapThink LLC
“Having known the authors for the better part of the past decade, I can think of no better stewards for all that is pure and good with SOA. Through absolute dedication to their craft, Holley and Arsanjani have been at the forefront of SOA IP, crafting best practices, tools, methodology, and thought leadership in ways both theoretical and practical. This book does the impossible by giving you a glimpse of the magnitude of sheer brain power focused on an incredibly relevant and important topic to both Business and IT. Use it wisely.”
