BPEL Cookbook: Best Practices for SOA-based integration and composite applications development

This book is not just another generic set of Service Oriented Architecture (SOA) best practices with only general recommendations and advice: instead it's a unique cookbook that shows you how SOA applications are built using best practices that are proven in 10 real-world scenarios. The book consists of three sections. The first two sections will "inspire" you. They showcase real-life projects on BPEL-based integration and development of composite applications. You'll see that SOA is a reality today, learn what successful implementations are like, and how SOA can work for you right now. It will encourage you to take a plunge into the world of services and test-drive SOA yourself. If you are already in the middle of an SOA implementation, these sections will offer you fresh insight into your current approach, help you to deal with specific business challenges, and make sure what you do is in line with the best practice. The third section will "equip" you with BPEL techniques to build better SOA applications. These techniques represent the practical implementation of best practice, with code snippets ranging from development to administration of an SOA application. They are generic enough to be applied in any of your existing projects yet specific enough to enable you reap the full benefits from your SOA implementation.
