Architect IBM® WebSphere® Applications for Maximum Performance, Security, Flexibility, Usability, and Value Successful, high-value WebSphere applications begin with effective architecture. Now, one of IBM’s leading WebSphere and WebSphere Portal architects offers a hands-on, best-practice guide to every facet of defining, planning, and implementing WebSphere application architectures. Joey Bernal shows working architects and teams how to define layered architectural standards that can be used across the entire organization, improving application quality without compromising flexibility.
Bernal begins by illuminating the role of architecture and the responsibilities of the architect in WebSphere applications and SOA environments. Next, he introduces specific architectural techniques for addressing persistence, application performance, security, functionality, user interaction, and much more.
Bernal presents a series of sample architectures drawn from his work with several leading organizations, demonstrating how architectures can evolve to support new layers and changing business requirements. Throughout, his techniques are specific enough to address realistic enterprise challenges, while still sufficiently high-level to be useful in diverse and heterogeneous environments.
Coverage includes
• Choosing persistence frameworks that serve business requirements without excessive complexity
• Avoiding persistence-related problems with performance, security, or application functionality
• Designing and deploying effective middle layers and dependent libraries within WebSphere Application Server
• Using WebSphere mechanisms and architectural techniques to avoid common security attacks such as SQL injection
• Improving performance with WebSphere Application Server caching, including Distributed Maps and Servlet/JSP fragment caching
• Using presentation frameworks to provide fast, robust, and attractive user interaction
• Incorporating portals that provide a standardized framework for merging multiple applications

Mr. Bernal helps to lead the Software Services team in many areas, including application architecture and design, performance, and assisting clients with their cross-brand challenges that leverage WebSphere Portal. By its inherent nature of being a platform to integrate applications at the desktop, WebSphere Portal projects require significant cross-brand expertise. All WebSphere Portal projects have products from multiple brands, and many have products from all five brands in the solution. Specifically, he works to reduce the challenges presented by the cross-brand nature of WebSphere Portal projects, especially in the use of newer technologies such as the integration of WebSphere Portal with services-oriented architectures.
Prior to joining IBM, Mr. Bernal was the director of IT for an incentive and performance improvement company. Mr. Bernal was also the lead technical advisor and architect of multiple high-profile Internet and intranet applications for several Fortune 500 companies.
