Gregor Hohpe, Google Inc.

Gregor Hohpe is a software architect with Google, Inc. Gregor is a widely recognized thought leader on asynchronous messaging and service-oriented architectures. He co-authored the seminal book "Enterprise Integration Patterns" (Addison-Wesley, 2004), followed by "Integration Patterns" and "Enterprise Solution Patterns", both published by Microsoft Press. He was nominated a Microsoft MVP (Most Valuable Professional) Solution Architect for his contributions to the developer community and recognized as an active member of the patterns community by the Hillside Group. In 2005, Joel Spolsky selected Gregor's article "Starbucks Does Not Use Two-phase Commit" for his "Best Software Writing" (APress).

Gregor speaks regularly at technical conferences around the world. He likes to cut through the hype surrounding service-oriented architectures and captures nuggets of advice in the form of design patterns that can help developers avoid costly mistakes.

Presentation: ""Hooking Stuff Together" - Coupling, Messaging, and Conversations"

Session: Enterprise Systems

Time: Thursday 15:30 - 16:15

Location: Ballroom Le Grand 3

Abstract: As monolithic applications are quickly going the way of the mainframe dinosaur (no, not extinct, but relegated to specialized niche applications), we can expect to spend more time connecting services and components than developing new ones. Will this make developers obsolete because business analysts use the latest drag-and-drop tools to wire up components? Is coupling really so bad? Why is REST popular? Do we need distributed transactions? This talk describes the constraints of connected systems design and presents common design patterns to address some of the challenges.

Presentation: "Software Visualization and Model Generation"

Session: Lean and Agile Software Development

Time: Thursday 16:30 - 17:15

Location: Ballroom Le Grand 1

Abstract: Models are often viewed as something you create during design time and use to generate code. What if we turn the approach up-side-down and generate models from code? Humans are very good at recognizing patterns in images, making visualizations a valuable tool, for example to recognize dependencies or data flow. This is particularly true for dynamic, loosely coupled systems that are often less explicit and evolve over time. Once you have generated a model you can take things a step further and run checks and validations against it. Visualizations can also be used to plot out source code metrics over various dimensions to detect potential ?hot spots? in the application that may require special attention. This talk applies the concepts of visualization and model generation to a broad range of usage scenarios, such as asynchronous messaging, software components and object-oriented applications.

Presentation: "Google & the Cloud: GData, Mashup Editor, AppEngine"

Session: Cloud Computing

Time: Friday 11:15 - 12:00

Location: Ballroom Le Grand 3

Abstract: Google has a lot more to offer than Web search and driving directions, providing over 30 APIs and developer tools at code.google.com. This talk shows the type of applications you can build on top of this platform, explains our design philosophy, and how to integrate Google's services with other Web 2.0 platforms.
