The document discusses the evolving architecture of web applications over the past two decades. It describes how in the early years, websites were mostly inward-facing with innovation focused on front-end standards. However, in recent years web applications have become more complex as they are deeply interlinked at the service level, relying on specialized third-party services. The talk will provide an overview of this emerging architecture and how it is changing what application providers can offer.

2. In the past few years, the world of web applications has changed dramatically. Some of the changes have been obvious and fully chronicled: The rise of rich internet applications, the reliance on advertising models? But while the world has noted these user-facing changes, another, more profound, shift has been occurring with less fanfare: Web applications have become deeply linked, not just in the HTML but at the service level. As a result, web applications are growing exponentially more complex and functional, and new opportunities are rising for service providers AND application developers. In this talk, I'll give an overview of the emerging architecture of the web, talk about how its evolution is changing the breadth of what application providers can offer, and dive into some real lessons from building out an internet-scale virtual economy service.
