ABSTRACT
Computational approaches to problem solving have proven their worth in many fields of science, allowing the collection and analysis of unprecedented quantities of data and the exploration via simulation of previously obscure phenomena. We now face the challenge of scaling the impact of these approaches from the specialist to entire communities. I speak here about work that seeks to address this goal by rethinking science's information technology foundations in terms of service-oriented architecture. In principle, service-oriented approaches can have a transformative effect on scientific communities, allowing tools formerly accessible only to the specialist to be made available to all, and permitting previously manual data-processing and analysis tasks to be automated. However, while the potential of such "service-oriented science" has been demonstrated, its routine application across many disciplines raises challenging technical problems. One important requirement is to achieve a separation of concerns between discipline-specific content and domain-independent infrastructure, so that new services can be developed quickly and existing services can respond effectively to time-varying load. Another key requirement is to streamline the formation and evolution of the "virtual organizations" that create and access content. I describe the architectural principles, software, and deployments that I am and my colleagues have produced as we tackle these problems, and point to future technical challenges and scientific opportunities. I illustrate my talk with examples from astronomy and biomedicine.

Web Scale Computing: The Power of
|
ABSTRACT
Building the right infrastructure that can scale up or down at a moment's notice can be a complicated and expensive task, but it's essential in today's competitive landscape. This applies to an enterprise trying to cut costs, a young business unexpectedly saturated with customer demand, or a research lab wanting to test at scale. There are many challenges when building a reliable, flexible architecture that can manage unpredictable behaviors of today's Internet business. This presentation will outline some of the lessons learned from building one of the world's largest distributed systems, Amazon.com, and the evolution that gave rise to Amazon reselling its infrastructure in the form of Amazon Web Services, allowing anyone to leverage the same robust, scalable, and reliable technology that powers Amazon's business.
BIOGRAPHY
Peter Vosshall is a Vice President & Distinguished Engineer at Amazon.com, where he is responsible for providing technical leadership for a number of teams in Amazon Web Services, as well as for the company as a whole. Mr. Vosshall has over 16 years of industry experience designing, building, and operating large scale, highly available distributed systems. Since joining Amazon in 1998, he has been a key contributor to Amazon's overall software architecture, and has built a number of core enabling technologies for Amazon's distributed architecture, including Dynamo, Amazon's highly available key-value store. Prior to joining Amazon, Vosshall built scalable and distributed back-ends for collaborative software systems at Apple and Infoseek. He holds a bachelor's degree in computer science from Dartmouth College.

Services in the Long Tail World:

ABSTRACT
This talk will focus on Internet based systems that are primarily participatory in nature. In such systems, we need to think beyond infrastructure, data,and algorithms. While these entities are well-understood from the service architecture point of view, the demands of participatory systems are different. In a massive-scale system like eBay, that's highly participatory in nature, user roles, actions and interactions affect and influence how the system functions and scales. While applications and platforms as service are well understood in the current evolution through participation mandates the need for additional service orientations. For example, Interface as a service through programmable implementations or User Experience as a service through programmable visual elements and interactions can be easily perceived. Machines and machine algorithms will take us part of the way but making them scalable and adaptable to change is a challenge. We need to talk about augmented intelligence where machine power coexists with and is complemented by human intelligence. Designing scalable services and applications in this dynamic context pose interesting challenges and new opportunities. This talk will focus on the unique nature of this Long tail world.

ABSTRACT
SOA and Web services have profoundly changed enterprise and commercial applications. BPEL, dynamic binding via service registries and repositories, alignment of grid computing with Web service standards, and a common approach to SOA and event driven architectures are examples of technologies that enable a new approach to applications and solutions. Many papers and talks have explained these technologies and their benefits.
Systems and application management using Web services is a growing area that builds on these technologies. There are many benefits to a common SOA/Web service approach to modeling, developing, deploying, managing and optimizing SW solutions. This presentation explains the benefits.
Several significant intellectual challenges hinder realizing the promise of a SOA/Web service approach to systems and application management. One of the most important is "managing from a business service perspective." Business professionals have a completely different definition of "service" from technical professionals. Enterprises think in terms of IT realization of "business services," for example online banking or shipped package tracking. The business services are an interacting fabric of SOA services, and in many cases the enterprise does not fully understand which services interact in a business solution or to process a request. Many elements in the business service are not SOA services, for example databases, directories, file servers, etc.
This talk provides a deeper explanation of the business problem and challenges. The talk also explains the state of the art for solving some of the challenges. Finally, the talk concludes with suggestions for research and projects.
