Motivation Service-oriented systems represent a new class of

software system Software is used and integrated as external, loosely-

coupled services rather than being physically integrated and owned permanently

However, service orientation poses challenges to more traditional approaches to software development Lack of homogeneity of its basic components Changing business and deployment environments

PESOS 2011

Workshop Goals Provide a forum for presenting and discussing possibilities of

synergy between Software Engineering (SE) technologies and Service-Oriented Computing (SOC) that are beneficial to both fields

Bring together researchers and practitioners working in the area of engineering service-oriented systems to discuss Research challenges Recent developments Novel applications Methods, techniques and tools Theoretical foundations Empirical studies Experiences Lessons learned

Workshop History

SDSOA 2007

• Organizers from Software Engineering Institute, IBM Canada,

European Software Institute and the

University of Waterloo• presentation of results

from a SOA Research Agenda IRAD project

SDSOA 2008

• Research agenda was used as the

framework for the workshop

• Updates were presented

PESOS 2009

PESOS 2009

• Organized by a group of EU researchers

• Focus on how to achieve evolution and adaptation in a secure and dependable way

Invited presentation of the

SOA research agenda showed

huge potential for synergy between both communities

Successful joint

proposal

PESOS 2010

IW-SOSE 2006 IW-SOSE 2007

Focus on the engineering of service-oriented software systems

Focus on the engineering and use of

service-oriented software systems

Here we are again!
