Cloud Computing is shaping the way that organizations acquire and use systems -- software-as-a-service (SaaS) model -- and how they develop and deploy systems -- platform-as-a-service (PaaS) and infrastructure-as-a-service (IaaS) models. This emerging computing paradigm is having a significant impact on the way modern software is designed, developed, deployed and governed. Even though cloud platforms and infrastructures are typically designed to scale on demand, the question is whether this automatic elasticity translates to all services deployed on them. Other qualities of concern and interest in this environment include monitorability, manageability, privacy, security, availability and reliability. Software-intensive services in the cloud will have to be better engineered, to either take advantage of the qualities offered by cloud platforms and infrastructures or to account for lack of full control over important quality attributes. There are therefore a number of open software engineering research challenges related to design, development, deployment, use, and integration of software and cloud services.

Topics

This year's PESOS forum seeks contributions addressing, but not limited to, the following topics related to software engineering for services in the cloud:

Service engineering for elasticity, scalability, monitorability, and other attributes expected of cloud services
Methods and tools for design-time software engineering support for desired run-time behavior in the cloud
Management and governance of service-oriented systems in the cloud
Requirement engineering issues for cloud services
Adaptation and evolution of service-oriented systems
Service personalization and context-aware provisioning in the cloud
Service dependability, survivability, reliability and resilience
Trust, security, and privacy in service-oriented systems
Quality of service (QoS) and Service-level Agreements (SLAs)
Management of non-functional requirements for cloud services
Verification and validation of service-oriented systems
System migration to service-oriented systems in the cloud
Service delivery models for mobile users and mobile applications.
Service-oriented systems supporting cloud-based provisioning.
Case studies and industry experiences.
Cloud requirements and design for growing markets.

In addition, PESOS 2014 will continue "The Quest for Case Studies." Started at PESOS 2012 as a special session, we are now making it an essential part of the workshop as the forum for researchers and practitioners sharing this vision and willing to contribute with their effort and experience. The goal is to create the reference set of case studies for the research community in service-oriented systems, hosted on a publicly available repository: http://www.s-cube-network.eu/use-cases.
