International Workshop on Hot Topics in Cloud Services (HotTopiCS 2013)

April 20–21, 2013

Registration is now available here. Advance registration deadline is March 15, 2013. Tentative program is available. The program now also contains slides of the presentations.

Cloud computing as a novel paradigm for providing data centre resources (computing, network and storage) as on demand services promises significant cost savings by making it possible to consolidate workloads and share infrastructure resources among multiple applications resulting in higher cost- and energy-efficiency. The Cloud seems particularly well-suited for the service-oriented paradigm of software development, which already hides a lot of implementation detail behind a service’s interface. Similarly, the Cloud hides details of data centre management and maintenance such as resource management, location and allocation, or pricing strategies behind a public interface.

While there has been substantial research in the field already, there still remain open challenges—for example in the areas of resource management for elasticity, automated pricing strategies, or VM and service migration.

Hot Topics in Cloud Services provides a platform for academics and industrial practitioners to exchange novel research ideas and current problems from practice and to identify new and "hot" topics in the field. As indicated by the co-location with ICPE, we are particularly interested in work tackling performance-related problems (understood in a very broad sense), but other work related to the creation and management of service-based cloud applications (e.g., from an economic perspective) are equally welcome.

Topics of Interest

Topics of interest include (but are not limited to) the following areas:

  • Resource management in the Cloud for elasticity and/or cost-minimisation
  • Virtualization platforms and management of virtual appliances
  • Cloud storage architectures
  • Network virtualization approaches for cloud computing
  • Autonomic/self-managed cloud architectures
  • Quality-of-service management including performance, reliability, availability, resilience, security and privacy aspects
  • Power and energy efficiency
  • Service-level agreement definition and enforcement
  • Design-time analysis and prediction of non-functional properties of service-based Cloud applications
  • Design and implementation of service-based Cloud applications
  • Design of scalable cloud applications
  • Provision and design of IaaS, PaaS, and SaaS systems
  • Cloud programming models and interoperability
  • Transition from traditional data centre hosting into cloud-services
  • Migrating traditional on-premise applications to the cloud
  • Hybrid models (private & public cloud)
  • Economic models of the Cloud and related pricing schemes and business models
  • Technical & non-technical constraints (e.g., legal, privacy, security)
  • Monitoring, reporting, and failure recovery
  • Multi-tenant architectures and related aspects such as performance isolation
  • Mobile clouds
  • Big data applications
  • Novel cloud applications and case studies
  • Methods and metrics for quantitative evaluation of Cloud systems with respect to performance, elasticity, isolation, scalability, dependability (availability, reliability and resilience), power consumption and energy efficiency.
  • Benchmarking methodologies
  • Workload characterization and reproducibility

Submission Format, Publication

Authors are invited to submit original, unpublished papers that are not being considered in another forum. Duplicate submissions will be rejected without review. At least one author of each accepted paper is required to attend the workshop and present the paper. Only the accepted and presented papers will be included in the Workshop Proceedings which will be published by ACM in the ACM Digital Library.

Papers should be up to 8 pages in the standard ACM format for conference proceedings and must be written in English. We explicitly invite work-in-progress papers as well as position or vision papers. Papers can be submitted through EasyChair until the deadline.


Alexandru Iosup (TU Delft) will be giving a keynote talk at HotTopiCS. More details will be posted here soon.
