Motivation

Software services are becoming more and more important and intertwined with our daily activities. With the growing complexity of software services and their unpredictably increasing workload, the scalability of these services becomes more and more critical. A scalable service’s implementation can sustain increasing work or load by consuming more hardware resources, as well as releasing hardware resources with decreasing work or load, all while fulfilling its SLAs.

The focus of this workshop is on service scalability: the mapping between a service’s work and load and its resulting resource consumption. Even more than performance, scalability is deeply rooted in the service’s architecture and high-level design. In this workshop, we will look at software service scalability from different angles. Scalability is relevant in conventional architectures but even more in cloud computing. Both modelling and analyses of scalability or its related properties like elasticity or efficiency as well as measurements to quantify scalability, elasticity or efficiency are relevant topics for the workshop.

Hot Topics in Cloud services Scalability 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 of software service scalability. As indicated by the co-location with ICPE, we are particularly interested in work tackling performance- or scalability-related problems (understood in a very broad sense), but other work related to the creation and management of scalable service-based cloud applications (e.g., from an economic perspective) are equally welcome.

Core topics of interest include:

  • Scalability, elasticity and efficiency concepts, definitions, metrics and modelling
  • Scalability patterns and anti-patterns
  • Software architectures for scalability
  • Design of scalable services
  • Quantifying and measuring scalability
  • Benchmarking of scalability
  • Scalability requirements engineering
  • SLAs for scalable services
  • Scalability tools
  • Scalability case studies
  • Scalability for big data
  • Scalability for cloud services

Related topics of interest include, especially if there is a clear connection to scalability, elasticity and efficiency (but are not limited to) the following areas:

  • Cloud computing, including economic modelling of them
  • Energy efficient computing
  • Multi-tenancy
  • Workload characterisation and reproducibility
  • Mobile services
  • Autonomic architectures
  • Resource management
  • Virtualisation platforms
  • Storage architectures
  • Network architectures

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.
