International Workshop on Hot Topics in Cloud service Scalability (HotTopiCS 2014)
22 March 2014 Dublin (co-located with ICPE2014)
http://icpe2014.ipd.kit.edu/conference_workshops/hottopics2014/

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.

Topics
------

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

Submission
----------

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.
