Cloud computing promises unlimited, cost-effective and agile computing resources for users. However, this new computing paradigm also poses a unique set of challenges to both cloud providers and users. On the one hand, cloud providers need to ensure that resources being provided are highly available and deliver high performance, while optimizing cloud infrastructure to reduce their operational costs. On the other hand, cloud users need to ensure that their applications receive the best performance from the cloud, while maintaining their budgetary constraints and the terms of any Service Level Agreements (SLAs) they have with their cloud providers.

Given the scale of cloud deployment, systematic analytical approaches are critically needed to provide insights to both providers and users to achieve their respective goals. For instance, cloud providers need to constantly be aware of the running status and/or anomalies in functionality from their cloud, to be able to quickly fix any issues that may arise, to adjust physical resource allocations to ensure that their customers get best performance, or plan which services to offer to get the best return on investment. Similarly, cloud users need to understand the workload to be deployed into the cloud, plan the deployment in a cost-effective way, or ascertain the flexibility and service quality provided by different cloud environments and use this to decide their deployment strategy. Analytics can play a pivotal role in all these scenarios. By gathering insights from the large amount of data from the cloud, both cloud providers and consumers can develop analytical approaches to achieving their respective objectives in spite of the scale that clouds provide.

The purpose of this workshop is to provide a forum for researchers in the related fields to exchange ideas, and share their experiences in developing analytics to better deploy, operate and use the cloud. Specifically, we seek and wish to foster research contributions that draw on statistical analysis, analytical modeling, and machine learning to develop novel solutions in this problem area.

IWCA'14 will be held in conjunction with the International Conference on Cloud Engineering (IC2E) 2014.

Workshop Program

Date: 03/11/2014

8:45-9:00am  Welcome

9:00-10am  Keynote: Lessons Learned from Hosting Scientific Research Applications in the Cloud

Dennis Gannon, Director of Cloud Research Strategy at Microsoft Research

Abstract: Microsoft Research is in its third year of making grants of Windows Azure Cloud resources to the academic community. In that period we have made nearly 200 awards. Also in that time the Azure cloud has evolved from a pure PaaS platform to include IaaS. It now hosts many new services including many of our commercial on-line products and special events such as live streaming video of the Sochi Olympics. This talk will focus on the experience and progress made by the academic researchers using Azure. The research domains for these projects include computer science, environmental and atmospheric science, life sciences and urban science. We will describe what worked well and what failed completely. Early on the projects focused on traditional scalable computing, but the more interesting current work involves machine learning and data analytics, integrating data streams and hosting services and virtual machines to support communities.
