Anthony Keenan, Alan Stewart, Ronald Perrott Workshop On Science - PowerPoint PPT Presentation

Terence Harmer, Yih Leong Sun , Peter Wright, Anthony Keenan, Alan Stewart, Ronald Perrott Workshop On Science Applications And Infrastructure In Clouds And Grids Oxford, UK, March 15-16, 2012

 Significant growth in number of Cloud IaaS providers  Different providers, different API, different resource offering types, different pricing structures...  Complex resource choices (hardware spec, os, hosting cost, bandwidth cost, data throughput, value-added services, etc…)

How to find the most appropriate set of available resources to execute an application? Application User

 OpenNebula , Eucalyptus, Nimbus…?  Reservoir, SLASOI, Mosaic…? two infrastructure sites, separated as far as possible (site resilience), with minimal network latency, within the EU region. User Requirements

An advanced high-level programming model for building Cloud-oriented application in a multi-provider environment

 A provider-agnostic API approach  A constraints-based resource discovery approach

T. Harmer, P. Wright, C. Cunningham, and R. Perrott: Provider-Independent Use of the Cloud, in Proceedings of the 15 th International Euro-Par Conference on Parallel Processing, ser. Euro- Par ’09.

Constraints optimisation

• Security  Hardware  Software • Performance  Storage • Cost  Data • Compliance  … • … application-centric

 High Performance Computing Application ◦ Block Matrix Multiplication (linear algebra applications)

 m1.large (large instance) ◦ 2 cpu virtual cores ◦ $0.32  c1.xlarge (high cpu extra large) ◦ 8 cpu virtual cores ◦ $0.66

4 x m1.large = 1 c1.xlarge

4 x m1.large = 1 c1.xlarge 4 x $0.32 > 1 x $0.66 ($1.28) ($0.66)
