SLA@SOI was delighted to participate in the RealTime Webcamp held in Ljubljana on the 20th February 2010. Primož Hadalin from XLAB presented (in Slovene) how XMPP technologies have been used in our initial infrastructure monitoring implementations. For this and other presentations please see our publications page.
Over the last few years, several approaches have been developed to support the monitoring of SLAs. Typically, these approaches collect events during service executions and use them to check whether the properties of service provision as specified in an SLA are satisfied. Such approaches provide state of the art mechanisms for performing the basic checks [...]
In parallel with the industrial use-case planning and requirements gathering activities in the first phase of the project, technical partners explored some of the broad architectural and integration challenges with an adhoc demonstrator. The following video demonstrates some of the capabilities of the software they developed.
The software illustrated in this video is currently being modified [...]
Service-Oriented Architecture (SOA) represents an architectural shift for building business applications based on loosely coupled services. In a multi-layered SOA environment the exact conditions under which services are to be delivered can be formally specified by Service Level Agreements (SLAs). However, typical SLAs are just specified at the top-level and do not allow service providers [...]
We are happy to announce that more of the outputs of year one of SLA@SOI are now publicly available.
Well, Hui Li from SAP has been busy and successful on his work within SLA@SOI! Along with his co-authors they have had the following papers successfully accepted:
Hui Li, Giuliano Casale, Tariq Ellahi. SLA-Driven Planning and Optimization of Enterprise Applications. 1st joint ACM WOSP/SIPEW Intl. Conference on Performance Engineering, San Jose, CA USA, Jan 2010. With [...]
We are delighted to announce that our paper entitled “SLA-aware Resource Management” has been accepted for presentation at the SLAs in Grids workshop alongside the IEEE/ACM Grid 2009 conference in Banff, Canada. For more information check out the conference website. Congratulations to all involved!

The financial sector depends heavily on process and data intensive computations to deliver competitive advantage. Financial applications are particularly suited to grid-based experimentation and research. A Financial Live Trading System is used an exemplar in this article. The emerging growth of worldwide trading and the reliance on automated processing has increased the complexity and volatility [...]
Originally, (Web) services were deployed and used with almost no actual control by the different parties. The simplistic assumption that their behavior was correct and everyone had to be happy with the functionality provided was unrealistic. The actual exploitation of services, imposed us to start conceiving different methods and tools to manage the complete life-cycle of deployed and running services with special emphasis on the actual run-time behavior.
SLA@SOI will co-sponsor the 3rd Workshop on Non-Functional Properties and SLA Management in Service-Oriented Computing (NFPSLAM-SOC).
This event will take place from the 24th to the 26th of November 2009 in Stockholm, Sweden and is to be held in conjunction with The 7th International Conference on Service Oriented Computing (ICSOC2009).
This workshop aims to tackle the research [...]
