D.A4a SLA-Aware Infrastructure Management
The SLA@SOI project is committed to research, engineer and demonstrate technologies that can embed SLA-aware infrastructures into the service economy. These technologies span the business, service and infrastructure layers a service economy depends upon. In SLA@SOI the Infrastructure Management work package is responsible for the infrastructure layer.
This document details the progress made in the Infrastructure Management work package in SLA@SOI over the first 12 months of the project.
Achievements include the completion of a comprehensive state-of-the-art review, together with the gathering of requirements, both implicit and explicit. A flexible, scalable architecture for Infrastructure Management has been defined, and a reference implementation created for demonstration purposes. An internet-accessible testbed has been deployed, and is used to host various components of the prototype. Software development best-practices have been promoted, and proliferated across the project.
Technical highlights including defining flexible external and internal models, documenting a harmonized interface, realising a distributed agent-based architecture, implementing a highly scalable XMPP-based messaging layer and realising powerful, distributed monitoring. Already this work is beginning to influence external standards initiatives: feedback from Infrastructure Management blog posts have ultimately leaded to the receipt of an invitation to co-chair the newly-formed OVF working group Open Cloud Computing Interface (OCCI).
With SLAs at its core, SLA@SOI Infrastructure Management has a focus unique to the industry. As the cloud computing movement matures, this work package will strengthen its engagement with the community, promoting SLA-aware service oriented infrastructures, helping to realise the vision of the project.
