Cloud computing promises a radical new way in design of the IT systems. Due to advances in virtualization technology in the last decade this paradigm has gained a lot of traction among the IT managers, offering a new perspective in design and development of the next generation software and hardware applications. One of the most appealing characteristics of cloud computing is the pay-as-you-go model which allows customers to start with a small IT investment and grow as required, minimizing risks. For cloud providers, in order to be able to sustain this business model it is important to be able to gather and process usage metrics of the resources provided in order to generate accurate invoices for customers. This paper presents the metrics collections used with each cloud offering (IaaS, PaaS and SaaS) and proposes a novel architecture for collecting these metrics using a Multi Agent System platform, together with a Web J2EE application for real time data visualization and reporting. The solution is built and presented in the context of IBM CloudBurst 2.1, managed by IBM Tivoli Service Automation Manager (TSAM) software stack, while virtualization is provided by VMware ESX 4.0 hypervisor with VMware vCenter solution. |
