1. Introduction • Implementation, Chapter 6: the implemented components, as well as the necessary extensions or changes are detailed in this section from the point of view of coding and configuration. • Validation and Evaluation, Chapter 7: in this chapter we test the final prototype based on the scenario described in this document. • Outcome and Future Work, Chapter 8: we provide a conclusion of the developed work and investigate some ideas in which this diploma thesis can be extended. 6
2. Fundamentals In this chapter we give an explanation about the technologies and concepts this diploma thesis relies on. We start describing the fundamental concepts and introduce the components and prototypes that form the basis of our work. 2.1. Cloud Computing In the last decades our world has become more and more interconnected. This interconnection added to the increase of the available bandwidth and the change in business models have forced IT Systems to fulfill its demands, leading to its reorganization into a public utility which offers public services, like water, electricity, etc. The National Institute of Standards and Technology (NIST) defines Cloud computing as "a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction" [NIS11]. The Cloud computing model is composed of five characteristics: 1. On-demand self-service: a Cloud user consumes the Cloud provider’s computing capabilities automatically without the need of human interaction. 2. Broad network access: computing capabilities are available via the network and can be accessed using standard mechanisms. 3. Resource pooling: computing capabilities in the Cloud provider side are virtualized to serve multiple consumers simultaneously using a multi-tenant model. The Cloud consumer generally has no sense of the provided resources. 4. Rapid Elasticity: computing and storage resources can be dynamically (and in some cases automatically) provisioned and released to respond to the actual consumers’ demand. 5. Measured Service: resources’ usage is monitored and measured in a transparent way to the Cloud consumer and provider for control and optimization purposes. The control that the Cloud consumer has over the computer resources in a Cloud provider infrastructure is defined in three service models: Software-as-a-Service (SaaS), Platform-as-a- Service (PaaS) and Infrastructure-as-a-Service (IaaS). SaaS provides to the Cloud consumer access and usage of Cloud provider’s applications running on a Cloud infrastructure. The consumer has no control over the underlying infrastructure where the application he uses is deployed. The customer can only control individual application’s configurations during his 7
