Kurzfassung
Cloud computing is the latest computing paradigm that delivers
hardware and software resources as virtualized services
in which users are free from the burden of worrying
about the low-level system administration details. Migrating
Web applications to Cloud services and integrating
Cloud services into existing computing infrastructures
is non-trivial. It leads to new challenges that often require
innovation of paradigms and practices at all levels: technical,
cultural, legal, regulatory, and social. The key problem
in mapping Web applications to virtualized Cloud services
is selecting the best and compatible mix of software images
(e.g., Web server image) and infrastructure services to ensure
that Quality of Service (QoS) targets of an application
are achieved. The fact that, when selecting Cloud services,
engineers must consider heterogeneous sets of criteria
and complex dependencies between infrastructure services
and software images, which are impossible to resolve manually,
is a critical issue. To overcome these challenges, we
present a framework (called CloudGenius) which automates
the decision-making process based on a model and factors
specifically for Web server migration to the Cloud. Cloud-
Genius leverages a well known multi-criteria decision making
technique, called Analytic Hierarchy Process, to automate
the selection process based on a model, factors, and QoS parameters
related to an application. An example application
demonstrates the applicability of the theoretical CloudGenius
approach. Moreover, we present an implementation of
CloudGenius that has been validated through experiments.
