Paper Title
Mapping Multi-Tier Architecture Into Cloud Environment Using Slicing And Virtualization
Abstract
There exists a huge amount of vertical applications that are developed for isolated computing environments. Due
to increasing demand for additional resources there is a clear need to adapt these applications to the distributed
environments. However, this is not an easy task and numerous variants are possible. Moreover, in this transition a new
quality requirements become important, such as application elasticity. Application elasticity has to be built into a software
system to enable smooth cost optimization at the run-time.
In this, we provide a framework for evaluating different transformation variants of vertical Java EE multi-tiered applications
into elastic cloud applications. With support of this framework the software developer is guided how to transform its
application achieving optimal elasticity strategy. The framework is evaluated on slicing and evaluating elasticity of existing
SaaS multi-tiered Java application used in Croatian market.
Keywords— Multi-tier Architecture, Cloud Migration.
