In the last couple of years, cloud computing records a
rapidly increasing popularity due to scalable, elastic
infrastructures that are charged according to their usage and do
not have to be maintained. However, the offerings of cloud
providers sometimes drastically differ and therefore, it gets more
and more difficult for users to compare clouds and choose a
proper provider for a specific service. Furthermore, the demand
of changing the provider and migrating existing services results
from the growing market. The main problems and obstacles that
follow the migration of services from the technical point of view
are: First, cloud providers are using own platforms or APIs so
services have to be adapted to them; and second, services cannot
be migrated without an interruption. Besides the technical
aspects, there are also economical ones. Companies have to spend
a lot of time comparing different offerings and adapt their
applications. This paper proposes the dynamic Platform as a
Service (dynPaaS), a new form of Platform as a Service provider
that addresses these issues. The dynPaaS framework abstracts
existing clouds, finds the optimal cloud for a service according to
its requirements and provides transparency about the underlying
clouds. It monitors clouds and hosted services, dynamically
migrates services between clouds on the basis of changing
parameters, and optimizes the resource usage of integrated
clouds. The result is a price reduction for both, the cloud users
and the dynPaaS provider.
