Current Cloud’s offer is becoming day by day wider providing a vibrant technical environment, where SMEs can create innovative solutions and evolve their services. Clouds promise cheap and flexible services to end-users at a much larger scale than before. The main goal of MODAClouds is to provide a decision support system along with design and runtime environments for early prototyping and automatic deployment of applications on multi-Clouds with guaranteed QoS. Model-driven development combined with novel model-driven risk analysis and quality of service prediction enable developers to specify Cloud-provider independent models enriched with quality parameters, implement these, perform quality prediction, monitor applications at run-time and optimize them based on the feedback, thus filling the gap between design and run-time. Additionally, MODAClouds provides techniques for data mapping and synchronization among multiple Clouds. Website: http://www.modaclouds.eu/

MODAClouds provides methods, a decision support system, an open
source Integrated Development Environment (IDE) and Run-time
Environment for the high-level design, early prototyping, semi-
automatic code generation, and automatic deployment of applications on
multi-Clouds with guaranteed Quality of Service (QoS).

Cloud Challenges
• Vendor Lock-in
• Heterogeneity and lack of interoperability among different
Cloud providers
• Performance Variability:
• Cloud performance can vary at any point in time
• Unavailability problems exist even when 99.9% up-time is
advertised

Separation from provider-
specific details
• Cloud Computing:
manage your (many)
infrastructures and your
(many) platforms:
• CCIM: concepts that are
independent even from the
cloud.
• CPIM: cloud concepts that
are independent of any
cloud provider.
• CPSM: cloud provider
specific details to specify
how to run the system on a
specific cloud.
