The use of this technology has allowed minor projects to allocate proper computational resources to their demands, with lower budgets. On the other hand many conventional users keep ignoring the Cloud potentialfast deployment, payper-use, elasticity, adaptability, among others. Our objective was to prove the feaseability of scientific applications and delineate an outline work that researchers could follow to take advantage of the Cloud infrastructure. This work describes the migration of a weather forecast application to the Cloud, demonstrating a system contextualization, application analysis, virtualization and deployment. We compare performance and combined costs of the several types of Clouds with the original solution and also future solutions.

High-performance Computing, a complex problem solving class, arises as a new business consumer by taking advantage of the Cloud premises and leaving the expensive datacenter management and difficult grid development. Standing on an advanced maturing phase, today’s Cloud discarded many of its drawbacks, becoming more and more efficient and widespread. Performance enhancements, prices drops due to massification and customizable services on demand triggered an emphasized attention from other markets. HPC, regardless of being a very well established field, traditionally has a narrow frontier concerning its deployment and runs on dedicated datacenters or large grid computing. The problem with common placement is mainly the initial cost and the inability to fully use resources which not all research labs can afford.

Still, it lacks a sustaining basis such as standard methods and deployment settings to potentiate a full evolution. Interoperability and interchangeability are expected to overcome vendor lock-ins. This paper overviews the problem with a state-of-the-art review and reflects some of the undergoing approaches.

Knowing the importance of this tool, the University of Aveiro (UA) developed in the last years its institutional portal. In this paper, we look for describing the diverse steps in the implementation of this application, since the necessary survey of requirements, followed by i) the necessity of development and integration of information subsystems; ii) the development of an institutional image and identity, and iii) the involvement of the university community at the final stage of the process. We also aim to describe the diverse phases of the Portal implementation until its launching.

Yet, the Cloud wide spawn has opened a new window of development by combining groups of Clouds: Sky Computing. The Clouds in the Sky essentially blend efforts. How to manage these Clouds and to deploy applications becomes an upcoming challenge. A good example is the use of High Performance Computing on the Cloud, which would significantly drop costs and would encourage low budget projects.

Despite the benefits of such an approach, this service model usually comes with a high level of the lock in effect into the service provider. The lock in effect occurs when a software developer needs to change its cloud provider. When this happens, it usually means a major application rewrite, specific for the new PaaS. This paper details the initial results of a project whose goal is to build a PaaS where vendor lock in does not occur. With this PaaS, developers wishing to deploy their applications into the cloud may continue to program using their usual development environments. There are no necessary changes required to make the application PaaS compatible. As a proof of concept, we developed an open source PaaS management application as a regular web application and then deployed it on the cloud.
