Many small and medium size research groups have limitations to execute their HPC workloads because of the need to buy, configure and maintain their own cluster or grid solutions. At the same time, some research groups have large infrastructures with low utilization levels due in part to the tools they offer to end users, that require that each end user configures complex and distributed environments...
Large Internet companies like Amazon, Netflix, and LinkedIn are using the microservice architecture pattern to deploy large applications in the cloud as a set of small services that can be developed, tested, deployed, scaled, operated and upgraded independently. However, aside from gaining agility, independent development, and scalability, infrastructure costs are a major concern for companies adopting...
Hundreds of companies trying to move their JEE applications to the cloud face different challenges because these applications were developed without considering their deployment in cloud infrastructures. This fact typically generates that those companies have to pay large infrastructure costs in their cloud deployments. In the short-term, those companies have to decide if they should continue paying...
Cloud computing provides new opportunities to deploy scalable application in an efficient way, allowing enterprise applications to dynamically adjust their computing resources on demand. In this paper we analyze and test the microservice architecture pattern, used during the last years by large Internet companies like Amazon, Netflix and LinkedIn to deploy large applications in the cloud as a set...
This poster shows the performance evaluation of UnaCloud Opportunistic Computing IaaS. We analyze from an HPC perspective, two virtualization frameworks Virtual Box and VMware ESXi and compare them over this particular opportunistic cloud environment. The benchmarks consist of two set of tests, High Performance Linpack and IOzone, that examine the performance and the Input/Output response. The purpose...
UnaCloud is an opportunistic based cloud infrastructure (IaaS) that allows to access on-demand computing capabilities using commodity desktops. Although UnaCloud maximizes the use of idle resources to deploy virtual machines, it does not use energy-efficient resource allocation algorithms. In this paper, we design and develop different energy-aware algorithms to operate in an energy-efficient way...
Cloud computing promises to offer great opportunities for research groups, however when researchers want to execute applications in cloud infrastructures many complex processes must be accomplished. In this paper we present the e-Clouds project which will allow researchers to easily execute many applications on public Infrastructure as a Service (IaaS) solutions. Designed for being a Software as a...
This paper analyzes in detail the difficulties and issues that must be faced when running MPI (Message Passing Interface) applications over non-dedicated infrastructures. Alternatives to overcome these issues on a specific opportunistic infrastructure, called UnaCloud, are presented. We designed and implemented a UnaCloud extension to allow automatic recovery of the execution of MPI applications....

This paper presents a concept for an e-Science oriented opportunistic cloud computing service, as an infrastructure to offer to researchers computing resources with the flexibility and ease of use of a cloud computing service, supported through the opportunistic use of the idle computing resources available in academic institutions. Also we present the work done in the context of the UnaCloud project,...
This paper deals with the design and implementation of a virtual opportunistic grid infrastructure that allows taking advantage of the idle processing capabilities currently available in the computer labs of a university campus, ensuring local users to have priority in accessing the computational resources, while simultaneously, a virtual cluster takes the resources unused by them. A virtualization...
