Performance of Grids and Clouds

Mañana 18 de septiembre tendrá lugar la conferencia ‘Performance of Grids and Clouds- State-of-the-Art and Future Research Directions’ por parte de Helen D. Karatza a las 12:00 horas en el Salón de Grados de la Escuela Técnica Superior de Ingeniería Informática (ubicada en la avenida Reina Mercedes, Sevilla).

The popularity of grids and clouds has been growing rapidly, and their performance becomes more important due to the tremendous increase of users and applications.

Because of the nature of these systems, there are important issues that must be addressed, such as: resource allocation, efficient scheduling, energy conservation, reliability, security and trust, cost, availability, quality. Effective management of grid and cloud resources is crucial to use effectively the power of these systems and achieve high system performance. Furthermore, due to the cost of electrical power consumption and the environmental impact, energy efficiency in grid and cloud systems is a global IT concern.

Cloud computing is a concept that has emerged from grid computing; it provides users the ability to acquire computational resources on demand from its virtually infinite pool on a pay-as-you-go basis.

The cloud computing paradigm can offer various types of services, such as computational resources for HPC applications, web services, social networking, etc. Resource allocation and scheduling is a difficult task in clouds where there are many alternative heterogeneous computers. If cloud computing is going to be used for HPC, appropriate methods must be considered for allocating resources to user requests efficiently, VM scalability, as well as effectively scheduling the tasks. The scheduling algorithms must seek a way to maintain a good response time to leasing cost ratio. Furthermore, adequate data security and availability are critical issues that have to be considered along with energy-efficient solutions that are required to minimize the impact of cloud computing on the environment.

In this talk I plan to present state-of-the-art research covering a variety of concepts on grid and cloud computing, and to provide future trends and directions in the cloud computing area.
