OGF-Europe Tutorial: How to make sustainable a grid-enabled e-Infrastructure
(90 mins)
Pasquale Pagano
The management of any grid-enabled e-Infrastructure is costly in terms of ownership, maintenance, and upgrade. e-Infrastructures must be based on advanced technology that can reduce these costs. The main focus of the tutorial is to present the benefits introduced by the gCube technology with respect to e-Infrastructure deployment costs, operational timeframes, and manpower requirements. The compliancy to standards enabling such advanced infrastructure operational procedures is also discussed. gCube leverages current grid e-Infrastructures by eliminating manual deployment overheads, allowing remote site management, and providing powerful mobile monitoring tools.
Key goals: Give an overall picture of the technologies that relying on OGF standards to leverage the operation of grid-enabled e-Infrastructures to a ready to use technology.
Target Audience: Decision makers, site managers,
Expected outcomes: Awareness about issues related with autonomic grid service deployment in distributed e-Infrastructure and how the adoption of standards contributes to their solution.
Abstract:
By definition, an e-Infrastructure is a framework enabling secure, cost-effective and on-demand resource sharing across organization boundaries. A resource is here intended as a generic entity, physical (storage and computing resources) or digital (software, processes, data), that can be shared and interact with other resources to synergistically provide some functions serving its clients, either human or inanimate. Thus, an e-Infrastructure poses as a ``broker'' in a market of resources having the role to accommodate the needs of resource providers and consumers. The infrastructure layer gives support to: {i} resource providers, in ``selling'' their resources through it; {ii} resource consumers, in ``buying'' and orchestrating such resources to build their applications. Further, it provides
organizations with logistic and technical aids for application building, maintenance, and monitoring.
A well-known instance of such an e-Infrastructure is represented by the Grid where a service-based paradigm is adopted to share and reuse low-level physical resources. Application-specific e-Infrastructures are in their turn inspired by the generic e-Infrastructure framework and bring this vision into specific application domains by enriching the infrastructural resource model with specific service resources, i.e. software units that deliver functionality or content by exploiting available physical resources.
This potentially not-limited market of resources allows a new development paradigm based on the notion of Virtual Research Environment (VRE), a.k.a. Collaboratory. This is built by aggregating the needed constituents after hiring them through the e-Infrastructure. In this development paradigm, VREs are considered as organized views built atop the pool of available assets, ranging from computers and servers to collections and services, and the VRE Management enabling technology is the one that takes care of the definition and operation of such views. To make this novel paradigm working three fundamental facilities are needed: {i} a mechanism operating the e-Infrastructure while guaranteeing all the involved parties about the Quality of Service; {ii} a mechanism supporting VO communities in easily characterizing the VRE they are interested in; {iii} a mechanism guaranteeing the deployment and operation of the
defined VREs, in addition to a comprehensive pool of resources.
This tutorial intends to present the gCube approach to the above needs. An overviews of benefits in terms of costs of deployment, timeframes and manpower requirements, and other useful information for organizations wishing to leverage grids is the main focus of the tutorial. gCube eliminates manual deployment overheads, guarantees optimal placement of services within the infrastructure and opens unique opportunities for outsourcing state-of-the-art implementations to grid-enabled e-Infrastructure.
