This page provides information about the 'EGI Applications on Demand' infrastructure, hereafter referred to as the Infrastructure.
The EGI Applications on Demand service (also called AoDs) is the EGI’s response to the requirements of researchers, scattered across Europe, without dedicated access to computational and storage resources, as well as other facilities needeed to run scientific applications.
The new service, through a lightweight user registration process, offers authorised users a grant, with a pre-defined quota of resources, which can be used to run a growing number of scientific applications from a portfolio. The grant to run scientific applications can be renewed or increased upon request. The portfolio of scientific applications is currently composed by a pre-defined set of applications from different scientific areas. This portfolio can be further extended thanks to the contributions of users of the service.
Overview
The EGI Applications on Demand service architecture is presented in Figure 1.
This architecture is composed by the following components:
- The User Registration Portal (URP) is a web portal which is used to authenticate users interested to access the Infrastructure. For the authentication, the portal relies on the EGI AAI CheckIn service which provides AAI services for both users and service providers. The EGI AAI CheckIn service supports different IdPs, eduGain, the international inter-federation service, and social credentials (e.g. Facebook, Google). During the authentication process, users can provide information about their contact, institutions and research topic. Such information will be taken into account by the operator(s) to evaluate whether the user is entitled to access and use the resources and the scientific applications available in the Platform. This User Registration Portal (URP) is accessible at http://access.egi.eu
- A catch-all VO called ‘vo.access.egi.eu’ and a pre-allocated pool of HTC and cloud resources configured for supporting the EGI Applications on Demand research activities. This resource pool currently includes cloud resources from Italy (INFN-Catania and INFN-Bari) and Spain (BIFI, CESGA) and HTC clusters from Belgium (VUB), Italy (INFN-Catania and INFN-Bari), Poland (CYFRONET) and Spain (CESGA).
- The X.509 credentials factory service (also called eToken server)[1] is a standard-based solution developed for central management of robot certificates and the provision of Per-User Sub-Proxy (PUSP) certificates. PUSP allows to identify the individual user that operates using a common robot certificate. Permissions to request robot proxy certificates, and contact the server, are granted only to Science Gateways/portal integrated in the Platform and only when the user is authorized.
- A set of Science Gateways/portal to host scientific applications that users can run accessing the EGI Applications on Demand service. Currently the following three frameworks are used: The Catania Science Gateway (CSG), the WS-PGRADE/gUSE portal and the Elastic Cloud Computing Cluster (EC3).

Monitoring:
- The EGI Applications on Demand service components have been registered in the GOCDB [2] and connected with the EGI monitoring system based on ARGO[3]. By default ARGO automatically gathered the services endpoints from the GOCDB and implements simple https checks using standard NAGIOS probes. If necessary new ones can be easily developed and added.
To monitor the status of Platform services (e.g. GRIDOPS-CSFG, GRIDOPS-LTOS, GRIDOPS-WS-PGRADE, GRIDOPS-EC3)[3] , check the following ARGO report page.

Accounting:
- Accounting data about the VO users can be checked here: https://accounting.egi.eu/
- From the EGI Accounting Portal it is possible to check the accounting metrics generated for both grid- and cloud-based resources supporting the vo.access.egi.eu VO. From the top-menu click on 'Restrict View' and 'VO Admin' to check the accounting data of platform users.
