Status and evolution after April 2014
Operation Management Board Coordination
The Operations Management Board (OMB) drives future developments in the operations area by making sure that the infrastructure delivers high availability, is secure, meets the demand of existing user communities and that infrastructure operations evolve to support the integration of new resource infrastructures. It does this by providing management and developing policies and procedures for the operational services that are integrated into the production infrastructure.
EGI.eu provides first and second level user and operations support and this function includes the following tasks:
- function coordination (partner: CESNET)
- ticket triage and assignment for dispatching of tickets to the appropriate SUs within GGUS (partners: INFN, CESNET)
- 1st and 2nd level software support, encompassing both grid middleware and operational tools (operational tickets are dispatched to NGI operations SUs, so are not internally addressed by the software support team). This includes the production of howtos and reporting to operations meetings about critical incidents (partners: CESNET, INFN, JUELICH, LIU and STFC
- Ticket oversight and follow-up (partner: KIT): this function includes administrative and reporting functions of the helpdesk infrastructure (e.g. collecting ticket statistics, internal and external reporting of statistics for SLAs monitoring and other reporting duties), and follow-up (notifying supporters when the reaction to high-priority tickets is not fast enough, requesting information from ticket submitters when they do not react, ensuring assigners/resolvers will react sufficiently fast when the submitter provides additional information).
Coordination of Grid Oversight
Partners: SARA, CYFRONET
Grid Oversight is an activity aimed at controlling the infrastructure and solving arising operational issues. Theses issues can be of different complexity and importance, and may be caused by various reasons on regional or central level. For the scalability reasons the Grid Oversight has hierarchical structure: teams on regional (ROD) and central (COD) level contribute to it, solving problems within their scope. The COD part of the function is a global task. Speaking in ITSM terms the processes in which COD is naturally interested in are these of Service Operations area, especially Incident Management and Problem Management. The oversight of Incident Management is organized in an escalation process and COD is the body to which incidents that can not be handled on regional level are escalated.
Coordination of network support, monitoring, troubleshooting
Provides network support for the resolution of end-to-end network performance issues. EGI is a highly distributed networked infrastructure of grid services using network connectivity for remote job submission, data transfer and data access, hence tools are needed for network troubleshooting and performance monitoring
Coordination of Operational interoperation between NGIs and DCIs
EGI coordinates the integration of heterogeneous middleware stacks and Distributed Computing Infrastructures with the EGI operational infrastructures such as: accounting, monitoring, managemenet and support.
Coordination of documentation
Coordination of maintenance and development operational documentation, procedures, best practices.
This activity is part of the OMB duties. Partner: EGI.eu ( Fill assessment)
Security vulnerabilities and risks presented by e-Infrastructures provide a rationale for coordination amongst the EGI participants at various levels. Central coordination groups ensure policies, operational security, and maintenance to guarantee secure access to users. In addition, security and incident response is provided through the EGI Computer Security and Incident Response Team by coordinating activity at the sites across the infrastructure. This coordination ensures that common policies are followed by providing services such as security monitoring, training and dissemination with the goal of improving the response to incidents (e.g. security drills).

This task includes the validation of distribution of monthly availability statistics, and the coordination of the evolution of the EGI OLA framework.

Updates of deployed software need to be gradually adopted in production after internal verification. This process is implemented in EGI through staged rollout, i.e. through the early deployment of a new component by a selected list of candidate Resource Centres. The successful verification of a new component is a precondition for declaring the software ready for deployment. Given the scale of the EGI infrastructure, this process requires careful coordination to ensure that every new capability is verified by a representative pool of candidate sites, to supervise the responsiveness of the candidate sites and ensure that the staged rollout progresses well without introducing unnecessary delays, and to review the reports produced. It also ensures the planning of resources according to the foreseen release schedules from the Technology Providers. EGI.eu coordination is necessary to ensure a successful interoperation of the various stakeholders: Resource Centres, Technology Providers, the EGI.eu Technical Manager and the EGI repository managers.
This activities includes:
- Definition and adoption of a workflow to automate software deployment
- Coordination of the staged rollout activities carried out by the NGIs
- Liaison with the UMD team (EGI-InSPIRE SA2)

Description: A distributed monitoring framework is necessary to continuously test the level of functionality delivered by each service node instance in the production Resource Centres, to generate alarms and tickets in case of critical failures and to compute monthly availability and reliability statistics, and to monitor and troubleshoot network problems. The Monitoring Infrastructure is a distributed service based on Nagios and messaging. The central services – operated by EGI.eu – include systems such as the MyEGI portal for the visualisation of information, and a set of databases for the persistent storage of information about test results, availability statistics, monitoring profiles and aggregated topology information. The central services need to interact with the local monitoring infrastructures operated by the NGIs. The central monitoring services are critical and need to deliver high availability.

The EGI Accounting Infrastructure is distributed. At a central level it includes the repositories for the persistent storage of usage records, and a portal for the visualisation of accounting information. The central databases are populated through individual usage records published by the Resource Centres, or through the publication of summarised usage records. The Accounting Infrastructure is essential in a service-oriented business model to record usage information. Accounting data needs to be validated and regularly published centrally.

The objective of a Security Infrastructure is to protect itself from intrusions such as exploitable software vulnerabilities, misuse by authorised users, resource "theft", etc., while allowing the information, resources and services to remain accessible and productive to its intended users. A specifically designed set of tools and services help reduce these vulnerabilities such as monitoring individual resource centers (based on Nagios and Pakiti), a central security dashboard to allow sites, NGIs and EGI Computer Security Incident Response Teams to access security alerts in a controlled manner, and a ticketing system to support coordination efforts.

Configuration Repository (GOCDB)
EGI relies on a central database (GOCDB) to record static information about different entities such as the Operations Centres, the Resource Centres, and the service instances. It also provides contact, role and status information. GOCDB is a source of information for many other operational tools, such as the broadcast tool, the Aggregated Topology Provider, etc.
Partner: STFC ( Fill assessment)
EGI.eu provides a central portal for the operations community that offers a bundle of different capabilities, such as the broadcast tool, VO management facilities, and a dashboard for grid operators that is used to display information about failing monitoring probes and to open tickets to the Resource Centres affected. The dashboard also supports the central grid oversight activities. It is fully interfaced with the EGI Helpdesk and the monitoring system through the message passing. It is a critical component as it is used by all EGI Operations Centres to provide support to the respective Resource Centres.

EGI provides support to users and operators through a distributed helpdesk with central coordination (GGUS). The central helpdesk provides a single interface for support. The central system is interfaced to a variety of other ticketing systems at the NGI level in order to allow a bi-directional exchange of tickets (for example, those opened locally can be passed to the central instance or other areas, while user and operational problem tickets can be open centrally and subsequently routed to the NGI local support infrastructures).

Auxiliary core services are needed for the good running of Infrastructure Services. Examples of such services are VOMS service and VO membership management for infrastructural VOs (DTEAM, OPS), the provisioning of middleware services needed by the monitoring infrastructure (e.g. top-BDII and WMS), the catch-all CA and other catch-all core services to support small user communities (central catalogues, workflow schedulers, authentication services).
