- Service name: Message brokers
The message broker network is a fundamental part of the operations infrastructure ensuring message exchange for monitoring, the operations dashboard and accounting. As such it is a critical core infrastructure platform service component whose continuity and high availability configuration must be ensured.
Given the critical nature of the activity bid must contain an availability and continuity plan for the service.
The EGI Production Messaging Infrastructure serves as a backend infrastructure for EGI operational tools that need to use a brokering functionality for message communications purposes (i.e. SAM infrastructure, APEL, the Operations Portal). The service component to be provided needs to provide scalability and redundancy with its topology in order to keep up with the message load produced by the operations tools . The scalability of the service should be adjusted to support the amount of monitoring and accounting data produced by the sites that are part of the EGI Federation of High Throughput Computing, storage and cloud services. Currently the number of services is about 5,000 and the number of resource centres is about 300.
This activity is responsible for
- the coordination of the system operations and upgrade activities with those partners that are in charge of operating other systems that depend on it to ensure continuity of the service.
- requirements gathering.
- Daily running of the system in high availability configuration
- Maintenance of probes to test the functionality of the service
Support of message production, exchange and consumption process through the EGI helpdesk.
Support is provided to the operators of systems that rely on the EGI Message Broker Network capability.
Support hours: eight hours a day (for example 9-17 CE(S)T), Monday to Friday – excluding public holidays of the hosting organization.
- Bug fixing and proactive maintenance of the software
- Changes in the system must be rolled in production in a controlled way in order to avoid service desruption.
Currently the messaging brokers network is based on ActiveMQ brokers, in the EGI-Engage project a new HTTP based messaging solution has being developed. If the transition to the new system will not happen during 2017, the activity will deploy the current system to transition to the new software during 2018.
Service level targets
The deployment of the services must ensure:
- Minimum availability/reliability: 99%/99%
- Response to incident records in GGUS within support hours: Medium (see Description page)
Bids planning a effort of 4 Person Months/year would allow these services and activities to be addressed appropriately.
