Introduction

This page reports on the Availability and Continuity Plan for the EOSC Portal and it is the result of the risks assessment conducted for this service: a series of risks and treats has been identified and analysed, along with the correspondent countermeasures currently in place. Whenever a countermeasure is not considered satisfactory for either avoiding or reducing the likelihood of the occurrence of a risk, or its impact, it is agreed with the service provider a new treatment for improving the availability and continuity of the service. The process is concluded with an availability and continuity test.

Risks analysis

Risk id Risk description Affected components Established measures Risk level Expected duration of downtime / time for recovery Comment
1 Service unavailable / loss of data due to hardware failure EOSC Portal user GUI, EOSC Portal database All services are running on virtual machines. In case of hardware failure of the host machine the virtual machine can be re-instantiated.
2 Service unavailable / loss of data due to CEPH file system in the cloud infrastructure EOSC Portal user GUI, EOSC Portal database All services databases are backed up on a tape storage. Service VM will be restored with the database back up from the tape storage.
3 Service unavailable / loss of data due to software failure EOSC Portal user GUI, EOSC Portal database Monitoring of system health, backups
4 service unavailable / loss of data due to human error EOSC POrtal user GUI Monitoring of system health, backups
5 service unavailable for network failure (Network outage with causes external of the site) Monitoring of service availability, ACC Cyfronet AGH has redundant network connectivity.
6 Unavailability of key technical and support staff (holidays period, sickness, ...) EOSC Portal user GUI, EOSC Portal database More personnel may be involved in the operation of the EOSC Portal
7 Major disruption in the data centre. Fire, flood or electric failure for example EOSC Portal user GUI, EOSC Portal database The computing centre has electric backup system and fire control devices.
8 Major security incident. The system is compromised by external attackers and needs to be reinstalled and restored. EOSC POrtal user GUI Monitoring of system health, security audits, backups, following best practices for security configuration and timely implementation of patches
9 (D)DOS attack. The service is unavailable because of a coordinated DDOS. Local network team provides monitoring and protection for DOS attacks, firewall can limit impact of the DDoS

Outcome

Additional information

procedures for the several countermeasures to invoke in case of risk occurrence (put a link if public)

Specify if the Availability targets are different in case the plan is invoked.

Specify the recovery requirements (in general they are the outcomes of the BIA).

Specify if there is a particular approach for the return to normal working conditions if different from what already reported in the risk assessment.

The support unit ... shall be used to report any incident or service request

The providers can contact EGI Operations via ticket or email in case the continuity plan is invoked, or to discuss any change to it.

Availability and Continuity test

The proposed A/C test will focus on a recovery scenario: the service is supposed to have been disrupted and needs to be reinstalled from scratch. Typically this covers the risks #,#, and #. The last backup of the data will be used for restoring the service, verifying how much information will be lost, and the time spent will be measured.

Performing this test will be useful to spot any issue in the recovery procedures of the service.
