Introduction
This page reports on the Availability and Continuity Plan for the EGI Catchall 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.

Av/Co plan | 2021-07-02 | Q3 2022 |
Previous plans are collected here: https://documents.egi.eu/secure/ShowDocument?docid=3543
Performances
In the OLA it was agreed the following performances targets, on a monthly basis:
- Availability: 95%
- Reliability 99%
Other availability requirements:
- the service is accessible through X509 certificate
- The service is accessible via CLI and/or webUI
The service availability is regularly tested by nagios probe eu.egi.VOMS-CertValidity: https://argo-mon.egi.eu/nagios/cgi-bin/status.cgi?host=voms2.hellasgrid.gr&style=detail
The performances reports in terms of Availability and Reliability are produced by ARGO on an almost real time basis and they are also periodically collected into the Documentation Database.
Over the past years, EGI Catchall hadn't particular Av/Co issues highlighted by the performances that need to be further investigated.
Risks assessment and management
For more details, please look at the google spreadsheet. We will report here a summary of the assessment.
Risks analysis
Risk id | Risk description | Affected components | Established measures | Risk level | Treatment | Expected duration of downtime / time for recovery |
---|---|---|---|---|---|---|
1 | Service unavailable / loss of data due to hardware failure | VOMS database, MyProxy proxy files | The VOMS database and the MyProxy proxy directory are regularly backuped (reactive). Additionally, they are running on a redundant VM environment, on a redundant storage (preventive) | Low | Service restored from backups | 1 working day |
2 | Service unavailable / loss of data due to software failure | VOMS database, MyProxy proxy files | The VOMS database and the MyProxy proxy directory are regularly backuped (reactive).

5 | Unavailability of key technical and support staff (holidays period, sickness, ...) | VOMS, MyProxy | There is always one member of the team available (preventive). | Low | - | - |
6 | Major disruption in the data centre. Fire, flood or electric failure for example | VOMS database, MyProxy proxy files | The data center is well maintained, with UPS, diesel generator and fire suppression system (preventive). | Medium | Service restored from backups | 1 or more working days |
7 | Major security incident. The system is compromised by external attackers and needs to be reinstalled and restored. | VOMS database, MyProxy proxy files | The VOMS database and the MyProxy proxy directory are regularly backuped (reactive). | Low | Service restored from backups | 1 working day |
8 | (D)DOS attack. The service is unavailable because of a coordinated DDOS. | VOMS, MyProxy | The network is monitored for DDOS attacks by GRNET NOC (reactive). | Medium | GRNET NOC will take proper actions | 1 working day |
Outcome
The level of all the identified risks is acceptable and the countermeasures already adopted are considered satisfactory
Additional information
- procedures for the several countermeasures to invoke in case of risk occurrence are available to the component provider
- the Availability targets don't change in case the plan is invoked.
- recovery requirements:
- Maximum tolerable period of disruption (MTPoD) (the maximum amount of time that a service can be unavailable or undelivered after an event that causes disruption to operations, before its stakeholders perceive unacceptable consequences): 5 days
- Recovery time objective (RTO) (the acceptable amount of time to restore the service in order to avoid unacceptable consequences associated with a break in continuity (this has to be less than MTPoD)): 3 days
- Recovery point objective (RPO) (the acceptable latency of data that will not be recovered): n.a.
- approach for the return to normal working conditions as reported in the risk assessment.
Availability and Continuity test
The critical level of this service is low.
Taking into account the availability and continuity measures adopted by the provider, and considering that the VOMS and MyProxy services are quite easy to install, we don't require a continuity/recovery test for this service: the team has extensive experience with VOMS and is able to to install a new instance rapidly if it's needed.
