Introduction

This page reports on the Availability and Continuity Plan for the ARGO 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.

Availability requirements and performances

In the OLA it was agreed the following performances targets, on a monthly basis:

  • Availability: 99%
  • Reliability 99%
 Other availability requirements:
- the service is accessible through X509 certificate and/or other authentication system 
- The service is accessible via CLI and/or webUI (link to the probes that checks the authentication and the service in general)
- (depending on the service, specific requirements can be identified. In case, for each requirement report what is the action/measure in case of failure)

The service availability is regularly tested by nagios probes org.nagios.ARGOWeb-AR and org.nagios.ARGOWeb-Status: https://argo-mon.egi.eu/nagios/cgi-bin/status.cgi?host=argo.egi.eu&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, the Accounting Portal 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.

Outcome

Additional information

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

- 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): 1 day
-- 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)): 2 days
-- Recovery point objective (RPO) (the acceptable latency of data that will not be recovered): 2 days

- approach for the return to normal working conditions as reported in the risk assessment.

- The GGUS Support Unit "ARGO/SAM EGI Support" will 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.
