Service Availability and continuty plan structure

- Performances (A/R targets agreed in the OLA, comment about the past behaviour and any particular issue)

- summary of the risks assessment

- Av.Co. tests and results

Introduction

This page reports on the Availability and Continuity Plan for the Operations 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 likely of the occurrence of a risk, 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.

Performances

The performances reports in therms of Availability and Reliability are produced by ARGO on an almost real time basis and they are also collected every 6 months into the Documentation Database (last period July 2017 - December 2017.

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

  • Availability 99%
  • Reliability 99%

Over the past years, the Operations 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.


Risk id Risk description Affected components Established measures Risk level Expected duration of downtime Comment
1 External network connectivity outage. Network outage with causes external of the site (e.g. internet provider outage) Cluster web / Databases / Lavoisier RENATER has redundant network connectivity text text text
2 Hardware failure Cluster web / Databases Web service and databases are hosted on a cluster of machines.The other nodes will continue to work text text text
3 Hardware failure Lavoisier Lavoisier configuration is stored centrally . One machine could be restarted with the same configuration in 15 min.The interruption is short . text text text
4 Unavailability of key technical and support staff (holidays period, sickness, ...) Cluster web / Databases No measures text text text
5 Major disruption in the data centre. Fire, flood or electric failure for example Cluster web / Databases The computing centre has electric backup system and fire control devices text text text
6 Major security incident. The system is compromised by external attackers and needs to be reinstalled and restored. Cluster web / Databases / Lavoisier The backend database store is operated in clustered mode with backups. The code is stored in Gitlab and stored in backup files . Lavoisier is stateless and does not store historical datas. So there is no problem to start a new Operations Portal from backup and new machines. text text text
7 (D)DOS attack. The service is unavailable because of a coordinated DDOS. Cluster web / Databases RENATER and local team network provides protection for DOS attacks, firewall can limit impact of the DDoS text text text
