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.

Previous plans are collected here: https://documents.egi.eu/secure/ShowDocument?docid=3538

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 EOSC AAI and EGI Checkin
  • the service is also accessible with a certificate by using "IGTF Proxy certificate" in AAI
  • a web service is also exposing information through REST API

The service availability is regularly tested by nagios probe org.nagiosexchange.OpsPortal-WebCheck: https://argo-mon.egi.eu/nagios/cgi-bin/status.cgi?servicegroup=SERVICE_egi.OpsPortal&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 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.

Risks analysis

 to update 
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 Cluster web / Databases / Lavoisier RENATER has redundant network connectivity Medium less than 1 hour the measures already in place are considered satisfactory and risk level is acceptable
2 Service unavailable / loss of data due to software failure Cluster web / Databases Web service and databases are hosted on a cluster of machines.The other nodes will continue to work Low less than 10 min the measures already in place are considered satisfactory and risk level is acceptable
3 Service unavailable / loss of data due to software failure Lavoisier Lavoisier configuration is stored centrally . One machine could be restarted with the same configuration in 15 min.The interruption is short . Medium less than 20 min the measures already in place are considered satisfactory and risk level is acceptable
4 service unavailable / loss of data due to human error Lavoisier Lavoisier configuration is stored centrally . One machine could be restarted with the same configuration in 15 min.The interruption is short . Medium less than 20 min the measures already in place are considered satisfactory and risk level is acceptable
5 (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 Medium 1 working day the measures already in place are considered satisfactory and risk level is acceptable
6 Unavailability of key technical and support staff (holidays period, sickness, ...) Cluster web / Databases No measures Medium 1 or more working days The occurrence of this risk can be critical since there are no measures in place. It is necessary to discuss with the provider some countermeasures to implement.
7 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 Medium less than 1 hour the measures already in place are considered satisfactory and risk level is acceptable
8 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. Medium 1 working day the measures already in place are considered satisfactory and risk level is acceptable
9 (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 Medium 1 working day the measures already in place are considered satisfactory and risk level is acceptable

Countermeasures to improve

 to update 

The risk number 4 doesn't have countermeasures in place and needs to be handled.

The provider will try to avoid, where possible, that the people in the staff take vacations at the same time. All the staff can access remotely to the services in case of need.

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): 2 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)): 1 day
-- 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.

Availability and Continuity test

 to update 

The proposed A/C test will focus on a recovery scenario: the service has been disrupted and needs to be reinstalled from scratch.

We have made the test for the Lavoisier Component .

To simulate the disruption it was

- stopped the lavoisier service
- deleted the repository with the lavoisier configuration

Then for the recovery part :

- Get the lavoisier engine - wget a zip file and unzip it
- Get the local configuration -  git clone 
- Add properties: passwords and sensitive information - stored in gitlab variables
- Add the certificate - locale copy from laptop 
- Restart the service
  • Duration : ~ 8 min
  • Start : Thu Nov 8 14:10:26 CET 2018
  • End : Thu Nov 8 14:18:49 CET 2018

The recovery test can be considered successful since restoring the service after a disruption to the Lavoisier component took very few time, well inside the Maximum tolerable period of disruption for this service.
