Availability

247

Backup (what, frequency, retention period)

none

Monitoring and alerting1

Nagios instance provided by SUNET for monitoring of the VMs

Status.io for creating public status pages

Pingdome.org for monitoring of webpages from various locations

Measuring and Reporting2

Usage can be measured by looking at traffic from CDN.

Log retention3

No logs are kept.

Security policy for access and usage4

Security groups (openstack or equivalent) or external FW. 

Rules will be defined.

1As the minimum, network accessibility (outside of LAN) and hardware resource usage must be monitored. Indicate if some of these resources can be deemed critical so that adequate thresholds for alerting are implemented. Additional, indicate which specific applications uptime and operational health must be monitored and alerting implemented.

2Define what should be measured, how and with what period in order to deliver appropriate reporting relating to KPIs, usage, etc.

3Define which logs should be kept in order to have debugging data and data in case of misuse of the service, and how long logs should be retained.

4Define the policy for limiting access to the piece of the infrastructure and where it should be implemented (system level, network level etc.)

System and Application Maintenance Requirements

Indicate requirements for system and application maintenance, scoping by the indicated infrastructure elements, as necessary.

Total budget:

  • Manpower: 12 + 14,4 = 26.4MM
  • CDN: 10Ke

Used till November 2019

CDN parked 10K 

Used in first 10 months in 2019, hours: Fresia 80, Maria 84, Leif 136  = Total is 300h, which is 2MM 

Left over: 26.4-2=24.4MM

  • This leaves 5.4 MM, that is 37KE = 10KE goes to CDN and 

Need budget, starting November 2019:

  • For remaining time needed 50% FTE, over 38MM, that is 19MM.
  • CDN, estimate at 20Ke
  • pingdom 69e per month = starting January 2019 over 36 months total is 2484 eur
  • status.io 79 dollar per month = starting January 2019 over 36 months is 2559 eur
  • VMs, 200e per month ?? = starting January 2019 over 36 months is 7200 eur
