Infrastructure Requirements
Indicate requirements for servers, VMs or containers, grouping the requirements for multiple VMs in one column. Add as many columns as necessary, adding the sensible distinguisher for each group that will enable its later identification.
| VM requirements | Backend Site Metadata servers per site (at least 4 sites). One more site for QA/Testing | ||
|---|---|---|---|
| Description of usage | MDQ | Metadata aggregation | HA Proxy |
| Number of VMs with same specification | 2 | 1 | 1 |
| Hardware requirements (CPU, RAM, disk space) | 2 vCPU, 16G, 20G disk | 2 vCPU, 16G, 20G disk | 2 vCPU, 16G, 20G disk |

Infrastructure Hosting Requirements
Hosting requirements | Applying to Backend Site Metadata servers per site (at least 4 sites) |
|---|---|
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.)

Budget Requirements
Original Budget
| Erik | Bergstöm | NORDUnet (SUNET) | berra@nordu.net | Task 1- RA21 | eduGAIN RA21 operations | 12 |

| Elena | Rakhimova | KTH (SUNET) | elenara@kth.se | Task 1- RA21 | eduGAIN RA21 front developer | 7.2 |
| Leif | Johansson | NORDUnet (SUNET) | leifj@sunet.se | Task 1- RA21 | eduGAIN RA21 | Using up the underspent of sunet - for first 5 months there was already 2.65 MM underspent |
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
New Budget, starting November 2019
