The document discusses disaggregated data centers using OpenNebula. It describes how OpenNebula allows for scalability through elasticity and avoids issues from human/configuration errors. It discusses types of scalability like predictable, mixed/emergency, and unpredictable scalability. It also briefly discusses provisioning tools like Oneprovision and using provision templates in YAML format.

12. Game Approaches

13. Game Approaches and tools
● Visual Studio
● .NET
● mono
● dotnetcore
● perforce
IMPORTANT: CPU cores usage and HT

14. Crytek Approach

15. Crytek Approach
● dotnetcore - official
● Minimize attack surface from beginning
● IntelliTrace, software transactional memory (STM) and Pex
● Isolation and White Box Unit Testing
● Workflow - CERT

17. Behind the Game

18. Behind the game - OS
● Linux OS Standardization (according to req)
● Additional security configuration for repository signatures
● LVM configuration - different schemes per server purpose
● FDE / Partition encryption
● Ulimits settings
● Kernel / Network stack tuning
● CPU and IO schedulers patches and tuning
Nice to read about: oomd, earlyoom, nohang

19. Behind the game - OS
● Spectre / Meltdown mitigations (retpoline)
● Latest CPU microcode
● Kernel mitigations
● GCC (fstack-clash-protection | mindirect-branch)
● Userspace (qemu / libvirt)

20. Behind the game - OS
Linux Security Modules (LSM)
AppArmor |
SELinux |
TOMOYO
LoadPin
Smack
Yama
SafeSetID

21. Monitoring
● Zabbix + Zabbix proxy + zabbix.dll (server integration)
● Zabbix autodiscovery for every HW server
● Vulns - CVE across installed packets - integration with Zabbix
● Kibana (ELK)
● Graphana
● Monit
● Graphite
● Graylog

22. Monitoring 2
● rsyslog (official repos, not distro)
● Logwatch
● Gitlab for all configuration files (both game and /etc)
● cachet (for status page)

23. HW / Net capacity tracking
● OpenDCIM - racks map and interconnection
● IPAM - IP Address Management
● Eramba - GRC (+compliance)

24. Compliance
● DISA STIG’s
● NIST SP (800x)
● SCAP / OpenSCAP

25. Access

31. Datacenter APIs

32. Datacenter API
How datacenter API should be provided (via official libraries):
● CLI
● Python
● Ruby
● Node.js
● PHP
● Go, etc...

33. Own integration
Something like:
● Flask, Flask-RESTPlus and Swagger UI

41. Opennebula DDC
(Disaggregated Data Centers)

42. Opennebula DDC
A solution for:
1. Scalability (elasticity) problems
2. Human / configuration errors
3. Time save (big amount of data + configuration at once)
4. P2P
5. Best alternative for cold racks

43. Opennebula DDC
Scalability types:
1. Predictable (Events)
2. Mixed or Emergency
3. Unpredictable

44. Opennebula DDC
About predictable scalability
Metrics, Agreements, Formulas, ELK, Graphana, ingame analytics

45. Opennebula DDC
Mixed / Emergency scalability
Outages, including unplanned + urgent updates

46. Opennebula DDC
Unpredictable scalability
Fast grows and significant exceedances of expected statistical data

48. Provision
● Oneprovision
● Provision templates (YAML)
● IPAM Driver
