Future Infrastructure (in planning)
Principles
consistent production lines
Minimize admin costs
optimize performance
data integrity
Server-Options
assumption:
one server = one IP, one operating system (LINUX WindowS nAP LOCAL )
one cell = one instance on a server
no distributed resources
Minimal Sizing:
WINDOWS 2 : 4core, 16GB, root server, dedicated
LINUX 2 : 4core, 16GB, root server, dedicated
Free BSD : as virtual machine on LINUX 2 (to be verified)

Discussion
look at loads
Modular doesn’t need windows server
managed server or root server
lines:
develop: own computers, online DB for testing
training: several instances on one server (same IP, different ports/ subdomains)
Draft architecture
Timeline
Step 1 (January): Transfer openIMIS Develop & Demo - ( develop.openIMIS.org, demo.openIMIS.org )
Step 2 (February): Install openIMIS Release - (release.openIMIS.org)
Other environments as needed
Server config based on:
Data Replication between servers https://www.programmersought.com/article/92226036787/
Virtual machine hosting
cockpit
linux firewall : firewalld
basic security for ssh: fail2ban
