note right of linode_vps

  • Single point of failure

  • Minimal functional phase

  • Limited budget constraints

end note

note right of titan

  • IMAP: imap.titan.email

  • SMTP: smtp.titan.email

  • Requires manual config

end note

note bottom of security

  • KeePassXC database

  • Sync via WebDAV

  • Currently self-signed cert

AI Request (TODO - find a way to standardize AI prompts):

Help me create a PlantUML diagram to reflect the current status of the architecture for Kusala Tech.

Context:

- name.com for NS (kusala.studio)

- email on Titan Mail (service of name.com)

  - imap.titan.email

  - smtp.titan.email

  - NOTE: they need to be configured manually (autodiscovery does not currently work - ref for configuration can be found at: https://support.titan.email/hc/en-us/articles/900000215446-Configure-Titan-on-other-apps-using-IMAP-POP)

- Linode VPS (foss-dev)

  - Note: this is a single point of failure, but there is not anything currently highly critical, and we are in minimal functional phase with limited to no budget.

  - Docker

    - Traefik

    - Redmine

    - Certbot will be configured for TLS

- KeepassXC for password management

  - Sync over WebDAV

    - Tested - works nicely (currently self-signed cert)

- Linode LKS (for later migration if necessary)
