# Orchestration and fallbacks
After the Penguin2 crash in Aug. 2022 it has become increasingly clear how hard it is to deploy GeneNetwork. GNU Guix helps a great deal with dependencies, but it does not handle orchestration between machines/services well. Also we need to look at the future.
What is GN today in terms of services
* [X] Main GN2 server (Python, 20+ processes, 3+ instances: depends on all below)
* [X] Matching GN3 server and REST endpoint (Python: less dependencies)
* [X] Mariadb
* [X] redis
* [X] virtuoso (@aruni)
* [X] GN-proxy (Racket, authentication handler: redis, mariadb)
* [X] Alias proxy (Racket, gene aliases wikidata)
* [X] opar server
* [+] Jupyter, R-shiny and Julia notebooks, nb-hub server
* [X] BNW server (@efraimf)
* [+] UCSC browser (@efraimf)
* [X] GN1 instances (older python, 12 instances in principle, 2 running today)
* [ ] Access to HPC for GEMMA (coming)
* [+] Backup services (sheepdog, rsync, borg)
* [+] monitoring services (incl. systemd, gunicorn, shepherd, sheepdog)
* [ ] mail server
* [X] https certificates
* [X] http(s) proxy (nginx)
* [X] CI/CD services (with github webhooks)
* [+] git server (gitea or cgit)
* [X] file server (formerly IPFS)
* [ ] SPARQL endpoint
Somewhat decoupled services:
* [X] genecup
* [X] R/shiny power service Dave
* [ ] biohackrxiv
* [ ] hegp
* [ ] covid19
* [ ] guix publish server (runs on penguin2, needs tux02 @efraimf)
I am still missing a few! All run by a man and his diligent dog.
For the future the orchestration needs to be more robust and resilient. This means:
* A fallback for every service on a separate machine
* Improved privacy protection for (future) human data
* Separate servers serving different data sources
* Partial synchronization between data sources
The only way we *can* scale is by adding machines. But the system is not yet ready for that. Also getting rid of monolithic primary databases in favor of files helps synchronization.
