Certainly OTDT could be operated in a high availability setting for (Production, …) Site Automation and the so called Industry 4.0.
- An high available MongoDB Cluster
- An HAProxy
- At least 2 different machines with OTDT installed and ready to run
To run OTDT in a high availability setting you will need to run OTDT in Stateful Operation mode. This means that you do need a storage for the State Store. It is strongly recommended to use MongoDB for this. Additionally the lock of the State Store will get managed using MongoDB as well.
# Key Value Store
# If you need a cert for the connection
# State Store
# use "single" if you run into piling
