High availability
There are three key components in Datalore's architecture that might require to be highly available:
Datalore server
Datalore backend database
Notebook agents
Below are the main considerations on making Datalore highly available.
- Datalore server
Currently, due to Datalore's architecture, it is impossible to run multiple instances of the Datalore server at the same time. Consequently, a multi-region (or multi-AZ) deployments within the public clouds are also not available.
We're well aware of this limitation and looking into possible mitigation options.
warning
Attempting to run more than one server using the same database and/or storage volume may lead to a malfunction or data loss.
- Datalore backend database
By default, Datalore is shipped with a single-node PostgreSQL database. While it can be operated within the production environments, we recommend you to deploy a dedicated PostgreSQL cluster, configured properly according to the PostgreSQL operation manual.
Alternatively, a managed database solution like Amazon RDS could be used.
