Server Architecture
Notice
Depending of the customers use-case, an OTH installation can take on different configurations. Below is an outline of the most commonly used setups. Network architecture
The load-balancer node should be the only node placed in a DMZ, with a public facing interface exposed to the Internet and a local LAN (rfc1918) interface, facing the application nodes and the database/storage node network. Application nodes and database nodes should be configured with local LAN (rfc1918) interfaces only.
Test/Demo or low volume production setup
Use-case
Typical use-case for test and demo setups are, testing clinical flows, trying out new releases, education, pilot trial runs, development or production setup with a low volume of patients/measurements.
Node requirements
| Node role | Node count | Additional info |
|---|---|---|
| Frontend | 1 | Mandatory |
| Application | 1 | Mandatory |
| Storage/DB | 1 | Optional See requirements for further info |
Normal scale production
Use-case
Typical use-case for normal scale production. Application servers could be setup as one large node, by scaling up on vCPU and Memory.
Node requirements
| Node role | Node count | Additional info |
|---|---|---|
| Frontend | 1 | Mandatory |
| Application | 2 | Mandatory |
| Storage/DB | 1 | Optional See requirements for further info |
Large scale production
For larger scale production setups, add additional application nodes and if needed additional frontends.
