You can run Zammad on bare metal or on a virtual machine. Choose what you prefer.
For Zammad and a database server like PostgreSQL we recommend at least:¶
- 2 CPU cores
- 2 GB of RAM (+2 GB if you want to run Elasticsearch on the same server)
For optimal performance up to 40 agents:¶
- 4 CPU cores
- 4 GB of RAM (+4 GB if you want to run Elasticsearch on the same server)
Of course at the end it depends on acutal load of concurent agents and data traffic.
