System Requirements

This section details the minimum system resources required to host the LaborMate backend services. System resources must be customized based on number of concurrent users, CPU load, memory and disk space required to meet expected performance by the application.

Operating System	Canonical Ubuntu 24.04-2024.10.09-0 or above, 64-bit
CPU	AMD EPYC 7742 64-Core Processor (or Intel chipset based) 2 Core (Physical)
RAM	8 GB
Hard Disk	20 GB Applicable for OS and system files. Hard disk space must be increased based on need/demands of the project.
Network	100 mbps/Gigabit Ethernet Adapter
Minimum RAM for Docker	3 GB
Internet Access	Required Server setup requires packages to be downloaded from the internet.

The specification (RAM and Processor) is for 50 users. For higher number of users, RAM and Processor need to be scaled up as needed.
