Purpose
The purpose of this document is to outline the requirements for a virtual machine (VM) to replicate a specific server environment for Production purposes and to provide guidance on hardware specifications based on node counts.
Functional Requirements
Operating System: Ubuntu 22.04.05 LTS
Network Configuration: Enable network connectivity to internal resources and the internet
Performance Requirements (Baseline)
CPU: Minimum of 2 CPU cores with 2.5 GHz clock speed or better
Memory: Minimum of 8 GB RAM
Disk Space: Minimum of 350 GB
Networking and Connectivity
Networking: Ensure the VM can communicate with the internal network and the internet
Ports to Allow:
SSH → Port 22
HTTP → Port 80 (optional)
HTTPS→ Port 443
TFTP → Port 69
COAP → Port 5683
MQTT →1883
MQTTS→ 8883
VM Requirements Based on Node Count
| Node Count Range | Operating System | RAM | Hard Drive |
|---|---|---|---|
| Less than 250 Nodes | Ubuntu 20.04.6/22.04.05 LTS | 8 GB | 200 GB |
| 250–500 Nodes | Ubuntu 20.04.6/22.04.05 LTS | 8 GB | 300 GB |
| 500–1000 Nodes | Ubuntu 20.04.6/22.04.05 LTS | 16 GB | 400 GB |
| 1000–2000 Nodes | Ubuntu 20.04.6/22.04.05 LTS | 16 GB | 500 GB |
| 2000-3000 Nodes | Ubuntu 20.04.6/22.04.05 LTS | 32 GB | 1 TB |
Notes
Specifications are based on standard requirements and may need adjustments depending on specific workloads and use cases.
Regular monitoring and scaling may be required as node counts and workloads increase.
