General
Try to get machines with ethernet connections, not usb connections.
Tier 1 — Core / Production Nodes
Hardware Definition
CPU: i7 / Ryzen 7+ (or strong i5 10th gen+) RAM: 16–64 GB Storage: NVMe / SSD (required) Network: Gigabit+
Role
Production workloads Databases (Postgres, etc.) Multi-service nodes 24/7 access required because public facing Failure impact is high, response is prevent, have warm back ups
Inference Nodes
Its a factor of GPU, memory, networking across GPUs to handle the inference, power and thermal, and distribution across centralized heavy servers, edge devices and sensors
Tier 2 — Utility / Service Nodes
This is your sweet spot expansion layer.
Hardware Definition
CPU: i5–i7 (4th gen minimum, ideally 6th–8th gen+) RAM: 8–16 GB Storage: SSD preferred OR easily upgradeable
Role
Single-purpose services Internal tools Control-plane systems Examples (your current direction): Mail system ✅ Internal APIs Dev/staging environments Job schedulers Small databases One machine = one primary responsibility Failure tolerance is medium, response is recover, warm back up available, if possible
Tier 3 — Edge / Background Nodes
These are not “bad machinesâ€â€”they are specialized low-duty nodes.
Hardware Definition
CPU: i3 / old i5 / low-end chips RAM: 4–8 GB Storage: anything (SSD preferred but not required) Role Monitoring Logging Heartbeats / uptime checks Lightweight automation Backup triggers Examples: Replace / augment your Raspberry Pi Network watchers Alert systems Failure tolerance is low, response is ignore, if it fails, junk it, but have others ready to spin up to replace.
