Hardware Requirements

The edge gateway runs the Fleetera Edge Runtime and its companion containers in Docker. The hardware requirements depend on the number of connectors, data points, and collection frequency.

Minimum specifications

Component	Minimum	Recommended
CPU	Dual-core	Quad-core
RAM	2 GB	4 GB or more
Storage	16 GB available	32 GB or more
Network	Stable internet connection	Wired Ethernet preferred
OS	Linux with Docker support	Ubuntu 22.04 LTS or newer

Supported architectures

Architecture	Value	Description
amd64	`amd64`	Intel and AMD 64-bit processors. Most industrial PCs, servers, and desktop machines.
arm64	`arm64`	ARM 64-bit processors. Raspberry Pi 4/5, industrial ARM single-board computers.

Select the architecture that matches your edge hardware when creating the deployment.

Tested hardware

The following hardware has been tested with Fleetera edge deployments:

Device	Architecture	RAM	Notes
Raspberry Pi 4	arm64	4 GB / 8 GB	Good for small sites with fewer data points
Raspberry Pi 5	arm64	4 GB / 8 GB	Improved performance over Pi 4
Intel NUC	amd64	8 GB+	Good for medium-sized sites
Industrial PCs (OnLogic, Advantech)	amd64 / arm64	8 GB+	Recommended for production deployments

Network requirements

Internet access — required for VPN connectivity, Docker image downloads, and cloud communication
Local network access — required for connecting to industrial data sources (OPC UA servers, Modbus devices, etc.)
No inbound ports — the VPN mesh handles all connectivity without requiring inbound firewall rules
Bandwidth — minimal for telemetry data (typically a few KB/s per data point). The bootstrap process downloads a small set of Docker images (a few hundred MB in total).

Storage considerations

Docker images — the stack is compact: the Fleetera Edge Runtime (a single Go service), the Edge Crawler, and the Watchtower auto-updater. Automatic updates keep a second copy of an image on disk briefly during a rollout.
Local data buffer — the runtime's store-and-forward buffer holds telemetry on disk while the cloud is unreachable. Buffer limits are configurable per deployment; size your storage to cover the longest outage you want to bridge.
Logs — Docker container logs accumulate over time; configure log rotation
OS and system — reserve at least 4 GB for the operating system

For long-running deployments, 32 GB or more of storage is recommended to accommodate the store-and-forward buffer, log growth, and image updates.

Operating system

Any Linux distribution that supports Docker is compatible. Tested distributions:

Ubuntu 22.04 LTS and newer
Debian 11 and newer
Raspberry Pi OS (64-bit)

The bootstrap script installs Docker automatically if it is not already present.
