Soracom Funk

Serverless cloud function integration that lets device data trigger AWS Lambda, Azure Functions, or Google Cloud Functions without requiring SDKs or credentials on the device.

Trigger cloud functions directly from your devices with no backend to maintain

Soracom Funk forwards device data directly into serverless compute environments like AWS Lambda, Azure Functions, and Google Cloud Functions. This eliminates the need for devices to run cloud SDKs or maintain credentials and removes the operational overhead of building and scaling a custom backend.

Run your application logic in the cloud without adding complexity to your devices

Funk allows devices to send simple HTTP, TCP, or UDP messages to Soracom, which then invokes your cloud function on their behalf. Soracom securely stores and injects the necessary cloud credentials, formats the event payload, and manages retries or errors. That means you can push logic, validation, and processing into your cloud functions—while keeping device firmware fast, lightweight, and battery-friendly.

How it works

Invoke cloud functions directly from devices

Funk passes device data straight into AWS Lambda, Azure Functions, or Google Cloud Functions—removing entire layers of backend routing, SDK handling, and infrastructure management.

Requires no credentials or SDKs on the device

Funk securely manages IAM roles, Azure SAS credentials, and GCP service accounts inside the Soracom platform. Devices only send basic payloads to Soracom, and Funk injects the necessary authentication on the cloud side.

Move logic from firmware into the cloud

Funk lets you offload parsing, validation, routing, or decision logic into cloud functions. This reduces firmware size, speeds up development, and enables instant feature updates without touching deployed hardware.

Why use Soracom Funk for your project?

Reduce firmware logic

Move parsing, routing, and processing into the cloud where updates are easy and instant.

Protect credentials

Keep IAM roles and SAS tokens in the platform instead of storing them on devices.

Scale automatically

Use cloud autoscaling functions instead of building your own backend.

What you’d build without Soracom Funk

A custom API gateway or relay server
You would need to build and maintain a server that receives device requests, validates payloads, and invokes cloud functions manually.

Cloud SDKs and TLS logic inside device firmware
Devices must embed AWS, Azure, or GCP SDKs, run their own TLS clients, and handle cloud authentication directly—adding weight and power usage.

Complex credential distribution workflows
Without Funk, every device must securely store and rotate API keys or certificates, increasing operational and security risks.

Architecture and implementation

Soracom Funk provides a direct, secure path from device to cloud function. Devices send simple payloads via HTTP, UDP, or TCP to a Soracom endpoint. Funk formats the data, injects the appropriate cloud credentials, and invokes your chosen cloud function synchronously or asynchronously depending on platform. Because the function executes application logic in the cloud, teams can update behaviors instantly, test new workflows safely, and build complex pipelines without modifying device firmware.

Real-time event processing in AWS Lambda

Devices send simple JSON or raw bytes to Funk, which invokes Lambda for processing, transformation, or triggering backend workflows.

Azure Functions for telemetry enrichment or validation

Use Funk to deliver data to Azure Functions where you can enrich payloads, apply business rules, or store validated data in downstream services.

Google Cloud Functions for lightweight automation

Funk invokes Cloud Functions directly, enabling automation, notifications, routing, or low-latency decision-making without a traditional backend.

Step 1

Enable Soracom Funk for your SIM group and select your cloud function provider

Open the Soracom User Console and navigate to the SIM group where you want to run serverless functions on incoming device data.

Enable Soracom Funk in the group settings, then choose the cloud function service you want to invoke—such as AWS Lambda, Google Cloud Functions, or Azure Functions.

Funk integrates directly with your cloud account, allowing devices to trigger serverless functions without storing cloud credentials or executing complex client logic.

Setup instructions are available in the Soracom Funk documentation.

Step 2

Connect Funk to your cloud function and configure authentication

Use the User Console to authorize Soracom to invoke your cloud function by providing the required credentials—such as an AWS IAM role ARN, GCP service account details, or Azure function key.

Once configured, Soracom securely handles authentication and invocation on your behalf, eliminating the need to embed secrets or certificates on devices.

You can also specify environment variables, headers, and payload mappings to control how device data is passed into your function.

Integration steps are outlined in the Funk cloud integration guide.

Step 3

Send device data to Soracom and trigger your serverless function automatically

Update your devices to send data using simple HTTP, MQTT, or TCP protocols to the Soracom platform.

Whenever data arrives, Funk automatically invokes your configured cloud function and passes the payload for processing—such as parsing sensor data, running business logic, or writing to a database.

Use your cloud provider’s monitoring tools to review invocation logs, debug function behavior, or measure performance and cost.

Detailed payload formats are described in the Funk payload documentation.

How Soracom Funk works with other Soracom services

Use Funk + Beam for lightweight protocol conversion
Beam handles TLS offload and protocol conversion, then routes formatted requests into Funk for cloud function execution.

Use Funk + Funnel for integrated cloud pipelines
Funnel can ingest bulk telemetry into analytics services while Funk triggers real-time logic for alerts, routing, or decisions.

Use Funk + Door/Canal/Direct for private execution paths
Combine Funk with private networking options to keep sensitive data inside private links all the way into your cloud functions.
