# Introduction to the Hybrid Runner

Unlock the power of [Coherent Spark](https://www.coherent.global) and seamlessly deploy your logic on-premises, private clouds, or personal devices! Coherent Spark includes the groundbreaking capability that leverages WebAssembly (or [Wasm](https://webassembly.org/)) technology as a secure sandbox to execute near-native code.

Our platform takes Excel spreadsheet logic to new heights by converting it into efficient C++ code, which is then encapsulated into WebAssembly modules. This innovative approach empowers users to package and deploy their Excel-based applications within [Docker](https://docs.docker.com/manuals/) containers.

## Key features

1. **Privacy and security**: Coherent Spark ensures the protection of sensitive data, making it an ideal choice for applications handling personally identifiable information (PII). The WebAssembly sandbox provides a secure environment for executing your logic, safeguarding your data at every step.
2. **On-premise scalability**: Take control of your computing resources with on-premise deployment. This option allows you to scale and optimize your infrastructure according to your specific needs.
3. **Low-latency performance**: Experience fast performance with our [Neuron](https://docs.coherent.global/build-spark-services/neuron) runner and guarantee low-latency results for your applications.
4. **Telemetry tools**: Support for [OpenTelemetry](https://opentelemetry.io/docs/what-is-opentelemetry/) to enable logging of service status and API calls.

## How it works

The Spark team has created and provided a Docker image [`nodegen-server`](https://github.com/orgs/Coherent-Partners/packages/container/package/nodegen-server) (also referred to as the Neuron runner) to create and run containerized applications designed explicitly for executing Wasm modules generated by Spark.

Use the [ImpEx APIs](/spark-apis/impex-apis.md) to export Wasm modules from Spark. These modules, along with the [`nodegen-server`](https://github.com/orgs/Coherent-Partners/packages/container/package/nodegen-server), can be neatly packaged into [Docker](https://docs.docker.com/manuals/) containers. This process is designed with continuous integration/continuous delivery (CI/CD) in mind, ensuring a streamlined and automated deployment process.
