# Data Application Deployment

### Overview

Data Application Deployment is the process that Lenses created to work streaming processing. The Data Application Deployment has a few steps before the application.

Lenses use Kafka Streams as the core streaming engine.

* SQL Processor translation - SQL to Input Parameters
* SQL Processor Configuration Store
* Deploy Unit creation based on input and templates
* Deploy Unit build manifest {Kubernetes}
* Application Containers {Kubernetes}
