# Concepts

- [Workspaces](https://docs.iotify.io/concepts/workspaces.md): Collaborate with your team with workspaces
- [Role Based Access Control (RBAC)](https://docs.iotify.io/concepts/workspaces/role-based-access-control-rbac.md)
- [Invitation Management](https://docs.iotify.io/concepts/workspaces/invitation-management.md)
- [GitHub Integration](https://docs.iotify.io/concepts/workspaces/github-integration.md)
- [Deletion of Workspaces](https://docs.iotify.io/concepts/workspaces/deletion-of-workspaces.md)
- [System Status](https://docs.iotify.io/concepts/workspaces/system-status.md)
- [Understanding Tests](https://docs.iotify.io/concepts/understanding-a-test.md): A test is a JavaScript document which describes the behaviour of your virtual device during simulation. Tests consist of Device Model, Library Management, Protocol Settings and Security Parameters.
- [Stages Management](https://docs.iotify.io/concepts/understanding-a-test/stages-management.md)
- [Init Stage](https://docs.iotify.io/concepts/understanding-a-test/stages-management/init-stage.md): Initialise the devices and add default values
- [Running Stage(s)](https://docs.iotify.io/concepts/understanding-a-test/stages-management/running-stage.md): The majority of the device logic is written in the running state(s). These stages must return a payload to be sent to the server.
- [Finished State](https://docs.iotify.io/concepts/understanding-a-test/stages-management/finished-state.md)
- [Generating Messages](https://docs.iotify.io/concepts/understanding-a-test/generating-messages.md)
- [Scripting Environment](https://docs.iotify.io/concepts/understanding-a-test/generating-messages/scripting-environment.md)
- [State Object](https://docs.iotify.io/concepts/understanding-a-test/generating-messages/state-object.md)
- [Response Handler](https://docs.iotify.io/concepts/understanding-a-test/response-handler.md)
- [Preview Tests](https://docs.iotify.io/concepts/understanding-a-test/preview-tests.md)
- [Exporting/Importing Tests](https://docs.iotify.io/concepts/understanding-a-test/exporting-importing-tests.md)
- [Import OpenAPI JSON/YAML](https://docs.iotify.io/concepts/understanding-a-test/exporting-importing-tests/import-openapi-json-yaml.md)
- [Locking/Unlocking a test](https://docs.iotify.io/concepts/understanding-a-test/locking-unlocking-a-test.md)
- [Stateful Simulation](https://docs.iotify.io/concepts/stateful-simulation.md)
- [Mapping the IoT device lifecycle](https://docs.iotify.io/concepts/stateful-simulation/understanding-the-device-lifecycle.md): One of the first step to get started with IoT simulation is to map your device lifecycle into states and events.
- [Protocol Settings](https://docs.iotify.io/concepts/protocol-settings.md): IoTIFY Supports multiple protocols to connect with cloud platforms. Let's discuss each of these protocols in detail.
- [MQTT](https://docs.iotify.io/concepts/protocol-settings/mqtt.md): MQTT is the most widely used and known protocol for IoT devices. Let's have a basic look at MQTT and how could we use it with IoTIFY
- [HTTP](https://docs.iotify.io/concepts/protocol-settings/http.md): Many of the IoT devices also use HTTP as a connectivity option. Let's see what HTTP parameters could be configured.
- [Using other protocols](https://docs.iotify.io/concepts/protocol-settings/using-other-protocols.md)
- [Run Settings](https://docs.iotify.io/concepts/run-settings.md): Once the device model has been finalized, the run settings define the parameters regarding the simulation of the devices.
- [Network Simulation](https://docs.iotify.io/concepts/run-settings/network-simulation.md)
- [Execution Strategies](https://docs.iotify.io/concepts/run-settings/execution-strategies.md)
- [Client Distribution](https://docs.iotify.io/concepts/run-settings/client-distribution.md)
- [Scenarios](https://docs.iotify.io/concepts/scenarios.md)
- [Glob Storage](https://docs.iotify.io/concepts/glob-storage.md)
- [Metrics](https://docs.iotify.io/concepts/metrics.md)
- [Mailbox](https://docs.iotify.io/concepts/mailbox.md)
- [Licensing and Limits](https://docs.iotify.io/concepts/licensing-and-limits.md)
- [Deployment Models](https://docs.iotify.io/concepts/deployment-models.md): This page details the deployment options available for IoTIFY
