# Overview ## What is Cake Red? It's managed Node-RED inside your Datacake Workspaces. You can purchase Cake Red through an in-portal purchase as a monthly subscription to your workspace. During activation, a separate, self-contained server is provided on which node Red and other components are automatically installed. ## Firewall Cake Red has an advanced firewall. This allows among other things: * Own whitelisting for URLs (for own APIs) * Port forwarding for UDP and TCP (for incoming server services) ## Public URL Your server is accessible via its own Cake Red URL. This is structured as follows: {% embed url="" %} This is just a demo URL - This is what your URL would look like {% endembed %} You can use this URL for the following services: * Hosting the Node-RED Dashboard * Deployment of your own REST-API * Accept incoming connections ## Pricing Cake Red is available as an optional subscription within your Datacake Workspaces. It costs: 49**,-€** per Month and per Workspace (excl. VAT). ![](https://2221155863-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LNA8_b8wmabHgJ0QXoJ%2F-M7D4lBqV76JNLL-C4pr%2F-M7DEpG7YFAA_gT6Y0B1%2FBildschirmfoto%202020-05-13%20um%2015.33.24.png?alt=media\&token=97941bee-2ca5-4f12-a184-e95ab1a9435f) For this you get: * Dedicated Virtual Server (non shared) * 1 Virtual CPU * 1 GB RAM * 1 TB Traffic per Month * 25 GB SSD * Unlimited Node-RED * 24/7 Runtime * Fully upgradable (can install extensions) * Your own Public URL ## FAQs ### Can I share one Instance between multiple Workspaces? No. But you can share Devices between Workspaces. So you could create Devices in the Workspaces where Cake Red is installed and create a Flow here that controls the devices. If you want to share this device with other members you can create a separate Workspace and make this device also available through Claiming: {% content-ref url="../device/claiming" %} [claiming](https://docs.datacake.de/device/claiming) {% endcontent-ref %}
