## New Features

### Nebula Cloud Clusters

With [GridGain Nebula](https://www.gridgain.com/docs/nebula/about/overview) you can quickly deploy GridGain clusters in AWS cloud, and have GridGain support team manage them. All Nebula environments are configured for up to 99% availability.

### Code Deployment

With the new Code Deployment feature, you can deploy your code dependencies on the clusters. To do this, you create **Deployment Units** in the Code Deployment screen.

Each deployment unit contains dependencies that are sent to the passed to the cluster and stored in the metastorage. When you deploy your code, all nodes in the cluster will download it at the same time, and make it possible to execute your code much easier.
