Welcome to Cloud Content Delivery (CCD)#

Cloud Content Delivery (CCD) is Unity's managed cloud service that hosts and delivers content to your application’s users worldwide without having to reinstall a new version of the application. The service is fully integrated into the Unity development platform, saving you months of building and maintaining your own similar service. CCD is most valuable for content-rich, live games or applications that require content updates on a regular basis.

CCD interfaces#

There are multiple ways to integrate your application content with Cloud Content Delivery (CCD):

• The command-line interface (CLI) is the recommended interface for interacting with CCD because it's the main mechanism you can use to upload content into a bucket (you can also upload content through the Unity Dashboard or the API).
• The Cloud Content Delivery Dashboard provides the same functionality as the CLI.
• The Content Delivery Management API and Content Delivery Client API allow you to manage application content through programming.
• The CCD Management SDK allows you to manage your CCD content from inside the editor. This pairs with the Addressables package, and allows you to build and release from a single location.

CCD organization#

In CCD, you organize your content into buckets per environment to create a clear workflow for your project. A typical workflow example could be having separate buckets per platform (for example, an iOS bucket and an Android bucket), across multiple environments. You start with a production environment, but you can add other environments such as development and staging.

Within a given bucket, you group specific versions of each asset to create a release. As these versions change, or you add and remove entries, you designate new releases as required.

A release can also have a unique identifier associated with it, called a badge. Give this badge a meaningful name, then use it to query content, and move it between releases to add flexibility to your workflow.

Environments#

You can create environments in the Unity Dashboard. A project can contain multiple environments (such as production, staging and development), but only one of them is the default one. By default, every project has a production environment.

Buckets#

Using Cloud Content Delivery, you organize your content into buckets to create a clear workflow for your project. A bucket is a single context for publishing content. A typical workflow example could be having separate buckets for different platforms, with names such as ios and android. The buckets could be in different environments, such as the production and development environments. A bucket can be private or public. Private buckets protect read access to buckets with an access token, so only those users with that access token can retrieve content from that bucket. You can also mark a bucket as "promotion only" to restrict write access to that bucket and prevent mistakes such as uploading incorrect content to the wrong bucket. The image below shows a sample bucket as it appears in CCD, including its bucket ID, Promotion Only setting, Privacy setting, description, and the details for a release within the bucket.
