- Some base services that are available to code hosted by the runtime. This varies by runtime.
- Additional constraints. For example, the CLI client runtimes limit the libraries that are available to the code in that runtime, for performance reasons. 

Other modules and platforms define the services that they contribute to the runtime.

* There are 4 minio distributed instances created by default. You can add more MinIO services (up to total 16) to your MinIO Compose deployment. To add a service
  * Replicate a service definition and change the name of the new service appropriately.
  * Update the command section in each service.
  * Add a new MinIO server instance to the upstream directive in the Nginx configuration file.
