 ## All-In-One vs Split Service mode
 
-Pomerium's default mode is all-in-one mode. It run all the individual [components](/docs/internals/architecture#component-level) in a single container or under a single system service. This is our suggested way to run Pomerium. Alternatively, each of those component services can be configured and run separately in split mode.

-All-in-one mode has the easiest configuration and successfully used in large production environments. All the configuration goes in a single `config.yaml` file or single set of environment variables. When running Pomerium as a single system service or container, all the options on this page can be set in a single `config.yaml` file, or passed to the single instance as environment variables. Internal communication is configured automatically requiring no additional setup.

-Alternatively, each component can be run separately in split-mode using the [service mode](/docs/reference/service-mode) key to specify which component to run. Each of these needs to be configured separately, and communication between components must be explicitly configured including managing tls certificates.
