### Orchestration
The portability and reproducibility of a containerized process mean we have
an opportunity to move and scale our containerized applications across
clouds and datacenters; containers effectively guarantee that those
applications will run the same way anywhere, allowing us to quickly and
easily take advantage of all these environments.
Furthermore, as we scale our applications up, we'll
want some tooling to help automate the maintenance of those applications,
able to replace failed containers automatically and manage the rollout of updates
and reconfigurations of those containers during their lifecycle.
Tools to manage, scale, and maintain containerized applications are called
_orchestrators_, and the most common examples of these are _Kubernetes_ and
_Docker Swarm_. Development environment deployments of both of these
orchestrators are provided by Docker Desktop, which we'll use throughout
this guide to create our first orchestrated, containerized application.
## Install Docker Desktop
The best way to get started developing containerized applications is with Docker Desktop, for OSX or Windows. Docker Desktop will allow you to easily set up Kubernetes or Swarm on your local development machine, so you can use all the features of the orchestrator you're developing applications for right away, no cluster required. Follow the installation instructions appropriate for your operating system:
