  from their new maintainers.Docker MachineDocker Machine was a tool for provisioning and managing Docker hosts across
  various platforms, including virtual machines and cloud providers. It is no
  longer maintained, and users are encouraged to use
  Docker Desktop
  or
  Docker Engine directly on supported platforms.
  Machine's approach to creating and configuring hosts has been superseded by
  more modern workflows that integrate more closely with Docker Desktop.Docker ToolboxDocker Toolbox was used on older systems where Docker Desktop could not run. It
  bundled Docker Machine, Docker Engine, and Docker Compose into a single
  installer. Toolbox is no longer maintained and is effectively replaced by
  Docker Desktop on current systems. References to
  Docker Toolbox occasionally appear in older documentation or community
  tutorials, but it is not recommended for new installations.Docker Cloud integrationsDocker previously offered integrations for Amazon's Elastic Container Service
  (ECS) and Azure Container Instances (ACI) to streamline container workflows.
  These integrations have been deprecated, and users should now rely on native
  cloud tools or third-party solutions to manage their workloads. The move toward
  platform-specific or universal orchestration tools reduced the need for
  specialized Docker Cloud integrations.You can still view the relevant documentation for these integrations in the
  Compose CLI repository.Docker Enterprise EditionDocker Enterprise Edition (EE) was Docker's commercial platform for deploying
  and managing large-scale container environments. It was acquired by Mirantis in
  2019, and users looking for enterprise-level functionality can now explore
  Mirantis Kubernetes Engine or other products offered by Mirantis. Much of the
  technology and features found in Docker EE have been absorbed into the Mirantis
  product line.
  NoteFor information about enterprise-level features offered by Docker today,
  see the
  Docker Business subscription.Docker Data Center and Docker Trusted RegistryDocker Data Center (DDC) was an umbrella term that encompassed Docker Universal
  Control Plane (UCP) and Docker Trusted Registry (DTR). These components
  provided a full-stack solution for managing containers, security, and registry
  services in enterprise environments. They are now under the Mirantis portfolio
  following the Docker Enterprise acquisition. Users still encountering
  references to DDC, UCP, or DTR should refer to Mirantis's documentation for
  guidance on modern equivalents.Dev EnvironmentsDev Environments was a feature introduced in Docker Desktop that allowed
  developers to spin up development environments quickly. It was deprecated and removed
