ArchitectureΒΆ

Murano is composed of the following major components:

  • murano command-line client
  • murano-dashboard
  • murano-api
  • murano-engine
  • murano-agent

They interact with each other as illustrated in the following diagram:

Murano architecture

All remote operations on users’ servers, such as software installation and configuration, are carried out through an AMQP queue to the murano-agent. Such communication can easily be configured on a separate instance of AMQP to ensure that the infrastructure and servers are isolated.

Besides, Murano uses other OpenStack services to prevent the reimplementation of the existing functionality. Murano interacts with these services using their REST API through their python clients.

The external services used by Murano are:

  • the Orchestration service (Heat) to orchestrate infrastructural resources such as servers, volumes, and networks. Murano dynamically creates heat templates based on application definitions.
  • the Identity service (Keystone) to make murano API available to all OpenStack users.
