Metal-as-a-Service (MAAS)

Metal-as-a-Service (MAAS) is an automation software to deploy bare-metal data centers in a similar fashion as virtual machines.

Managed Control Plane

The resources used by Mirantis to manage the OpsCare deployments that are not available to customers and include the production Control Plane, StackLight, DriveTrain, and any staging environment used by OpsCare.

Management plane

A term that describes all services within StackLight and DriveTrain used for management purposes of the cloud. One Management Plane may drive multiple MCP clusters.

Mirantis Cloud Platform (MCP)

Mirantis Cloud Platform, or MCP, is a software platform that combines software components and reference architectures that enable software developers and DevOps engineers to deploy, configure, and manage cloud environments, software-defined networking, software-defined storage solutions, and other components of a private cloud.

MCP deployment architecture

MCP deployment architecture is a description of the configuration of a cloud, software defined network, or any other technology that MCP deploys. It describes how MCP deploys different components of the cloud infrastructure to meet user requirements.

MCP cluster

An MCP cluster, is a discrete, deployed unit consisting of one or more bare metal nodes with required software components that are provisioned and managed by MCP. An MCP cluster may be a Kubernetes cluster or an OpenStack environment.

MCP components

MCP components include the underlying software components that provision the cloud infrastructure of your choice. The components include cloud platform options, such as OpenStack and Kubernetes; storage options, such as Ceph; and networking options, such as Calico and OpenContrail.

MCP Registry

The MCP Registry is a Mirantis repository that provides artifacts for the CI/CD pipeline including Docker images, Python packages, binary files, and so on. The MCP Registry supports artifacts versioning for different interfaces such as Docker and packages repository and ensures seamless delivery of the requested software bits to staging and production MCP environments.


The Multi-Chassis Link Aggregation Group, or MC-LAG, or MLAG, is a network aggregation group designed to increase network bandwidth and provide redundancy in case of a failure on a chassis.


MPLS over GRE is a network technology that enables transferring of Multiprotocol Label Switching (MPLS) packets over a network that does not support MPLS by using generic routing encapsulation.


MPLS over UDP is a type of network encapsulation that enables transfer of MPLS packets over an IP fabric. MPLS over UDP supports Layer 2 and Layer 3 overlays.


Multiprotocol Label Switching (MPLS) is a technique in high-speed networking environments that accelerates network traffic by allowing network packets to be transferred through the switching layer.


A multi-cloud environment refers to a collection of clouds that do not share any resources except, optionally, a common Identity back end.


A multi-region refers to the concept of shared cloud resources across multiple regions, where the resources can be any of the following: identity, storage, networking, orchestration. Replication of metadata and/or similar configuration across regions will result in a multi-region as well. Multiple clouds that, for example, only share an Identity back end, such as LDAP, but do not share any other configuration and clouds are completely different, are not a multi-region, but a multi-cloud.


MySQL is a relational database that is most frequently used in OpenStack deployments.
