Within each data center, the racks of equipment are built to be fault tolerant on a networking, physical host servers, storage, and power level. Workloads that care about resiliency would be defined with fault domain capabilities within MuranoPL.
A federated identity is a set of technologies that enables multiple isolated identity management systems to share same user credentials. In an OpenStack deployment, a federated identity is the ability for an identity, such as user or service, to access resources across administrative domains separated by Keystone services.
The process of locking resources away from a node whose status is uncertain. Ceph supports fencing. However, you must ensure that no controllers host both the Ceph OSD and Ceph Monitor roles.
A floating IP address is an IP address, usually public, that is dynamically associated with a running virtual instance to make the VM accessible to the outside world. External ports are associated with tenant routers, not with virtual instances.
Fuel Master node is a server with the Fuel application. The Fuel Master node runs on a stand alone physical or virtual hardware. The Fuel Master node automatically discovers and assigns IP addresses to the OpenStack nodes, boots the Fuel Slave nodes over PXE, and configures initial settings. After discovering the Fuel Slave nodes, you can use the Fuel web UI and CLI to deploy and manage OpenStack environments.
A Fuel plug-in is a software module that adds additional functionality to Fuel and OpenStack environments. A Fuel plug-in may include OpenStack component implementations, such as Murano, software-defined network extensions, such as Juniper Contrail Networking, monitoring solutions, such as StackLight, and so on.
Fuel is an open source, software life cycle management application that deploys multiple OpenStack environments from a single interface and then enables you to monitor, test, and manage those environments post deployment. Fuel provides web UI, CLI, and REST APIs that facilitate deployment, management, and monitoring of your OpenStack environments. Fuel REST APIs enable you to make advanced configuration changes, as well as develop your own software components, such as drivers and plug-ins. In addition, you can leverage multiple plug-ins that extend functionality of your environments in a flexible, repeatable, and reliable manner.
