In a threenode OpenStack architecture, which services are part of the compute node? (Select 2 choices.)
- Ceilometer Agent
- Ceilometer Core
- Neutron DHCP Agent
- Neutron Server
- Nova Hypervisor
- Nova Management
- Correct
In a three-node OpenStack architecture, the Ceilometer Agent and the Nova Hypervisorservices are part of the compute node. OpenStack is an opensource cloudcomputing platform. Each OpenStack modular component is responsible for a particular function, and each component has a code name. The following list contains several of the most popular OpenStack components:
-Nova -OpenStack Compute: manages pools of computer resources
-Neutron -OpenStack Networking: manages networking and addressing
-Cinder -OpenStack Block Storage: manages blocklevel storage devices
-Glance -OpenStack Image: manages disk and server images
-Swift -OpenStack Object Storage: manages redundant storage systems
-Keystone -OpenStack Identity: is responsible for authentication
-Horizon -OpenStack Dashboard: provides a graphical user interface (GUI)
-Ceilometer -OpenStackTelemetry: provides counterbased tracking that can be used for customer usage billing
A threenode OpenStack architecture consists of the compute node, the controller node, and the network node. The compute node consists of the following services:
-Nova Hypervisor
-Kernelbased Virtual Machine (KVM) or Quick Emulator (QEMU)
-Neutron Modular Layer 2 (ML2) PlugIn
-Neutron Layer 2 Agent
-Ceilometer Agent
-The controller node consists of the following services:
-Keystone
-Glance
-Nova Management
-Neutron Server
-Neutron ML2 PlugIn
-Horizon
-Cinder
-Swift
-Ceilometer Core
The network node consists of several Neutron services:
-Neutron ML2 PlugIn
-Neutron Layer 2 Agent
-Neutron Layer 3 Agent
-Neutron Dynamic Host Configuration Protocol (DHCP) Agent
