OpenStack provides an Infrastructure-as-a-Service (IaaS) solution
|
|
through a variety of complementary services. Each service offers an
|
|
application programming interface (API) that facilitates this
|
|
integration. The following table provides a list of OpenStack services:

|
"openstack-compute-controller", "Nova", "Manages the lifecycle of
|
|
compute instances in an OpenStack environment. Responsibilities include
|
|
spawning, scheduling and decommissioning of virtual machines on demand."
|
|
"openstack-identity", "Keystone", "Provides an authentication and
|
|
authorization service for other OpenStack services. Provides a catalog
|
|
of endpoints for all OpenStack services."
|
|
"openstack-image", "Glance", "Stores and retrieves virtual machine disk
|
|
images. OpenStack Compute makes use of this during instance provisioning."
|
|
"openstack-dashboard", "Horizon", "Provides a web-based self-service portal
|
|
to interact with underlying OpenStack services."
|
|
"openstack-network", "Neutron", "Enables Network-Connectivity-as-a-Service
|
|
for some OpenStack services. Besides, it provides an API for users to define
|
|
networks and the attachments into them."
|
|
"openstack-object-storage", "Swift", "Stores and retrieves arbitrary
|
|
unstructured data objects. It is highly fault tolerant with its data
|
|
replication and scale-out architecture."
|
|
"openstack-block-storage/openstack-block-storage-controller", "Cinder", "Provides
|
|
persistent block storage to running instances."
|
|
"openstack-telemetry", "Ceilometer", "Monitors and meters the
|
|
OpenStack cloud for billing, benchmarking, scalability, and statistical
|
|
purposes."
|
|
"openstack-orchestration", "Heat", "Orchestrates multiple composite cloud
|
|
applications by using either the native Heat Orchestration Template (HOT)
|
|
template format or the AWS CloudFormation template format."
|
|
|
|
OpenStack is highly configurable to meet different needs. This guide
|
|
uses a two-node architecture.
|
|
|
|
- The controller node runs the Identity Service, Image Service, the
|
|
management portion of Compute, and the Dashboard. It also includes
|
|
supporting services, such as an SQL database and message queue.
|
|
Optionally, the controller node runs management portions of Block
|
|
Storage services.
|
|
- The compute node runs the hypervisor portion of Compute that operates
|
|
project virtual machines or instances. By default, Compute uses KVM
|
|
as the hypervisor. Compute also provisions project networks and
|
|
provides firewalling (security groups) services. You can run more
|
|
than one compute node.
|
|
- (Optional) Block Storage node contains the disks that the Block
|
|
Storage service provisions for instances. You can deploy more than
|
|
one block storage node.
|
|
- (Optional) Object Storage node contain the disks that the Object
|
|
Storage service uses for storing accounts, containers, and objects.
|
|
This service requires two nodes. Each node requires a minimum of one
|
|
network interface. You can deploy more than two object storage nodes.
|
|
- The self-service networks option augments the provider networks option
|
|
with layer-3 (routing) services that enable self-service networks
|
|
using overlay segmentation methods. Additionally, this option provides
|
|
the foundation for advanced services such as LBaaS and FWaaS.
