It was integrated in the Essex release and this service was introduced during the fifth OpenStack release.
Keystone is the authentication and authorization component built into your OpenStack cloud. Its key role is to handle creation, registry, and management of users, tenants, and all the other OpenStack services. Keystone is the first component to be installed when starting an OpenStack cloud.
It has the capability to connect to external directory services, such as LDAP. Another key feature of Keystone is that it is built based on role-based access controls RBAC , thus allowing cloud operators to provide distinct role-based access to individual service features to the cloud consumers.
It was also integrated in the Essex release and this service is the second service to be introduced in the fifth OpenStack release. Horizon provides cloud operators and consumers with a web based GUI to control their compute, storage, and network resources. The OpenStack dashboard runs on top of Apache and the Django REST framework; thus, making it very easy to integrate into and extend to meet your personal use case. The basic principle behind Horizon was to be able to provide cloud operators with a quick and overall view of the state of their cloud and cloud consumers a self-service provisioning portal to the cloud resources designated to them.
It was integrated in the Folsom release and this service is probably the second most powerful component within your OpenStack cloud next to Nova. This quote was taken directly from the OpenStack Networking documentation, as it best reflects exactly the purpose behind Neutron.
Neutron is responsible to create your virtual networks with your OpenStack cloud. This will entail the creation of virtual networks, routers, subnets, firewalls, load balancers, and similar network functions. The various vendor specific plugins and adapters have been created to work in line with Neutron.
This service adds to the self-service aspect of OpenStack; thus, removing the network aspect from being a roadblock to consume your cloud.
With Neutron being one of the most advanced and powerful components within OpenStack, a whole book was dedicated to it. It was also integrated in the Folsom release, Cinder is the component that provides block storage as a service to your OpenStack cloud by leveraging local disks or attached storage devices. This translates into persistent block level storage volumes available to your instances. One of the highly notable features of Cinder is its ability to connect to multiple types of backend shared storage platforms at the same time.
This capability spectrum spans all the way down to being able to leverage simple Linux server storage as well. As an added bonus, Quality of Service QoS roles can be applied to different types of backends; thus, extending the ability to use the block storage devices to meet various application requirements. It was integrated in the Havana release and this was one of the two services to be introduced in the eighth OpenStack release.
Heat provides the orchestration capability over your OpenStack cloud resource. It is described as a main-line project part of the OpenStack orchestration program. This infers the additional automation functionality that is in the pipeline for OpenStack. The built-in orchestration engine is used to automate provisioning of applications and its components, known as stack.
A stack might include instances, networks, subnets, routers, ports, router interfaces, security groups, security group rules, auto scaling rules, and so on. Heat utilizes templates to define a stack and is written in a standard markup format, YAML.
It was also integrated in the Havana release and this is the second of the two services introduced in the eighth OpenStack release. Ceilometer collects the cloud usage and performance statistics together into one centralized data store. This capability becomes a key component to a cloud operator as it gives clear metrics into the overall cloud, which can be used to make scaling decisions.
You have the option of choosing the data store backend to Ceilometer. It was integrated in the Icehouse release, Trove is the component that provides database as a service to your OpenStack cloud. This capability includes providing scalable and reliable relational and non-relational database engines. The goal behind this service was to remove the burden of needing to understand database installation and administration.
With Trove, the cloud consumers can provision database instances just by leveraging the services API. Trove supports multiple single-tenant databases within a Nova instance. It was integrated in the Juno release, Sahara is the component that provides data processing as a service to your OpenStack cloud.
This capability includes the ability to provision an application cluster tuned to handle large amounts of analytical data. This service will also aid the cloud consumer in being able to abstract the complication of installing and maintaining this type of cluster. It was integrated in the Kilo release and this service has been one of the most anxiously awaited components of the OpenStack project.
Ironic provides the capability to provision physical bare metal servers from within your OpenStack cloud. It is commonly known as a bare metal hypervisor API and leverages a set of plugins to enable interaction with the bare metal servers.
It is the newest service to be introduced to the OpenStack family and is still under development. It is similar to any traditional application, there are dependent core components that are pivotal to the functionality but not necessarily the application itself.
In the case of the base OpenStack architecture, there are two core components that will be considered as the core or backbone of the cloud.
