WHAT IS OPENSTACK
• OpenStack is a cloud operating system that controls large pools of compute,
storage, and networking resources throughout a datacenter with a dashboard.
COMPONENTS
Basic building Components are
• Compute (Nova)
• Object Storage (Swift)
• Block Storage (Cinder)
• Networking (Neutron)
• Dashboard (Horizon)
COMPONENTS(CONT.)
Apart from above there are some Shared Components
a. Identity Service (Keystone)
b. Image Service (Glance)
c. Telemetry (Ceilometer)
d. Orchestration (Heat)
COMPUTE (NOVA)
• Provision
and manages large networks of virtual machines
COMPUTE (NOVA )
•Base image state with no running
instances
•
Instance creation from image and run
time state

STORAGE
Object Storage:
Object Storage provides a fully distributed, API-accessible storage platform that can
be integrated directly into applications or used for backup, archiving and data
retention.
Block Storage:
Block Storage allows block of storages to be exposed and connected to compute
instances for expanded storage, better performance and integration with enterprise
storage platforms
NETWORKING(NEURON)
• Neutron is an OpenStack project to provide "networking as a service"
between interface devices.
DASHBOARD (HORIZON)
• Dashboard provides a web based user interface to OpenStack services
including Nova, Swift, Keystone, etc.
• The OpenStack dashboard provides administrators and users a graphical
interface to access, provision and automate cloud-based resources.
SAMPLE DASHBOARD
IDENTITY SERVICE (KEYSTONE)
• Keystone is the identity service used by OpenStack for authentication (authN)
and high-level authorization (authZ).
•
It currently supports token-based authN and user-service authorization.
IMAGE SERVICE (GLANCE)
• The OpenStack Image Service provides discovery, registration and delivery
services for disk and server images
TELEMETRY (CEILOMETER)
• The OpenStack Telemetry service aggregates usage and performance data
across the services deployed in an OpenStack cloud.
ORCHESTRATION (HEAT)
• OpenStack Heat program is to create a human- and machine-accessible
service for managing the entire lifecycle of infrastructure and applications
within OpenStack clouds.

USE CASES OF OPENSTACK:
• IaaS compute platform
• Processing big data with tools like Hadoop
• Scaling compute up and down to meet demand for web resources and
applications
• High-performance computing (HPC) environments processing diverse and
intensive workloads
• Different users of OpenStack are AT&T, HP cloud services, PayPal, Rackspace,
Sony online gaming systems, Yahoo, Wikimedia labs, Intel, NASA etc...
