OpenStack is an open source cloud operating system that controls large pools of compute, storage, and networking resources. It was originally founded in 2010 as a pilot project between NASA and Rackspace to provide a cloud computing platform using standard hardware. OpenStack provides comprehensive cloud services through a collection of interoperable components, including compute (Nova), object storage (Swift), identity (Keystone), block storage (Cinder), networking (Neutron), and image service (Glance). Optional components offer additional services such as orchestration (Heat), databases (Trove), telemetry (Ceilometer), and more.

2. History
• OpenStack was a pilot project launched by
Backspace and NASA which was founded in July
2010.
• The purpose behind the projects was to provide
open source software that enables any
organization to create and offer cloud computing
services running on standard hardware.

3. Overview
• OpenStack is a cloud operating system that
controls large pools of compute, storage, and
networking resources throughout a data center.
• OpenStack is a collection of open source
software that allows us to perform certain
functions on the cloud.

5. What OpenStack is
• A group of open source projects aimed at
providing comprehensive cloud services.
• All projects communicate with public APIs.

6. OpenStack Components
• Core Services
• NOVA (Compute)
• SWIFT (Object Storage)
• KEYSTONE (Identity)
• CINDER (Block Storage)
• NEUTRON (Networking)
• GLANCE (Image Service)

7. OpenStack Components
• Optional Services
• HORIZON (Dashboard)
• TROVE (Database)
• CEILOMETER (Telemetry)
• SAHARA (Elastic Map Reduce)
• HEAT (Orchestration)
• IRONIC (Bare-Metal Provisioning)
• DESIGNATE (DNS service)
• BARBICAN (Key Management)
• ZAQAR (Messaging Service)

10. KEYSTONE
• KEYSTONE provides authentication,
authorization and service discovery mechanisms
via HTTP primarily for use for projects in
OpenStack family.

12. NOVA
• NOVA provides a cloud computing fabric
controller, supporting a wide variety of
virtualization technologies, including KVM, Xen,
LXC, VMware, and more.
• In addition to its native API, it
includes compatibility with the company
encountered Amazon EC2 and S3 APIs.

13. NOVA
• Filtering

• Weight

15. CINDER
• CINDER provides services and libraries for on
demand, self-service access to Block Storage
resources. Provide Software Defined Block
Storage via abstraction and automation on top of
various traditional backend block storage
devices.

17. SWIFT
• SWIFT is a distributed object storage system
designed to scale from a single machine to
thousands of servers.
• SWIFT is optimized for multi-tenancy and high
concurrency, and ideal for backups, web and
mobile content, and any other unstructured data
that can grow without bound.

19. GLANCE
• GLANCE provides a service where users can
upload and discover data assets that are meant
to be used with other services. This currently
includes images and metadata definitions.

21. HEAT
• HEAT is to create a human- and machine-
accessible service for managing the entire
lifecycle of infrastructure and applications within
OpenStack clouds.
• HEAT provides both an OpenStack-native ReST
API and a CloudFormation-compatible Query
API.

23. CEILOMETER
• CEILOMETER collects measurements of
utilization of physical and virtual resources
comprising deployed clouds, persist these data
for subsequent retrieval and analysis, and trigger
actions when defined criteria are met.
