Openstack

STUDY ON OPENSTACK BY JAI KRISHNA

LIST OF COMPONENTS • Introduction • Components • Architecture • Where it is used

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.
