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 7

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.
