What is Openstack ?

OpenStack is a large Cloud ecosystem that permit controls pools of storage, compute, and networking resources throughout a data-center.

This is managed with a dashboard and gives to the administrator the control to provision resources through a web interface (horizon)

OpenStack is managed by the OpenStack Foundation, a non-profit that oversees both development and community-building around the project.

Introduction to OpenStack

OpenStack lets users deploy virtual machines and other instances that handle different tasks for managing a cloud environment on the fly. It makes horizontal scaling easy, which means that tasks that benefit from running concurrently can easily serve more or fewer users on the fly by just spinning up more instances. For example, a mobile application that needs to communicate with a remote server might be able to divide the work of communicating with each user across many different instances, all communicating with one another but scaling quickly and easily as the application gains more users.

And most importantly, OpenStack is open source software, which means that anyone who chooses to can access the source code, make any changes or modifications they need, and freely share these changes back out to the community at large. It also means that OpenStack has the benefit of thousands of developers all over the world working in tandem to develop the strongest, most robust, and most secure product that they can.

Openstack definition:

Compute: Nova

Networking: Neutron

Neutron is an OpenStack project to provide “networking as a service” between interface devices (e.g., vNICs) managed by other Openstack services (e.g., nova).

Starting in the Folsom release, Neutron is a core and supported part of the OpenStack platform (for Essex, we were an “incubated” project, which means use is suggested only for those who really know what they’re doing with Neutron).

Object storage: Swift

Block Storage: Cinder

Identity: Keystone

Image Service: Glance

Dashboard: Horizon

Telemetry “metering”: Ceilometer

Project Mission

To reliably collect data on the utilization of the physical and virtual resources comprising deployed clouds, persist these data for subsequent retrieval and analysis, and trigger actions when defined criteria are met.


The telemetry requirements of an OpenStack environment are vast and varied, they include use cases such as metering, monitoring, and alarming to name a few. The scope of these uses cases are diverse and beyond the scope of a single project and team. Currently, the telemetry project provides a set of functionality split across multiple projects; each project designed to provide a discrete service in the telemetry space.

Database: Trove

Mission Statement
The OpenStack Open Source Database as a Service Mission: To provide scalable and reliable Cloud Database as a Service provisioning functionality for both relational and non-relational database engines, and to continue to improve its fully-featured and extensible open source framework.

Trove is Database as a Service for OpenStack. It’s designed to run entirely on OpenStack, with the goal of allowing users to quickly and easily utilize the features of a relational or non-relational database without the burden of handling complex administrative tasks. Cloud users and database administrators can provision and manage multiple database instances as needed. Initially, the service will focus on providing resource isolation at high performance while automating complex administrative tasks including deployment, configuration, patching, backups, restores, and monitoring.

Data Processing: Sahara

The sahara project aims to provide users with a simple means to provision data processing frameworks (such as Hadoop, Spark and Storm) on OpenStack. This is accomplished by specifying configuration parameters such as the framework version, cluster topology, node hardware details and more.
