Questions & Answers

Q: What is OpenStack?

OpenStack is an open-source cloud software that controls large pools of computing, storage, and network resources in a data center while managing through a dashboard.

Q: When was OpenStack initially released?

OpenStack was initially released in 2010 by NASA and Rackspace.

Q: How has OpenStack grown since its initial release?

OpenStack has grown into a large community with over 9000 contributors and nearly 500 companies involved in its development and usage.

Q: What are the key components of OpenStack?

The key components of OpenStack include compute, storage, networking, dashboard, Glance (image services), Swift (object storage), Keystone (identity service), Neutron (networking), Cinder (block storage), Ceilometer (telemetry), and Heat (orchestration).

Q: What is the role of the OpenStack dashboard?

The OpenStack dashboard, also known as Horizon, acts as the graphical interface that allows users to automate cloud-based resources, access services, and manage tools for OpenStack.

Q: How does OpenStack ensure secure identity management?

OpenStack uses Keystone, an identity service component, to provide a central list of users mapped against OpenStack services. It supports various forms of authentication and integrates with existing back-end services such as LDAP.

Q: What is the purpose of the OpenStack Neutron component?

Neutron is responsible for networking in OpenStack. It allows users to create their own networks and connect devices and servers to one or more networks, providing self-service network configuration.

Q: What does the Cinder component of OpenStack provide?

Cinder, the block storage component, delivers determined block-level storage devices for applications with OpenStack compute instances. Cloud users can manage their storage needs by integrating block storage volumes with the dashboard and Nova.
