OpenStack is an open-source cloud computing platform that provides common services for both public and private clouds. It was launched in 2010 by Rackspace and NASA as a joint project. OpenStack provides APIs and tools to provision resources like compute, storage, and networking. It allows building clouds on top of heterogeneous data center hardware. Customers choose OpenStack because it is open source, low cost, customizable, has community support, and is compatible with AWS APIs. Major companies like BMW, Disney, and Walmart use OpenStack in production environments.

Introduction to open stack

- 3. Cloud computing Cloud computing is a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications. In cloud computing, the word cloud (also phrased as "the cloud") is used as a metaphor for "the Internet," so the phrase cloud computing means "a type of Internet-based computing," where different services— such as servers, storage and applications — are delivered to an organization's computers and devices through the Internet.
- 4. Types of Cloud computing Deployment based Model 1. Public Cloud (http://www.hwclouds.com/en-us/) 2. Private Cloud (Huawei workspace Fusion Access) 3. Hybrid Cloud = Public + Private Service based Model 1. Infrastructure as a Service (IaaS) 2. Platform as a Service (PaaS) 3. Software as a Service (SaaS)

- 6. Cloud Data-center OpenStack is an distributed cloud operating system provides an platform for setting up public or private cloud on top of heterogeneous data-center. For operator, It provides set of configurable device- drivers/plug-ins to consume the required hardware-devices and software-defined-devices from cloud data-center regions. And for consumers, it provides required RESTful API, CLI to provision and manage their cloud resources such as instances, storage volumes, networks, etc. programmatically. OpenStack OpenStack is Open-source, Openly-designed, Openly-developed by Open-community
- 7. OpenStack • RESTful API • CLI • Python sdk
- 8. From Github to Cloud Datacenter Data-center Compute Network Storage
- 9. As of latest release 6.0.0
- 10. Why Customer choose OpenStack 1. Open Standard – No vendor lock-in 2. Cost – Apache 2 License – Its free 3. Control - Customize to your needs – leverage existing infra 4. Support - Larger community support 5. Compatibility with AWS API – Flexibility – Easy to migrate

Editor's Notes
- #9: Assume all the cloud nodes (controller, Storage, compute and network) are up and running , Data center also in place Now Openstack github provides the complete source code Configuration guide helps operator to configure OpenStack Installers There are many Openstack Distros available in the market and it does provide installers for devices It packs the source code from github and covert them as installable packages It read thru the configuration guide and make configuration automation All these 3 together forms the installer During the installation, respective services got installed into appropriate servers Openststack distro installs required devices in the datacenter It configures the intalled devices in respective service nodes Namos is brought up here to take care of configuration automation complete irrespective of the OpenStack installers
