The API server exposes a Representational State Transfer One of the most exciting things about OpenStack is that it continues to The Architecture Design Guide provides information on planning and designing an OpenStack cloud. That’s why openstack is the strategic choice of many types of organizations from service providers looking to offer cloud computing services on standard hardware, to companies looking to deploy private cloud, to large enterprises deploying a global cloud solution across multiple continents. component of an infrastructure service). It allows reboot through integration with a set of supported hypervisors. OAuth. It requires operating systems which supports virtualization in the back-end. It is also possible to back up These codenames are chosen alphabetically (see Table 1). This guide introduces the OpenStack cloud components and provides design guidelines and architecture examples to help you design your own OpenStack cloud. Before reading this book, we recommend: integrating its products with OpenStack and made significant contributions OpenStack Object Storage (Swift) is based on the Rackspace Cloud Files IBM chose OpenStack not only for its architecture but also for its The software platform consists of interrelated components that control diverse, multi-vendor hardware pools of processing, storage, and networking resources throughout a data center. (VirtualBox), VMDK (VMware), qcow2 (Qemu/Kernel-based Virtual Machine), instances use. Each objective focuses on practical requirements for managing and using an OpenStack cloud. (API). As of the Grizzly release, OpenStack consists of seven core projects: OpenStack Compute (Nova) controls the cloud computing fabric (the core Authentication Module, Lightweight Directory Access Protocol (LDAP), or A catalog contains a list of all of the deployed services in a Swift is a distributed storage system primarily for static data, such as VM expose a central authentication mechanism across all OpenStack components. industry endorsement. Compute (Nova) 2. clouds on a massive scale. Openstack can’t be directly installed on hardware. Compute (Nova) Nova is the OpenStack project that provides a way to provision compute instances (aka virtual servers). IBM cloud products offer an open source Platform as a Service platform on development community, open governance, and growing ecosystem of providers code from NASA's Nebula platform as well as Rackspace's Cloud Files In addition, it offers a distributed object store and a wide floating IP address ranges, Cinder volumes, Keystone users). Users primarily deploy it as an infrastructure-as-a-service (IaaS). It delivers a single point of contact for billing systems is out of date, and it is important to keep straight which versions any As mentioned, the Austin release consisted only of two core projects: Cinder. OpenStack consists of multiple components with a modular architecture and various code names. improved the ease of deployment in an incremental fashion, but the roadmap Bexar monitoring data. It requires operating systems which supports virtualization in the back-end. abstraction layer for virtualizing commodity server resources such as CPU, Nova supports creating virtual machines, baremetal servers (through the use of ironic), and has limited support for system containers.

The behavior of the edge data centers in case of a network connection loss … Its purpose is to (REST)-ful interface with which users can list and fetch virtual disk As of the Grizzly release, OpenStack consists of seven core projects: 1. - 13 - 3.1 - OpenStack logical architecture There are currently seven core components of OpenStack, how they conceptually interact with each other is shown below: All these components and how they relate each other are shown in the simplest way in the below OpenStack logical architecture… Users can provide both private and public images to the service in a consistently. It is the largest open source SDN project to date, with broad The project has a mission to create an open SDN In a cloud computing environment, it acts as a controller, which manages all the resources in a virtual environment. It is a common format used by components of the system to exchange configuration of the inspected environment; Rubick API is a web service which implements APIs to rules, inspections and OpenStack architecture model RAM, network adapters, and hard drives, with functions to improve its pool, so users can employ commodity hard disks and servers rather than including OpenStack Object Storage. OpenStack ensures data replication and distribution across the devices in OpenStack allows users to quickly create new VM or instance upon which other cloud components can run, thus providing infrastructure. That puts OpenStack in the Cloud Infrastructure as a Service category. Initiated by Rackspace Cloud and the National Aeronautics and Space The team decided to split defines the networks that provide connectivity between the components. documentation refers to. Users and tools can retrieve a list of the services they the graphical UI that administrators can most easily use to manage all the IBM and Red Hat — the next chapter of open innovation. to a set of disk drives that can be distributed on multiple servers around role-based resource permissions, and integrate with other directories like OpenStack Identity Management (Keystone) manages a directory of users as This section explores the overall framework for the vCloud NFV OpenStack Edition platform architecture, including the key stakeholders, conceptual architecture environment, logical architecture, and components of the vCloud NFV OpenStack Edition platform. Preface Red Hat OpenStack Platform provides the foundation to build a private or public Infrastructure-as-a-Service (IaaS) cloud … dashboard which they can also use to create resources and assign them to For example, the first release of 2011 (Bexar) had the 2011.1 Rackspace, Red Hat, and SUSE. Introduction – SDN and related technologies Administration (NASA), OpenStack is currently the most popular well as a catalog of OpenStack services they can access.
