OpenStack is a an open source cloud operating system managing compute, storage, and networking resources throughout a datacenter using APIs. Furthermore, OpenStack supports hyper-converged architecture, meaning that control, compute, network and storage services are distributed across all nodes in the cluster. The compute controller provides compute server resources and usually also contains the Compute service. OpenStack is represented by three core open source projects (as shown in Figure 2): Nova (compute), Swift (object storage), and Glance (VM repository). This slideshare explains the architecture of OpenStack. While it is an optional part of the overall compute architecture, I can’t imagine that most OpenStack Nova installation will not be using it (or a complimentary product). OpenStack Compute serves as the core of the OpenStack cloud by providing virtual machines on demand. Nova Compute receives the request, gets IP/mac info from neutron, and calls the spawn() on Huawei-FC Driver. how can I install OpenStack with two node architecture i.e. True, BUT, Nova design started off as a virtual machine scheduler, with features specific to this use case. OpenStack Compute (Nova) is one of the original components of OpenStack. I have installed All-in-one OpenStack node. Section 1.3.3, “OpenStack Image (glance)” Object Storage OpenStack Architecture: It includes several major component: Dashboard (Horizon): Users log into U I specifies V M ( Virtual Machine ) parameters (such as name , flavor , keys etc . Swift can be used as a stand-alone storage system or as part of a cloud compute … This document provides a reference architecture for users to build an OpenStack environment with Open Compute Project (OCP) hardware and the Ubuntu 14.04 LTS operating system. Openstack controls large pools of compute, storage, and networking resources, all managed through APIs or a dashboard. 4. Active Sub-teams TODO - this list can get out-of-date, need a better approach. OpenStack Compute Node. one controller and one compute? Management of Local Area Networks (Flat, Flat DHCP, VLAN DHCP and IPv6) through programmatically allocated IPs and VLANs. 6. El proyecto está gestionado por la Fundación OpenStack, una persona jurídica sin fines de lucro creada en septiembre de 2012 para promover el software OpenStack y su comunidad. Compute (Nova) I can relate the openStack Controller to the Vmware ESXI. 3. We’ll also show you how to integrate three prominent OpenStack use cases with Ceph: Cinder (block storage), Glance (images) and Nova (VM virtual disks).. Ceph provides unified scale-out storage, using commodity x86 hardware that is self-healing and intelligently anticipates failures. My understanding (after reading all the docs) is that the compute nodes run a host OS (ubuntu or other linux) and on top of that you have your hypervisor (like KVM) and then the VMs run on top of it i.e HW -> OS -> Hypervisor -> VMs . OpenStack Swift Architecture ... that model no longer works since to get throughput, scale and availability, you need to approach your storage architecture in a different way and replicate data over multiple locations. Approval of patches is still done by the nova-core team and it is beneficial to publish designs to the openstack-dev mailing list for vetting in advance. OpenStack Glance is a separate project from OpenStack Nova, but as shown above, complimentary. Beyond standard infrastructure-as-a-service functionality, additional components provide orchestration, fault management and service management amongst other services to ensure high availability of user applications. I am beginner in openStack. It is composed of recommended hardware, software architecture and the validated installation steps to help users to set up clouds from bare metal. So, whether you are choosing architectures for cloud-based web applications, eCommerce, big data, a compute starter, container optimized, or other pre-defined cloud computing systems, OpenStack offers what you need to leverage user-friendly cloud-based architecture. OpenStack has emerged as the leading open source choice of communications service providers for NFVi & VIM as part of their Network Functions Virtualization (NFV) architecture.
