OpenStack Nova - Developer Introduction 1. OpenStack is a popular open source cloud computing project promoted by IBM and other industry leaders. Now that we’ve looked at a proposed conceptual architecture, let’s see how OpenStack Nova is logically architected. The main components of Nova are nova-api, rabbitmq-server, nova-compute, nova-network, nova-volume and nova-scheduler. OpenStack training April, 2014 Belmiro Moreira belmiro.moreira@cern.ch @belmiromoreira neutron-dhcp-agent Agent that provides DHCP services to tenant networks. trove-api ppk@idre.ucl.a.edu.. Essex.DistribuKon. OpenStack Architecture. Within the OpenStack architecture most of the focus is in the Nova* component, and we briefly look at how Glance might play a role in simplifying future configurations. Maybe OpenStack if. 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. Nova is comprised of multiple server processes, each performing different functions. Compute nova Manages and provisions virtual machines running on hypervisor nodes. All services provided by Nova are accessible via an API that is compatible with the AWS EC2. Before we dive into the conceptual and logic architecture, let’s take a second to explain the OpenStack project: Agenda• Overview of Cloud computing, Service model and deployment.• What is OpenStack.• Who are involved.• Projects under OpenStack.OpenStack Releases•• Overview of OpenStack architecture.• How to contribute in OpenStack.• Q&A. OpenStack is an open source software that allows for the deployment and management of a cloud infrastructure as a service (IaaS) platform. Then, you will focus on installing, configuring, and troubleshooting different architectures such as Keystone, Horizon, Nova, Neutron, Cinder, Swift, and Glance. It is basically a virtualization hypervisor. non-x86 cpu architecture: because DMI data is buggy on some arches; Is OpenStack if x86 architecture and ANY of the following /proc/1/environ: Nova-lxd contains product_name=OpenStack Nova; DMI product_name: Either Openstack Nova or OpenStack Compute; DMI chassis_asset_tag is OpenTelekomCloud, SAP CCloud VM, OpenStack Nova (since 19.2) or OpenStack … OpenStack/Nova Infrastructure.as.aService. Trove is designed to support a single-tenant database within a Nova instance. Ubuntu.12.04.LTS. Flavors, Filter Attributes, and Extra Specifications ( IaaS). OpenStack is an open source platform, which offers powerful virtual servers and required services for cloud computing. It fulfills two main requirements of the cloud: massive scalability and simplicity of implementation. Compute (Nova) Nova is the OpenStack project that provides a way to provision compute instances (aka virtual servers). Since OpenStack is a fairly broad topic, I’ll break my thoughts into several posts. In this architecture type, OpenStack integrates with Hadoop to manage the Hadoop cluster with Ceph as the storage backend. An overview of the OpenStack architecture can be seen in Figure 2. OpenStack : OpenStack is a cloud operating sysetem that controls large pools of compute , storage and networking resources throughout a datacenter. Section 1.3.1, “OpenStack Compute (nova)” Image glance Registry service that you use to store resources such as virtual machine images and volume snapshots. OpenStack 101 with Joshua McKenty from Piston Cloud Computing. 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. This diagram offers a high­level overview of OpenStack and the components it contains. In this post, which is part of our series on OpenStack, we will start to investigate OpenStack Neutron - the OpenStack component which provides virtual networking services. nova-network, nova-scheduler, etc. Nova System Architecture¶. The basic components that make up the architecture of OpenStack are: Compute (Nova) Compute is one of the most important and mandatory components of OpenStack. OpenStack Architecture. OpenStack’s service architecture is made up of services that all talk with each other to get things done. As can be seen, the client interacts with the Nova API It is mostly deployed as Infrastructure-as-a-service (IaaS), which aims to… Network types and some terms Before getting into the actual Neutron architecture, let us try to understand how Neutron provides virtual networking capabilities to compute instances. 3. Openstack controls large pools of compute, storage, and networking resources, all managed through APIs or a dashboard. Other articles in the series will detail various OpenStack components. OpenStack has a modular architecture with various code names for its components. Prakashan.Korambath. For more information about OpenStack you can go here. This complicated diagram can be summed up in three sentences: End users who want to use Nova to create compute instances call nova-api with OpenStack API or EC2 API requests. This slideshare explains the architecture of OpenStack. OpenStack Reference Architecture For 100, 300 and 500 Nodes¶. In a cloud computing environment, it acts as a controller, which manages all the resources in a virtual environment. OpenStack is the open source cloud platform that enables Infrastructure as a Service (IaaS). More detailed Architecture info can be found here.
