openstack introduction

OpenStack Storage Module-cinderSome of the basics of OpenStack are described in the first two documents, but they are not included in the enclosure. This article mainly introduces the storage module cinder of OpenStack.Storage is divided into three main types: Block storage: Hard drives, storage devices, magnetic consolidation columns, etc. File storage: Storage that is used primarily for file

Preface: The entire openstack consists of control nodes, computing nodes, network nodes, and storage nodes. The basic management services of control nodes include five services: Keystone, glance, Nova, neutron, and horizon. This article will deploy the galnce component.Glance: The image Management Service manages images that can be provided during Virtual Machine deployment, including image import, format, and corresponding templates.

CEO of RedHat on VMware, OpenStack, and CentOS RedHat has completed an acquisition to build an open-source stack that leads the hybrid data center, and its main competitor is VMware. The duel between RedHat and VMware remains to be observed, but Jim whitehust, CEO of RedHat, believes that open source will ultimately define the future of enterprise IT architecture. I met whitehirst and talked to him about the overall planning of cloud, open source, and

Reprint: http://www.ibm.com/developerworks/cn/cloud/library/cl-contributecode-openstack/ With the support of OpenStack (open source cloud software), more and more individuals and businesses want to contribute to the OpenStack community. Bug reports, blueprint agreements (Blueprint engagement), and code reviews are just a few ways to contribute. This article pro

In the past ten years, RHEL has made RedHat the dominant position in the enterprise-level Linux market. Ten years later, RedHat hopes to build an IaaS solution on OpenStack to realize the company's leapfrog development. RedHat is now focusing on cloud computing and plans to use it as the main driving force to support its business development in the next decade. Only this time, the most prominent focus is that Redhat has successfully invested money in

OpenStack provides a wide range of network configuration environments. This article describes how to design a cloud system to consider and design network requirements. If this is the first time you deploy a cloud system in your organization, please contact your network O M team after reading this section to learn about the current network conditions. The network used by the cloud system is different from the network deployment method used by the comm

This article explains that OpenStack uses iptables, chains, and rules to handle networking, which is very similar to other systems. But first, let's look at the structure of Iptables as a prelude to the use of technology in this article. The structure of the iptable Iptable is a user-space application that allows system administrators to configure tables provided by the Linux kernel firewall, iptable specifically IPV4 networks.
