First understand its overall structure, and figure out why to use such a framework; Then understand the various components in the architecture,
application development platform Lab Test Platform Use cases that use scale-out effects that are better than vertical scaling are the ideal object for general-purpose cloud architectures.A general-purpose cloud environment is potentially useful and functional, rather than customized for a given user. The general purpose architecture is designed to meet 80% of potentially available cases. The infrastructure itself is a designated case, intend

Southbound: clarify the virtual machine lifecycle The underlying functions, how to construct xml files, and how to connect libvirt Differences between KVM and XEN Components: abandon devstack and manually create an OpenStack
This series of articles focuses on learning and researching OpenStack Swift, including environment building, principles, architecture, monitoring, and performance.(1) OpenStack + Three-node Swift cluster + HAProxy + UCARP installation and configuration(2) principle, architecture and performance(3) Monitoring1.
The full text includes three parts: The first part Part II Part III In the first part of this series, I covered six requirements for enterprise-level OpenStack. Now, I'll focus on the next two main requirements: open architecture and hybrid cloud compatibility. Let's get started right away.Demand 3-open architecture and reduce vendor lock-in
Before the Spring festival in the latest version of the OpenStack Liberty Network, a better introduction to the Liberty Network implementation and some new technology articles. After careful study decided to write the experience after the study.This series of articles is divided into 7 sections, each of which describes:1.Liberty Network Overview2. Network Architecture3.Neutron Configuration4. Network creation5. Add routes, networks, and subnets6. Star

This interaction typically manifests itself as a series of messages between different objects.Component diagrams help visualize the high-level structure of a software system.A class diagram describes an object in an application system. This description does not refer to any particular implementation of the system itself.A hierarchy diagram is used to describe the logi
This blog post mainly builds the keystone component in the openstack architecture, and then it will successively manage glance, Nova, neutron, Horizon, cinder, and virtual machines in openstack. Before deploying the experiment, you must first learn about openstack!What is openstack
on the Advanced blade server that connects the fibre storage network. Even Microsoft Exchange began recommending the evolution from RAID to JBOD, which instead relied on the application layer for fault tolerance.Let's take a closer look at the three requirements of enterprise-class OpenStack.Scalability and Performance (Scalability performance)Scalability is a feature of the system's ability to meet growing system size and load requirements. Performance is a dimension of the throughput of a si

segments, we need router to connect them together. To analyze this setup, we create another network (NET2) and configure a 20.20.20.0/24 subnet. After this network is created, we launch a virtual machine for Oracle Linux and connect to Net2. is the network topology diagram seen from the Openstackgui:For further exploration, we will see another namespace on the OpenStack network node, the namespace used to
OpenStack Swift source code Introduction: overall business architecture and Proxy process The source code analysis of OpenStack has been widely used on the Internet, and the interpretation of each part is also very detailed. Here, I will record some key points of the Swift source code I have read Based on my own understanding, hoping to help the students who nee

users. It is believed that with the application architecture of the Internet technology being accepted by the traditional industry, object storage and Swift will be more and more widely concerned.From the OpenStack kilo version of the data, the swift community presents a diversity of features and is developing healthily.This article and the next two articles in this series will introduce the
