Based on the cloud, HP Helion's cloud path. Let's talk about the concept of cloud platform and cloud computing. I remember that it was first proposed by Google, whose main purpose was to allow users around the world to use a simple display screen, turn on the display screen to connect to the service system built on the cloud platform by the cloud service provider through the network, select the services you need, or store your information in the cloud platform, use the same information as your
In May this year, HP announced the Helion cloud plan and plans to invest $1 billion in the next two years. Next, HP began to methodically promote the implementation of the plan. The latest news is that in July 1, Hewlett-Packard announced the establishment of a Global Helion alliance, hoping to attract independent software vendors, developers, system integrators, and value-added dealers to join in and build

This tutorial is based on the Ubuntu12.04 edition, and it will help readers build a openstack minimized installation. I am the top of the Wuyue, translation more use of transliteration method, so the individual words and the original discrepancy, please understand. I am not a major in English, I think the most important thing is to understand the technology, and not the four level and grind in the boring English-Chinese translation, so my goal is loya

OpenStack supports almost all types of cloud environments, and the p

Because I only focus on the part of openstack Object Storage, I did not write anything related to other modules (or I am relatively lazy). I may add it if necessary in the future.
The translation level is limited. If a netizen finds an error during re
OpenStack is an excellent cloud operating system, and it is wise for developers, administrators, and operators to have the skills associated with them in their virtual toolkit. Efficient cloud requires an efficient database and can accept multiple databases. But what if you want IBM? DB2 for OpenStack, what should I do? OpenStack does not support DB2 by default.
As a core tutorial for OpenStack, we have come to the final summary.
OpenStack currently has dozens of modules, this tutorial discusses the most important core modules: Keystone,nova,glance,cinder and neutron. Please look at the following figure:
This figure is truncated from https://www.openstack.org/software/project-navigator/, which is the official 6 Core Service defined by
The entire life cycle of instance from creation to deletion is managed by Nova. In the following sections, we take the different operational scenarios in the instance life cycle as an example to analyze in detail how the different Nova components work together and deepen your understanding of Nova through log analysis.Before we study Nova's operations, let's start by learning one important thing: the OpenStack logs.OpenStack's log records very detaile
