本文是对《CY12-Q3 OpenStack, OpenNebula,Eucalyptus,CloudStack社区活跃度比较》一文的补充和更新。对本文内容感兴趣的读者,可以通过电子邮件或者新浪微博(@qyjohn_)与我联系。

本文同时发布了一个英文版本,可以参见CY12-Q4 Community Analysis — OpenStack vs OpenNebula vs Eucalyptus vs CloudStack这个帖子。

需要说明的是,这个社区活跃度比较项目起源于CY11-Q4,此篇报告是到目前为止已经发布的第五个季度性的报告。尽管作者于2012年10月成为Eucalyptus公司的员工,但是本文中所表达之观点完全是作者本人的观点,而非作者所在公司的观点。还需要指出的是,作者所在的公司完全同意作者以独立的视角继续此项目。

Just before the holidays, Amazon released awscli, a new command-line interface for managing AWS resources.  The code is based on botocore, the core python library for the next major version of boto.  I took awscli for a spin to see if it worked with the Eucalyptus Community Cloud, and as is often the case, the answer was ... almost.

First, it's useful to understand the fundamental problems that awscli was trying to address.  The most obvious is profiles.  Cloud users deal with...

I recently blogged about the importance of Maintainability for on-premise Clouds. Within the lists of steps to a successful on-premise Cloud deployment identified in the blog, Eucalyptus as IaaS software is heavily involved with the Deploy and Maintain part. 

Deploy I already  mentioned the work done to make Eucalyptus installation easy peasy, so let me summarize them here. Eucalyptus is packaged for the main Linux distritributions, so the installation is as easy as configuring the...

Happy New Year! I want to thank everyone who promoted, followed, commented and inspired my blog entries in 2012. I look forward to providing more material in 2013. The WordPress.com stats helper monkeys prepared a 2012 annual report for this blog. Here’s an excerpt: 600 people reached the top of Mt. Everest in 2012. This [...]

Preface A few weeks back, I was doing some testing with the guys from AppScale to get an Eucalyptus Machine Image (EMI) to run on Eucalyptus.  The image that was provided to me was an EBS-backed Amazon Machine Image (AMI), using a published EC2 Lucid Ubuntu Cloud image.  This blog entry describes the procedure to convert [...]

前段时间陆续发布了一些对公有云服务性能评测的数据。经常有同行问我怎么样去做这些性能评测。其实这些性能评测都很简单,任何一个具备Linux基础知识的工程师都可以完成。我们通常使用UnixBench来评估虚拟机CPU性能,mbw来评估内存性能,iozone来评估文件IO性能,iperf来评估网络性能,pgbench来评估数据库性能。在这里我将我自己做性能测试的过程整理一下,供各位同行参考。

(0)安装必要的软件

假定VM的操作系统是Ubuntu,可以按照如下步骤安装必要的软件:

sudo apt-get install python-software-properties
sudo add-apt-repository ppa:pitti/postgresql
sudo apt-get update
apt-get install libx11-dev libgl1-mesa-dev libxext-dev perl perl-modules make gcc nfs-common postgresql-...

Reblogged from Technological Musings: The latest release of Eucalyptus has introduced a new user user console. The user console is written in Python and is using the logging module that can easily be setup to work with rsyslog. It even uses it out the box! Unfortunately, the user console is sending a lot of verbose [...]

The latest release of Eucalyptus has introduced a new user user console. The user console is written in Python and is using the logging module that can easily be setup to work with rsyslog. It even uses it out the box! Unfortunately, the user console is sending a lot of verbose and useless information into /var/messages which I don’t like. /var/log/messages is the main log for my system so I’d like to make sure that I can find important messages easily. The Eucalyptus user console also uses...

On December 18, 2012, Eucalyptus  v3.2 was released.  One of the main focuses on this release was to harden the High Availability design of Eucalyptus.   I recently have been looking at additional configuration features of DRBD – which is used by Eucalyptus Walrus HA - that can be used in the Enterprise to help add robustness and [...]

这个帖子是为2011年11月所发布的《Ubuntu 11.04 Server安装配置OpenNebula 3.0》一文的升级版。本教程在Ubuntu 12.04 Server的32位版本和64位版本上都进行过测试。在设备匮乏的情况下,本教程也可以在一台笔记本电脑上完成(在这种情况下,业务内网和管理内网合并成一个网络)。文章中嵌入的图片可能看得不是很清楚,可以点击图片看到清晰大图。

[网络拓扑]

存储设备(可以是FC SAN,可以是磁盘阵列,可以是管理节点上的本地硬盘,也可以是基于MooseFS或者Ceph的分布式文件系统)通过直连管理节点,并挂载为管理节点上的一个目录/srv。

管理节点和计算节点各有两个网卡,其中一个网卡连接业务内网,另外一个网卡连接存储内网。在条件允许的情况下,建议业务内网和存储内网都使用万兆网。在不能全面使用万兆网的情况下,建议管理节点(尤其是管理节点上的存储网络)连接到交换机的万兆网口,计算节点连接到交换机的千兆网口。

业务内网的IP段为 192.168.1.*,存储内网的IP段为192.168.2...
