The first cut of the Ansible deployment playbook for deploying Eucalyptus private clouds is ready. I’ve merged the first “release” into the master branch here: https://github.com/lwade/eucalyptus-playbook. Feedback and contributions are very welcome, please file issues against the project.
This playbook allows a user to deploy a single front-end cloud (i.e. all component on a single system) and as many NC’s as...
In our previous blog entries in this series, we have examined how networking and application stack considerations affect good cloud design. In this entry, we will take a look at how to design for storage in the cloud.
Cloud Storage Considerations
The results of your application research drives cloud storage design. Based on the data gathered about applications, we can determine how much storage being used will be ephemeral and how much must be persistent. We then...
Few years back I heard Santa Barbara referred as Silicon Beach. The first Cloud Meetup confirmed the rumor. The kick-off meetup, was co-organized between AppScale and Eucalyptus, and it was held at AppScale HQ. We got a recording of the meetup (a better...
Recently, we released our latest milestone build for Eucalyptus 3.3. Go take it for a spin. This is a big one, since it incorporates, for the first time, functional versions of the “Big Three” AWS services we’ll be releasing later this spring: Autoscaling, Elastic Load Balancing, and Cloudwatch. It also presents a good opportunity to step back and look again at our AWS compatibility story....
最近需要在一台没有光驱的上网本上通过FastStart装一个Eucalyptus 3.2.1。比较简便的办法，看来是将ISO转录到U盘上，然后通过U盘启动上网本并进行安装。
通过Google查找了一下，有一个叫做UNetbooin的工具，可以将ISO转录成可启动U盘。这个工具有Windows、Linux和Mac几个不同的版本，可以通过下面这个链接下载：
http://unetbootin.sourceforge.net/
我在Mac上下载并运行UNetbooin这个工具，选择下载到的ISO文件（faststart-3.2.1.iso），并从设备列表中选择正确的U盘，点击OK按钮将ISO文件转录到U盘上（如下图所示）。大概过了两三分钟时间，就完成了转录。完成转录之后，还需要将ISO文件（faststart-3.2.1.iso）拷贝到U盘的根目录。

In a cloud environment, where resource virtualization and multi-tenancy are some of the key features, security is something that simply cannot be ignored. In Eucalyptus, we invest a lot of effort into building software that is not only robust and easy to use, but is also secure and allows for building secure clouds. We also believe that the most effective way of building secure software is to be proactive about it and address security concerns before they become vulnerabilities.
There...
In the previous entry in this series, we took a look at networking considerations when designing a Eucalyptus cloud. In this entry, we will take a look at application stack considerations.
Application Stack Considerations
The second area to be probed in terms of a Eucalyptus Solutions Architecture is the application stack. This is just as, if not more important than networking as many application workloads are not optimized for the cloud. With the assumption that the use...
Back in Jason's post on "Open Consulting: Announcing EucaStart 2.0", we announced a major change to our EucaStart offering these changes include a more rigid structure to the EucaStart process but also a completely transparent process that will be open for all to modify and implement. We hope this will help guide our users, customers and partners to setup successful...
