Why is it that open source wins in infrastructure software? Why do websites run on Cassandra and MongoDB? Why are the biggest clouds in the world built on Linux and open source hypervisors? How come the leading cloud management platforms are open source?

The answer is surprisingly simple. The solution has emerged over the past two decades thanks to Apache, Linux, MySQL and other enormously popular software technologies. When you provide software to people who can and want to develop...

首先需要在前端节点上安装OpenNebula,具体的方法可以参见《Ubuntu 12.04 Server安装配置OpenNebula 3.8》这篇文章。

We are about to ship Eucalyptus version 3.3 – and there is no end to our pride and excitement!

The number 3 has serious meaning to us. When we released our first 3 – version 3.0 – in February of 2012, we brought to bear something the market hadn’t seen before: a cloud platform with high availability (HA) built in.

At that time, Nokia Siemens Networks (NSN) was going into production with their internal Eucalyptus cloud. Little did they anticipate that their usage would grow by...

Our demo day for milestone 6 was yesterday, and it was choice. We’re at feature completeness at this point, and we’re now on final approach for release sometime Soon-ish, as soon as we shake out all the code nasties. We’ve got some good stuff to show off on Vimeo. The basic transcript:

0:00 Eric Choi, Product Mktg Manager, with agenda/housekeeping. 1:25 Tim Cramer, VP of Engineering, sets the table for demos. 3:45 Yours Truly, VP of Community, talks (a little too long) about Eucalyptus...

For the past few months, one of my projects at Eucalyptus has been our CentOS 6 based "Silvereye" (a.k.a. FastStart) installer, which assembles multiple repositories, custom install classes, and a few helper scripts onto a DVD-sized ISO image.  One of the challenges has been that I'm a remote employee, and downloading an ISO file from our Jenkins server takes too long.  At the same time, loading the ISO into Cobbler doesn't really test the same code paths as booting a DVD.  So how can I test...

When I talk to IT organizations about using Eucalyptus to set up a private or hybrid cloud, they often ask "How do I get started?" Recently, we've published a series of Reference Architectures which are specific to common use cases deployed in the field Let's take a look at how the Dev/Test Reference Architecture might be used as a framework for building a private or hybrid cloud for Dev/Test purposes.

In many IT organizations, a gap exists between developers and the IT operations...

I have devoted my last 2 years to testing Eucalyptus. In that period the QA team and I have gone through many iterations of tools to find those that make us most efficient. It has become a never ending and enjoyable quest.

We have evolved our testing processes through the following stages:

Using command line tools exclusively Writing scripts that call command line tools and parsing their output Writing scripts using a library to make test creation easier and more efficient...

One of the questions that is often asked of me as a Cloud Solutions Architect and Consultant is: Why do I need a private cloud? This is a valid question on several levels, but rather than give the usual spiel on 'security' and 'control', I want to delve into a tangible usage scenario where a private cloud makes sense. While this is just one scenario, think about the ways that this can apply to so many more scenarios that are similar or have similar goals and end-states.

There is no...

I have recently taken a new role at Sales Engineer at Eucalyptus and one time consuming issue I keep running into with clients is image management - specifically being able to import an EBS backed image from EC2 into Eucalyptus.

The merits of this endeavor are open for debate: I would much prefer hybrid users use separate images on different clouds and simply use cloud-init scripts, or a similar mechanism, to pull up the same application stack on each of them.  That being said,...

What is software security? What makes one software product more secure than another? Is it a set of security features that it supports? Or is it a number of security tests that it passes?  Or maybe it's a set of best practices that it follows? The answer is none of the above and all of them together plus more. For example, is a product that implements a two-factor authentication more secure than the one that only relies on one factor? In theory, yes, but in practice it depends on the...
