The paradigm hasn’t changed since the advent of software: Applications run, and platforms are what they run on. But the underlying principles of application design and deployment do change every now and then – sometimes drastically, thanks to quantum-leap developments in infrastructure.
For instance, application design principles changed dramatically when the PC, x86 architecture, and client/server paradigm were born in the '80s. And it happened again with the advent of the web and...
At the recent AWS Summit San Francisco, AWS SVP Andy Jassy made a point of saying that choosing between private and public clouds is not an all-or-nothing proposition. He said that when customers ask him if they need to be either "all in to AWS, or all in on a private cloud" he tells them the answer is no. He then went on to present six use cases organizations should consider when moving to the cloud. It was interesting to note that the first one on his list was dev & test.
We...
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...
［1］前端节点的配置
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。
为了简单期间，我们使用前段节点所提供的NFS服务作为ESXi节点的存储设备。在创建NFS服务的时候需要export两个目录：
$ sudo vi /etc/exports /var/lib/one/datastores/0 *(rw,sync,no_subtree_check,root_squash,anonuid=10000,anongid=10000) /var/lib/one/datastores/1 *(rw,sync,no_subtree_check,root_squash,anonuid=10000,anongid=10000)

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...
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...
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...
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...
