One of the questions that I am often asked by customers looking at Eucalyptus for a Private Cloud is "how can I use NFS with Eucalyptus?" The scenario is usually one where the customer has deployed a NetApp SAN and prefers to use NFS over iSCSI or has deployed another highly-scalable distributed storage platform, like GlusterFS, with NFS exports.

In a normal HA deployment, Eucalyptus uses local disk for the Walrus storage and iSCSI SAN storage from a supported SAN (NetApp, EMC VNX or...

Implementing a computing cloud using your local resources. Open source. Interface-compatible with the leading public cloud. Installation as a one-button activity.

You will find those words in the famous email below from exactly five years ago when Eucalyptus 1.0 was announced and released. Eucalyptus continues to stick to the same vision.

In 2008, Eucalyptus was the most modern on-premise cloud platform you could find. And, arguably, it’s still true today. Only Eucalyptus...

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...

A few months ago we announced our intention to open source the Eucalyptus Certified Professional on Eucalyptus 3 (EUCA3) exam item bank. It is my distinct pleasure to formally announce the immediate availability of this document on GitHub. You can find the entire item bank...

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...
