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...

Background

Big Data has been a hot topic over the last few years.  Big Data on public clouds, such as AWS’s Elastic MapReduce, has been gaining even more popularity as cloud computing becomes more of an industry standard.

R  is an open source project for statistical computing and graphics.  It has been growing in popularity for doing  linear and nonlinear modeling, classical statistical tests, time-series analysis and others, at various Universities and companies.

Reblogged from Take that to the bank and cash it!:

I thought the Ansible 1.0 development cycle was busy but 1.1 is crammed full of orchestration goodness.  On Tuesday, 1.1 was released and you can read more about it here: http://blog.ansibleworks.com/2013/04/02/ansible-1-1-released/

For those working on AWS and Eucalyptus, 1.1 brings some nice module improvements as well as a new cloudformation and s3 module.  It's great to see the AWS-related modules...

For those working on AWS and Eucalyptus, 1.1 brings some nice module improvements as well as a new cloudformation and s3 module.  It’s great to see the AWS-related modules becoming so popular so quickly.  Here are some more details about the changes but...

In Part 1 of this blog series, “Adventures in NoSQL, part1”, I deployed a single
instance of MongoDB and used Python’s tweetstream module to fill a collection with a data feed from Twitter.
In part 2, “Adventures in NoSQL, part2”, I took this single MongoDB server
and converted it to a highly available replicaset, so that the data was stored on 3 servers for redundancy.

In this post, I’ll explore using Sharding to scale out your data for performance,
so that as...
