My previous post talked a little bit about new functionality from (new and updated) ec2-related modules in the Ansible 1.0 release. In this post I’ll go through the practical example of launching multiple instances with the module and then configuring them with a workload. In this case the workload will be the Eucalyptus User Console
For those who are unfamiliar with ansible, check...
People love BSD and it bothers me, that they cant run it on Eucalyptus private cloud inside their organisation. So, I took the challenge on building an openbsd image (EMI) which we could then run on Eucalyptus.
The version of openbsd used is 5.2 amd64 and Eucalyptus 3.2.0 on CentOS 6.3. Note that there were problems with running an instance store backed EMI and hence I ended up running an instance from boot-from-EBS EMI.
For the sake of simplicity, this post is...
This last weekend I was over at FOSDEM 2013, where 5,000
geeks descended onto the ULB university in Brussels, Belgium for a huge free and open source
It was my first time at FOSDEM after many years of nearly attending and
the first thing that struck me was the size. 5,000 people
in attendance over the two days, 390hrs of talks and every talk was...
You may be forgiven for thinking that a version 1.0 software release indicates some sort of significant milestone for the lifecycle of a project. Perhaps in many cases it does but with Ansible, not so much. Michael DeHaan articulates it much better than I could in this post to the project mailing list. My personal experience from using Ansible since v0.8 is that each release delivers consistency...
You’ve deployed and setup a private Cloud platform but now what? You need an application!
I’ve been experimenting with a number of technologies to generate workloads and give some demos to
prospective Eucalyptus customers. A NoSQL database seems like a great use-case to demo as the technology benefits from
being designed for scale-out workloads and this happens to be exactly what an IaaS Cloud does best.
There are an abundance of NoSQL implementations (Cassandra,...
Eucalyptus comes with its own High Availability (HA) feature from version 3.0 and with the passage of time, it is becoming more and more stable with every release. With recent release (3.2.0 and onwards), it has got few behavioral changes, … Continue reading ...
I predict 2013 will be known for many things with regards to Eucalyptus as a company, but perhaps nothing will be more important to me personally than the decision alluded to in the title of this post. This year, Eucalyptus Professional Services is going open. All the way open.
There are a number of reasons we are making this shift, but the most important one is culture. If we truly are an open source company, does it make sense for us to develop closed-source intellectual property,...
A class method in python differs from an instance method in a couple important ways:
- It binds to a class rather than an instance (hence its name). Thus, its first argument is a class, often called
clsrather than the usual
- It can be called on both an instance of a class and the class itself.
In general, they behave similarly, but one area in which they can differ is when we go to override the class method:...
