OpenLDAP: A comparison of back-mdb and back-hdb performance
One of the biggest changes to OpenLDAP in years has made its way into the latest OpenLDAP 2.4 releases, and that is a brand new backend named "back-mdb". This new backend leverages the Lightning Memory-Mapped Database from Symas. To see why this new backend was introduced, it is useful to look at the differences in performance and resource utilization between old BDB based back-hdb and the new LMDB based back-mdb.
Introducing Micro QA
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…
Demo of Eucalyptus hotness: 3.3 milestone 6
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.
What's new in Ansible 1.1 for AWS and Eucalyptus users?
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 becoming so popular so quickly.
Exclusive: Startup AnsibleWorks pitches open-source IT configuration, deployment tool
A couple of former Red Hat (s rhat) veterans think there's an easier way to configure, deploy and manage IT across an organization and founded AnsibleWorks to attack that problem.
Systems administrators and developers want one tool for deployment, configuration and management -- they don't want to deal with agents and add-ons, said Said Siouani, CEO of Santa Barbara, Calif.-based AnsibleWorks.
Deploying Eucalyptus via Ansible playbook(s)
The first cut of the Ansible deployment playbook for deploying Eucalyptus private clouds is ready. I've merged the first "release" into the master branch here: https://github.com/lwade/eucalyptus-playbook. Feedback and contributions are very welcome, please file issues against the project.
This playbook allows a user to deploy a single front-end cloud (i.e. all component on a single system) and as many NC's as they want.
Run Appscale on Eucalyptus
Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over a network (typically the Internet). - Wikipedia
According to Wikipedia currently there are few popular service models exist.
1. Infrastructure as a service (IaaS)
2. Platform as a service (PaaS)
3. Software as a service (SaaS)
So, I have an Eucalyptus cloud, which is great, serves as AWS-like IaaS platform.
Using Scalr for Automation of your Eucalyptus Cloud
Introduction
I have been using Eucalyptus heavily (as a quality engineer it is my day to day) for the past 1.5 years. I know the ins and the outs of system and am constantly tracking new features and bug fixes that arrive. With this knowledge it makes me a prime candidate to find out how other pieces of the cloud story can integrate with Eucalyptus.
What's New in Euca2ools 3, Part 1: A User's Perspective
Version 3 of euca2ools, slated for release in just a couple months, gives the command line suite a much-needed refresh that makes it both easier to write and easier to use. Most of the innovation here involves changes to the platform upon which it is built. I will cover those changes from a developer's perspective in future blog posts, but today I'm going to focus on what euca2ools 3 brings to the table for developers and other users alike.
Writing my first Ansible module: ec2_vol
As is probably quite evident, I've recently been using Ansible to deploy workloads into EC2 and Eucalyptus. One of the ideas behind this is the convenience of being able to leverage the common API to achieve a hybrid deployment scenario. Thanks to various folk (names mentioned in previous posts) we have a solid ec2 boto-based Python module for instance launching. One thing I wanted to do when spinning up instances and configuring a workload was to add some persistent storage for the application.
