Big Data: Datameer: How-to: Incrementally Load Data from Relational Sources in Datameer In case you haven’t noticed, we are always striving to maximize efficiency and ease for our customers. As such, one of my favorite features in Datameer is the ability to incrementally load data from relational sources. This allows you to keep fresh data in your Hadoop system while also putting minimal stress on the upstream relational system since you’re only adding changed or updated records to your environment.

DevOps: Rackspace: Rolling Deployments With Ansible and Cloud Load Balancers Recently a fellow Racker wrote a great post about zero downtime deployments. I strongly believe in the principals he described. In his example, he used Node.js to build a deployment script to accomplish the goal, and I want to explore how this could be done with Ansible and the Rackspace Cloud. Read more.
OpenStack: Adam Young: Configuring mod_nss for Horizon Horizon is the Web Dashboard for OpenStack. Since it manages some very sensitive information, it should be accessed via SSL. I’ve written up in the past how to do this for a generic web server. Here is how to apply that approach to Horizon. Read more.
Adam Young: MySQL, Fedora 20, and Devstack Once again, the moving efforts of OpenStack and Fedora have diverged enough that devstack did not run for me on Fedora 20. Now, while this is something to file a bug about, I like to understand the issue to have a fix in place before I report it. Here are my notes. Read more.
Adam Young: Packstack to LDAP While Packstack makes it easy to get OpenStack up and running, it does not (yet) support joining to an existing Directory (LDAP) server. I went through this recently and here are the steps I followed. Read more.

Cody Bunch: Basic Hardening with User Data / Cloud-Init The ‘cloud’ presents new and interesting issues around hardening an instance. If you buy into the cattle vs. puppies or cloudy application building mentality, your instances or VMs will be very short lived (Hours, Weeks, maybe Months). The internet however, doesn’t much care for how short lived the things are, and the attacks will begin as soon as you attach to the internet. Thus, the need to harden at build time. What follows is a quick guide on how to do this as part of the ‘cloud-init’ process. Read more.
Cody Bunch: Basic Hardening Part 2: Using Heat Templates Specifying that as user-data every time is going to get cumbersome, as will managing your build scripts if you are using CLI tools and the like. A better way, is to build it into a Heat Template. This allows for some flexibility in both version controlling it as well as layering HOT templates to a desired end state (HOT allows for template nesting. Read more.

Matt Fischer: Keystone – using stacked auth (SQL & LDAP) Most large companies have an Active Directory or LDAP system to manage identity and integrating this with OpenStack makes sense for some obvious reasons, like not having multiple passwords and automatically de-authenticating users who leave the company. However doing this in practice can be a bit tricky. Read more.

Mirantis: OpenStack Icehouse: More Than Just PR Is your head swimming with Icehouse information yet? By now you have certainly heard that the ninth OpenStack’s version, Icehouse, has been released. The most prominent features, such as rolling compute upgrades, improved object storage replication, tighter integration of networking and compute functionality, and federated identity services, have gotten a lot of airtime, but with more than 350 implemented blueprints, there’s a lot more below the surface of this particular iceberg. Here at Mirantis, we’ve been doing a lot of work with Icehouse, and we’ll be going into some technical depth on many of the new features of Icehouse in our webinar on April 24. In the meantime we wanted to give you a taste of what’s available. Read more.
