Michigan Red Hat Enterprise User Group

Thursday, May 8th, 2014 from 1:00 PM – 7:00 PM

Are you a programmer, architect, or systems administrator that leverages Open Source, Red Hat technology in a business critical environment? Do you wish that you could go to Red Hat Summit, but can’t find budget for travel? Then, this local user group is for you.

The Michigan Red Hat Enterprise User Group is a place for technical users to share technical content and best practices on a range of Red Hat technologies, including JBoss, Red Hat Enterprise Linux, Fuse, Red Hat Enterprise Virtualization, and OpenStack.

Our second quarterly meeting is on May 8th, 2014 and will include the following technical agenda:

01:00 – 01:30PM Welcome
01:30 – 02:00PM Red Hat News, Red Hat Summt Recap (Scott McCarty)
02:00 – 03:00PM Infrastructure as Code: Modern Systems Administration with Puppet (Sean Millichamp & Kevin DeGraaf)
03:00 – 04:00PM TBA (TBA)
04:00 – 05:30PM Open Discussion, Appitizers, and Drinks
05:30 – 06:30PM Core Builds in the Age of Cloud (Scott McCarty)
06:30 – 07:00PM Closing & Future Topics Discussion

If you are interested in learning more, stop by and check it out, drinks and food will be provided. We are building a local community around Open Source technology in the enterprise.

Talk 1: Infrastructure as Code: Modern Systems Administration with Puppet

Configuration management and the infrastructure-as-code paradigm have fundamentally redefined Linux systems administration. Brittle shell scripts and ad-hoc methods have given way to powerful declarative tools that reliably enforce consistency at scale. This talk will explain why the new approach is so powerful and describe how Puppet fits into the picture. We will briefly cover the Puppet language, the interaction between Puppet agents and masters, and related tools such as Facter, Hiera and PuppetDB. A question-and-answer period will follow, time permitting.

Marc Skinner will present on “RHEL Performance Tuning” which will walk
through three performance profiles that system administrators routinely
face.  The presentation will provide insight into the ease of tuning
while exploring the tooling that is available in every OS instance.

Talk 3: Core Builds in the Age of Cloud

As legacy applications are re-architected for the cloud, they are converted to run in a stateless manner. In newly designed applications, data flows between application code, messaging infrastructure, and database seamlessly even during individual node failures of any one subsystem. When an active node fails, a new one is instantiated and placed back into the pool, but what happens when the infrastructure required to build a replacement node fails?Join Red Hat’s, Scott McCarty, Solutions Architect, as he discusses the issues faced in designing and supporting core builds in a cloud work flow. Scott, will delve into the nuanced challenges tackled to provide better availability in a cloud environment.Real World Examples & Solutions:
* Kickstart
* Puppet
* Image Maintenance
* API Contracts & Maintenance
* Handling Subsystem Upgrades
* Testing

As infrastructure architects and support teams begin to engage in the process of providing a store front of core builds and services for their internal customer, service contracts will become increasingly important. Scott will discuss practical procedures for building, testing, maintaining, and facilitating a culture of learning within infrastructure teams guided by DevOps.
