This presentation is a 16 slide introduction to what must be thought about when building a production cloud. Proper image management is critical engineering task.
Esta presentacion fue presentado en CampusLink 2.0. Fue la primera vez que yo he hablado profesionalmente en EspaÃ±ol. DisfrutÃ© esta experiencia demasiado y espero tener la oportunidad hacerlo de nueva en aÃ±os futuros.
This presentation walks through some of the software development processes used to develop Shiva, a mass ssh client. The development of Shiva was used as a teaching aid for a class taught at Ohio Linux Fest 2012. Shiva was used to demonstrate concepts such as good command line interface design, testing, configuration design and advanced features of Bash, such as background functions. This presentation and associated class were developed to help systems adminsitrators think more like developers.
This presentation overviews RHEL, Glusterfs, and the FUSE client. It was created for the Akron Linux User Group in May. There was a quick presentation followed by a demonstration using four virtual machines running RHEL 6.2. Three of the virtual machines were used as a Glusterfs storage pool using the open source RPMs. The fourth virtual machine was used to mount the storage pool using the FUSE client. I demonstrated the resilience of Glusterfs by pausing one of the Glusterfs storage pool nodes while the client was still connected. Since a distributed/replicated Glusterfs volume was used, the client paused for a short amount of time, then showed a listing of a directory with 1000 files in it. This was all done while the mount command on the client node showed the paused Glusterfs node being mounted, magicalâ€¦
This presentation was created for the Pittsburgh Perl Workshop 2011. It gives an overview of a fairly sophisticated set of criteria to build a large Nagios installation.
Abstract Linux Systems Administration for Power Users: This presentation was created for the Oct, 2010 Akron Linux Users Group.
