Red Hat Virtualization at Red Hat Summit 2018

Hi folks, in this post I wanted to share with you some of the cool activities we have happening next week at the Red Hat Summit in San Francisco. For virtualization there’s a ton of things going on – to say that we are ‘RHV’ed up is an understatement! (sorry, @RedHatRex wrote that joke…) Here’s a short video that will get you goin on RHV:

Ultimate Guide to Red Hat Summit 2018 Labs: Hands-on with RHEL

This year you’ve got a lot of decisions to make before you got to Red Hat Summit in San Francisco, CA from 8-10 May 2018.

There are breakout sessionsbirds-of-a-feather sessionsmini sessionspanelsworkshops, and instructor led labs that you’re trying to juggle into your daily schedule. To help with these plans, let’s try to provide an overview of the labs in this series.

In this article let’s examine a track focusing only on Red Hat Enterprise Linux (RHEL). It’s a selection of labs where you’ll get hands-on with package management, OS security, dig into RHEL internals, build a RHEL image for the cloud and more.

The following hands-on labs are on the agenda, so let’s look at the details of each one.

My Journey from BASIC to Linux

This post is brought to you by Command Line Heroes, an original podcast from Red Hat.

I think of computing today as being the convergence of at least three major threads that were once largely apart from each other. There were the proprietary hardware and software stacks: mainframes and their minicomputer counterparts. There was the proto-Internet and Unix, proprietary in their own way but leading to Linux and open source. And there was the personal computer.

From Manual to Automated DevOps: One Man’s Journey

This post is brought to you by Command Line Heroes, an original podcast from Red Hat.

My journey, as one might say, in search of the Holy Grail or the great unicorn called DevOps, began well over 20 years ago; yet I never knew it at the time… Actually, it began in 1984 when I was 13 and got my own first computer, a Commodore VIC-20. It wasn’t the first computer that I had ever used but it was mine. I pushed that system with 3 ½ KB of RAM to its limits. Technology has grown by leaps and bounds in such a short timespan. Since those days, I’ve worn many hats. I’ve owned my own company, I’ve helped tech-edit books, and I’ve been pretty active in the open source community. Workshops, social media, MeetUps, Red Hat user groups (RHUGs), virtualization technology user groups (VTUGs), etc. have all allowed me to share and learn at the same time.

Fast forward 10 years, I’m a sergeant in the Army. Sometimes, when in garrison (which was rare), I got tasked out to a bit of side work on UNIX systems simply because nobody knew how to use them. These puppies were coupled together with many pre-internet technologies.

Understanding the Concepts Behind Virtual Data Optimizer (VDO) in RHEL 7.5 Beta

In the Red Hat Enterprise Linux 7.5 Beta, we introduced virtual data optimizer (VDO). VDO is a kernel module that can save disk space and reduce replication bandwidth. VDO sits on top of any block storage device and provides zero-block elimination, deduplication of redundant blocks, and data compression. These are the key phases of the data reduction process that allows VDO to reduce data footprint on storage. VDO applies these phases inline and on-the-fly.  Now, lets see what happens in each process (download the beta yourself and try):

Expand your reality with Red Hat at SuperComputing17

Over the years, the SuperComputing conference has become a focal point for many global supercomputing sites to showcase their capabilities and compete for a placement on the coveted Top500 list. Many powerful supercomputers and new technological advances are showcased during the conference, making it perhaps no surprise that Red Hat is planning to be at SuperComputing17 next week to demonstrate our latest high-performance computing (HPC) solutions (booth #1763).

Red Hat has a packed agenda for the show – here’s more about what you can expect to see from us during SuperComputing17.

Keeping Pace with Multiple Architectures (Part 2)

In our first post of discussing Red Hat’s multi-architecture strategy, we focused on the disruptive nature of enabling new and rapidly-evolving architectures and how this enablement necessitates a different set of product requirements to fulfill our vision of providing a consistent and familiar experience to our customers across multiple hardware architectures. While we have been working with many original equipment manufacturers (OEMs) on x86_64-based servers for years, we have seen interest from our customer base in delivering parity across multiple architectures, including IBM Power Little Endian (ppc64le) and ARMv8-A (aarch64).

So what exactly are we doing with our partners to make this

Picking your Deployment Architecture

In the previous post I talked about Smart Card Support in Red Hat Enterprise Linux. In this article I will drill down into how to select the right deployment architecture depending on your constraints, requirements and availability of the smart card related functionality in different versions of Red Hat Enterprise Linux.

To select the right architecture for a deployment where users would authenticate using smart cards when logging into Linux systems you need to
