Optimization – we’ve all heard this term a million times. Without a doubt, it is a term that is used during company meetings, in the analyst community, and is, of course, a favorite topic to “pick on” for technology cartoons. In the technology sector IT optimization “carries the day”. But, even then, “IT optimization” is a term that is often so overused that we all think we know what it is… but do we really?

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 sessions, birds-of-a-feather sessions, mini sessions, panels, workshops, 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.

For many organizations, IT modernization begins with the operating system. In the last few years, migrating workloads to Linux from RISC systems has accelerated as organizations seek to take advantage of the potential price/performance advantage of x86 blade hardware solutions. However, as open source becomes more pervasive, many enterprises are realizing additional benefits. Not only can enterprises reduce (or in some cases eliminate) their reliance on legacy systems by

While performance benchmarks are often application or industry specific they can also provide useful insights that are widely applicable. Risk analytics applications used in financial services industries have performance characteristics similar to many technical computing applications. These applications are large, compute intensive, and take full advantage of parallel processing and compute accelerators.
STAC®, the Securities Technology Analysis Center LLC (www.STACresearch.com), provides technology research and testing tools including

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.

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

In this article I want to talk about a runC container which I want to migrate around the world while clients stay connected to the application.
In my previous Checkpoint/Restore In Userspace (CRIU) articles I introduced CRIU (From Checkpoint/Restore to Container Migration) and in the follow-up I gave an example how to use it in combination with containers (Container Live Migration Using runC and CRIU). Recently Christian Horn published an additional article about CRIU which is also a good starting point.
In my container I am running Xonotic. Xonotic calls itself ‘The Free and Fast Arena Shooter’. The part that is running in the container is the server part of the game to which multiple clients can connect to play together. In this article the client is running on my local system while the server and its container is live migrated around the world.
This article also gives detailed background information about

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

Recent Red Hat Enterprise Linux releases see an expansion in support of the smart card related use cases. However customers usually have a mixed environment and standardize on a specific version of Red Hat Enterprise Linux for period of time. It is important to understand the

The open source community and the IT industry as a whole continue to discuss how they can use different hardware architectures to solve hard computational problems and address specific workloads. Customers value choice in their technology implementations, and choice is a key benefit of open source solutions. To best meet these needs, the software ecosystem has to
