Looking Back on Containers in 2015

Woah.  2015 went by really quickly.  I do suppose it’s not all that surprising as time flies… especially when you’re having fun or… getting older (you pick).  In fact, we’ve already put 2 percent of 2016 behind us!  That said, before we get too deep into “the future”, and in consideration of Janus having not one but two faces, let’s take a quick trip down memory lane…

Without a doubt, 2015 was an exciting year for all things “container”, especially here at Red Hat.

To recap, the year started off with a bang when we announced the general availability of Red Hat Enterprise Linux Atomic Host alongside Red Hat Enterprise Linux 7.1.  Then – less than two months later

Configuring and Applying SCAP Policies During Installation

Over the past few decades we have seen great advancements in the IT industry.  In fact, the industry itself seems to be growing at an increasingly faster pace.  However, as the industry grows so to does its evil twin – the figurative sum of all threats to IT security.

On the bright side, along with a steady stream of ever-evolving security issues and threats, there has also been a great effort to mitigate and, when possible, entirely eliminate such threats.  This is accomplished by either fixing the bugs that allowed these issues and threats to exist (in the first place) or by fixing the configurations and protectionary mechanisms of systems so as to prevent attackers from finding success.

As 2015 has been no stranger to news stories about data leakages, various security flaws, and new types of malware – one could easily conclude that “the dark side” is winning this seemingly eternal race.

However, taking the complexity of today’s IT solutions into account

The History of Containers

Given the recent massive spike in interest in Linux Containers, you could be forgiven for wondering, “Why now?”. It has been argued that the increasingly prevalent cloud computing model more closely resembles hosting providers than traditional enterprise IT, and that containers are a perfect match for this model.

Despite the sudden ubiquity of container technology, like so much in the world of open source software, containerization depends on a long series of previous innovations, especially in the operating system. “One cannot resist an idea whose time has come.” Containers are such an idea, one that has been a long time coming.

Architecting Containers Part 1: Why Understanding User Space vs. Kernel Space Matters

Perhaps you’ve been charged with developing a container-based application infrastructure?  If so, you most likely understand the value that containers can provide to your developers, architects, and operations team. In fact, you’ve likely been reading up on containers and are excited about exploring the technology in more detail. However, before diving head-first into a discussion about the architecture and deployment of containers in a production environment, there are three important things that developers, architects, and systems administrators, need to know

What’s New with Red Hat Enterprise Linux System Administration? Find Out.

On Thursday, July 30, 2015, Red Hat will be presenting a free webinar for system administrators, engineers, and architects to learn what’s new with Red Hat Enterprise Linux.

During this webinar Red Hat curriculum manager and Red Hat Certified Architect, Michael Jarrett, will teach you about the new and changed features in Red Hat Enterprise Linux 7. He’ll focus on system administration topics that have changed significantly or are particularly important in Red Hat Enterprise Linux 7. He’ll also discuss the skills and expert knowledge needed to measure and influence performance on these systems.

Then Pete Hnath, director of curriculum, will show you how easy it is to train on Red Hat Enterprise Linux 7 and update your skills with the new Red Hat Learning Subscription, a year-long, all-access pass to more than 30 online learning courses.

What’s Next for Containers? User Namespaces

What are user namespaces? Sticking with the apartment complex analogy, the numbering of users and groups have historically been the same in every container and in the underlying host, just like public channel 10 is generally the same in every unit in an apartment building.

But, imagine that people in different apartments are getting their television signal from different cable and satellite companies. Channel 10 is now different for for each person. It might be sports for one person, and news for another.

Historically, in the Linux kernel, there was a single data structure which held users and groups. Starting in kernel version 3.8

Identity Management and Two-Factor Authentication Using One-Time Passwords

Two-factor authentication, or 2FA, is not something new. It has existed for quite some time and in different forms. What is a ‘factor’? A factor is something you have, something you know, or something you are. For example, if we combine a PIN that you know, with your fingerprint, we get a 2FA based on biometrics. In practice, biometric solutions are not often used because it’s not especially difficult to steal someone’s fingerprint (…and it is quite hard to revoke or replace your finger). The more practical approach to two-factor authentication is to combine something you know, a PIN or password, with something you have.

Something you have often comes in form of
