It’s been a busy few weeks for us on the Atomic Host team, and we’re excited to announce the release of Red Hat Enterprise Linux Atomic Host 7.2.5! This is a big one too. For those not familiar with our release cadence, we release a new version of Atomic Host every six weeks. This enables us to balance the reliability of Red Hat Enterprise Linux with exciting new features and capabilities from our Project Atomic upstream community in a production ready, supportable manor.

 

Now, let’s walk through some key new features in Atomic Host:

Schrodinger’s Container: How Red Hat is Building a Better Linux Container Scanner

The rapid rise of Linux containers as an enterprise-ready technology in 2015, thanks in no small part to the technology provided by the Docker project, should come as no surprise: Linux containers offer a broad array of benefits to the enterprise, from greater application portability and scalability to the ability to fully leverage the benefits of composite applications.

But these benefits aside, Linux containers can, if IT security procedures are not followed, also cause serious harm to mission-critical operations. As Red Hat’s Lars Herrmann has pointed out, containers aren’t exactly transparent when it comes to seeing and understanding all of their internal code. This means that tools and technologies to actually see inside a container are critical to enterprises that want to deploy Linux containers in mission-critical scenarios.

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

What is Deep Container Inspection (DCI) and Why is it Important?

The format of container images is at the center of industry attention because it is so important to the adoption of containers.  With the advent of the Open Container Initiative (OCI), it seems appropriate to compare container images to network protocols.  Before TCP/IP became the defacto standard network protocol stack, each vendor was left to devise their own.  Some leveraged IPX/SPX, while others standardized on AppleTalk.  This made it difficult to create robust tooling.  Much like network protocols, standardizing the bit level format of a container image, allows the industry to focus on higher level business problems, and more importantly, their respective solutions.
