When it comes to adopting containers, security is the highest adoption barrier according to 53 percent of IT operations and development professionals working with containers today. While there is no shortage of container security news, there is still some debate about the best way to properly secure containers.

Next week from 16-17 November, many of us are heading to Barcelona for DockerCon Europe 2015. If you’re heading to Barcelona as well, you can learn how developers, operations, DevOps and sysadmins are using Linux containers. From use cases to roadmaps to tutorials and advanced technical
talks, DockerCon will offer attendees a deep dive into the technology.

In Architecting Containers Part 1 we explored the difference between the user space and kernel space. In Architecting Containers Part 2 we explored why the user space matters to developers, administrators, and architects. In today’s post we will highlight a handful of important ways the choice of the user space can affect application deployment and maintenance.
While there are many ways for a given container architecture to affect and/or influence your application, the user space provides tooling that is often overlooked, namely

This morning, Red Hat announced the general availability of OpenShift Enterprise 3.1 as well as a public preview of Red Hat Atomic Enterprise Platform. Red Hat’s updated container offerings are:
- OpenShift Enterprise 3.1, the latest version of Red Hat’s application platform designed to build, deploy and run stateful and stateless applications on private and public cloud infrastructure.
- Red Hat Atomic Enterprise Platform Public Preview, an optimized container infrastructure platform for deploying, running and managing containers across the enterprise.
Both enable enterprises to develop, integrate, deploy, and manage a variety of applications consistently across a more secure, container-optimized infrastructure. If you’re looking to adopt container-based architectures, OpenShift and Atomic allow you to use Docker-formatted Linux containers to create microservices-based applications and modernize traditional workloads – all with the security of a consistent foundation based on Red Hat Enterprise Linux.

Next week, hundreds of Kubernetes enthusiasts are heading to San Francisco for KubeCon 2015, the first Kubernetes community conference. Why should you attend?
- Witness a variety of expert deep technical talks on containers and orchestrating them with Kubernetes. For example, OpenShift architect Clayton Coleman is presenting “Application Development on a Cloud-Native Platform” at 1:50 p.m. PST, on Monday, November 9, 2015. In the session, Clayton will cover workflow and tooling for application developers using Kubernetes as a development platform while still allowing developers to manage the lower level components of the system. This talk will show enhancements to core Kubernetes objects, and how they are being moved into the Kubernetes core over time.
- Learn about the future of Platform-as-a-Service.
PaaS isn’t static; it involves a constantly progressing set of technologies to enable a better approach to building and running applications. Ashesh Badani, general manager, OpenShift at Red Hat, is being joined by Google’s Craig McLuckie and others for a panel discussion around the future of Platform-as-a-Service (PaaS). Ashesh is responsible for Red Hat’s PaaS business. Check it out on Tuesday, November 10, 2015 at 11:30 a.m. PST.
- Get inspired about building highly scalable microservices-based applications.
KubeCon is your opportunity to dig deeper into how to implement microservices. Red Hatter Christian Posta helps you to make microservices a reality with “Microservices aren’t just for unicorns: meet fabric8.io”. At 9 a.m. PST on Wednesday, November 11, 2015, Christian will walk attendees through building microservices with Fabric8 on top of Kubernetes.
- Connect with other Kubernetes enthusiasts, including Red Hatters. Come by Red Hat’s booth (#1) connect with us on container security, orchestration, storage, management, and more. In addition, events outside the main conference track will allow attendees to interact with other Kubernetes enthusiasts.
If you are passionate about building highly scalable microservices-based apps, containerizing traditional apps, and/or are just getting started with Kubernetes, this is an event you won’t want to miss. For more information on KubeCon or to register for the event, please visit https://kubecon.io/.
Back in April, we provided an in-depth look into atomic updating and announced the first of many atomic updates. Since then, Red Hat Enterprise Linux Atomic Host has continued to evolve, along with the asynchronous kernel errata. What’s changed in the last few months? Let’s take a look.

From news on the latest Red Hat product releases to essays on the hottest technologies – all authored by some of Red Hat’s best and brightest – the Red Hat Enterprise Linux Blog has been working to surface the information you need. As we worked our way towards two years of posting goodness – we’ve covered everything from kpatch to containers.
That said, we have yet to ask you, our loyal readership, what you want to hear next. So… for a change of pace, we’re asking you to “select your destiny”. How does one go about “selecting their destiny”? The answer is simple: by taking part in this straw poll.
We look forward to your selection!
In Architecting Containers Part 1 we explored the difference between user space and kernel space. In this post, we will continue by exploring why the user space matters to developers, administrators, and architects. From a functional perspective, we will explore the connection that both ISV applications and in-house application development have to the user space.

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.

In March, we announced the general availability of Red Hat Enterprise Linux 7.1, the first update to our Red Hat Enterprise Linux 7 platform. In addition, we also announced the general availability of Red Hat Enterprise Linux Atomic Host, our first container-optimized host platform. Today, we are pleased to announce the beta availability of Red Hat Enterprise Linux 7.2.
Red Hat Enterprise Linux 7.2 beta includes a number of new features and enhancements – while continuing to provide the stability, reliability, and security required to meet the demands of both modern datacenters and next-generation IT environments.
Interested in learning more? For more information on the beta release of Red Hat Enterprise Linux 7.2 you can review the release notes in the Red Hat Customer Portal.
