In a commissioned study conducted by Forrester Consulting on behalf of Red Hat, 44% of IT professionals identified performance in their top three concerns for adopting container technologies. Benchmarks indicate that containers result in equal or better performance than virtual machines in almost all cases, with the runtime costs of containers as “negligible”.
What are the abstraction costs and what do you need to consider when running container-based applications on Atomic Enterprise Platform Public Preview?

When working with container-based applications, admins and developers need a place to store and share container images, a way to deploy them, as well as a way to monitor and administer them once they’re deployed. Join Red Hat software engineers Aaron Weitekamp and Stef Walter for this webcast, Using the Atomic Registry for Secure Container Image Management, on January 27th at 11:00 ET, to gain a better understanding of sharing, deploying, and managing container images.

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.

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

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.
