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/.
In a recent blog post on the appc spec, I mentioned Project Atomic’s evolving Nulecule [pronounced: noo-le-kyul] spec as an attempt to move beyond the current limitations of the container model. Let’s dig a bit deeper into that.
