If you’re heading to DockerCon 16 next week in Seattle, connect with us to see why Fortune 500 organizations trust Red Hat for enterprise deployments. Red Hat subject matter experts will be onsite to walk you through real-world use cases for securely developing, deploying and managing container-based applications.
Attend the State of Container Security Session
Join two of Red Hat’s Docker contributors discussing the state of container security today. Senior Software Engineer Mrunal Patel and Thomas Cameron, Global Evangelist of Emerging Technology are presenting on how you can secure your containerized microservices without slowing down development.

In Architecting Containers Part 4: Workload Characteristics and Candidates for Containerization we investigated the level of effort necessary to containerize different types of workloads. In this article I am going to address several challenges facing organizations that are deploying containers – how to patch containers and how to determine which teams are responsible for the container images. Should they be controlled by development or operations?
In addition, we are going to take a look at

Many development and operations teams are looking for guidelines to help them determine what applications can be containerized and how difficult it may be. In Architecting Containers Part 3: How the User Space Affects Your Applications we took an in depth look at how the user space affects applications for both developers and operations. In this article we are going to take a look at workload characteristics and the level of effort required to containerize different types of applications.
The goal of this article is to provide guidance based on current capabilities and best practices within

In our previous posts, we’ve explored the Red Hat container ecosystem, the Red Hat Container Development Kit (CDK), OpenShift as a local deployment and OpenShift in production. In this final post of the series, we’re going to take a look at how a team can take advantage of the advanced features of OpenShift in order to automatically move new versions of applications from development to production — a process known as Continuous Delivery (or Continuous Deployment, depending on the level of automation).

In a previous blog post we took a look at the Red Hat Container Development Kit (CDK) and how it can be used to build and deploy applications within a development environment that closely mimics a production OpenShift cluster. In this post, we’ll take an in-depth look at what a production OpenShift cluster looks like — the individual components, their functions, and how they relate to each other. We’ll also check out how OpenShift supports scaling up and scaling out applications in a production environment.

IT decision makers seem to be up in arms regarding discussions on “next generation” technologies. In the past three months it has been nearly impossible to hold a conversation where the terms cloud, OpenStack, or (Linux) containers don’t surface. Hot topics and buzzwords aside, it has become clear (to me) that the right mix of market conditions are causing organizations to express a renewed interest in enterprise virtualization.
Many organizations are now ready to adopt the next generation of server hardware. The popular Ivy Bridge and Sandy Bridge chipsets from Intel are four to five years old and those who purchased such hardware tend to refresh their equipment every four to five years. In addition, we see Intel Haswell technology approaching its third anniversary. Organizations that lease hardware on a three year cycle will also be looking at what the next generation of hardware has to offer.
What does a potential wave of hardware refresh have to do with a renewed interest in enterprise virtualization? To no one’s surprise

There is a lot of confusion around which pieces of your application you should break into multiple containers and why. I recently responded to this thread on the Docker user mailing list which led me to writing today’s post. In this post I plan to examine an imaginary Java application that historically ran on a single Tomcat server and to explain why I would break it apart into separate containers. In an attempt to make things interesting – I will also aim to

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.

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.

Red Hat recently announced the availability of Red Hat Atomic Enterprise Platform as a public preview. What key capabilities does Red Hat Atomic Enterprise Platform provide and what materials are available for you to get started? Attend the webcast on Wednesday, December 16, 2015 from 11:00 AM to 12:00 PM (ET), to find out.
