Background This blog series is focused on programmers, systems administrators, and application administrators that want to run Docker in production. The subject matter ranges from workflow and practical guidelines to security and best practices in manageability. A Practical Introduction to Docker Containers A Practical Introduction to the Docker Registry Server Core Builds in the
Background As has been stated before, Docker containers do not contain all of the parts of the operating system necessary to be considered secure. That said, the advantages of using them is so compelling that many companies, large and small, have began to investigate how to run containers in a production environment. I would argue

Background As legacy applications are redesigned for the cloud, they are converted to run in a stateless manner. In newly designed applications, data flows between application code, messaging infrastructure, caches and databases seamlessly even during individual node failures of any one subsystem. When an active node fails, a new one is instantiated and placed back
Background Red Hat Software Collections 1.2 was recently released and with it, comes a different message to developers on Red Hat Enterprise Linux and CentOS. Unless you need 10 years of support for your application stack (MySQL, PHP, Ruby, Rails), use Red Hat Software Collections (RHSCL). RHSCL provides developers with the latest version of tools

Background Packaging is one of those nagging problems that has buggered me for years. When do you create your own RPM or DEB package? Of course the answer is, it depends. I have found two distinct use cases which have Basics I don’t think the use cases for this tool have been identified in this

Background One of the key advantages of using Docker is it’s centralized image management server, called a Registry Server. The Docker project, as well as Red Hat, maintain public registry servers which host supported images. The Docker project also provides an Open Source version of the Registry server which can be deployed on premise in

Background Impetus Recently, I saw a discussion was started, asking about the importance of the operating system on the LinkedIn OpenStack group: Ubuntu can overtake Red Hat in private clouds because the OS doesn’t really matter I found the conversation wildly interesting because several people expressed reasons for why they think the operating system does
Background Open Source Software Proprietary Software have very different supply chain mechanics. Programmers, Architects, and Systems Administrators need to understand the long term impact of leveraging Open Source software versus Proprietary Software. For as long as I have been programming, it has been common for programmers to leverage libraries of code. Historically, these libraries were

Background Why Docker has quite an amount of buzz around it today because it makes so many things easy that were difficult with virtual machines. Docker containers makes it easy for Developers, Systems Administrators, Architects, Consultants and others to quickly test a piece of software in a container; much quicker than a virtual machine, and

At JUDCon 2013 in Boston, Scott Cranton and I presented a talk entitled Resilient Enterprise Messaging with Fuse & Red Hat Enterprise Linux. This technical article is the follow up work from that presentation.
