Why Infrastructure Parity Matters for Developers Too

Background

I’ve been working with the CTO of an online video game company to develop a container architecture for his business. The goal is to simplify the deployment of new applications as well as make it easier to go back and change the code on older applications. The desired state is environmental parity across the infrastructure — this will simplify the assignment of work on different applications to different developers. From developer laptops to production servers, the code will just work!

While video game production has unique technical and business requirements, infrastructure parity from developer laptops to production servers is a common desire that touches every industry that relies on application delivery.

3 Reasons I Should Build My Containerized Applications on RHEL and OpenShift

Red Hat has always given operations teams value in deploying Red Hat Enterprise Linux (RHEL), and that’s no different in a containerized world.  But, as a developer, why should I build on RHEL? Does the underlying operating system really affect me?

It might if you want to:

  1. get your app to production faster
  2. work on new products, not maintain old ones
  3. avoid compatibility issues at scale

(And yes RHEL is available at no cost for development use.)

A Practical Introduction to Docker Container Terminology

Updated January 13th, 2016

Background

When discussing an architecture for containerization, it’s important to have a solid grasp on the related vocabulary. One of the challenges people have is that many of the following terms are used interchangeably… often causing quite a bit of confusion for newcomers.

  • Container
  • Image
  • Container Image
  • Image Layer
  • Index
  • Registry
  • Repository
  • Tag
  • Base Image
  • Platform Image
  • Layer

 

The goal of this article is to clarify these terms, so that we can speak the same language and develop solutions and architectures leveraging the value of containers. Note that I am going to assume that you know how to run basic docker commands, but if you need a primer, I recommend starting with: A Practical Introduction to Docker Containers.

Repost – Architecting Containers Part 3: How the User Space Affects Your Application | Red Hat Enterprise Linux Blog

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.

Repost: Architecting Containers Part 2: Why the User Space Matters

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.
