user story mapping

Every Agile Software Project Needs a User Story Map

Rusty Divine Agile, Microservices Leave a Comment

In this blog, I share an example of a real-world, agile enterprise modernization project that benefited from a User Story Map.

I’m the team lead for a project to convert a business solution from COBOL to a .NET microservices architecture. Other than some interesting challenges with designing a robust microservices solution, the business logic is very straightforward – input files are processed, databases queried, output files are produced and dropped in a folder, and our goal is to match the output produced by the COBOL solution perfectly.

Yet, we lost our way fairly early on in the project because we had a typical prioritized backlog. Unfortunately, even on a straightforward, well-defined project with an engaged team, we still managed to veer off course.

Our project manager started asking questions about where we were in the project and where we were going. I struggled to answer those questions because I couldn’t make sense of all that was in our backlog. It was around this time that I took a spreadsheet and created our first User Story Map….



OpenShift Quick Start: Build, Deployment and Pipeline

David Pitt Microservices, OpenShift, Tutorial Leave a Comment

This post is a continuation of our hands-on OpenShift Quick Start blog series.

In the first post we introduced OpenShift & its features. In part two, you worked to get OpenShift running locally & adding a Container with an API service to a Pod. In part three, you worked on scaling pods and managing Cluster with the CLI.

This blog continues that series, introducing the automated Continuous Integration / Continuous Delivery (CICD) features of the OpenShift platform using both the Web Console and the Command Line. A hands-on exercise will then show how a Jenkins build Pipeline can be customized…



OpenShift Quick Start: CLI

This post is a continuation of our hands-on OpenShift Quick Start blog series. In the first post we introduced OpenShift, and in part two, you worked to get OpenShift running locally & adding a Container with an API service to a Pod. Make sure you’ve completed that step prior to starting the continued exercise below!

The previous blogs in this series managed OpenShift using the web admin user interface. However, everything that can be done with the user interface can also be done from using the CLI (Command Line Interface). Arguably, developers prefer to interact with text commands, but that’s a generalization.

In this post, we’ll demonstrate common OpenShift commands can be done in the web admin from the command line.



OpenShift Quick Start

Our previous blog in the series introduced RedHat’s OpenShift solution that provides a way for enterprise teams to implement their own PaaS. Essentially, it sits atop the Docker-based Kubernetes platform to provide a ready-to-use DevOps platform.

This blog introduces two hands-on exercises (taken from our OpenShift Course), that work to walk you through the following tasks:

– Installing OpenShift locally
– Adding a Container with an API service to a Pod

Unfortunately, it will take more than this quick start blog to get OpenShift installed and enabled in an enterprise. That said, developers, system admins, and any party that may be working on or responsible for the platform, will benefit from understanding how to get OpenShift up and running on a local machine as shown in this blog.



Managing Docker Containers with OpenShift and Kubernetes

Casey Justus Docker, Microservices, Technology Snapshot Leave a Comment

For the last few years, Docker containers have been all the rage in the DevOps world. After all, what’s not to like? They allow you to strip out 99% of stuff in your VM and just deploy your code.

Containers can save resources, speed deployment, scale well and offer more fault tolerance. But how do you manage them?

In my experience, the Docker Machine and Docker Swarm stack hasn’t lived up my to expectations. It has a limited API, no support for monitoring and logging, and much more manual scaling. AWS’s EC2 containers scale well, but you’ll be locked into Amazon.

In my opinion, the best current stack for Docker containers includes Kubernetes and OpenShift. In this blog I will give a brief introduction to Kubernetes + OpenShift with an eye for what they do well…
