By Joshua Timberman

I look at legacy applications as opportunities: we’re really just talking about existing software that can use a little attention. — Kelsey Hightower

This week on the blog, we featured key lessons from our conversation with Kelsey Hightower about migrating to Kubernetes alongside his Allma workflow. We’ve also gathered some additional Kubernetes resources, from how-to guides to conference talks:  

How to move legacy applications to containers and Kubernetes” at Red Hat
This is an overview of using Red Hat OpenShift as the Kubernetes implementation for migrating legacy applications. OpenShift provides a number of features and benefits that make application deployment and migration much easier. Companies looking to migrate legacy applications often already have a number of Red Hat-based solutions, which should make complex migrations a more manageable task.

Chef and Kubernetes: Better Together?” by Susan Hall at The New Stack
At ChefConf 2019, I gave a talk about how Chef Software migrated some of its “legacy” applications from running on EC2 instances to running on Kubernetes. This article is an overview of some of the philosophies behind this, a link to a recording of my talk, and some additional discussion around how traditional configuration management tools fit in with a modernized Kubernetes deployment environment.

How Kubernetes became the solution for migrating legacy applications” by Swapnil Bhartiya at
This article covers some important and interesting history of how the world has modernized application deployment on containers and Kubernetes.

Fireside chat with Kelsey Hightower, part one: on Kubernetes, legacy tech, and the future of monitoring” by Anna Lugger at Sensu
This post is based on a conversation Kelsey had with Caleb Hailey and Sean Porter at the Sensu Summit in 2018. There is a link to the video in the post. When migrating legacy applications to Kubernetes, it’s important to ensure that monitoring continues to function. This conversation offers great insights into things to keep in mind, as well as components of the Sensu monitoring stack that can integrate with endpoints in Kubernetes such as Prometheus.
