The Importance of Culture in Software Development

A few weeks ago at Cloud Foundry Summit, I had the chance to grab a few of our partners and talk about how culture plays a part in the software development process. While appropriate tools are very important, it is only part of the story. Culture will make or break any change initiative regardless of […]

Eirini: Mapping Code into Containers

There has been a lot of noise recently about the Project known as Eirini. I wanted to dig into what this project was in a little more detail. If you weren’t already aware, its goal is to allow Cloud Foundry to use any scheduler but it’s really for allowing the workloads […]

Why you might want to build your own custom buildpack (And how to!)

A PaaS can be viewed at as a method that takes different streams of data and combines them into a working application. For SUSE Cloud Application Platform, we take the application code, buildpack, environment variables, service descriptions and output a configured and running container. Each of these pieces can come from a different person or […]

With his permission, I'm republishing his blog here. Thank you to Dimitris for his excellent content! Please visit his original blog post as […]

Do you really need to scale to zero?

In the FaaS space, there has been a big push to allow the ability to scale down to no workload running. I want to ask: Is this something you actually want or need? Scaling to zero allows containers to be run only when there is demand. For certain workloads, this gives a lot lower […]

How Big is a Container, Really?

One of the first questions in any discussion about cluster sizing tends to be “How many containers are you running?”. While this is a good data point (especially if you are pushing the scheduler to its limit) it doesn’t show the whole story. We tend to abstract out a container as […]

Six First Impressions of SUSE Cloud Application Platform

While I’ve been developing for Kubernetes for a few years now, I am pretty new to both SUSE and Cloud Foundry. I’ve got to say that both have been great experiences! SUSE is a fantastic place to work and our Cloud Foundry distribution (SUSE Cloud Application Platform) makes my development life easier. &[…]

You may not know it, but you already have a PaaS

I read a blog recently (that I sadly can’t find again) about how important it is to use a Platform as a Service (PaaS). It made the argument that everyone running at any sort of scale has had to solve the same basic problems. This got me thinking about how every company doing software […]

In this blog, I will dig into what a container runtime is and how CRI-o differentiates architecturally from Docker. I’ll also dig into how the Container Runtime Interface (CRI) and the two Open Container Initiative (OCI) […]
