What is Helm? A look at software package management for Kubernetes

what is helm

So, you’re using Kubernetes to manage your cloud’s containers. Good for you for jumping on the Kubernetes bandwagon.  But, how do you load programs into those containers in the first place? There are several answers, but the one which has the blessing of the Cloud Native Computing Foundation, the parent organization of Kubernetes, is Helm. […]

A very brief history of cloud computing

cloud history

You can argue over when cloud computing really began, but one good starting point is 2006 when then Google CEO Eric Schmidt said at a conference: “I don’t think people have really understood how big this opportunity really is. It starts with the premise that the data services and architecture should be on servers. We call […]

Why you don’t want to run a roll-your-own cloud

running your own cloud

Thanks to my job, I have accounts on many public clouds. I also have production private clouds — open-source OpenStack and NextCloud spring to mind. But, but, as someone who cut his teeth on Unix system administration back in the 80s, I also run my own smaller private clouds using a homebrew of programs. Self-hosting […]

What is AWS Outposts? AWS in your house.

Outposts concept

The public cloud is great, but there are still some jobs you need to keep close to home. That’s why hybrid clouds, where you use both the public and private clouds to get your work done, are so popular. Lately, most of our attention has been focused on using Kubernetes container orchestration. But, for all […]

Bringing a bang to your serverless processes: Firecracker

New Years Eve fireworks

Amazon Web Services (AWS) Lambda‘s growing popularity is proof positive that serverless computing is for real. But wouldn’t it be nice if you had a better view of how Lamba’s function-as-a-service actually works? Or, better still, if Lambda’s inner workers were open-sourced so you could use them in your own serverless projects? Guess what? AWS […]

Things to consider before spending on multi-cloud

clouds reflected

The concept of multi-cloud is simple. You’re running multiple business processes using more than one cloud. This isn’t the same thing as hybrid cloud. With that model, you’re coordinating business processes across multiple clouds.  So, for example, if your office program is Office 365, but you’re running line of business programs on Amazon Web Services, […]

2019’s top five cloud stories

top 5 cloud stories

The cloud keeps getting bigger and ever more important to IT — from the smallest business operating out of a closet powered by Office 365 or Google Docs to Fortune 500 companies running international, multi-cloud operations. Here’s what that growth looked like in 2019: 1. The public cloud continues to grow larger The public cloud […]

Untangling the service mesh

service-mesh-metaphor

You may have noticed that, as you run more and more applications in containers it’s not easy to get them to talk and play well with each other. That’s because instead of monolithic applications using APIs to talk to components on one machine, we now have one app here, another there and they use networking […]

What is multi-cloud anyway and why do we use it?

multi-cloud-visualization

Many companies are moving to multi-cloud deployments. For example, most EMEA and North American financial services businesses are moving to multi-clouds within the next two years. Gartner reports 81 percent of surveyed public cloud users are already working with multi-clouds. But, Gartner states that multi-cloud is a subset of hybrid clouds. I disagree. In a […]

Kubernetes’s explosive growth has come with attention paid to security and stability

growth-concept

You may have noticed I write a lot about Kubernetes, the Cloud Native Computing Foundation (CNCF) sponsored open-source container orchestration program. That’s because I have no choice in the matter. Just like Docker turned containers into the way to run server applications, Kubernetes quickly overcame its rivals and became the way to manage containers.  Practically […]
