Avoid these five all-too-common cloud migration mistakes

avoid-mistakes-metaphor

I’m on the cloud. You’re on the cloud. We’re all on the cloud. But, as we move more and more of our IT — lock, stock, and two smoking servers — to the cloud, you should make sure you know what you’re getting into. Yes, the cloud can be a real help, but there are […]

Ignore the hysteria, Cloud Foundry is just fine

stay-calm-at-work-desk

Recently, Rishidot analyst Krishnan Subramanian proclaimed the Cloud Foundry, Platform-as-a-Service (PaaS) cloud, had met its demise as a standalone platform. Really? That’s news to me, and I cover Cloud Foundry like paint. What got Subramanian so frazzled was Cloud Foundry started offering Docker in place of its own container runtime, Garden. And at the recent […]

Bridging the gap between AWS Lambda and other clouds: TriggerMesh

bridging-the-gap

If you want to do serverless computing today chances are you’re using Amazon Web Services (AWS) Lambda. Which is fine if you’re wedded to AWS, but if you’d rather use another cloud or run a hybrid cloud, AWS-specific Lambda may not be ideal. Enter TriggerMesh Knative Lambda Sources (KLASS), which offers a way to bridge […]

Financial services are embracing multi-cloud

Multi-clouds — environments made up of multiple public and private clouds typically used for different purposes — may well be the cloud of choice for banks. That’s according to an independent report by 451 Research, ‘Multi-Cloud Fundamental to Financial Services Transformation.’ I’m not here to argue. This report, which was sponsored by Canonical — the […]

What’s the difference between containers and virtual machines?

question-mark

I was at a conference recently when I realized the person I was talking with thought that containers were just smaller versions of virtual machines (VM). Ah, no. No, they’re not. Yes, they can function in the same ways from a practical viewpoint. For example, they’re both commonly used to run server applications. How they […]

CoreDNS: The DNS for cloud-native computing

DNS

I have a t-shirt which reads, from top to bottom: “It’s not DNS. There’s no way it’s DNS. It was DNS!” As every sysadmin knows, all too many network problems boil down to a Domain Name System (DNS) blunder. That’s already annoying, but when you have to deal with a DNS headache with fast-moving containers […]

The Calico cloud

calico-cloud

You know what’s one of the real pains of cloud and container based computing? Networking. Workloads on a cloud come and go faster than you can read this story. Connecting those workloads, especially when they become even more ephemeral containers, is not easy. That’s where the open-source Software Defined Network (SDN) Calico comes in. SDN […]

The top five upcoming cloud developments

five-clouds

Strap yourself in. We’ll be going to some interesting places with the cloud in the near future. 1. Hybrid Cloud Takes Off For the longest time, the hybrid cloud didn’t really go much of anywhere. That’s because it wasn’t easy to integrate private and public clouds. Then, along came Kubernetes and everything changed. With Kubernetes, […]

Four recent trends pointing to big things ahead for the hybrid cloud

hybrid-cloud-trending-up

The cloud has fundamentally changed. We had been focusing on the rise of the public cloud, but these last several months have showed us that the hybrid cloud may yet prove to be the real cloud IT model moving forward. As evidence, consider these four recent developments: The Rise of Kubernetes Kubernetes took over as […]

The five reasons Kubernetes won the container orchestration wars

five-stars

When I first looked at Kubernetes and the other cloud container orchestration programs, I knew Kubernetes would be the winner. No, ifs, ands or buts about it. The program was clearly so much better than its competition. Today, even its rivals support it. Why? Kubernetes enables you to run clusters of containers at scale on […]
