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 […]
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 […]
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, […]
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 […]
Over the last few years the way you moved applications from your data center to the cloud was lift-and-shift, refactor, or migrate to containers. The latter has gotten a kick in the pants as cloud-native techniques such as serverless computing and microservices have joined forces with containers. Still unsure what I’m talking about? Chris Aniszczyk, […]
If you ask people what their biggest concern is about containers, it’s always security. Some 94 percent of IT professionals in the Enterprise Strategy Group (ESG)‘s 2017 Cloud Security Report worry about container security. Specifically, they’re concerned that we don’t have mature container security programs. There’s truth to those concerns. After talking with people at […]
Kubernetes rules cloud-container orchestration. We all know that. You may also know that Google created Kubernetes and then spun the project’s management off to the Cloud Native Computing Foundation (CNCF) in 2015. But what you probably don’t know is that Google still controls all the computing resources used to manage and test Kubernetes and its […]
There’s no question we’re moving our applications to the cloud. We started with Infrastructure-as-a-Service (IaaS) for our data, and now most of us are considering Platform-as-a-Service (PaaS) for our programs. The question is, how will we move our programs to PaaS? You have three main choices: Lift-and-shift, refactor, or containers. With life-and-shift, you simply port your […]
Me encantan los contenedores. Tú también amas los contenedores. A todos nos encantan los contenedores. Pero, si alguna vez intentaste ejecutar sus programas en Microsoft Azure, tuviste un problema. No fue fácil ejecutar contenedores estilo Docker, una tecnología nativa de Linux, en Azure. Se podía hacer, pero era laborioso. Ahora, con Azure Container Instances (ACI), […]
In just a few years containers have risen from obscurity to become the way we deliver software. But just why are companies making the move? Let’s go over the basics. First and foremost, with containers you can run more application instances on a server than you can with virtual machines (VMs). By their very nature, […]
