Cloud native: Present and future

low cloudy mist

When we started with clouds, it was all about taking existing IT structures and moving them to the cloud. Infrastructure to Infrastructure as a Service (IaaS), software to Software as a Service (SaaS), and so on. Then, as clouds matured, people started combining Linux and containers with the idea of assembling applications from container-based microservices. […]

Practical container security issues

broken-link-in-chain

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 is free of Google’s purse strings

escape-from-bird-cage

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 […]

A step beyond Cloud 101

OK, so you want to take the plunge and move your IT stack to the cloud. Good for you. But, and it’s a big but, before you make that leap, look carefully at exactly what you’re doing. For example, it’s true that moving to a cloud should–should–save you money. But, there’s no guarantee. Next, what […]

Moving applications to the cloud: Lift-and-shift, refactor, or containers

clouds-above-highway

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 […]

Powershell on Azure goes Linux

People still assume that Windows is Windows, Linux is Linux, and never the twain shall meet. Not true. Microsoft loves Linux. You’ll find the latest proof of this in Azure Cloud Shell, which is now PowerShell Core 6 in Linux. Linux? Yes, Linux. Why? Well, as Wim Coekaerts, formerly corporate vice president of Microsoft Enterprise […]

Here’s why you should use containers

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, […]

Kata Containers: A virtual machine take on running containers

containers-and-clouds

First things first. Kata Containers aren’t containers. Kata is a virtual machine (VM) for running containers. That said, Kata promises to deliver workload isolation and security with lightweight VMs, while feeling and performing like containers. Kata does this by combining the best of two earlier virtualized container open source code bases: Intel’s Clear Containers and […]

Azure container instances arrive

I love containers. You love containers. We all love containers. But, if you ever tried to run your programs on Microsoft Azure, you had a problem. It wasn’t easy to run Docker-style containers, a native Linux technology, on Azure. Oh, it could be done, but it was work. Now, with Azure Container Instances (ACI), it’s […]
