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 […]

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 […]

Llega “Azure Container Instances”

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, […]

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 […]

Everything old is new again: Microservices

old-building-with-modern-addition

If I told you about a software architecture in which components of an application provided services to other components via a communications protocol over a network you would say it was… Well, it depends. If you got your start programming in the 90s, you’d say I just defined a Service-Oriented Architecture (SOA). But, if you’re […]

Red Hat’s system management tools join hands with its DevOps programs

figurine-handshake

For years we’ve used older system management tools such as Ivanti LANDESK, Kaseya VSA and  Dynatrace Application Monitoring. They’re still great, but as we move to the cloud, containers and continuous integration and development (CI/CD) DevOps programs such as Puppet, Chef and SaltStack have risen in importance. Red Hat, a leading business Linux distributor, has a foot […]

Meltdown and Spectre bring a world of hurt to the cloud

thunderstorm

Meltdown and Spectre represent a new class of security problem and the cloud — based as it is  on virtual machines — is uniquely vulnerable. The good news is patches are either already in place or coming soon to all major cloud platforms and server operating systems. The bad news is that your data may […]
