Here’s why you should use containers

crane-lifting-container-in-the-clouda

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 […]

Docker embraces Kubernetes with Docker Enterprise 2.0

two-flowers-beneath-clouds

It turns out Docker was serious about adopting Kubernetes. Docker has its own container orchestration program, Docker Swarm mode, but the company saw the wind was blowing towards Kubernetes so it added Kubernetes to its selection of orchestration tools in October 2017. But, there’s adoption and then there’s “Adoption.” With the first you announce you’ll […]

What are cloud regions and availability zones?

earth-at-night

If you use a public cloud, you’ve used availability zones (AZ), but what are they really? How do they fit into regions anyway? Let’s go over the basics. First, a region is not an AZ. No, I know what you’ve been told, but it’s not. A region must have at least one AZ within it, […]

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 […]

Is the end of the traditional data center in sight?

dead-end-sign

We all know that the cloud is growing at the expense of server rooms and data centers. But Cisco predicts in its Cisco Global Cloud Index that by 2021 “hyperscale data centers” will represent 53 percent of all installed data center servers. For hyperscale, read cloud data centers and you see the future as Cisco sees […]

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 […]

Kubernetes is the number one container orchestration program, but still faces challenges

leap

Kubernetes is the top cloud container orchestration program, but that doesn’t mean it’s home free. A Platform 9 survey at the most recent KubeCon in Austin identified both strong and weak points for the program. First, the good news: Kubernetes is gaining new users and developers rapidly. KubeCon attendance grew 400% from 2016 to 2017. […]
