Hybrid IT tactics and techniques

As companies embrace hybrid IT, they must address both technology and the human side of change. There are several key actions to take: Staff and train differently: As applications move from traditional platforms to the cloud, current IT staff needs to be trained and re-skilled. Companies should recruit developers adept in Agile methodologies. Siloes should […]

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 top five upcoming cloud developments

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

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 […]

OpenStack–uh Open Infrastructure? OpenDev?–remains popular

cloud-computing

If you read the OpenStack User Survey Report you’ll find OpenStack, the open-source Infrastructure-as-a-Service (IaaS) cloud, is growing ever more popular. But at the same time OpenStack‘s branding is getting a little confusing. While the IaaS cloud name remains the same, its branding is pivoting to Open Infrastructure, or is it OpenDev? Let’s start with the good […]

The virtuous circle of cloud adoption

cloud-circle

It just turned 2019 and people are still saying the cloud is “just someone else’s computers.” Excuse me, I lost sight of my keyboard because my eyes were rolling too hard. Fortunately, that antediluvian attitude is disappearing from IT departments.  What’s bringing that about, according to a recent survey (pdf) from open-source Platform-as-a-Service (PaaS) foundation Cloud […]

2019 IT trend: Enterprises will begin closing their data centers

Is the enterprise data center dying? How dead is it? Working as an IT architect for much of my life, this is a surprising question to hear from me.  In truth, the data center within a single enterprise has been yielding to leveraged, multitenant data centers for quite some time. The leverage that can be […]

What CloudStack really is and why it matters to you

cloud-stack

If you’re looking for a new open-source cloud and you search for CloudStack on Google’s first page, you’ll find CloudStack compared to OpenStack. It should not be compared to OpenStack! Yes, both started as Infrastructure as a Service (IaaS) clouds, but they quickly took very different paths. Today, OpenStack is a complex ecosystem of IaaS […]
