Learn Docker Swarm – Native Docker Clustering

So continuing my work around Docker and Linux containers, a week or two ago I published another Docker related course on Pluralsight.  This one’s titled “First Look: Native Docker Clustering“….. The title kind of gives it away – it’ll get viewers up to speed with running a small clustered Docker infrastructure using Docker Swarm.  Now… Read More »

Here come the *real* server Operating Systems…

The days of server and desktop Operating Systems looking and feeling the same are gone – those are the olden days! We’re being invaded by a new breed of *proper* server Operating Systems.  These guys are stripped down, hardened, tuned and optimised for server workloads. They’ve got none of the extra crap needed for things… Read More »

Quick Question on VSAN vs XtremIO Architectures

This is just a really quick one…… I noticed that upgrading an existing VSAN to the newly announced VSAN 6.0 is a non-disruptive rolling upgrade. Fair enough, so it should be right? Well…… part of the upgrade requires what sounds like a fairly significant underlying on-disk layout change.  Basically, the upgrade to VSAN 6.0 updates… Read More »

Docker on Windows – Some Insight

So last week I had a cracking and informative conversation on Twitter about native Docker support on the next version of Windows Server. So I thought it only right to scribble down the good stuff here for anyone who didn’t get a chance to listen in and get involved. It all started when Stu Miniman… Read More »

ESXi vs Hyper-V – Could Docker Support Be Significant

Thinking out loud here…. Did VMware shoot themselves in the foot ditching Linux? I remember wondering a while back whether VMware had shot themselves in the foot by ditching Linux and open source in favour of a proprietary kernel which allowed them to keep everything to themselves. Let’s not forget, when they did this, there… Read More »

Want to Learn Docker – LOOK NO FURTHER!

There’s no arguing about it…. Docker is a hot trending technology and looks set to have a dazzling future. And it’s my personal opinion that it could be the next VMware. With the above in mind, there’s no time like now to skill yourself up so that you can take part in the container revolution.… Read More »

Stop Hiding the Negatives!

I was asked to comment on Chad Sakac’s post about not trusting people who *go negative*.  Basically Chad is telling us not to trust anyone that says negative stuff about a technology.  Frankly I think that notion is dangerous and absurd! NOTE:  I’ve no beef with EMC, XtremIO here. I just think what Chad is… Read More »

A Container First Approach

It seems like everyone I speak to about Docker containers thinks they can’t replace virtual machines. Well…….. I beg to differ! I thought containers could only run a single process? First up. Why do people think containers can’t replace VM’s? Well…. from my extensive scientific research (a.k.a my gut-feel after conversations with various people) it… Read More »

CoreOS Fires a Rocket Up Docker’s ****

Quickly setting the scene……. Containers are rocking the IT world. I think they’re the next generation of virtualisation technology. And I think in time they’ll supersede the virtual machine as the dominant runtime environment for applications. And Docker is emerging as the de facto standard in this new world of containers. And that’s all well and good.… Read More »

Nimble Storage – Heir to the Throne of the SME?

I’m seriously thinking the recent announcement that Nimble Storage will support Fibre Channel might herald the birth of a new major primary storage player. And I seriously mean a major player… right up there with EMC, NetApp, HDS, HP… How come? Isn’t the FC market flat? Well, may be. But it’s still a huge-old market.… Read More »
