Integrating Docker with Devops Automated Workflows

A few weeks ago I released a lightning fast (~1 hour) video course over at Pluralsight showing how to integrate Dockerized apps into a CI/CD automated workflow using some cool new features on Docker Hub. Docker’s hot right. And we’ll be royally shafted if we don’t bring it under the control of our existing operational processes and… Read More »

Production in the Cloud

This is my “Production in the Cloud” presentation form the recent TECHUNPLUGGED event in Amsterdam. The skinny: It’s my opinion that public cloud services such as Amazon Web Services (AWS) and Microsoft Azure are ready for many enterprise production workloads. More than most of us think. Sure…… there’ll be cases where they’re not a fit.… Read More »

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.

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?
