How do you do backup?

Since the very earliest days of computing, a major concern for systems managers has been the question of disaster recovery. Making copies of data, and getting those copies offsite, is one of the two biggest problems in ensuring that disaster recovery is possible. (The second is, of course, making sure that those copies are actually usable at recovery time.) Historically, this has been done by shipping tapes offsite. Over the past ten to twenty years, backing up across geographically disparate data centres became a realistic option. And now, the major cloud providers - Amazon, Azure, and Google...

A Management Group can be configured with permissions and policies that can be applied to govern a like set of subscriptions, similar to how Resource Groups are designed to govern Resources with a particular lifec...

For us it is the following: How do you transform from your current legacy state with people, process and technology constraints The morph of your o...

What is an Operating Model to you?

Intro Business, IT and Management press is full of terms like "digital transformation", "new ways of working", "change your operating model", "adapt" and, "new normal" but there is little on what that means in real terms or how to address these issues in a practical manner. This seems to be left to very expensive consulting organisations with lots of MBA's, who have a habit of sweeping in, trying to change everything and then walking (running) away, leaving you with a large hole in your pocket. The key to addressing the need to change these issues is having the right operating mod...

What is Software-defined Networking (SDN)?

SDN abstracts the network control from the underlying hardware. An SDN controller works as the interface between the switches and routers via southbound APIs and the applications via northbound APIs. The main advantage of SDN – and other software-defined approaches, e.g. WAN or storage – is that as it is a programmable approach an environment can be relatively quickly adjusted to changes and is open to automation and orchestration of network services. This makes SDN an enabler to cloud computing, DevOps and an agile network. Generally, the three components involved within Software-defi...

How to enable digital transformation with Docker EE

At Diaxion, we’ve recently been looking at container strategies and how containers enable digital transformation, consolidation and collaboration for IT teams. There are some great insights and exciting possibilities in the development and operations spaces, particularly with Docker Enterprise Edition (EE). Least privilege issues are an age-old problem for many business teams and are frequently associated with outages. Developers want privileged access to test and deploy, or applications require elevated access in order to function correctly, but this violates least privilege requiremen...
