TOGAF has a method called the ADM (Architectural Development Method), the good news is that the same method applies to defining any Architecture (including setting up the Architecture Practice itself).
The ADM breaks down into phases that are run iteratively (not always in a set sequence). So lets get started with Phase A:
Phase A – Setting [...]
TOGAF breaks down Architecture into the following pillars:
Business Architecture
Application and Data Architecture
Technology Architecture
Phase B on our quest to establish an EA practice focuses on Business Architecture:
Terminology: Define a set of standards so that everyone is talking consistent language (formal term here is Ontology)
Process: The ADM (architectural development method) is open to be tuned to suit [...]
TOGAF uses a term “Enterprise Continuum” and I wish they would think of a different phrase as it throws me each time. It’s important we know exactly what it is as it’s the key deliverable for Phase C.
It relates to three elements:
Architecture Continuum
Solutions Continuum
Architecture Repository
Consider the repository as a folder full of documents, the usual [...]
The good news is that most of the legwork to get the ball rolling is done in phases A to C. Here is what is left:
Phase D: Define the technology that is used within the EA practice, ideally a TOGAF aware repository. If nothing else set standards for people to follow; for example always create [...]
Let’s start by establishing what does an EA practice do for your organisation. The EA practice should identify
Where are you?
Where do you want to be?
How do you get there?
The reason the methodology is so important is that all three of these answers are always changing. The wind of change blows in for a huge array [...]
I believe the first rule of drawing comparisons is to compare apples with apples. As I mentioned in an earlier blog Vsphere is a group of products, Hyper-V is a capability of one product – namely Windows 2008.
So let’s start with VMware ESX v Windows Server 2008 Hyper-V
I see a lot of HyperVisor experts jumping [...]
For those not into Nuclear Physics; Half Life is defined as the amount of time for the atoms in a radioactive substance to decay to half the level they started with.
The IT Industry may enjoy a minor boom once the effects of the global recession diminish but ultimately I suspect we are heading for a [...]
Most people see digital certificates as a black art with layers of complexity. Having designed and deployed a Public Key Infrastructure for an Investment Bank I will try and convey the simplicity and risks.
A Digital Certificate has two parts, a public and private key. The public key can lock your door but only the private [...]
I see Commercials and Capability progressing a lot faster than the ability to tackle Compliance. What’s more some of the issues faced here are related to people perceptions and they are not easily fixed with technology alone.
Take a SaaS example in Google Mail. Its low cost and highly capable (ok a few more bells and [...]
It’s been many a year since I studied PRINCE2, since then I have experienced rather too many project managers keen to maintain plans with clearly unmanageable numbers of activities and dependencies.
I am a strong believer in the art of the practical. Some programmes may impose a structure but to me the layering as proposed in [...]
My eye starts twitching when I see fancy marketing terminology, so I have taken a slightly overdue relook at the VMware stack.
And stack is the first answer to my question, VSphere is essentially a stack of software, mostly updated versions of existing VMware products but some new and worthy of attention.
ESX and ESXi: ESX(i) is [...]
