If there was a school of

IT ARCHITECTUREwhat would I learn there?

Can there be great craft without

ARTISTRYand great art without

CRAFTSMANSHIP?

HISTORYof IT Architecture

Studying history is the shortest path to

WISDOM

Architecture is the only property of interest

when reviewing

ANCIENT applications or systems

IT ARCHEOLOGYThe study of composition or

functional details aboutan extinct IT system

Historically, architectural endeavors express the

ZEITGEIST(the spirit of an age)

ANCIENT ERAAcceptance of myth-

based truths, driven by magic and wizardry

RAWREFINED

CLASSICAL ERARuling of order,

symmetry, frameworks and reasoning

MEDIEVAL ERADominance of religion, dogmas and canons of

scripture

RENAISSANCE ERAEmbracement of art, beauty and crowd-pleasing aesthetics

REALSIMULATED

MODERN ERAInclination to relativity

and scientific methods of revealing the truth

ARCHITECTSversus

ENGINEERS

An engineer knows

EVERYTHINGabout

ONE THING

An architect knows

SOMETHINGabout

EVERYTHING

Who is asking

HOW?And who is asking

WHY?

UNEXPECTED

HABITUAL

Structural problems are different from problems

of

EXISTENCE

It is nicer to join

THE PIRATESthan to join the navy

Who is the mainENEMYof IT Architecture?

Are ENGINEERSthe primeval evil as

they don’t understand architecture?

NO, WE NEED BOTH!Architects have head in

the cloudEngineers keep feet on

the ground

ARCHVILLAINof architecture are stencils, templates, guidances and

scaffoldings!

Stencils and templates

PREVENTmistakes and disasters,

and lower the risk of failure

But what they assure in its place is

MEDIOCRITY

It is not just what you don’t know that

HURTS YOUIt is what you know that

JUST AIN’T SO.

Stencils and templatesspare you from

THINKING

Templates are not evil, they are just frequently

MISUSEDresulting in mediocre solutions

RISKYSAFE

The problem is not that we

AIM TOO HIGHand fail, but that we aim too

low and

S U C C E E D

Multiplicity of possibilities can

drag the uneducated into

COMPLEXITY

Trying to solve every problem results in

GENERICsolutions that solve no

problems at all

The key is in

SIMPLICITYand

SPECIFICITY

SIMPLECOMPLICATED

STRATEGYSeriously, why would architects care about it?

Without a strategy,

ARCHITECTUREcan take you there.

ANY

STRATEGY is profoundlydifferent from

TA C T I C S

Tactical questions:

HOW?Strategic questions:

WHY?

HOW does it work?

HOW is it implemented?

HOW do I put it apart?

WHY is this needed?

WHY do they want it?

WHY are they satisfied?
