Creative Chaos Personal Networks Fun and Work

How the Web Got Started

Everyone Could Publish

The “Oh YEAH! Button”,

Everyone Could Share,

Ease of Use

Everyone Started Programming

Remember CGIs?

Remember Stateless?

Services Were Born…

Enterprise IT Ignored the Web

The Media Industry Laughed,

The Music Industry Bickered

And Everyone Else?

How the Web Grew Up

Commerce Discovered the Web and Enterprise IT Moved in

Methodology Adapted

1st Enterprise Joined Chaos

2nd Procedures Appeared

3rd Standardization Began

Everything Enterprise Was Politicised

Open Source Became Commercial,

Law Makers Had and Have

No Sense for the Web

Client Server Could Not Kill the Host, ... the Web Killed Client Server

Celebrated as Victory for Web

Development Processes Followed Corporate Needs

Corporate != Good Business

Technology Met Mainstream

Need to Scale Developers,

Standardization Required,

Management Needed,

Cool Time for Taming and Commercializing Geeks

HOLD ON – the High Tech Guys Were Different

Google – Driven by Engineers

Then Consumers Conquered the Web

WiKiPediaCroud-Sourcing Kills the Establishment

Inconsistent and Failing

The World Does Not Have Two Phase Commit, Why Should Software?

And Did You Ever Notice? Things Break Down!

BIG

Enterprises Used to FeelSo Important About Data

But the Biggest Bank’s IT Would Not Fill Half of One Google DC

Enterprise IT Never Heard the Bang

Command and Control vs.

Community

ESB and SOA vs.

API and Protocol

Waterfall vs.

Agile Project Management

It‘s the End of the Web as We Know It

How to Actually Web TODAY!

Be Scalable From the Start

Be Scalable – Be Parallel

Functional, Distributed,

You Actually Have to Think

Be Scalable – Forget Sessions

EVERY REQUEST IN LOAD BALANCED, NOT JUST EVERY USER…

Plan For Failure –It Must NEVER Destroy the UX

Plan For Failure In Your Application

Reentrant,

Distributed Persistency,

Build a Security Model

“Print Stuff”

Plan For Failure In API Calls You Use

You Do No Longer Control the Components You Use, So You Have to Deal With Their Potential Unavailability

Plan For Failure In Infrastructure

Load Balancing Is NOT Optional

It Is Not an Amazon Failure If There’s Just One Server

Think In and Write APIs

Services Are Old School

Even Stacks Can Impair

Think in APIs, Because Everyone Should Use You

HBase+ Hadoop
