McKinsey got it wrong!!

“A typical bare-metal Windows server configuration is 144% cheaper than EC2!”

“The cost of cloud must come down significantly for outsourcing a complete data centre to make economic sense”

A Smart car is much better than an F1 because ...

08/04/2023 CloudCamp Scotland September 2009 4

Uses less fuel

Costs less to operate

People don’t crash them intentionally

Is much safer

Much cheaper

Not as noisy

...mhhh so what is wrong then?

The report has a few BIG flaws:

1. Simply ignores to quantify the value of agility, speed, flexibility, scalability, pay-as-you-go

2. Has a legacy app point of view

3. Pricing wrong – ok, my view!

So, how can YOU benefit from the Cloud then?

#1 Don’tsAvoid large-memory single-instance apps Expensive Not enough CPU

horsepower

08/04/2023 CloudCamp Scotland September 2009 10

#2 Don’tsAvoid legacy apps with extremely high IOPS Not fast enough Is going to be resolved

in the near future though

#3 Do’sStart thinking in small ‘bricks’ no specialised HW for each

project anymore!!! start to standardise

building blocks – CPU & storage

use the small granularity to your advantage

#4 Do’sInvest only in modular, multi-tier, horizontally scalable apps Web Apps you can load

balance Apps with clear separation of

front-end, application & database

Service Oriented Architectures (SOAs) generally are suitable

08/04/2023 CloudCamp Scotland September 2009 13

#5 Do’sUse tools like

Intelligent Load Balancers

Queuing Memcache Hadoop New style databases Write your own monitor

08/04/2023 CloudCamp Scotland September 2009 14

#6 Do’s Use a platform that helps to scale

RightScale GigaSpaces Microsoft Azure

08/04/2023 CloudCamp Scotland September 2009 15

#7 Do’sMake use of the flexibility you have

Create skeleton infrastructures

Dynamically provision when load occurs

Decommission when not needed anymore
