“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”
Clearing the air on cloud computingMarch 2009, McKinsey & Company

Uses less fuel
Costs less to operate
People don’t crash them intentionally
Is much safer
Much cheaper
Not as noisy

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
![Page 10: McKinsey got it wrong!](https://reader036.vdocuments.site/reader036/viewer/2022081413/5473ba9eb4af9fbe0a8b5573/html5/thumbnails/10.jpg)

#2 Don’tsAvoid legacy apps with extremely high IOPS Not fast enough Is going to be resolved
in the near future though
![Page 11: McKinsey got it wrong!](https://reader036.vdocuments.site/reader036/viewer/2022081413/5473ba9eb4af9fbe0a8b5573/html5/thumbnails/11.jpg)

#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
David Stott Building, Detroit,133m high, 32 floors, built in bricks!!!

#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
![Page 13: McKinsey got it wrong!](https://reader036.vdocuments.site/reader036/viewer/2022081413/5473ba9eb4af9fbe0a8b5573/html5/thumbnails/13.jpg)

#5 Do’sUse tools like
Intelligent Load Balancers
Queuing Memcache Hadoop New style databases Write your own monitor

#6 Do’s Use a platform that helps to scale
RightScale GigaSpaces Microsoft Azure
![Page 15: McKinsey got it wrong!](https://reader036.vdocuments.site/reader036/viewer/2022081413/5473ba9eb4af9fbe0a8b5573/html5/thumbnails/15.jpg)

#7 Do’sMake use of the flexibility you have
Create skeleton infrastructures
Dynamically provision when load occurs
Decommission when not needed anymore
