Building a European Cloud

Mittwoch, 16. Oktober 13

European Cloud?


Hungarian Cloud?


Budapest Cloud?


Your personal Cloud??


The cloud is about sharing.


Spare capacity,Virtualization,

Share spare capacityPay as you go


So why not share globally?


Privacy


Any transfer of personal data of EU citizen to a non-EU

state with a lower data privacy level compared to EU

standards is prohibited.- Directive 95/46/EC


EU Safe Harbor


• is a EU directive

• regulates the processing of personal data within the European Union


U.S. - EU Safe Harbor


• Self(!)-certification process

• = swear to the United States Department of Commerce to comply to EU privacy laws


A memo from the EU commision:


"The Safe Harbour agreement may not be so safe after all."

Safe Harbor


Where security meets freedom


The story oflavabit.com


• Encrypted email service (*2004) by Ladar Levison

• Used by Edward Snowden

• Ordered to turn over its SSL private key


Levison's was put to the decision: shutdown or “become complicit in

crimes against the American people”.


Lavabit.com was shut down on August 8, 2013


"This experience has taught me one very important lesson: without

congressional action or a strong judicial precedent, I would strongly

recommend against anyone trusting their private data to a company with

physical ties to the United States".- Ladar Levison, Lavabit.com


• It's not about having data on European servers

• It's not about having a European company


It‘s aboutstaying completely off any US provider and don‘t tie

to the US in person or with your company.


Relying on open source software is a good choice, too.

Cloud Foundry


• CF = large distributed system

• Inner shell vs. outer shell

• Bosh = Bosh outer shell > deploy CF

• Offers the CF API endpoint

• System authority for issuing commands

• Start apps

• Create service

• Binding services
