o Cloud computing makes server computing a commodity.
o Regards all users as consumers instead as specialists.o No fixed format for xAAS, no interop, non-comparable.o Comparable with SMS over GSM networks.o Marviq is a real-world to cloud integrator helps you
taking one step at a time.
You can start NOW and benefit.
Cloud Computing Now
• Cost reduction. • Flexibility.
‘Traditional IT’ is not up to web-speed.• Simple SLA without much restrictions• Usage based cost model• Scaling up to X times the current load• Less maintenance, less visible technology• Open standards• Easy to control and maintain
Requirements for Cloud
Essent Online
o www.essent.nl is the website for over 2.5 mln customers for their selfservice. Traffic is ofter triggered by energy related news.
o Currently 1/5 of the customers has an online account. End 2009 this should be 50% and growing.
Campaign InfrastructureContent Delivery and the website
Move out the campaigns• Several small campaigns are started and images
are invoked for $80/month• A campaign should not be punished for their
success. Usage based pricing makes calculation comparable to marketing on other channels.
• Several images run on EC2, but also Google AppEngine and other platforms are under consideration.
The ability to execute directly on several online platforms cheaply and quick has given
an impulse to online campaigns.

Campaign site
Phase 1: Static content & CDN
• Static and binary data stored on Simple Storage Service (S3) to be retrieved using http
• 24 hour caching on Internet a lot of caching servers CloudFront
• http://www.essent.nl -> http://static.essent.nl
What are the benefits?• Loading performance is better• Storing equals backup (3 times)• Easy to manage from
everywhere• Can be rolled out transparently• SLA level 99,9%• No web servers !!!

Phase 2: Publish all content outside
• Move the content of the website externally from the content management solution.
• Pages are placed externally as static HTML together with images.
• Standard Tridion publishing to Amazon cloud connector.
• Mechanism to circumvent the 24-hour cache CloudFront by renaming data instead of updating it.
Phase 3: Full production
• Configure virtual servers on Elastic Compute Cloud (EC2) where needed
• Design robust architecture AWS (EC2, S3 and CloudFront) and Tridion
• Proof of Concept environment• Minimalize e-Platform in-house
What are the benefits?• Lower opex• Optimal bandwidth usage• Website is highly available• SLA level of 99,95%• No need for ‘web server management’

Build to change vs. Design to last
• Build to change:– Agile development and deployment– Quick incorporation of new
presentation standards
• Design to last– Fixed interfaces,
comprehensive definitions– Focused on the process– 40/30/20/10% rule applies

• Peak in usage between 08:00 and 11:00.• Reporting engine should run on-demand• Multi-tenant because in use by multiple
insurance and ‘ARBO’ companies.
