Case Study – Viacom International
In early 2006 Viacom International Japan launched
[the] FLUX [platform] with video downloads and a
streaming entertainment site, combined with social
networking.

Case Study – Viacom International
• Problem Statement
– Very high user interactions/transactions
– Success is to keep users engaged
– All user interactions are costly from bandwidth
and resource point of view
– Video
streaming/uploading/downloading/processing
– High quality Images
uploading/downloading/processing

Case Study – Viacom International
• Solution
– Used Cloud IaaS to store bandwidth consuming
media resources like videos, streams & images
– Leveraged Web service interface
(Programmable infrastructure) to access
resources
– Images and videos are processed using Map
Reduce distributed processing

Case Study
A new startup US Job Portal
• Problem Statement
– Strong Search engine which can index
structured (database) as well as unstructured
data such as resumes (word/pdf)
– Very high user interactions/transactions
– Very short turnaround time
– Limited budget

Case Study
A new startup US Job Portal
• Solution
– Rails for fast development
– Attivio to index structured & unstructured data
– Used Heroku platform as a Service which
provides Rails app , HTTP cache, WebServer ,
database as one packaged platform
– Used Amazon S3 to store
documents/resumes/images

Case Study – Cloud Cache
• A US startup company Quetzall.com offerring
intra cloud computing Services
• CloudCache provides a simple and cost
effective on demand caching solution. It
enables developers to store data in an in-
memory cache for super fast access while
decreasing database hits and increasing
performance.
• Since CloudCache runs in the cloud as a
service, developers do not need to run their
own servers just for caching. It is just like
memcached, but without the maintenance.

Case Study – Cloud Cache
• Problem statement
– Cloud should have programmable interface
– Engage opensource enthusiast to spread this
service

Case Study – Cloud Cache
• Solution
– Developed PHP API (
http://code.google.com/p/cloud-cache-php/ )
• As a PEAR package
• As a PECL library
– Developed Rails API
– Developed Java API
– Developed a working example for the users with
phpgeotiles
