This document discusses moving business analytics workloads to the cloud to reduce costs compared to traditional on-premise hosting. It provides an overview of cloud computing and compares the annual costs of hosting servers traditionally versus using Amazon EC2 instances. Using EC2 could save over $30,000 per year compared to owning and maintaining their own servers. The document proposes a strategy of using reserved and spot instances on AWS along with cloud bursting when needed to further reduce costs.

3. OVERVIEW
o The future of business is collaboration, and the future of
collaboration is in the cloud
o Cloud computing technology is bringing sweeping changes
to enterprise IT
 Offers a new technological, operational, and business
model approach
 Radically increases scalability, elasticity
 Dramatically reduces deployment and operational costs

6. COSTS USING CLOUD INFRASTRUCTURE
• Forecasted using High-Memory Amazon EC2 Instances at
price of 0.72 per hour
• Equivalent to 3 core servers hosted traditionally. Additional
monitoring charges might be applicable.
• Peak load forecast=(0.72*24*30)*(30/3 instances for 30K
users)
• Current user base approximated at 30K,22K,15K etc reducing
sequentially.

9. PROS - CLOUD COMPUTING OPTION
• Reduced upfront CAPEX costs.
• Significant reduction in overhead costs , cycle time for
Hardware procurement and eventual build of traditional
hosts.
• Auto Scaling for unprecedented usage increase/decrease
• With a 99.95% availability, the Amazon EC2 option would be
a reliable option to reduce costs
• With Instances in US, Europe and APAC having variable
pricing the user load can be allocated to specific regions
• Even with 2 major titles being released per year the total
cloud costs would not exceed $30K. Significant saving
compared to a traditional host.

10. PROPOSED STRATEGY
• A viable option is to use the Reserved and Spot Instances
considering that some new titles will be released annually.
The remaining portion can be done on a pay-as-you-go
model .
 Note: Reserved instances are 1/3rd the price for normal pay-as-you-
go models. Savings still more than traditional hosts with annual
commitments.
• Cloud-bursting approach to divide the work so that part of
the task could be done in the cloud if there are less number
of titles released every year.

11. Q&A
• Roundtable Q&A

o New York Times(Fortune 500 who used Amazon Cloud)
• Used EC2 and S3 to convert 15 million scanned news
articles to PDF (4TB data)
• Took 100 Linux computers 24 hours (could have taken
months on NYT computers

isn't steep.” – Derrick Gottfrid, Nasdaq
