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
5. COSTS USING TRADITIONAL HOSTS
Base Annual Depreciation Cost $30,000
Overhead(30 hosts) $6,000

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.

8. CLOUD ADOPTION STRATEGY
Application category
• Analysis and reporting
• Business management
• Business operations
• Engineering
• Employee productivity
Organizational Change
Management
• Early Adopter
• Fast follower
• Cloud skeptic
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.
12. APPENDIX
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
• “It was cheap experimentation, and the learning curve
isn't steep.” – Derrick Gottfrid, Nasdaq
Notas do Editor
Cloud Orchestration Services is a best-of-breed approach for cloud services integration that provides clients with service level management, remote monitoring, reporting, auditing and data transparency
Cloud Software as a Service (SaaS). The capability provided to the to use the provider’s applications running on a cloud infrastructure and accessible from various client devices through a thin client interface such consumer is as a Web browser (e.g., web-based email). The consumer does not manage or control the underlying cloud infrastructure, network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.
Cloud Platform as a Service (PaaS). The capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created applications using programming languages and tools supported by the provider (e.g., java, python, .Net). The consumer does not manage or control the underlying cloud infrastructure, network, servers, operating systems, or storage, but the consumer has control over the deployed applications and possibly application hosting environment configurations. Google App Engine, Microsoft Azure Services
Cloud Infrastructure as a Service (IaaS). The capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly select networking components (e.g., firewalls, load balancers).
Reserved Instances give you the option to make a low, one-time payment for each instance you want to reserve and in turn receive a significant discount on the hourly usage charge for that instance.
Spot Instances allow customers to bid on unused Amazon EC2 capacity and run those instances for as long as their bid exceeds the current Spot Price. The Spot Price changes periodically based on supply and demand, and customers whose bids meet or exceed it gain access to the available Spot Instances.
