AWS as a Business Strategy Strategic: On-Demand Capacity : Absorb users or data and scale smoothly, integrate with larger players without trailing behind Operational Noise Reduction : Allows management to focus on building the company and the product Complete data center outsourcing : Allocate our resources to develop intellectual property and relevant, proprietary knowledge Tactical: The world’s best data center at $70 per machine per month: Reduce the cost of a NOC staff ($300K), equipment ($100), redundancy ($50K) No fixed cost and total variable cost : Adjust hosting cost to business performance, reduce the up-front cost of preparing for growth Endless storage: guaranteed storage scaling, backup and redundancy. Reduce bandwidth bottlenecks by serving media from S3

SOA on AWS? Geek fest! The problem: process large data feeds for thousands sellers, and millions of listings (did we mention images?) The ingredients: S3, EC2, SQS and Java (Spring) The solution: Proxy the call to a delegate service bean, implementing your business interface (keeps the code clean) Let the proxy ship the method call to SQS, along with a reference to the arguments, store argument objects in S3 Run your [backend] app servers on EC2, define SQS listeners to pick up the call, locate the local business service, get the arguments and invoke A scaleable SOA solution in 50 lines of code!

The solution:

Proxy the call to a delegate service bean, implementing your business interface (keeps the code clean)

Let the proxy ship the method call to SQS, along with a reference to the arguments, store argument objects in S3

Run your [backend] app servers on EC2,

define SQS listeners to pick up the call,
