Design to Leverage
“Give me a lever long enough and a fulcrum on which to place it, and I shall move the world” – Archimedes
• Understand your environment• Identify the contention areas• Modularize & define the interconnects
– Loose coupling for flexibility
• N-tier design & code distribution– Scalability
• Structure your data• Create your own framework that leverages the
infrastructure to your application needs
