15. So how to go for “IT”

16. So how to go for “IT”

17. Deployment perspective of Design

18. Balls to Balance

• Reliability
• Scalability
• Manageability

19. So how to juggle

20. System Architecture

21. System Architecture
Good and Bad for this?

22. System Architecture
Good and Bad for this?

26. What else?

27. 1. Language doesn't scale

28. 2. Avoid ORM if possible

29. 3. Big YES to stateless

30. 4. Cache

31. 5. No topology specific coding

32. 6. No hard bounding to local file
system

33. 7. Automate application deployment

34. Take away
• Development environment should have at
least 3 system deployment
• Server must be stateless
• Data to Database only
• Catching for worthy problems only
• Right tool for right job
• Minimize complexity
• Zero downtime deployment
