The document discusses recent trends in the IT industry including cloud computing, mobile applications, Agile methodology (Scrum), N-tier architecture, and Java vs .NET. It covers topics such as cloud computing fundamentals and features, social networking sites, mobile app development and monetization, the shift from waterfall to Agile development, Scrum processes, Agile principles, N-tier architecture, advantages of both Java and .NET, and the continued relevance of object-oriented design.

1. Latest Trends
in the
IT Industry

2. Cloud Computing
Mobile Applications
AGILE Methodology – SCRUM
N-tier architecture
Java vs .NET
 Object Oriented Design and its Relevance

3. Cloud Computing Fundamentals
• Cloud computing provides computation, software,
data access, and storage services that do not require
end-user knowledge of the physical location and
configuration of the system that delivers the services.
• The Power Grid example

4. Cloud Computing – 5 salient features
1. Dynamic Computing Infrastructure
2. IT Service Centric approach
3. Self Service based usage model
4. Minimally or Self Managed platform
5. Consumption based billing
** PROVISIONING **

5. The CLOUD Architecture

6. Cloud Computing

7. Social Networking Sites

8. Social Networking – already on Cloud

9. Mobile Applications
What is a mobile app?
perioperative patient tracker example …
how many of us have a mobile phone here?
can you pay the electricity bill using your mobile phone?
How do you/a company make money from mobile apps?
• Sell it through a mobile app store / network
• Ad inside the app - can monetize everytime the user runs
the application / plays the game
• Question !
• What location or where inside the application should an Ad
be placed to get maximum returns?

10. Mobile Applications

13. Waterfall
to
AGILE

14. SDLC – Software Development Life
Cycle

15. SDLC and the Development Models
• Waterfall model (traditional)
• AGILE development methodology (fairly new)

16. Success Rate of
IT Projects?

18. Agile Development Methodology
 Iterative Development
 user stories further divided into tasks
 Product Backlog, Sprint Backlog
 Continuous Integration
 TFS or Cruise Control
 Unit Tests + TDD (Test Driven Development)
 Pair Programming
 Spike Solutions
 Merciless Refactoring
 The Daily Standup meeting (5 minutes / developer)
 What has been done after the last stand up meeting?
 What will you be doing till the next standup meeting?
 Any bottlenecks?
 The Sprint Burndown chart

19. AGILE - Scrum Process

21. Agile Principles
1. Satisfy the Customer
2. Welcome Change
3. Deliver Frequently
4. Work as a Team
5. Motivate People
6. Communicate Face-to-Face
7. Measure Working Software
8. Maintain Constant Pace
9. Excel at Quality
10. Keep it Simple
11. Evolve Designs
12. Reflect Regularly

22. Sprint
Task Board

23. Sprint Burn Down

24. Release Planning
Plan features in sprints and releases
Releases depend on accepted sprints

25. N-tier architecture
* N-tier Vs N-layer ?
3-layer architecture

26. True N-Layer Architecture Example
Media Server – CDN based
Media Server – CDN based
Media Server – CDNCDN
Media Servers – based
based
CDN: content delivery networks
3rd Party Web Services
* Akamai
* Amazon
* Reliance Globalcom

27. Why Java?
 Development and runtime - both platform independent
 Better standards compliance
 Open Source language that further depends on other open
source vendors for its IDE, Web Server, App Server, etc.
 Claimed to be more secure than .NET code
** Name a programming construct avilable in Java, but not in .NET?

28. Why .NET?
 Fast turn around time
 Single Framework handles everything – no need for multiple
frameworks from different vendors for different functionalities.
 Much better funded so that newer features are coming out at
the fastest pace. LINQ, AJAX, Performance Profiler, Unit
Testing Framework, Client side Reporting and a lot more
integrated into one platform
 Language independent – C#, VB.NET, C++ developers can all
work together on the same project
 Simpler AJAX implementation
** Is .NET free?

29. Java, .NET  Object Oriented
 Most of what can be done using Java can be done using .NET
and vice-versa
 Java as well as.NET languages like C#, VB.NET, etc are all
Object Oriented
 Object Oriented Design has been steady for the past 30 years or
so and has changed very little.
 Case in Point: Most, if not all of the design patterns published
by the GoF(Gang of Four) in 1994 are still the back bone of
current OOPs design (Singleton, Strategy, State, Factory etc.)

30. Object Oriented Design – most important
 Class
 Object
 Encapsulation
 Inheritance
 Polymorphism
 Overloading
 Overriding
 UML (Unified Modeling Language)
 Association
 Aggregation
 Composition
 Class diagrams, sequence diagrams, … more.
 Abstract Class
 Interface

31. Domain Areas
Web
Security Windows
Network Mobile
Smart
Client

32. Discover Your Passion!
 What area in IT interests you the most?
 Writing business logic code? – focus on OOPs, design patterns, … etc
 Creating beautiful interfaces? – focus on design tools like Expression
Blend
 Application performance? – focus on optimization tools like VS2010
Profiler, DotTrace, Ants Trace
 Application Testing – ( relative cost of a bug in production vs a bug
caught during development )
 Data storage/retrieval ? focus on DB administration / development
 Network administration – security/firewalls/login/domains/ADs/….
 ERP software and tools (SAP, Peoplesoft, Oracle, BAAN, …)
 Web vs. Windows vs. Smart Client Apps vs. Mobile apps

33. True Story of a Young Boy
Moral of the Story….
 You have to figure out your passion
 Finding a mentor to guide you and assist you –
someone who has the right experience
 Having a plan – plan your next 10 years
 Do your best and not compare with anyone else
