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

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

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?
• Based on extensive research …

SDLC – Software Development Life Cycle
![Page 15: Latest trends in information technology](https://reader036.vdocument.in/reader036/viewer/2022081413/5491df15b4795956138b55ab/html5/thumbnails/15.jpg)
SDLC and the Development Models
• Waterfall model (traditional)• AGILE development methodology (fairly
new)

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

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

N-tier architecture
* N-tier Vs N-layer ?
3-layer architecture
![Page 26: Latest trends in information technology](https://reader036.vdocument.in/reader036/viewer/2022081413/5491df15b4795956138b55ab/html5/thumbnails/26.jpg)
True N-Layer Architecture Example
Media Server – CDN basedMedia Server – CDN based
Media Server – CDN basedMedia Servers – CDN based
3rd Party Web Services CDN: content delivery networks
* Akamai* Amazon* Reliance Globalcom

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?
![Page 28: Latest trends in information technology](https://reader036.vdocument.in/reader036/viewer/2022081413/5491df15b4795956138b55ab/html5/thumbnails/28.jpg)
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?
![Page 29: Latest trends in information technology](https://reader036.vdocument.in/reader036/viewer/2022081413/5491df15b4795956138b55ab/html5/thumbnails/29.jpg)
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.)
![Page 30: Latest trends in information technology](https://reader036.vdocument.in/reader036/viewer/2022081413/5491df15b4795956138b55ab/html5/thumbnails/30.jpg)
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

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
