Presentation that I used in my recent visit to College of Technology, Pantnagar

1. - Jainendra Kumar (Jai)
Head of Products and Technology

2. It is much more that writing code.
It is an act of applying a
collection of techniques,
methodologies, and tools that
help with the production of a
high quality software system,
within a given budget, before a
given deadline, while change
occurs.

3. Techniques (Methods)
Formal procedure for
producing results using some
well-defined notion
Methodologies
Collection of techniques
applied across software
development and unified by a
philosophical approach
Tools
 Instrument or automated
systems to accomplish a
technique

4. It is a multi-disciplinary discipline
A blend of many older science
& engineering disciplines and
new ones

11. • The quality and
longevity of a
software-reliant
system is largely
determined by its
architecture
• Architecture is of
enduring importance
because it is the right
abstraction for
performing ongoing
analyses throughout a
system’s lifetime.

13. • Increased connectivity
• Scale and complexity
• decentralization and distribution
• Big data
• increased operational tempo
• inter-reliant ecosystems
• vulnerability
• collective action
• Disruptive and emerging
technologies
•

16. • Cloud computing is Internet-based computing, whereby
shared resources, software and information are provided to
computers and other devices on-demand, like the electricity
grid.
• The cloud computing is a culmination of numerous attempts
at large scale computing with seamless access to virtually
limitless resources.
• on-demand computing,
• utility computing,
• ubiquitous computing,
• autonomic computing,
• platform computing,
• edge computing,
• elastic computing,
• grid computing,

17. • Business viewpoint
• Reduce IT cost
• Improvement in time to market
• Pay as you go (variable cost over fixed investment)
• Reduce IT dependency
• Work from anywhere
• Competitiveness
• Process efficiency

Description
Services – Complete business services such as
PayPal, OpenID, OAuth, Google Maps, Alexa
Services
Application
Focused
Infrastructure
Focused
Application – Cloud based software that eliminates
the need for local installation such as Google Apps,
Microsoft Online
Storage – Data storage or cloud based NAS such
as CTERA, iDisk, CloudNAS
Development – Software development platforms used
to build custom cloud based applications (PAAS &
SAAS) such as SalesForce
Platform – Cloud based platforms, typically provided
using virtualization, such as Amazon ECC, Sun Grid
Hosting – Physical data centers such as those run
by IBM, HP, NaviSite, etc.

25. • Multi touch - double taps, pinch-spread, and other
compound UI gestures
• Fast graphics API - the native platform gives you the
fastest graphics, which may not be a big deal if you’re
showing a static screen with only a few elements, or a very
big deal if you’re using a lot of data and require a fast
refresh.
• Fluid animation - related to the fast graphics API is the
ability to have fluid animation. This is especially important in
gaming, highly interactive reporting, or intensely
computational algorithms for transforming photos and
sounds.
• Built-in components - The camera, address book,
geolocation, and other features native to the device can be
seamlessly integrated into mobile apps. Another important
built-in components is encrypted storage, but more about
that later.
• Ease of use - The native platform is what people are
accustomed to, and so when you add that familiarity with all
of the native features they expect, you have an app that’s
just plain easier to use.

26. • An HTML5 mobile app is basically a web page, or series
of web pages, that are designed to work on a tiny
screen. As such, HTML5 apps are device agnostic and
can be opened with any modern mobile browser.
• HTML5 apps are easier to develop, easier to support,
and can reach the widest range of devices
• Users won’t have the familiarity of the native look and
feel, or be able to use compound gestures they are
familiar with.
• significant limitations, especially for enterprise mobile,
are offline storage and security.
