3. App Engine- Why?
The Surprised is very excited to unveil The Innovator
Watcher application on Google Appengine.
This slides will walk you through the API's used & quick
architecture of Innovator Watcher cloud application.
Google Appengine was selected due to the three key areas:
Scalability: Security,Reliability Java,Java & Java:
built on the same highly secure & reliable smooth transition from
scalable tools on infrastructure of Google Enterprise Application
which Google Development
Apps are built Background

4. GWT - Why?
GWTGWT Ofo Others
OTHERS
• Out Of the Box support for • Need to be adapted to the
AppEngine Appengine platform
• End to End Java • Steep learning curve
Application. (client-server • Major vendors are
both in java) providing paid tooling
• No need to work around support
browser fallacies • AJAX apps development
• Free tooling support are tedious & errorprone
• Lots of ready baked • Building,Reusing,Maintaini
widgets ng large JavaScript apps
• API support for Maps & are fragile & painful
Visualization • Browser Quirks (& more...)
• Fastest AJAX (And More..)

5. GWT Visualization API
Graphs,Charts & Maps
Motion Chart Widgets - Run Re-Use any pre-built
with datastore/Spreadsheets visualization widget by
providing the datasource
connection.Pie Charts , Bar
Charts , Geo Maps on the
Cloud.
Create a highly responsive
AJAX application on the
cloud.
Annotated Timeline, Stock
Monitoring Charts & other
complex charts in a jiffy

6. Google Maps API for GWT - A Geocoding Tour
Deffault Cloudy Mashups
Create stunning 2D Maps with geographical Serve Images on Maps more efficiently with
data & Highly interactive markers! lower load time on Google Cloud.
No Flex , No Scripts, Java API Data
Know Java! You already know how to write
Maps Applications! Don't envy Flex apps!! Have Data will Map!! Bring any geocodable
Bring your years invested in Java to Maps! data representation JDO/JPA , JSON OR
XML.
It supports all ! Well , almost all ;)
