Cloud Computing Solutions with
Amazon SimpleDB
A Developer s Guide to Amazon SimpleDB
Using SimpleDB, any organization can leverage Amazon Web Services (AWS), Amazon s powerful cloud-based
computing platform
—
and dramatically reduce the cost and resources associated with application infrastruc¬
ture. Now, for the first time, there s a complete developer s guide to building production solutions with
Amazon SimpleDB.
Pioneering SimpleDB developer Mocky Habeeb brings together all the hard-to-find information you need to
succeed. Mocky tours the SimpleDB platform and APIs, explains their essential characteristics and tradeoffs,
and helps you determine whether your applications are appropriate for SimpleDB. Next, he walks you through
all aspects of writing, deploying, querying, optimizing, and securing Amazon SimpleDB applications
—
from the
basics through advanced techniques.
Throughout, Mocky draws on his unsurpassed experience supporting developers on SimpleDB s official Web
forums. He offers practical tips and answers that can t be found anywhere else, and presents extensive
working sample code
—
from snippets to complete applications.
With A Developer s Guide to Amazon SimpleDB you will be able to
Evaluate whether a project is suited for Amazon
SimpleDB
Write SimpleDB applications that take full
advantage of SimpleDB s availability, scalability,
and flexibility
Effectively manage the entire SimpleDB
application lifecycle
Deploy cloud computing applications faster
and more easily
Work with SELECT and bulk data operations
Fine tune queries to optimize performance
Integrate SimpleDB security into existing
organizational security plans
Write and enhance runtime SimpleDB clients
Build complete applications using
AJAX
and
SimpleDB
Understand low-level issues involved in writing
clients and frameworks
Solve common SimpleDB usage problems and
avoid hidden pitfalls
This book will be an indispensable resource for every IT professional evaluating or using SimpleDB to build
cloud-computing applications, clients, or frameworks.
Mocky Habeeb is the most active, highest-rated user on the official SimpleDB Web forums, providing
answers and guidance to developers seeking authoritative answers. Currently Head of Web Architecture
and Development for Infrawise, Inc., he has been designing Web frameworks for over a decade and has
