Chapter 1, What is Hazelcast?, helps us to get introduced with the technology, its place in an application's stack, and how it has evolved from traditional approaches to data.

Chapter 2, Getting Off the Ground, helps us start coding and get acquainted with the standard distributed data store collections on offer.

Chapter 3, Going Concurrent, helps us expand to look at more distributed and concurrent capabilities we can bring into our applications.

Chapter 4, Divide and Conquer, helps us look at how data is split up and split across many nodes to provide both performance and resilience.

Chapter 5, Listen Out, helps us discover that we can register to receive notifications from the cluster to enable our application to be aware of the goings on.

Chapter 6, Spreading the Load, helps us move beyond the data storage, and we investigate the distributed execution service and how Hazelcast is more than just a database.

Chapter 7, Typical Deployments, helps us explore the various ways we can use or install Hazelcast into our application or infrastructure, looking at the architectural decisions, reasons, and trade-offs behind each one.

Chapter 8, From the Outside Looking In, helps us look at popular alternative access we have to our data rather than using the provided drivers for integrating with a Hazelcast cluster.

Chapter 9, Going Global, helps us explode onto the world stage using the public cloud infrastructure and asynchronous remote replication to take our data all around the globe.

Chapter 10, Playing Well with Others, helps us bring the technology together with popular companion frameworks to see how we might start to bring the technology to work with legacy applications.

Appendix, Configuration Summary, helps us overview of the configurations we have used throughout the book.

Hazelcast is a Java-based technology so you will need a Java development environment (ideally Java 6 or newer) and use of a Java source code editor, preferably an IDE.

If you are software architect or Java developer looking to make your applications more scalable or looking to move into the cloud, Hazelcast is a technology you should strongly consider. This book seeks to provide an easy introduction to this innovative data centric framework and into its new way of thinking.

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text are shown as follows: "A GET method to retrieve an entry, returning a 200 OK response for keys that hold a value and 204 No Content for keys that do not."

A block of code is set as follows:

$ pyton memcache_example.py
{'country': 'GB', 'name': 'London', 'population': 8174100}

$ php -f memcache_example.php
array (
  'name' => 'London',
  'country' => 'GB',
  'population' => 8174100,
)

Any command-line input or output is written as follows:

$ curl -v -X POST -H "Content-Type: text/plain" -d "bar" \
http://127.0.0.1:5701/hazelcast/rest/maps/test/foo

< HTTP/1.1 204 No Content
< Content-Length: 0

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Now, just go the File menu and click on New".
