How do you build an application
that uses Apache Geode?

How do you configure and bootstrap
Apache Geode for your application to use?

1. Install Apache Geode
2. Use Gfsh to start a Locator
3. Start Pulse
4. Start a Server
5. Create a replicated, persistent Region
6. Manipulate data in a Region and
demonstrate persistence.
7. Examine the effects of replication.
8. Restart the cache servers in parallel.
9. Shutdown the system including your
Locators.

Spring Data GemFire / Geode
1
Apply the Spring Framework’s powerful, non-invasive programming model &
concepts to simplify the configuration and development of highly-scalable,
distributed Spring applications based on Pivotal GemFire or Apache Geode.
Promise

1
Simplify the OOTB, getting started experience by reducing the friction to get up
& running as quickly and easily as possible.
Promise of 2016…

Apps are the currency…
