Code Rally in a Nutshell
• Code Rally is an IDE and server, that allows the user to write AIs written
in Java (on WebSphere) or JavaScript (on Node.js), and then used in a
variety of interesting ways
• A user-friendly development environment that allows the writing of
simple AI code, which then becomes:
• Multi-player (race with other AIs simultaneously)
• Competitive (race replays, streaming, and leaderboard)
• Graphical (see races streamed in real-time)

Code Rally Tech and Architecture
• Everything we are showing is freely available right now
• Bluemix – the cloud technology behind Code Rally
• WASdev – home of WebSphere Liberty, which Code Rally is based
• Code Rally on developerWorks
• Open By Design
• Sneak a peak to see how it is implemented
• All the Code Rally code is open source in IBM DevOps Services (IDS)

WebSphere Liberty: Bluemix Cloud and Local
• The dynamic Java EE 7 platform that enables your applications and
drives developer productivity and rock-solid production support
• Fast startup, low memory footprint, easy to configure, includes all the
latest Java 8 and Java EE 7 tech, plus fully supported by IBM with
many additional tools/resources/samples/docs/support
• Write once, deploy everywhere: Docker (local/private/Bluemix),
Cloud Foundry Bluemix (Public/Local/Hybrid), Cluster, etc.

Web Technologies like Restful Web Services
and WebSockets Enables Polyglot Programming
• Communication with the Code Rally Server through standard Web
APIs, using HTTP requests, WebSockets and JSON.
• This central API is exposed and implemented by the WebSphere
Application Server application, with racers connecting through this
API to enter and compete in a race

13. #HybridCloudTour
Cloud Foundry and Docker on Bluemix
• Cloud Foundry is an Open Source PaaS offering, which underlies
IBM Bluemix's Cloud Foundry platform
• Rather than configuring and deploying a machine (IaaS), developers
target a runtime (WebSphere Liberty/Node.js/Asp.net/etc.), which
abstracts out the application infrastructure
• This lets developers focus on code
• Docker Containers allows the developer to package and deploy an
application and its dependencies across heterogeneous environments
• This allows developers greater control over the environment, and
is the basis for IBM Bluemix Containers

IBM DevOps Services — Delivery Pipeline
• The DevOps “glue” that ties together the Code Rally build, deployment,
and testing processes
• Automatically begins application deployment when a developer
commits a change set to Git
• Deploys builds to IBM Bluemix (both Cloud Foundry and Docker)
• But only if the automated test succeeds : )

15. #HybridCloudTour
Backend: Cloudant and DashDB
• Code Rally supports both local and cloud-based backend databases
• Cloudant is a NoSQL cloud database based on the open source
CouchDB, and DashDB is an analytics focused cloud database,
based on IBM DB2
• Provision a new 20GB cloud database with only a single command:
• CLI: cf create-service cloudantNoSQLDB Shared my_db
