Devoxx Belgium 2018 - Let Pivotal and AxonIQ take you on a journey into Axon Trader. Axon Trader is a new open-source reference architecture that demonstrates how to use Spring, Axon and Pivotal Cloud Foundry to deliver evolutionary microservice applications to prod in minutes. The accompanying YouTube video can be found here: https://www.youtube.com/watch?v=15hzHUI4WNA

A Reference Architecture Open-source CQRS & Event Sourcing Spring Boot Axon Framework PCF (Pivotal Web Services) URL axontrader.cfapps.io Introducing Axon Trader
Spring Boot Javas most popular microservices framework Is there anyone who hasnt heard of SpringBoot? Fast, easy to build stand-alone Spring applications Opinionated starter dependencies that autoconfigure starter-web is great for RESTful microservices Embeds Tomcat, Jetty or Undertow Production-ready features (metrics, health, config) Easy to get started with guides & initializer https://spring.io/projects/spring-boot
Axon Solving non-functional app complexity in Message-Driven systems Open Source (Apache 2 License) Java framework First-class support for CQRS, DDD and EDA concepts Aggregates & Aggregate Roots Commands, Queries and Events Event Sourcing Sagas Helps focusing on the business functionality in your application https://axoniq.io/
PCF The premier platform for cloud-native development Focussed on developer productivity The fastest path to production Fully polyglot with support for Java, .Net, NodeJS, Python, etc. Marketplace services - DBs, MQs, APMs, etc. Highly automatable & CI / CD friendly Deploy code to production 000s of times a month! Available online via Pivotal Web Services (PWS) at run.pivotal.io

Wallet Id: 123 Owner: Steven Balance: 1000 Event Sourcing, what is it? C.R.U.D. Event Sourcing WalletCreatedEvent: Id: 123, Owner: Steven > Balance: 0 CashDepositedEvent: 1500 > Balance: 1500 CashWithdrawnEvent: 500 > Balance: 1000 CashWithdrawnEvent: 500 > Balance: 500 CashDepositedEvent: 500 > Balance: 1000Balance is persisted, but how we got here isnt clear. Great for projections and views, but somewhat lossy. Example: Virtual Wallet
"Event" and Message" are not the same thing! PublicAPI Message Driven APIs: what do they consist of? Commands Route to single handler Use consistent hashing Return a result Events Distribute to all event handlers Consumers express ordering reqs Return no result Can be persisted Can be a source of agg. state Can be used to build projections Queries Route with load balancing Sometimes scatter/gather Return a result
Virtual Wallet: lets code it!
Demo: Commissioning MySQL Database with PCF... No DBAs. No IT tickets. Just two simple commands: cf create-service Provisions a tablespace with inline with the selected plan Fully automated - no manual steps cf bind-service Creates a dedicated user for the application with credentials Adds the connection string and credentials into the applications environment variables (picked up automatically by SpringBoot)
No servers. No containers. No ssh. Just one simple command: cf push Uploads your code to Cloud Foundry Layers required runtimes (e.g. JVM) onto a hardened container Sets up a route (URL) for your app Creates a load balancing entry for each instance Sets up SSL termination and mTLS Creates health monitoring & logging subsystems Binds all required backing services (database, messaging etc.) Schedules your app container to start Starts your app with the desired number of instances (scale) Automatically restarts your app should it ever stop... Demo: Pushing code to production with PCF...
But how does this help us..?
