Java Euro Tour

Bruno Souza, Edson Yanaga, and Otávio Santana are touring European JUGs talking about DevOps, big data, currency API, CDI 2 and cloud scalability. The team is also interviewing Java Champions, renowned Java speakers and community leaders in their homes and at work. Watch the replay of those interviews 

Some of the topics they present at JUGs: 
  • Containers and DevOps: full delivery cycle for Java applications  
  • Big Data and NoSQL with CDI and Cassandra 
  • First steps with the Money and Currency API, JSR 354 
  • Using CDI 2.0 in Java SE world - Contexts and Dependency Injection 2.0 (JSR-365) 
  • A Developer's Journey From Monoliths to Microservices 
  • Multi-cloud scalability: NoSQL with Cassandra, JavaEE, CDI and Containers. 
Java champions and community leaders interviewed include Andres Almiray, Ixchel Ruiz, Michael Hoffer, Wener Keil, Hendrik Ebbers, and Simon Ritter - to name a few. Watch the replay of all the interviews and follow the tour @brjavaman

Java Champion Jonas Bonér Explains the Akka Framework

In a new interview on otn/java, titled “Java Champion Jonas Bonér Explains the Akka Framework,” Jonas Bonér explores the intricacies of Akka, an open source platform for next-generation event-driven, scalable, fault-tolerant architectures on the JVM. He argues that the way concurrency is typically performed in Java with shared-state consistency is needlessly difficult, resulting in concurrent access to shared mutable state guarded by locks, which are notoriously hard to understand and get right. Locks, from Bonér’s perspective, do not compose, scale poorly, have complicated error recovery and are, generally, too low level.

From the article itself:

“Akka offers multiple solutions to the concurrency problem. It provides a toolkit for addressing concurrency, scalability, and high-availability concerns. It provides one thing to learn and one thing to use. Akka has multiple tools that will help you as a developer. Actors, futures, agents, and software transactional memory all raise the abstraction level and make it easer to write, understand, and maintain concurrent, scalable, fault-tolerant code. Instead of messing around with very low-level constructs, you think in terms of higher-level concepts such as message flows and transactions. What is usually solved by use of low-level plumbing in standard enterprise applications becomes workflow in Akka. So you start to think about how the data flows in the systems rather than how to get the concurrency and scalability exactly right.”
