Topic: Java Backend & Microservices.

Conference Proposal:
Microprofile. A community proposal to the world of microservices.

The agility that the industry demands for the construction of web applications, together with the growth of the world of microservices, generated the emergence of this initiative.
Microprofile is the answer of several companies interested in the java language to give validity and inject dynamism to the enterprise part of this language.

Now, with the support of Oracle, microprofile presents itself as a much more robust option for the construction of microservices.

The objective of the talk is to know about this initiative, what is its objective and how to start using it in our next projects.

Developers are always focusing on writing software and getting it out there. But once that's done, it will need continuous maintenance, and it needs to be carefully planned, or it will inevitably suffer from bit rot, become outdated, and be really hard to modify when the need arises.

Description

In 2004 I wrote a transactional switch from scratch. Today it's still being used, in eight different deployments. And it's gone through several significant upgrades to keep it up to date, so that it doesn't become "legacy" software: framework updates, Java version updates, library updates, internal architecture updates, languages added (and removed), several optimizations... keeping a piece of software up to date is very hard work and needs careful planning.

Notes

These are the lessons I learned while maintaining a system I wrote more than a decade ago and which I have kept up to date throughout the years, improving it along the way. I think it's important to share this knowledge because people focus too much on writing stuff, deploying it, then forgetting about it. Maintainable software is something you have to design for.

Abstract

Reactive programming is a great tool for the skilled developer, enabling us to deliver more scalable, resilient, & responsive services…​but only if we leverage the reactive model throughout the entire stack! Failing to (re)design our systems to leverage fully reactive data storage & retrieval can both increase complexity and degrade performance.

Using Spring Data and your favorite NoSQL data store, you can exploit the full power of reactive systems, all the way to the metal. In this session, the presenter discusses & compares reactive support for MongoDB, Cassandra, Couchbase, & Redis, then demonstrates how to put each of them into production by live coding real-world examples. Come to this session to level up and block no more!

Description

This talk discusses how to build a highly scalable, mission-critical microservice infrastructure with Apache Kafka, its Streams API, and Apache Mesos.

Agenda

• Microservices with Kafka
• Kafka and Confluent Platform
• Mesos and DataCenter OS
• Running Kafka on DCOS
• Kafka Streams
• KSQL

The Java Persistence API (JPA) is the go to solution for writing the persistence layer in many enterprise and cloud enabled applications. There are many tricks that can be applied to make the application performant, one on particular is the configuration of the second level cache (L2C for short). This talk presents a real use case searching for the optimal configuration of different JPA and L2C combinations. A walkthrough of the approach followed will be shown, from naive measurements, firsts tests, to finally JMH benchmarks.

Title: Reactive Java EE - Let Me Count the Ways!

Abstract:
As our industry matures there is increased demand for high-throughput, low-latency systems heavily utilizing event-driven programming, non-blocking I/O and asynchronous processing. This trend is gradually converging on the somewhat well established but not well understood term "Reactive".

This session explores how vanilla Java SE and Java EE aligns with this movement via features and APIs like JMS, MDB, EJB @asynchronous, JAX-RS/Servlet/WebSocket async, CDI events, Java EE concurrency utilities and so on. We will also see how these robust facilities can be made digestible even in the most complex cases for mere mortal developers through Java SE 8 Lambdas and Completable Futures.

We know about the benefits of containers during development or deployment, for example containers help applications to be deployed easily and consistently, regardless of the target environment. They provide a clean separation of concerns, as developers focus on their application logic and dependencies. In this session we will show several examples of how easy is to use containers during integration tests. Best practices and open source libraries like testContainers will be explained and demoed. Note: This is a real-life project story! # #

We are living in a constantly changing world with increasing IT challenges both in size and complexity. Sorting out these challenges and turning them into opportunities requires a creative, adaptable, and effectively allocated team. Understanding underlying differences in diverse teams, such as differences in functional background, education, or personality, can facilitate creativity or group problem solving—but only when a group process is well defined. In this talk we will explore the idea of group process and diversity beyond race/ethnicity, gender, or age.

Title: Pragmatic Microservices with Java EE and Thorntail

Abstract:
Microservices are everywhere these days or at least the term is. Microservices have brought a fresh crop of frameworks to the Java EE ecosystem. In this session, we will explore this landscape using Thorntail (formerly WildFly Swarm) as an example. Thorntail supports development of Java EE microservices using standard APIs. We will discuss the currently available options, advantages, disadvantages and uses of these frameworks for Java EE developers – all using Thorntail based demos. We will also briefly discuss the road map of the open source Thorntail project and some of its cool features. Thorntail is one of the earliest and most mature Java EE based microservice frameworks. The project is part of the MicroProfile initiative.

Sumario

Programación reactiva ofrece desarrolladores de Java la habilidad de construir servicios elásticos, responsivos, y dirigidos por mensajes…​pero muchos desarrolladores de Java no saben donde empezar. La iniciativa "Reactive Streams" nos provee una base y el proyecto Reactor nos da una manera excelente para que nos hagamos inmediatamente productivos por aprovechar las capacidades reactivas de principio a fin. Si tiene experiencia con sistemas Spring MVC o sistemas "funcionales", Reactor le dará el poder para crear rápidamente y eficientemente aplicaciones reactivas de Spring Boot 2.

En esta sesión, el presentador explora el "web runtime" nuevo basado en Netty y demuestra como:

• integrar fácilmente con tecnologías existentes de Spring
• migrar con facilidad desde aplicaciones y sistemas que bloqueen
• definir su API en estilos imperativos y funcionales, cosechando todos los beneficios de ambos
• aprovechar nuevos mecanismos poderosos para probar sus aplicaciones y mejorar su código y su vida :)

El orador programará en vivo y en tiempo real todos los ejemplos. Esta no es una discusión abstracta, venga para ganar conocimientos prácticos!

Motivation
In this era of building systems based on microservices architecture, which tends to be more complex interacting among them and third party services, an eventual failure, response delay or systems that are not able to handle (lets say legacy systems) our current load are are most likely to happen.

Proposal
The intention of this talk is to show some of the actions to design microservices keeping in mind that will have failures. Some of these actions are:

• Circuit breaker
• Retries
• Rate limit
• Caching

Java 8 Concurrency API

Use of lambdas and functional programming style for developing concurrent applications using Java 8 Concurrency API

Kotlin is the hot new language for the JVM, and a shiny new toy for many developers. Come and learn what it has to offer, its benefits and advantages over Java, and how to avoid shooting yourself in the foot when you start using it.

Description

In May 2017, Google announced it would officially support Kotlin on the Android platform. This was the first name a lot of people heard about the language, and curiosity about it has increased enormously since then.

However, the language has been around for about 5 years. It has some neat features but as is usual with new toys, programmers tend to overuse them at first, which can cause unnecessary problems. In this talk I want to highlight some of the language's features which can be very useful by themselves but can become the cause of long "huh?" moments when combined.

The language features I cover in this talk are operator overloading, method extensions, destructuring, named invocations, defaulted parameters, data classes and a few others. I also talk about certain inconsistencies in the language syntax which can be a source of confusion for new adopters.

notes

Kotlin has been gaining popularity fast since it got Google's "blessing" when official support for Android was announced. Many Java and Android developers are adopting it to various degrees, and many programmers focus only on the new features, syntax, etc, without carefully reviewing the language design. It's important to think about how the features of a new language can be used to your advantage, so that they don't become a hindrance in the later stages of a project.

Title: Java EE 8 and the Open Future of Java EE - What You Need to Know!

Abstract:
Java EE 8 has been the most community opinion driven release in the history of the platform. Java EE 8 solidly enables HTTP/2, Server-Sent Events (SSE), JSON and aligning all parts of the platform with Java SE 8. It includes a much awaited security API overhaul as well as a slew of critical updates to APIs like JSF, JPA, JAX-RS and CDI.

While the road to Java EE 8 has not been smooth, the future of Java EE looks brighter than ever. Innovative efforts like MicroProfile aim to add features like dynamic configuration, health-checks, fat-jars, dynamic discovery and circuit breakers to Java EE. Most importantly Java EE is headed to a much more open future outside the walls of Oracle in the Eclipse Foundation.

This session will explain all of these promising developments including the details of what is in Java EE 8. We will also discuss the critical role Java EE and it's APIs play in maintaining the health of the entire Java ecosystem.

En los últimos años la Programación Reactiva ha surgido como una alternativa para diseñar aplicaciones y servicios que son capaces de reaccionar a cargas de trabajo en ritmo constante y/o que aparecen de manera imprevista. Esta capacidad permite a las aplicaciones escalar de manera natural en ambas direcciones, algo que no es fácilmente posible con otras técnicas. En esta plática veremos como empezar con este tema haciendo uso de tecnologías Java, haciendo uso de una demostración práctica.

Title: Taking Java EE to the Clouds

Abstract:

Title: What is CQRS+Event Sourcing and Why Should Java Developers Care?

Abstract:
CQRS (Command Query Responsibility Segregation) is a design pattern that originates in DDD (Domain-Driven Design) and emphasizes strictly separating reads from updates in the application model. Event Sourcing is a closely related technique that stores state as a series of events as opposed to only keeping track of the latest data. While these concepts are important on their own right, they are especially important for microservices development. In this heavily demo driven session we explore CQRS and Event Sourcing in detail using the Axon Java framework and Dockerized Spring Boot microservices running on AWS. At the end of the session you should have a good idea if CQRS and Event Sourcing are for you and why Axon helps in implementing these concepts.

Security is a major issue on current software ecosystem. Java is not the exception with major vulnerabilities impacting many Java libraries that Java Developer don't even know that are there.
Also, many security problems come from design and incorrect use of existing libraries/frameworks.
This workshop aim to give hints on how to test your web applications and REST API's to improve the security of your code.

A lo largo de los últimos meses hemos estado hablando de los grandes cambios en el ecosistema de Java, sobre todo en el ámbito de Enterprise Edición. Durante la charla hablaremos de servicios y su implementación a través de AppServer basados en Microprofile. Los usos son múltiples pero sobre todo de un ámbito de desarrollo horizontal en cualquier organización. Para los curiosos del "ultimo grito de la moda" tocaremos brevemente las arquitecturas distintivas de microservicios y servicios.

Al final podemos ver que nada está dividido ni tampoco super integrado requiere de trabajos de conceptualización, pruebas de concepto y pruebas de arquitectura.

Entonces la invitación es a viajar por el camino de JakartaEE hacia back-ends realmente robustos.

Title: Applied Domain-Driven Design Blueprints for Java EE

Abstract:
Domain-Driven Design (DDD) is an architectural approach that strongly focuses on materializing the business domain in enterprise software through disciplined object-oriented analysis. This session demonstrates first-hand how DDD can be elegantly implemented using Java EE via an open source project named Cargo Tracker.

Cargo Tracker maps DDD concepts like entities, value objects, aggregates and repositories to Java EE code examples in a realistic application. We will also see how DDD concepts like the bounded context are invaluable to designing pragmatic microservices.
