Bebiendo del Stream: Como usar las plataformas de mensajería para escalamiento y rendimiento

Mark Heckler

Casi todos de los sistemas de misión crítica tienen elementos distribuidos o son totalmente distribuidos, resultando en numerosos retos: rendimiento, escalamiento, confiabilidad, elasticidad…​los ocho mitos del cómputo distribuido son vivos y bienes! Con frecuencia las plataformas de mensajería se usan para resolver estos problemas y aumentar las "+ilidades", pero no vienen sin complejidad por sí mismas. Ven a esta sesión para aprender cómo incorporar soluciones de código abierto como Spring Cloud Stream, RabbitMQ, y Apache Kafka para maximizar las capabilidades de tus sistemas distribuidos con complejidad mínima. Todos los ejemplos se escribirán en código en vivo y en tiempo real!

Diversión con Kubernetes y Payara Micro 5

Fabio Turizo

When developing a microservices architecture using containers, orchestration is key to provide an elastic scalable infrastructure. Kubernetes (w/ Docker) and Payara Micro 5 make this possible! This talk will showcase how to implement all of this for a real production scenario!

The Reactive Revolution

Josh Long

The reactive revolution continues. For as much as we've been talking about reactive programming in Spring for the last few years the journey has only just begun. Join me, Spring Developer Advocate Josh Long (@starbuxman), and we'll take our reactive applications further, looking at how to build microservices for cloud platforms like Pivotal Application Service (Cloud Foundry) and PKS (Kubernetes).

Quarkus: Fast, small, innovative, and native?!

Rafael Benevides

Java application booting and ready to serve requests in <10 milliseconds and occupying <40 MB on disk? With Hibernate ORM connected to PostgreSQL, Undertow web server, RESTEasy, CDI and Transaction Manager? Come and see how Quarkus makes all the above possible on top of Graal/SubstrateVM using new techniques such as Build Time Metadata Processing, Compile Time Boot; how runtime reflection can be eliminated at build time, etc. May sound geeky, but Quarkus still offers the first class developer experience: it shields you perfectly from the complexity of GraalVM, there is dev mode with instant reload, it is easy for the 80% most common use case and flexible for the remaining 20%. You do not need to learn a new technologies, because Quarkus supports existing best of breed libs and standards, such as Hibernate/JPA, JTA, CDI, JAX-RS, Eclipse MicroProfile and much more! A 5 ms demo will be included ;)

Modern Identity Management (en la Era de Serverless y Microservices)

Mercedes Wyss

Identity Management is an umbrella term for all of the core logic around identity. The main purpose of this talk is gain an in-depth knowledge of terms like manage provisioning, account management, identity governance, authentication, authorization, identity federation and how improve this with PaaS.

FullStack reactive with Spring and Angular

Loaine Groner

With RxJS and NgRx, Angular allows developers to fully use the power of reactivity in the front-end. But our back-end is still processing the good and old HTTP Ajax request. The newest version of Spring also introduced the reactive architecture, and along with Angular, we can leverage reactive architectures in the front-end and now also on the back-end with developer friendly code. In this session we overview these technologies and will dive into the code of real-world examples, using the most modern technologies we have available in the industry for enterprise applications.

Reactive for the Impatient

Mary Grygleski

One way to deal with the complexity of asynchronicity in programming is to introduce reactivity onto the coding level (reactive programming), and/or to handle it on the design and architecture level (reactive systems design).

Serverless Java Beyond Lambda: What every Developer Must Know

Frank Munz

In this presentation I will talk about what you must know beyond AWS Lambda to successfully implement serverless Java projects. I will cover new features of Lambda, cold start times, the role of Apache 2.0 Firecracker, serverless relational DB and on demand NoSQL DB for scaling and more.

Tags: Serverless, Java, Lambda, Firecracker, Open-source

Java & AWS: They are a beautiful couple

Julian Castellanos

Is not a secret for anyone the tremendous success that Java & AWS have had in their respective niches, but are we taking advantage of both of them running together? In this talk, I want to make an overview to the different possibilities we have of using these 2 platforms acting as a dream team.

Nowadays Architecture Trends, from Monolith to Microservices and Serverless

Alberto Salazar

Attendees will learn about a real-world evolution to a Distributed Architecture without being involved of a complete Microservices Madness; we will be covering tips and tricks of an experience of a evolution of a big EAR Core Banking Application and how we evolve to a modern distributed Architecture
