GraalVM and MicroProfile - A Polyglot Microservices Solution

Roberto Cortez

Microservices need to support many programming languages, requiring both a language-agnostic network protocol and a polyglot runtime environment. In addition, microservices written in one language may need to use APIs written in some other language. Using a traditional CRUD application implemented as a polyglot solution (Java, JavaScript, Python and Ruby) on GraalVM, this presentation demonstrates how MicroProfile JWT, MicroProfile Metrics, MicroProfile Rest Client, MicroProfile Health Check, and more can provide architecture-level interoperability across concerns.

Le temps est révolu où Java EE ne serait qu’à développer des applications de mise à jour de données, avec JSF / EJB / JPA. Aujourd’hui Java EE s’est assoupli et s’est ouvert sur le monde, avec CDI comme clé de voûte et a repoussé nos limites grâce à des capacités d’extension puissantes et faciles d’utilisation comme JCA. Dans un premier temps, nous reviendrons rapidement sur la place de CDI dans JavaEE 7 et sur ses mécanismes d’extension. Dans un deuxième temps, nous verrons les techniques de connecteurs JCA et comment ils peuvent aussi constituer une possibilité d’ouverture simple à mettre en œuvre. JCA fournit des techniques pour gérer des connexions sortantes ou entrantes, sur des formats ou protocoles variés.

César Hernández

Microservices need to support many programming languages, requiring both a language-agnostic network protocol and a polyglot runtime environment. In addition, microservices written in one language may need to use APIs written in some other language. Using the MicroProfile conference sample architecture implemented as a polyglot solution (Java, JavaScript, Python) on GraalVM, this presentation demonstrates how MicroProfile JWT, MicroProfile Metrics, MicroProfile Rest Client, MicroProfile Health Check, and more can provide architecture-level interoperability across concerns. Attendees interested in creating a polyglot solution on GraalVM compatible with MicroProfile will get a demo-heavy introduction with occasional dives into code and leave with read-to-run samples in GitHub.

Get Hip with JHipster - GIDS 2019

Matt Raible

JHipster is one of those open-source projects you stumble upon and immediately think, "Of course!" It combines three very successful frameworks in web development: Bootstrap, Angular, and Spring Boot. Bootstrap was one of the first dominant web-component frameworks. Its largest appeal was that it only required a bit of HTML and it worked! All the efforts we made in the Java community to develop web components were shown a better path by Bootstrap. It leveled the playing field in HTML/CSS development, much like Apple's Human Interface Guidelines did for iOS apps. This talk shows you how to use JHipster to build a Spring Boot API, an Angular UI, and make it all look good with Bootstrap. You'll learn how to deploy the generated project to Heroku too!

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management. The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM). Speakers: Bob Boule Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle. Gopinath Rebala Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf

Paige Cruz

Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack. While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack. I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
