En 2020, améliorer l’efficacité des collaborateurs et la performance des entreprises se fait nécessairement à travers la transformation digitale des entreprises. En Europe, 65% des CEO déclarent être concernés par le sujet et attendre des résultats de leurs équipes. Avec l’Observatoire de l’Automatisation des Métiers, IDC fait un état des lieux de la progression du sujet au sein des DSI françaises: - Quelle est l’ampleur et l’avancée de la digitalisation des processus ? - Quel est l’impact opérationnel de cette digitalisation sur les organisations et sur leurs clients? - Quelles sont les stratégies développées et mises en oeuvre par les grands groupes? - Quelle collaboration pour les DSI avec les métiers ou la direction générale ? - BPM, RPA, ACM et IA: quel est l’outillage technologique déployé par les équipes IT? Mêlant automatisation, robotisation et optimisation tout en tirant parti des nouveaux paradigmes logiciels (API, connectivité et extensibilité des systèmes, cloud computing), IDC dresse à travers son analyse le portrait de l’Intelligent Process Automation video: https://youtu.be/Lka0T-zfvlc

Solicitar registro empresarial, licencia de conducción, una subvención, realizar un pago, entre otras actividades administrativas, se facilitan gracias a las plataformas digitales que otorgan autonomía al ciudadano para poder realizarlas en tan solo unos cuantos clics. En este webinar te presentaremos la PTEL, Plataforma de Tramitación En Línea, que ayuda a mejorar las actividades de las organizaciones públicas, desde la reducción de costes hasta el incremento del valor, gracias a la excelente experiencia de usuario que brinda a la comunidad electrónica. Esta plataforma, creada con Bonita, coordina la forma de trabajar (personas, procesos y tecnología) y mide su eficacia con el paso del tiempo. Combina la mejora de procesos con la automatización. Es un poderoso vehículo para la innovación social.

The penultimate chapter of our series on good practices focuses on these. You’ll see how to help your web development team be more efficient with Bonita, leveraging the low-code capabilities of the UI Designer with some tips on manipulating web elements. Then we’ll look at infrastructure configuration to prepare for production release.

When you’re building (micro)services, you have lots of framework options. Spring Boot is no doubt a popular choice. But there’s more! Take Quarkus, a framework that’s considered the rising star for Kubernetes-native Java. It always depends on what's best for your situation, but how to choose the best solution if you're comparing 2 frameworks? Both Spring Boot and Quarkus have their positives and negatives. Let us compare the two by live coding a couple of common use cases in Spring Boot and Quarkus. After this talk, you’ll be ready to get started with Quarkus yourself, and know when to select Quarkus or Spring Boot.

The microservices honeymoon is over. When starting a new project or revamping a legacy monolith, teams started looking for alternatives to microservices. The Modular Monolith, or 'Modulith', is an architecture that reaps the benefits of (vertical) functional decoupling without the high costs associated with separate deployments. This talk will delve into the advantages and challenges of this progressive architecture, beginning with exploring the concept of a 'module', its internal structure, public API, and inter-module communication patterns. Supported by spring-modulith, the talk provides practical guidance on addressing the main challenges of a Modultith Architecture: finding and guarding module boundaries, data decoupling, and integration module-testing. You should not miss this talk if you are a software architect or tech lead seeking practical, scalable solutions. About the author With two decades of experience, Victor is a Java Champion working as a trainer for top companies in Europe. Five thousands developers in 120 companies attended his workshops, so he gets to debate every week the challenges that various projects struggle with. In return, Victor summarizes key points from these workshops in conference talks and online meetups for the European Software Crafters, the world’s largest developer community around architecture, refactoring, and testing. Discover how Victor can help you on victorrentea.ro : company training catalog, consultancy and YouTube playlists.

Tracing the root cause of a performance issue requires a lot of patience, experience, and focus. It’s so hard that we sometimes attempt to guess by trying out tentative fixes, but that usually results in frustration, messy code, and a considerable waste of time and money. This talk explains how to correctly zoom in on a performance bottleneck using three levels of profiling: distributed tracing, metrics, and method profiling. After we learn to read the JVM profiler output as a flame graph, we explore a series of bottlenecks typical for backend systems, like connection/thread pool starvation, invisible aspects, blocking code, hot CPU methods, lock contention, and Virtual Thread pinning, and we learn to trace them even if they occur in library code you are not familiar with. Attend this talk and prepare for the performance issues that will eventually hit any successful system.
