Conference Milan 2023 | Software Architecture

Description:
If your company is dealing with a successful software that is becoming difficult to evolve, needing to be somehow refactored or migrated, preserving all the knowledge, this is your talk. Instead of rewriting, converting or using other common modernization approaches, we’ll look at a new paradigm, a new architectural style called “micro-executor”, transforming your legacy software into a serverless engineering platform . We’ll talk about interpreters, transpilers, domains specific languages, polyglottism. It will last for the next generations of technologies, using future-native principles.

Description:
Nel 2018, Intesa Sanpaolo ha deciso di adottare tecnologie open source (es. Kubernetes, Springboot, Angular, Kafka) e una paradigma a micro-servizi come standard per le proprie applicazioni full-stack e cloud-native. Condivideremo l'entusiasmante percorso attraverso cui abbiamo integrato le tecnologie, dando vita al nostro framework Darwin. Approfondiremo come Darwin è evoluto nel tempo in un prodotto industriale con un vasto ecosistema tecnologico. Questo ecosistema ha sostenuto in modo determinante progetti di rilievo, tra cui spicca la realizzazione della nuova banca digitale IsyBank.

Description:
L’Italia sta rivoluzionando le identità digitali. SPID e CieID (basato sulla Carta di Identità Elettronica) passano dal protocollo SAML2, al più moderno protocollo OpenID Connect (OIDC) che fornisce maggiore flessibilità, facilità di implementazione e ampia adozione. Il profilo OIDC italiano è basato su OpenID iGov e Federation. Quest'ultimo, recentissimo, definisce un modello di federazione gerarchica, sicura e scalabile di cui l'Italia è un entusiasta early adopter. Su OAuth/OpenID e sul paradigma Self Sovereign Identity viene definito il Wallet Europeo di Identità Digitale (EUDI Wallet).

Description:
In this talk we'll go through the microservices pattern that would help us create a robust integration architecture based on microservices. During the talk we're going to investigate some of the most applied design patterns with a focus on integration context such as Messaging pattern, Circuit breaker or Discovery. Check here the speaker's material.

Description:
I will introduce an implementation of rollback netcode (aka replay consistency or server reconciliation) in JavaScript. We'll look at the relevant bits of WebRTC Data Channels (a UDP-based bidirectional transport available in all modern browsers) for messaging, do a quick ELI5 of The Redux Pattern™ for deterministic state, and bring it together into an approach that is performant, easy-ish to reason about, server authoritative, optimistic, and convergent. Applicable to web games, XR experiences, collaborative drawing and document editing, and more! There will be demos (plural) and source code!

Description:
Distributed & concurrent systems have grown exponentially in popularity in recent years. However the vast majority of these systems are designed as untestable whiteboard drawings. This leads to fundamental design flows that go unnoticed in the design phase leading to hard to find bugs that are expensive to correct. This talk is about using formal methods modeling systems which are exhaustively-testable. The objective of the talk is to demonstrate how formal methods can be used to eliminate design flaws before system implementation is underway. Check here the speaker's material.

Description:
We will examine the technical decisions made during the scaling process from zero to 100,000 users, highlighting the transition from an external video platform to a fully integrated and optimized AWS-based encoding and content delivery architecture. This process involved overcoming several challenges, including the optimization of streaming performance and the management of associated costs. Our discussion will offer a comprehensive understanding of the technical requirements and considerations for building a successful video on-demand streaming service.

Description:
No one likes when there's a lot of tech debt, right? But how do we understand how much exactly we have of it? Where exactly does it sit? Which part of it is actually the most annoying? What would be the benefit of spending time tackling it? When you plan tackling your tech debt, all these questions deserve answers. Especially when we're asked about the ROI on our efforts. Also, we want to prioritise tech debt items well to spend effort wisely. This talk is about that: how we measure our tech debt, interpret the numbers to get the above questions answered, and take the right decisions after. Check out the speaker's slides.

Description:
Le moderne esigenze dei clienti mettono alla prova gli sviluppatori: elaborazione rapida dei dati, scalabilità illimitata e integrazione flessibile. I software “obsoleti” richiedono strategie adattabili e un approccio lungimirante. La nuova tecnologia favorisce l’innovazione! I vantaggi dei microservizi, Kubernetes per la scalabilità, l’analisi con Apache Spark ed il miglioramento del software tramite CI/CD. Esamineremo un caso di successo, illustreremo come le nuove tecnologie abbiano reso possibile vincere le richieste del mercato e garantire esperienze eccezionali per i nostri clienti.

Description:
The web is not just entertainment, information or compulsive commerce. The web is a tool capable of simplifying and digitizing processes that we never thought we could see on a browser. The speed with which technology is evolving allows us to simplify the healthcare experience from both the doctor's and patient's point of view. Let's see together which opportunities we create in recent years in the field of telemedicine and how we worked to realize them.
