Tweaking performance on high-load projects

Dmitriy Dumanskiy

Big commercial websites breathe data: they create a lot of it very fast, but also need the feedback based on the very same data to become better and better. In this talk we're showing our ideas, the drawbacks and the solutions, for building your own big data infrastructure. We further explore the possibilities to access and harness the data using map/reduce and near real-time approaches in order to prepare you for the most challenging part of it all: gaining relevant knowledge you did not had before. This talk was held at the Developer Conference 2013 (http://www.developer-conference.eu/session_post/log-everything/)

Internet of Things è uno degli scenari di mercato più importanti su cui investire entro il 2020. L'Internet of Things permette di trasferire sul Web la vita reale delle persone grazie all'interazione con oggetti e spazi fisici scambiando un grande volume di dati. Durante il Lab è stata fornita una descrizione di architettura necessaria a supportare progetti di Internet of Things con un focus sull'organizzazione dei dati all'interno di MongoDB, database NoSQL Leader di mercato, per raccogliere ed analizzare grandi volumi di dati in tempo reale ed in modo efficiente.

MongoDB Solution for Internet of Things and Big Data

Stefano Dindo

Le aziende sono chiamate a rispondere velocemente ai cambiamenti di mercato a seguito dell’affermarsi di nuovi scenari (Internet of Things, Social Analysis, manifattura 4.0 ecc.) che richiedono sempre di più l’integrazione con nuove tecnologie. Trattandosi di progetti innovativi, che impattano su processi e contesti aziendali, è fondamentale disporre di soluzioni flessibili per la raccolta e l’analisi dei dati. MongoDB è un database NoSQL in grado di offrire flessibilità, scalabilità e semplificazione delle attività di sviluppo. Il lab avrà lo scopo di illustrare come creare architetture MongoDB e svolgere attività di Schema Design per la gestione dei dati in ambito IoT e Big Data facendo inoltre riferimento a casi pratici reali che si basano su tecnologie Cloud, necessarie a far fronte ad un mercato sempre più globale.

Data analysts, data engineers, and application developers are supporting unprecedented rates of change, whether talking about latency requirements to the expanding arena of data usage scenarios. While the technology functionality must rapidly evolve to meet customer needs and respond to competitive pressures, how can we enhance the data platform to help manage this unpredictability? To help address these realities, data practitioners from a diverse set of backgrounds are increasingly relying on schema-free, distributed, scalable, and high-performance data storage (also known as NoSQL databases). In this session, we will showcase a wide variety of customer scenarios, business goals, and technical challenges faced by real-world customers. More importantly, how adding Azure DocumentDB into a data practitioner's arsenal within the Microsoft/Azure data ecosystem will allow you to easily solve these complex design patterns at massive scale.

Users increasingly demand a far richer experience from web applications – expecting the same level of performance and interactivity they get with native desktop and mobile apps. At the same time, there's pressure on developers to deliver new applications faster and continually roll-out enhancements, while ensuring that the application is highly available and can be scaled appropriately when needed. Fortunately, there’s a set of open source technologies using JavaScript that make all of this possible. Watch this presentation to learn about the two dominant JavaScript web app stacks – MEAN (MongoDB, Express, Angular, Node.js) and MERN (MongoDB, Express, React, Node.js). These technologies are also used outside of the browser – delivering the best user experience, regardless of whether accessing your application from the desktop, from a mobile app, or even using your voice. By watching this presentation you will learn: What these technologies and how they’re used in combination: NodeJS MongoDB Express Angular2 ReactJS How to get started building your own apps using these stacks Some of the decisions to take: Angular vs Angular2 vs ReactJS Javascript vs ES6 vs Typescript What should be implemented in the front-end vs the back-end

In the thrilling conclusion to 2023, ransomware groups had a banner year, really outdoing themselves in the "make everyone's life miserable" department. LockBit 3.0 took gold in the hacking olympics, followed by the plucky upstarts Clop and ALPHV/BlackCat. Apparently, 48% of organizations were feeling left out and decided to get in on the cyber attack action. Business services won the "most likely to get digitally mugged" award, with education and retail nipping at their heels. Hackers expanded their repertoire beyond boring old encryption to the much more exciting world of extortion. The US, UK and Canada took top honors in the "countries most likely to pay up" category. Bitcoins were the currency of choice for discerning hackers, because who doesn't love untraceable money?

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.
