    Blockchain – the Myth and Realities
    In this talk I'll discuss some of the common myth and realities based on recent major industry and technology trends and scenarios in Blockchain. Examples of major industry trends - Decentralized digital identity technology and it's implementation in Health Pass, providing a solution for tracking Covid-19 vaccines and tests - Digital Tokens with privacy and how they are revolutionizing the banking industry with CBDC (Central Bank Digital Currency) - Advanced privacy preserving AI/analytics frameworks, based on zero knowledge proofs and multi party computation, applied to our leading solutions like BTS (Blockchain Transparent Supply) Some examples of technology trends - A new centralized blockchain model, based on database concepts enhanced with blockchain characteristics - Crypto Currency platform that allows us to connect the physical and digital world and provide the ultimate provenance in supply chain scenarios - Blockchain interoperability framework that allows to transfer Tokens, data and do atomic transacations across different DLT technologies such as HLF and Corda

    AR everywhere
    AR researchers and industry insiders have long envisioned that at some point in the future, a cloud AR platform that contains the Realtime 3D (or spatial) map of the world, will be the single most important software infrastructure in computing, far more valuable than Facebook’s Social graph or Google’s page rank index. Azure Spatial Anchor is a cloud AR platform that supports ARKit and ARCore . Azure mixed reality services offers SDKs and services that make it easier to build spatially aware, enterprise ready, cross-platform applications for AR across HoloLens, iOS and Android. In this session I will talk about the different verticals (Industry 4.0 , Retail ,IOT, Gaming, …) , the benefits of developing a cross-platform mobile AR application with Azure mixed reality services and how it changed Minecraft forever!

    Erik Ashepa (Fiverr)
    Fiverr Architecture V1-V5
    During the past 10 years, Fiverr migrated from a LAMP architecture all the way to 200~ Microservices with more than a dozen teams pushing a few hundred deploys a week. Working inside the monolith was simple, all data was available but the move to microservices presented challenges as data was exposed via REST API, which caused performance and reliability issues, dependencies between teams and much more... If you feel that your current architecture is brittle this talk is for you! I'll present our robust solution for sharing data across Microservices, utilizing Kafka as a data hub using techniques borrowed from CQRS and DDD to tie everything together and iterate much faster!

    DevOps and IaC - from zero to hero with KICS Open Source
    Over the last 6 months I've been involved with KICS Open Source project. Its goal is to help DevOps and DevSecOps secure their IaC. Mainly avoiding mis-configurations from escalating into production problems and security vulnerabilities. During this talk you'll learn what IaC is, understand some common problems, get tools to avoid having stories for the next FuckUp nights and integrate zero-to-hero tools in your CI/CD.

    Noa Berman Vyater (Next Insurance)
    From a Start-up Developer to a Scale-up Developer
    I started to work at Next-Insurance as the second BE developer, back then we were a small startup and we needed to move fast to succeed. 5 years later we are ±100 BE developers and more than 200 people in R&D. This tremendous growth required a huge change in my mindset as my team and I needed to adjust our code to an increasing number of products very quickly. For example, in our world-changing, a name for a customer means to change each insurance policy (AKA product) separately. Each one of these products may have different behavior but the general idea is pretty much the same. It took us more than a quarter to launch our second product from a post-purchase operation perspective but today it will take us less than 2 days to support all of the post-purchase operations. I would like to talk about a developer mindset - Working for a small startup mindset vs working for a big company mindset. - The development process is different - we need to understand that affecting a small number of customers and few developers is very different from affecting thousands of customers and hundreds of developers. - CI/CD from manual work to automatic process - Tests in a world without QA - Design code that will help you to scale - 1 product or N products thinking is very different and I would like to represent the thinking process. - Demonstration of writing scalable code + screenshots and specific examples.

    Ohad Israeli (Natural Intelligence)
    Neptune Graph Database from 0 to Production
    How would you combine NodeJS, Confluence Kafka and AWS Neptune to map relations between entities in real time? Over the session we will learn from the experience gathered at Natural Intelligence, starting from an idea of an entity mapping system toward the design and implementation of a real working production system. We will start with questions like what is a Graph database ? Why did we choose to use it and How do you query it specifically if you are using NodeJS. We will get into the architecture of the solution, how we used event sourcing and mapped our internal entities on top of a graph database. If you are thinking of adding a graph database to your solution or want to learn how to build a complete development lifecycle with Kafka and AWS Neptune this session is for you with lots of tips,recommendations and how-to guidance.

    Scaling databases: Do's and Don'ts we learned from analyzing 600,000 SQL queries
    Whether you're working with an ORM or writing native SQL, you've probably spent some time optimizing your database performance, instead of doing more of what you actually like to do. In this talk we'll discuss the top pitfalls we discovered after analyzing 600,000+ queries, written by thousands of startups and enterprise companies. We'll provide actionable tips you can implement first thing tomorrow morning.
