Although you may not have heard of JavaScript Object Notation Linked Data (JSON-LD), it is already impacting your business. Search engine giants such as Google have mandated JSON-LD as a preferred means of adding structured data to web pages to make them considerably easier to parse for more accurate search engine results. The Google use case is indicative of the larger capacity for JSON-LD to increase web traffic for sites and better guide users to the results they want. Expectations are high for (JSON-LD), and with good reason. JSON-LD effectively delivers the many benefits of JSON, a lightweight data interchange format, into the linked data world. Linked data is the technological approach supporting the World Wide Web and one of the most effective means of sharing data ever devised. In addition, the growing number of enterprise knowledge graphs fully exploit the potential of JSON-LD as it enables organizations to readily access data stored in document formats and a variety of semi-structured and unstructured data as well. By using this technology to link internal and external data, knowledge graphs exemplify the linked data approach underpinning the growing adoption of JSON-LD—and the demonstrable, recurring business value that linked data consistently provides. Join us learn more about optimizing the unique Document and Graph Database capabilities provided by AllegroGraph to develop or enhance your Enterprise Knowledge Graph using JSON-LD.

MongoDB Atlas Data Lake is a new service offered by MongoDB Atlas. Many organizations store long term, archival data in cost-effective storage like S3, GCP, and Azure Blobs. However, many of them do not have robust systems or tools to effectively utilize large amounts of data to inform decision making. MongoDB Atlas Data Lake is a service allowing organizations to analyze their long-term data to discover a wealth of information about their business. This session will take a deep dive into the features that are currently available in MongoDB Atlas Data Lake and how they are implemented. In addition, we'll discuss future plans and opportunities and offer ample Q&A time with the engineers on the project.

MongoDB 3.2 introduces a new way for familiar Business Intelligence (BI) tools to access your real-time operational data – opening it up to data analysts and data scientist, enabling new insights to be discovered faster than ever before. Tableau accesses the JSON document data stored in MongoDB via this new BI connector. We will cover how the BI connector works by creating a relational view definition of a JSON data set that is then used to present a tabular SQL/ODBC interface to Tableau. Then we will set-up a live connection from Tableau Desktop to the MongoDB Connector for BI. Once we have Tableau Desktop and MongoDB connected, we will demonstrate the visual power of Tableau to explore the agile data storage of MongoDB. This webinar will cover: What is the MongoDB BI Connector? Setting up a connection from Tableau to the MongoDB BI Connector. How to perform data discovery Tableau connected to MongoDB live data. Publishing a Tableau Dashboard for sharing insights.

In this workshop we will set up a streaming framework which will process realtime data of traffic sensors installed within the Belgian road system. Starting with the intake of the data, you will learn best practices and the recommended approach to split the information into events in a way that won't come back to haunt you. With some basic stream operations (count, filter, ... ) you will get to know the data and experience how easy it is to get things done with Spring Boot & Spring Cloud Stream. But since simple data processing is not enough to fulfill all your streaming needs, we will also let you experience the power of windows. After this workshop, tumbling, sliding and session windows hold no more mysteries and you will be a true streaming wizard.

PostgreSQL is an object-relational database system. NoSQL on the other hand is a non-relational database and is document-oriented. Learn how the PostgreSQL database gives one the flexible options to combine NoSQL workloads with the relational query power by offering JSON data types. With PostgreSQL, new capabilities can be developed and plugged into the database as required. Attend this webinar to learn: - The new features and capabilities in PostgreSQL for new workloads, requiring greater flexibility in the data model - NoSQL with JSON, Hstore and its performance and features for enterprises - Spatial SQL - advanced features in PostGIS application with PostGIS extension

MongoDB – from "humongous" – is an open source, non-relational, document-oriented database. Trading off a few traditional features of databases (notably joins and transactions) in order to achieve much better performance, MongoDB is fast, scalable, and designed for web development. The goal of the MongoDB project is to bridge the gap between key-value stores (which are fast and highly scalable) and traditional RDBMS systems (which provide rich queries and deep functionality). This talk will introduce the features of MongoDB by walking through how one can building a simple location-based application using MongoDB. The talk will cover the basics of MongoDB's document model, query language, map-reduce framework and deployment architecture.

The proliferation of data from new data sources has generated greater demand for technologies that can handle and harvest value from unstructured data. Postgres is leading the movement of integrating unstructured data with the relational environment. Postgres first added JSON and then enhanced it with new data types, functions and operators in recent releases. Now in beta is the JSONB “binary JSON” type. These advances follow the longstanding HStore data type added in 2006 to support key/value stores in Postgres. Now Postgres users can learn how to harness these capabilities to master unstructured data challenges with Postgres. The presentation also covers: * An overview of JSON data types and operators * Examples of SELECT, UPDATE, etc * An examination of performance considerations For more information, please email sales@enterprisedb.com

The move to microservice infrastructure exposes new challenges, that are not typical for classic monolithic applications. Deployment, security, monitoring -- this list is far from complete. In this talk Serhiy will speak about how to establish a fast and reliable communication channels between microservices. What patterns, protocols and data formats are available. How to enforce a backwards compatibility and strict contract between services and their clients. When we should use sync or async communication style, and so on. Come to this session and hopefully you will come out with new ideas of how to build your stuff even better.

In these days, automation is the key to reduce the effort in governing complex system. Also, it reduces mistakes of manual, repetetive, operations. Despite the standardization of common approaches using text-based Infrastructure-as-code definitions, as YAML or JSON, I will suggest to write your provisioning templates using C# and .NET, against Microsoft Azure. In this demo-only session, we'll see the Azure Fluent Management Libraries in action to create a multi-tenant environment with strong-typed objects and compile-type-safe provisioning code.

“Domain Driven Design is an approach to software development for complex needs by connecting the implementation to an evolving model.” While there are many resources on the web about the DDD, they are generally theoretical rather than useful practical guides. One reason is that a DDD implementation quite varies depending on your domain and culture. However, it is still possible to provide some explicit rules those can help you while designing your code base. This talk starts by introducing the DDD and providing a layering model based on the DDD and the Clean Architecture. It then introduces the core building of an application built on the DDD principles. In the second part of the talk, it shows some strict coding rules for the core building blocks with real code examples and suggestions. These rules are essential to build a large scale application implements DDD patterns & practices. While the solution structure and code samples are based on .NET and C#, the talk is useful for developers and architects working with any server side technology.

GraphQL is a great way to expose your APIs and it has changed the way we think about consuming data over HTTP. With GraphQL we want to have one schema that provides all the data to us in a consistent way, enabling us to drill into the graph and fetch with one request what we actually want instead of having to issue multiple requests. In the real world, however, we more often build small services that serve certain use cases. Simpler services are easier to maintain and can be deployed more rapidly. Moreover, we often also want to use external services that are not built by us. Ultimately, we will end up with multiple APIs again. The solution for this dilemma is schema stitching. This talk will explore the schema stitching capabilities on ASP.Net Core with Hot Chocolate. We will show how you can set up a Hot Chocolate GraphQL gateway in under 5 minutes and move on to the various stitching scenarios. This talk introduces simple auto-stitching scenarios and goes on to demonstrate how you can rewrite your GraphQL APIs into something truly new.

В этом выступлении Андрей расскажет о внутренностях базового сервиса, написанного с использованием паттерна CQS, который обрабатывает входящие запросы команд и публикует события, описывающие переходы состояния системы. После этого он опишет общие способы тестирования такого сервиса и объяснит плюсы и минусы существующих подходов. Затем он расскажет про AutoFixture и покажет, как она может сделать тесты намного чище, а конфигурацию - более удобной, путем инъекции параметров в метод теста, объяснит существующие проблемы с инициализацией и очистке данных в асинхронных тестах и покажет, как с этим справляться с помощью некоторой легковесной интеграции между xUnit и AutoFixture.

Но это оказалось не так и сложно. В моем докладе я хочу вам рассказать о том что такое парсеры в целом, зачем они нужны и какие они бывают, а самое главное -- покажу как перейти от традиционных методик их написания к более удобному и понятному функциональному способу.

The majority of companies are struggling with an issue of growth where they started from handful group of people and reached 1000+ employees. In case of small groups the relationships remind family’s connections so everyone knows each other personally and the atmosphere is warm and charm whereas starting from 500+ to 1k keep it as family is tough and most of the companies come up with processes on one hand and culture on other. There ain’t no silver bullet how to manage it and in the end of the day they are balancing working a lot about good atmosphere in company and setting up relationships between teams. The issue isn’t new however tools and approaches evolved a lot this is where .NET Core and ML.Net comes in handy. These days AI/ML take over the world and bots as one of implementations are already a part of our life therefore our entuthiastic team created a bot using latest .NET Bot Framework v4 who helps managers to “measure” atmosphere in teams and crucial to socialize teams leveraging the power of ML.NET.

You must have noticed how Docker and containers is playing a more and more important part in .NET development. Docker support is everywhere, so it should be easy to build solutions based on container technology, right? But, it takes a bit more to architect and create a .NET solution that use Docker at its core. Many questions arise: How do you design a solution architecture that fits well with containers? Would I use .NET or .NET Core? What is a proper way to migrate to such an architecture? What changes in the .NET implementation from pre-Docker solutions with micro-services? Where do container orchestrators fit in and how do I build and deploy my solutions on a Docker container cluster, such as Azure Kubernetes Service? These and many other questions will be answered in this session. You will learn how to design and architect your .NET solutions and get a flying start to create, build and run Docker-based containerized applications.

Serverless technology is trending, but in-depth details are missing. How does it fit with non-serverless components? What are the practical use cases? Should you fight vendor lock-in? And what about limits and pitfalls with Azure? I will answer those questions, share a few tricks and short demo. I'll cover serverless usage scenarios with Azure, what problems can be solved, and what is a viable adoption strategy. Then I'm going to talk about technology shortcomings, when to omit it and how to rip all benefits. There are circumstances when a cloud-agnostic approach is beneficial, so I discuss serverless frameworks too and why vendor lock is not that bad. Finally, we'll look at a short demo that illustrates why you have to use specific serverless patterns.

Do you recall those buzz words like TDD, BDD? Yep, but we know their problems as well! TDD is too granular. BDD is too coarse-grained. Unit tests are too chatty. BDD is too abstract. TDD requires knowledge of implementation details. BDD does not care about implementation at all. What is in the middle? Integration tests. Let's be Integration driven then! OK, then how to build infrastructure to run Integration tests? Should we start with IaaS first? How to speed up the development and take into account non-foundational requirements like scaling, security borders, isolation, etc. from the very beginning? To answer the questions, we would combine Integration test-based development with serverless (AWS) to solve a typical business task. Based on the example, we would show how to create a solid foundation for further refactoring/refining of the overall solution and concreting it with Unit tests. Acceptance tests would be left for home exercise ;)

A Public Key Infrastructure (PKI) is the basis of modern system authentication; X.509 certificates are at the core of modern cryptography. Building your own PKI is not for the faint of heart, so we usually buy our certificates from an external Certificate Authority or operate a 3rd-party off-the-shelf PKI. But what can you do if you need to issue your own certificates while keeping your costs low? What if, for example, you're in the business of manufacturing millions of IoT devices and you need to issue a certificate to each and every one of them? And to top it off - you want to do it in a Serverless manner? Join me in this session, as we build a Serverless PKI system with Azure Functions & Key-Vault and learn all about Key-Vault's capabilities in regards to X.509 certificates along the way.
