Testability is more important than ever. With short ship cycles and the desire for continuous delivery, it is critical to quickly know if a modification has destabilized your code base. This session will enable you to use a dependency injection container of your choice to create testable code. We will examine tightly coupled code and what problems it causes and how DI can be used to avoid these problems. The Unity DI container will be used as the medium to understand the concepts.
Analysts predict that there will be anywhere from 24 to 200 billion Internet connected devices by 2020. Imagine every device as an object that is capable of exchanging voluntary information about itself and its environment as well as executing commands via APIs to act on their environments. What's more, the analytical insights gleaned from this data will have the potential to transform existing business while creating new ones. The Internet of Things is here, and the heterogeneity of devices, messaging considerations, security constraints, volume of data and compute requirements are significant. In this talk, seven-time MVP and Microsoft Azure MVP Rick G. Garibay will provide a deep dive into the various ways in which devices can be connected today and how a service-assisted communication model is really key to tackling the myriad of constraints that exist today. We'll explore the strengths and weaknesses of various communication models and application protocols and how the Azure Reykjavik Device Gateway Accelerator addresses your needs today while providing the extensibility and scale to meet your needs as your IoT strategy grows. You'll learn how to get up and running on your Azure subscription with the Master and Partition roles, how to register a device and flow telemetry, inquires, commands and notifications through the Reykjavik fabric leveraging Azure Storage, HD Insight along with a look at how you can extend the fabric with custom protocol gateway and telemetry adapters.
В докладе будет рассмотрен вопрос асинхронного ввода-вывода, который является одним первоочередных для масштабируемости приложений. Кроме того, будет подробно разобраны виды асинхронности; отличие CPU-bound и I/O-bound задач; подробно разобран разбор механизма "I/O Thread" в .NET на платформе Windows, а также особенности ASP.NET и ASP.NET Web API.
