Serverless Architectures with Azure
Published by Packt Publishing
Implementing and deploying Azure functions at scale
Serverless is a relatively new concept and is already making huge waves across developers, architects, and organizations. The combination of serverless and cloud not only allows you to concentrate with the business problem in hand, it makes solutions faster, better and cheaper. It also helps you scale-up your solution, automate tasks, provide unlimited availability, and speed-up application performance, with the benefits of microservices. Microservices are also a relatively new paradigm that are changing the way organizations look at developing and deploying solutions in a completely different way.
The goal of this course is to architect, design, build, and deploy a fully automated serverless application on Azure. We’ll see how microservices fit into serverless and cloud concepts, and why the best results are obtained when these three paradigms are combined. We’ll explore tools like visual studio, Storage emulator, and quite a few others like Storage, Logic Apps, and Eventgrids. The result will be a fully operational and functional application, built on a serverless paradigm consisting of multiple Azure functions.
This training course will walk you through how to create function apps on Azure, and how to set up visual studio 2017 for local development of functions. This course will then provide steps to create multiple Azure functions and explain all concepts including bindings, triggers, events, integrating with other services, and configuration. Once we understand the important concepts, we will get into hands-on demos implementing scenarios related to Azure functions. Further on, we'll explore how we can use Azure Storage blobs, queues, tables, CosmosDB, Service Bus, event hubs, Github, Scheduling, along with Azure functions. We will also use Visual Studio for development of Azure functions and its deployment to cloud. You will learn about Azure function proxies and the latest Durable functions using hands-on Demos. Finally, we will create a complete application comprising of multiple functions, all integrated with each other to form and implement comprehensive, cohesive functionalities.
We will also get into testing, troubleshooting, and best practices for implementing and deploying Azure functions.
