Hands-On Azure for Developers

Azure WebJobs

Azure WebJobs are one of the underlying features of Azure App Service. They allow for the easy running of so-called "jobs" using different intervals, or even running them infinitely. They are very flexible and provide a special SDK, so users can work with them efficiently and quickly.

The following topics will be covered in this chapter:

  • How to create Azure WebJobs
  • Working with different trigger types (continuous and triggered)
  • Using different file types for WebJobs

Technical requirements

To perform exercises from this chapter, you will need the following:

  • Access to an Azure subscription
  • Visual Studio 2017 with Azure development workload installed

Creating WebJobs

Working with WebJobs is much simpler than working with App Services, as this is a much easier service to configure and use. In fact, there are two ways of working with them:

  • Using Azure Portal and deploying a job manually
  • Using Visual Studio to develop and deploy it manually

What is more, you can leverage the WebJobs SDK to prepare an application triggered by an external service. This will be covered at the end of this chapter, and will be an excellent introduction to Azure Functions, described later in this book.

Creating and deploying WebJobs in Azure Portal

The easiest and quickest way to start working with WebJobs is to create a custom console application, perform an action, and then deploy it using...

Using different file types for WebJobs

When you are working with WebJobs, you are not limited to using EXE files. Currently, this service supports the following applications:

  • Windows executables (.exe, .bat, and .cmd)
  • Powershell (.ps1)
  • Bash (.sh)
  • Python (.py)
  • PHP (.php)
  • Node.js (.js)
  • Java (.jar)

As you can see, the preceding list is quite similar to the supported languages in App Services. This should be understandable now, as you have learned that WebJobs are in fact an integral part of Web Apps in Azure. Let's try something practical—we will deploy a simple Node.js application, which will publish to Azure as a WebJob.

Creating and deploying a Node.js application as a WebJob

JavaScript is one of the most popular...

Summary

As you have seen, Azure WebJobs are a really helpful and useful feature of App Services that let you quickly develop jobs running either continuously or triggered on schedule. They start to shine when you have a working web app, which could be used to host them and execute many different actions asynchronously (such as generating a report or reading a queue, which will feed your application's database later). Thanks to the support of different programming languages, you do not have to limit yourself to only one particular platform. Last but not least, they are a great introduction to Azure Functions, which are one of the most popular services in Azure and extend the current possibilities of WebJobs even further. In Chapter 3, Deploying Web Applications as Containers, you will learn about deploying Web Apps as containers, what extends even more the capabilities of...

Questions

  1. Can you run WebJobs using the Free or Shared tier?
  2. What run modes does WebJobs currently supprt?
  3. Can you run a Java application using WebJobs?
  4. How can you ensure that runtime will find your job starting file?
  5. Can you publish a WebJob containing more than only one file? If so, how can you do that?
  6. How can you ensure that a WebJob will not be scaled out to multiple instances?
  7. Can a WebJob access the application settings of the App Service that hosts it?

Key benefits

  • Get up and running with the development aspects of Azure cloud
  • Build fault-tolerant and scalable applications on Azure
  • A practical, developer-centric guide for Azure developers

Description

Microsoft Azure is one of the fastest growing public cloud service providers in the market currently, and also holds the second highest market share after AWS. Azure has a sophisticated set of services that will help you build fault-tolerant and scalable cloud-based applications. Hands-On Azure for Developers will take you on a journey through multiple PaaS services available in Azure, including App Services, Functions, and Service Fabric, and explain in detail how to build a complete and reliable system with ease. You will learn about how to maximize your skills when building cloud-based solutions leveraging different SQL/NoSQL databases, serverless and messaging components, and even search engines such as Azure Search. In the concluding chapters, this book covers more advanced scenarios such as scalability best practices, serving static content with Azure CDN, and distributing loads with Azure Traffic Manager. By the end of the book, you will be able to build modern applications on the Azure cloud using the most popular and promising technologies, which will help make your solutions reliable, stable, and efficient.

Who is this book for?

Hands-On Azure for Developers is for developers who want to build highly scalable cloud-based applications on Azure. Prior knowledge of Azure services will be an added advantage.

What you will learn

  • Implement serverless components such as Azure functions and logic apps
  • Integrate applications with available storages and containers
  • Understand messaging components, including Azure Event Hubs and Azure Queue Storage
  • Gain an understanding of Application Insights and other proper monitoring solutions
  • Store your data with services such as Azure SQL and Azure Data Lake Storage
  • Develop fast and scalable cloud applications

Das Buch liefert einen schönen Einstieg in die wichtigsten Punkte mit Azure Develoment. Es sind wirklich Hands-On, also Beispiele, denen man auch durch die vielen Screenshots gut folgen kann. Auch hier gilt zu bedenken, dass das Buch von 2018 ist, also Azure an einigen Stellen ein anderes Erscheinungsbild hat oder Funktionen umgezogen sind. Für den neuesten Stand kann man den Microsoft Learn Path zu Examen AZ-204 hinzuziehen. Die Tip-Sektion im Buch hat mir besonders gut gefallen, insgesamt schöne Gliederung und hilfreiche Beispiele. Wenn man nicht selbst tippen will, sind die Beispiele auf der Webseite zum Buch downloadbar.

Well written, example code snippets/templates to get your started and most importantly screenshots (probably why the book is over 500 pages).

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
