Ding Dong it’s Azure Front Door

As part of my Azure feature series lets take a look at Front Door.

What is it?

Azure Front Door Service provides a scalable and secure entry point for fast delivery of your global web applications.

This essentially means that by placing a Front Door ahead of your application you gain increased performance and security.

Getting started

Setting up is straight forward, if you’d like to test Front door and you don’t have an application to use you can setup a sample web app using my previous article here .

First click New Resource in your Azure Portal and search for Front Door, then click Create

Choose your subscription ,resource group and Azure region. then click Next: Configuration

Now it’s a simple three step process

  1. Add a frontend host
  2. Configure backend pools
  3. Configure routing rules

Adding a Frontend Host

Click the + icon in the corner of the frontend host window and give you frontdoor a name and enable Session Affinity if required.

Adding a Backend Pool

Next click the + icon in the corner of the backend pool window. Give your pool a name, configure your load balancing and then click on add a backend.

Backend hosts can be various types in this example we are using an App Service, you can also use Cloud Service, Storage, Storage(Classic) or Custom host. Select your Subscription and backend host and click add and then add again.

Adding Routing Rules

Next click the + icon in the corner of the routing rules window. Give your rule a name, decide if it must accept HTTP or HTTPS or both and select your frontend host. Next configure the forwarder and enable caching if required, if your app uses lots of static content this will drastically improve load time performance, then click add.

click Review + Create and then Create

You should now be able to access your application using the frontdoor URL available on the top right hand side of the Overview blade.

How much better is it?

Below we have two speed test results one for my webapp API and one for my Frontdoor we can see a 53% improvement from 1.33 seconds to 710 milliseconds.

The tale of the Bakery that helped me test Azure Application Insights

If you ever need to test Application insights or any of the other Azure features that need an application such as Front Door there is a simple way to create a test application baked into Azure.

In your Azure portal simple click on “New Resource” and search for Bakery and click Create

Now give the App a name, choose your subscription, resource group and an applicable App Service Plan. Remember the more robust the plan the higher the cost, there is a free limited Tier available called F1 Shared. Then click Create.

After a few minutes your application will be deployed and ready for use with Azure Features. select App Services in your Azure Portal and then click on your Bakery Application

You can find the URL for your new site at the top right of the Overview blade.

Browsing the URL you should see the below site.

For an extra tip if you need the site again you can turn it off instead of deleting it to save some costs. Just press stop in the application overview.

Create interactive reports with Azure Monitor workbooks

A new feature in Azure, Workbooks combine text, Analytics queries, Azure Metrics, and parameters into rich interactive reports. 

For those of your familiar with SCOM, think of workbooks as a pre-bundled set of metrics similar to the dashboards you are already familiar with. It offers a simple method to share useful dashboards which can also be copied and exported.

Let’s dive right in.

So how do I find them?

Simply navigate to Monitor in the Azure portal and click on Workbooks, currently in preview at the time of this article.

Whats available currently?

There are several pre-build templates out of the box as well as a GIT available as a repository for additional templates.

VM Metrics Example

Below are several sample outputs of the various workbooks, not only do they look good but they also contain rich useful information on every object in your subscription that is metric enabled.
