Remember from the previous sections that we used App Service to run our WordPress application. Here we will review
 additional information about our app and explore some of the options provided for configuring your website.

How about we investigate a portion of this data.

 1. Open the Azure portal  .
 2. Select Dashboard from the navigation menu on the left to access the list of all resources on your subscription.
  You may need to click on the menu icon to see the navigation options.

3. Select the App Service with the name you chose in the previous exercise  .

4. If Overview is  not selected, the App Service overview is displayed by default.

5. Scroll down the overview view until you can see the graphics for your newly created website. These
 graphs provide statistics on the number of requests received by your website, the amount of incoming
and outgoing data, and the number of errors encountered on the site. The information shown here is near
 real-time data and provides a quick overview of your website performance. Site performance issues are
 reported as early warnings in these graphs.

What is the scale?

Imagine you are distributing your website and the site is popular. By looking at the graphs in the overview,
 you realize that your site is not able to effectively manage all requests it receives. To fix the problem, you
 will need to increase the hardware capacity of the server.

Scale refers to adding network bandwidth, memory, storage, or processing power to increase performance.

You  may have heard the terms increasing scale  and  extending scale .

Increasing scale or vertical scaling means increasing the memory, storage, or processing power of the existing
 virtual machine. For example, by adding memory to a web or database server, you can make it run faster.

Scaling or scaling horizontally means adding extra virtual machines to power your application. For example,
 you can create multiple virtual machines configured in the same way and use a load balancer to share the
workload between those machines.


The cloud is flexible. If you temporarily increase the scale or scale you need to expand your deployment  can
 be scaled back  or  you can narrow down the scale . Scaling down and scaling down can help you save money.
Azure Consultant  and  Azure Cost Management  are two services that help you improve cloud spending. Using
 these services, you can identify where you are using more than you need and then scale down to the capacity
 you actually use.

When you have more time, you can easily go through each section and explore the various options provided.

Changing the App Service configuration

Application Services has many configurable options and these options are grouped into functional sections.

The first section displays a group of general options that you can access to get a view of the status of your
application. However, each of the sections below provides additional functions and information.

For example, the  Settings  section provides access to configure various aspects of the App Service such as
application settings, backups, custom domains, TLS / SSL settings, and options to scale up the application's

Increase the scale of your App Service
Service's your App  Settings  in the configuration partition  boost Scale (App Service Plan)  Select.


Note that there are three workload categories to choose from in the configuration pane. These three
 categories make it easy to decide on the type of workload we will run. 1 TABLE Category Description
 Development / Test This category is ideal for less demanding workloads. This category focuses heavily
 on providing shared infrastructure. In this category there are additional features available in the App
 Service application. For example Custom domains / SSL and manual scaling. Manufacturing This
category is ideal for more demanding workloads. In this category, you'll also see newly added features
 such as staging slots, daily backups, and traffic manager. Isolated This category is ideal for workloads
that require advanced networking and deep scaling. Below each category is given pricing tiers that will
allow us to scale the resources available to our App Service. These pricing tiers give us access to the
additional features mentioned above. We   'll leave the configuration at the F1 tier, but note that if your
 app load changes you can go to this pane to make scaling adjustments to your App Service. Let's now
 review how to use Cloud Shell to configure Azure resources such as App Service.
