Creating an Azure Web App

Creating an Azure web app is simple, and the process can be accomplished in just a few steps. You can connect to resources on your virtual network, secure the back end tier, and configure VNet integration. After you complete these steps, you can create an Azure web app and configure it for use.
Create a web app

Using Azure Web App, developers Bonuses can create a web app that runs in the cloud without any worry about maintaining a data center. The platform allows developers to build mobile apps, API apps, and web apps. It provides a host for web apps as well as services to help developers manage their applications.

There are several things to keep in mind while deploying a web app using the Azure portal. Firstly, your web app needs to be secure. This can be done by integrating your app with services like Application Gateway, which will provide security to your application. Also, you need to make sure your app is scalable and capable of scaling up or down as needed.

The Azure Monitor also helps in observing your application and provides application insights. It provides full observability into your application, and helps you test how well your application works. The Azure app service also offers a load balancer, which helps you manage the costs of your infrastructure.

Aside from managing infrastructure, the Azure App Service also manages the middleware components and runtime components of your application. This includes the essentials, such as databases and web server, along with critical patches and updates. This is a useful way to keep your application up to date without having to worry about maintaining a data center. The Azure App Service also offers high availability and auto scaling, allowing your application to grow and shrink as needed.

You can create a web app using the Azure portal by navigating to the Overview blade of your web app. Here, you can see a list of the applications that are currently in use, as well as the latest errors that have occurred during the deployment process. You can correct any errors using the Review + Create tab.

The Azure portal now also supports the integration of VNets, allowing content authoring users to work within a corporate network. VNets are also a good way to connect your web app to the cloud, as they provide you with a private link to the Azure portal.
Connect to resources in your virtual network

Using the Azure Virtual Network, you can integrate your web apps with Azure services and securely connect to resources. You can also filter network traffic to ensure your apps are protected from outside threats. If you need to communicate with resources on premises, you can also use the Azure VPN Gateway.

If you want to use Virtual Network peering, you need to have a private IP address. You can then connect virtual networks in different Azure regions. You can also use the Azure resource manager to create a Virtual Network for free.

When you create a virtual network, you have to create subnet objects first. The subnet objects are used for communication between VMs and PaaS services in your virtual network. Each subnet has a set of service endpoints that limit access to Azure service resources. This is done by setting up a route table to define the destination.

For each subnet, you can set up a Network Security Group to protect the subnet and filter traffic to and from it. A Network Security Group contains a set of default security rules that restrict traffic into and out of the virtual network. These rules are used to protect each layer of an application. You can also use constrained security rules to protect each layer of an application. These rules can be defined as access lists, access lists with multiple inbound and outbound security rules, or access lists with multiple inbound and outbound policies.

You can also configure a public Load Balancer to send traffic to an Azure resource. For example, you could configure a Load Balancer to send traffic to your Web App from your subnet. The traffic would then be encrypted and routed through the interface based on customer-defined policies.

To configure a Virtual Network, you can use a command called New-AzVirtualNetwork. The command uses a -Subnet parameter to create a subnet. It also uses commas to separate subnets.

You can also use a Virtual Network Gateway to create connectivity between your subnet and other networks. The Virtual Network Gateway is located on the boundary of your VNet subnet. You can also use a User Defined Route to send traffic to a different VNet.
Configure VNet Integration

Using VNet Integration, a web app can push outbound traffic to a private VNet. This may be useful for sending traffic via an egress controller or sending outbound traffic to an Azure VM. The VNet Integration feature also allows users to configure a virtual network gateway. This gateway automatically adds a gateway subnet to the virtual network.

The vNet Integration feature is not a perfect fit for every situation. Some applications require a dedicated subnet or subnets. For example, each ASP may require a dedicated subnet. On the other hand, a web app may only require a private endpoint. In such cases, a web app is best served by a Premium SKU.

The Azure portal has a variety of tools to configure and manage the various Azure services. The vNet Integration feature is one of the many. The portal has a list of the vNet Integration subnets along with their corresponding IP addresses. Users can select an existing subnet or create a new one. The portal also shows the "Connected" status for web apps.

The portal also allows users to configure a network gateway to default site. This feature is useful for enabling forced tunneling. To configure a network gateway to default site, users must select the virtual network address space, as well as a route. The portal also shows users the most useful routes to select from.

The Portal also has a screen for regional vNet integration. This is a newer flavour of VNet integration. It may be best suited for larger deployments. This screen allows users to view the various subnets within a region. Selecting the most relevant subnet can be tricky. Alternatively, users can create a new subnet and configure it to the appropriate subnet type. This is a simpler solution.

The portal also features a screen for the vNet's best features. This screen displays the most relevant features for a given region. The screen also has a number of links to related articles. The link to the right will allow users to learn more about the various Azure services.
Secure the back-end tier

Whether your back-end tier of your web app is on Azure or on-premises, it's critical that you protect your back-end services from DDoS attacks. This is particularly true for larger enterprise systems that are built up of multiple interconnected services. A good way to do this is to use Azure Front Door, a global scalable entry-point for enterprise applications. Azure Front Door provides a high-performance HTTP(S) load balancer and a scalable application layer caching infrastructure.

Azure Front Door uses a combination of weighted traffic and network latency to prioritize traffic. This means that a primary application receives more traffic than a secondary application. It also supports content caching and SSL offloading.

When using Front Door, you must create an IP ACL for your back-end. This IP ACL must be set to a specific value of the X-Azure-FDID header, which is included in each request.

You can then restrict traffic to that specific value. This can be done for diagnostic or development purposes. You can also restrict traffic to a specific IP range.

Azure Front Door is highly recommended for use with App Service. It can secure your API and Logic Apps and provides built-in DDoS protection. It also supports SSL offloading and AnyCast routing.

The application can be made available in the public multi-tenant offering. In this case, you will need to configure Virtual Network Integration. You can do this manually or use the Azure CLI.

When deploying your App Service into a subnet within your Azure Virtual Network, you will need to configure DDoS Standard. DDoS Standard is a set of security features that protects your App Service from attacks that are directed at the network resource in front of it. It can also be configured to learn normal traffic patterns and detect unusual behavior.

Azure Front Door offers many other features, including Application layer processing, SSL offloading, and application layer caching. It can be used in conjunction with Traffic Manager to improve global connectivity and provide application layer security. It also supports AnyCast routing and SSL offloading, which can help to improve performance of your App Service for remote clients.
