Modernizing Web Apps with Azure App Service: Success Stories
Hello Everyone! Welcome back from ARTIFICALAB LTD! Today, we will be talking about modernizing web applications with the new feature of Microsoft Azure Cloud: the Azure App Service!
Indeed, Azure App Service can offer a fully managed environment for building, deploying, and scaling web apps, as well as supporting numerous programming languages and frameworks.
The best part of Azure App Service is such that it has the capabilities to perform auto-scaling, load balancing, and seamless integration with other Azure service. In this article, we will explore the success stories of various industries that have leveraged Azure App Service to enhance performance, security, and operational efficiency.
"Traditionally, web developers have to setup their own deployment environment in a private server, with complex setup technical requirements. Not only that, scaling up and scaling out resources could come with huge challenges too. However, with the introduction of Azure App Service, developers can now easily setup their web apps in Azure App Service Plan, choosing the perfect App Plan Pricing Tiers, as well as considering for scalability, SSL offloading and high availability issues. Web Apps become more secured than ever, even in the face of major cyberattacks and disasters!"

Concepts of Azure App Service
Before we start discussing about the success stories of businesses with Azure App Service, we first need to understand the concepts of Azure App Service and its mechanisms. So let's explore as below:

App Service Plan:
This is the first concept you need to know. Indeed, it defines the region, features, and scaling options for your web apps. It determines the compute resources available to your app. You can choose from various pricing tiers based on your needs.
If you are a new learner in Azure Cloud, you need to keep in mind that the Azure App Service Plan includes the following:
- Operating System (Windows, or Linux)
- Region (West US, East US, etc.)
- Number of VM instances for your plan
- Size of VM instances (Small, Medium, Large)
- Pricing tier (Free, Shared, Basic, Standard, Premium, PremiumV2, PremiumV3, Isolated, IsolatedV2)
Scaling:
Azure App Service offers both manual and automatic scaling options. You can scale up (increase the size of your instances) or scale out (increase the number of instances) to handle varying loads.
To understand about this concepts a little bit more, we have attached the following figures for your reference!

Deployment Slots:
These allow you to create different environments (e.g., staging, production) for your web app. You can swap slots without downtime, making it easier to test and deploy updates.

Custom Domains and SSL:
You can configure custom domains and secure your web apps with SSL/TLS certificates.

Continuous Integration and Deployment (CI/CD):
Azure App Service integrates with popular CI/CD tools like GitHub, Azure DevOps, and Bitbucket, enabling automated deployment workflows.

Azure App Service Plans that you should know!
Referencing from Microsoft official documentation, we have shared a range of pricing tiers that are available on the Azure App Service Platform.
Free and Shared Plans:
These are intended for trials, experimentation, and learning. They run on shared resources and are not recommended for production workloads.

Basic Plan:
Suitable for small-scale applications, this plan offers dedicated resources and basic features.

Standard Plan:
This plan includes more advanced features like auto-scaling, daily backups, and custom domains. It is ideal for production workloads.

Premium Plan:
Designed for high-traffic applications, the Premium plan offers enhanced performance, additional scaling options, and advanced features like isolated environments.

Isolated Plan:
This plan provides maximum isolation and security by running your apps on dedicated Azure Virtual Networks. It is suitable for mission-critical applications requiring high security and compliance.
Networking Architecture in Azure App Service
Azure App Service provides robust networking features to control inbound and outbound traffic:
Multi-Tenant Service:
Hosts App Service plans in Free, Shared, Basic, Standard, Premium, PremiumV2, and PremiumV3 pricing SKUs. These plans are hosted in a multi-tenant environment, meaning multiple customers share the same infrastructure.
Single-Tenant Service (App Service Environment - ASE):
Hosts Isolated SKU App Service plans directly in your Azure Virtual Network. This provides enhanced security and isolation, suitable for applications with stringent compliance requirements.
Networking Features in Azure App Service
Virtual Network Integration:
Allows your app to access resources in your Azure Virtual Network.

Private Endpoints:
Enables secure access to your app over a private IP address within your virtual network.

Hybrid Connections:
Facilitates connectivity between your app and on-premises resources.

Access Restrictions:
Allows you to define rules to restrict access to your app based on IP addresses or virtual network subnets.

Limitations in Azure App Service
While Azure App Service offers many benefits, it also has some limitations:
Resource Constraints:
Lower-tier plans (Free, Shared, Basic) have limited CPU and memory resources, which may not be sufficient for high-traffic or resource-intensive applications.
Cold Start Latency:
Apps may experience latency during cold starts, especially in lower-tier plans. This can affect the user experience if the app is not frequently accessed.
Limited Control:
As a PaaS offering, Azure App Service abstracts much of the underlying infrastructure, which can limit control over specific configurations and optimizations.
Networking Limitations:
While App Service provides robust networking features, there are still limitations in terms of network isolation and custom configurations compared to IaaS solutions.
Best Practices for Azure App Service
For Web App Developers, it is essential to have some knowledge about common best practices for deploying Web App on the Azure App Service.
Colocation:
Ensure that your web app and its associated resources (e.g., databases, storage) are in the same Azure region to reduce latency and avoid additional data transfer costs.
Certificate Pinning:
Avoid hard dependencies on default wildcard TLS certificates. Use custom domains and provide custom TLS certificates for applications that rely on certificate pinning.
Auto-Healing:
Configure auto-healing to automatically mitigate issues such as high memory or CPU usage. This can include actions like recycling the worker process or sending notifications.
Use Deployment Slots:
Deploy new builds to staging slots first to validate changes and perform smoke tests before swapping to production.
Monitor and Optimize:
Regularly monitor your app’s performance and resource usage. Use Azure Monitor and Application Insights to identify and address bottlenecks/
