What is Azure API App, features and compare with Web App
Ashok Nalam
With Azure API App, we can easily build, deploy and consume API on the cloud without managing underlying infrastructure. The key features of API Apps – authentication, CORS and API metadata.

Features of Azure API App 

1. Faster deployment of scalable Rest API’s 
2. Support of Authentication with Azure AD and call Microsoft API’s
3. Consume APIs with CORS support
4. Swagger Support
5. Develop APIs with .NET, PHP, Node.js, Python or Java
6. Easily integrate with other Azure service like API management, Azure SQL, Logic apps and many more
7. Configure CI/CD to deploy your API’s
8. For Pricing refer to Azure App Service plan pricing. 
9. Secure Platform that scales automatically 
10. Monitor your App, configure alerts and do Auto scaling

Azure Web App vs API App

1. Web Apps is a website which you can see in the browser whereas API is a service used in Web App. E.g: ASP.NET MVC application is Web App having UI with data where Web API return only data via end points for integrations to exchange data.
2. Now API APPs and Web Apps under the umbrella of APP Services if there is no difference, only icon difference in Azure Portal. 
3. If you want to import API definition in Azure API management, you can do only with API App under App service.

Now, all of web, Mobile and API Apps are collectively coming under Azure App Services.

Why to use Azure App Service?
Ashok Nalam
Azure App Service is a full managed Platform as a Service (PaaS) which enables to build and deploy web applications, Restful API’s, mobile back ends without managing underlying infrastructure with the choice of your programming language like .NET, .NET Core, Java, PHP, Python or Ruby. Application can run and scale on both windows and Linux environments.

Below are few features of Azure App service and based on this you can choose the service.

  1. Built-in Auto scale support – App service can be configured to scale up/down or scale in/out automatically based on your usage. Scale up/down increase the cores and RAM where as in/out increases or decreases the number of instances that are running your app.
  2. High Availability – Deploy your apps anywhere in Microsoft global data centers and with the right plan App service provides high availability for your application.
  3. IDE Integration – you can create, deploy and debug your azure app service application using visual studio, visual studio code, Java IDEs’ like Maven, Eclipse, IntelliJ. 
  4. Continuous Integration and Deployment support – In the Azure portal, App service provides continuous integration and deployment with sources like Azure DevOps, GitHub, Bitbucket, FTP or local Git Repo from your local machine. Connect your application with the sources and App service will automatically synchronize your changes in the future. 
  5. Deployment Slots – when you deploy your web app you can use separate deployment slot(staging) instead of production slot to test your changes with standard tier and above. Deployment slots have its own separate host names and you can swap content and configurations between deployment slots including the production slot. The swap operation warms up necessary worker processes to match your production scale with no downtime. 
  6. Authentication – App service provides built-in authentication and authorization capability so your users can login to the App and access data based on the permissions with minimal changes to your code. You can use third party identity providers Microsoft, Facebook, Google, Twitter and GitHub.
  7. Multi language and Framework support – you can develop your application or APIs with .NET, PHP, Node.js, Python or Java of your choice even you can write power shell script to run back ground jobs. Easily manage your apps in App service by writing Power shell or Azure CLI scripts. 
  8. Integrate with other services and SaaS Platforms – Easily integrate with other Azure service like API management, Azure SQL, Logic apps (SaaS connectors) and many more. You can access your on-premises data using Hybrid connection or Azure virtual network configuration with app service. 
  9. API and Mobile scenarios - App service provided CORS support for Rest API’s and supports mobile apps scenarios like authentication, push notifications and offline data synchronization. 
  10. Serverless Functions – you can use Azure App Service to run Azure functions with out managing underlying infrastructure. You will pay only for the compute time when your code is executed.

What tiers does Azure API Management offer?
Ashok Nalam
Azure API management comes in 2 different sets of tiers. 
  1. First one is consumption tier which is built per number of API executions and it is easier to start with even if your application is just picking the API traffic because Microsoft offers one million API executions for free every month. It does not incur any fixed costs. 
  2. The other set of tires are the so-called dedicated tiers( called Developer, Basic, Standard, and Premium) where you are billed on an hourly basis, a fixed price and the offer more features than consumption tiers.
Note – You might incur additional charges for API management when using virtual networks, availability zone, and multi-region writes. 

Azure API management is an azure service so your provisions in the azure cloud and route all the API calls through the azure cloud but Microsoft also offers self-hosted components like API gateway or the developer portal that you can host in other clouds like AWS, GCP or on-premises.

What are the different hosting plans for Azure functions
Ashok Nalam
While creating Azure Functions, we must choose a hosting plan for the App. There are 3 basic plans named App Service Plan(dedicated), Consumption, and Premium plans and all these plans are available in Windows and Linux VM’s.

Let's look at what plan provides which features and based on these features and your needs you can select the right plan. 

ScalingAutomatically based on incoming requestsAutomatically with pre-warmed instances so that no delaysPredictive scaling or Manual
Scale Out Max# instancesWindows - 200
Linux - 100

Windows - 100
Linux - 20-100
Cold startWith Idle scenario, scale goes to 0 and we have latency to scaleWith Pre-warming feature there is no latencyNA - function app runs continuously 
Default PlanYes NoNo
VNET connectivityNoYes Yes
App timeout(Min)5 mins30 mins30 mins
App time out(Max)10 minsunlimitedunlimited
BillingPay only for the time when App runsPay as per runs plus pre warmsPay as per App Service Plan
When to consider
  • Scale automatically
  • Pay only when you run

  • App requires continuous run
  • You need more CPU, memory and high GB seconds than consumption plan
  • More execution time than consumption plan
  • VNET connectivity
  • Want to re-use existing App Service Plan
  • Predictive scaling and cost requirements

Other than these 3 basic plans, we have App Service Environment(ASE) and Kubernetes isolation plans, do refer Microsoft documentation.

As developer, why to consider .NET for Azure functions
Ashok Nalam

As a Serverless solution, Azure Functions provides ready to code environment to developers with Visual studio and Visual Studio Code IDE's. With this, developers are able to focus on piece of code that is important to them. When you get started with .NET Programming for Azure functions, you do not need to setup server or maintain infrastructure by yourself, you get control over the App start up, configuration process  and many of other features out of the box.

As a .NET developer with no change in habits, you can leave current .NET  behaviors like dependency injection and incorporate middleware into your Function App. On top of that Azure Function app make your code available in the cloud with CI/CD with Azure DevOps and Github Actions. You can run your code with highly scalable on demand computer resources and easily integration with other azure services such as Azure storage, Eventgrid, CosmosDB and many more Azure Services.

What are the differences between Azure functions and Azure logic apps
Ashok Nalam
Azure function and Azure logic apps both are serverless workloads. Let's look at a few differences below.

Azure FunctionsAzure logic Apps
Execute event-driven serverless code functions with an end-to-end development experienceAutomate the access and use of data across clouds
serverless compute servicesServerless workflows
Code first approached - imperativeDesign first - declarative
Uses App Insights for monitoringUses Azure Monitor logs and Azure Portal
Managed with Rest API and Visual studioManaged with Azure Portal, Rest API, Visual studio and PowerShell
Execute locally or in cloudRun any where
Lot of binding types and extend your own bindingsLot of connectors or build your own
We can call Azure logic apps from FunctionsWe can call Functions from logic app
Write code for each activity to executeIn built read made actions(app connectors) available to integrate from the collection 

Based on above comparisons and your requirement factors you can choose any of the service.

What is Azure Functions
Ashok Nalam
Azure functions is a logical unit of code that lets you execute your code in a server less environment without worrying about application infrastructure. It provides updated infrastructure and your application runs at a scale automatically whenever there is a load.

You can develop your function code using C#, Java, JavaScript, Powershell, and Python languages of your choice. Package managers like Nuget and NPM are supported so you can use popular libraries in your application logic.

Azure functions are surrounded by triggers and bindings. A function is triggered by a specific type of event. 

Once the functions are developed and deployed to azure, then you can pay per use pricing model. The plans will be App Service Plan, Consumption Plan, and Premium plans.
