Choose an Azure compute serviceAzure offers many ways to host your application code. The term compute refers to the hosting model for the computing resources that your application runs on. The following flowchart will help you to choose a compute service for your application. If your application consists of multiple workloads, evaluate each workload separately. A complete solution can incorporate two or more compute services. Choose a candidate serviceUse the following flowchart to select a candidate compute service. Definitions:
The output from this flowchart is a starting point for consideration. Next, perform a more detailed evaluation of the service to see if it meets your needs. This article includes several tables that can help you to make these tradeoff decisions. You might find that the initial candidate isn't suitable for your particular application or workload. In that case, expand your analysis to include other compute services. Understand the basic featuresIf you're not familiar with the Azure service selected in the previous step, read the overview documentation to understand the basics of the service.
Understand the hosting modelsCloud services, including Azure services, generally fall into three categories: IaaS, PaaS, or FaaS. (There's also SaaS, software-as-a-service, which is out of scope for this article.) It's useful to understand the differences. Infrastructure-as-a-Service (IaaS) lets you provision individual VMs along with the associated networking and storage components. Then you deploy whatever software and applications you want onto those VMs. This model is the closest to a traditional on-premises environment, except that Microsoft manages the infrastructure. You still manage the individual VMs. Platform-as-a-Service (PaaS) provides a managed hosting environment, where you can deploy your application without needing to manage VMs or networking resources. Azure App Service and Azure Container Apps are PaaS services. Functions-as-a-Service (FaaS) goes even further in removing the need to worry about the hosting environment. In a FaaS model, you deploy your code and the service automatically runs it. Azure Functions is a FaaS service. There's a spectrum from IaaS to pure PaaS. For example, Azure VMs can autoscale by using virtual machine scale sets. This automatic scaling capability isn't strictly PaaS, but it's the type of management feature found in PaaS services. In general, there's a tradeoff between control and ease of management. IaaS gives the most control, flexibility, and portability, but you have to provision, configure and manage the VMs and network components you create. FaaS services automatically manage nearly all aspects of running an application. PaaS services fall somewhere in between.
