Azure Cloud Service classic for net core or .net 5

Question

I have an existing "Azure Cloud Service (classic)" project that runs our cloud services. I'm currently trying to migrate everything over to .NET 5, but it seems the cloud service project doesn't have the ability to use .NET 5 or even Net Core 3.1. The only options are from the full .net framework. So I was trying to find an alternative to the old cloud service project that supports .NET5/Net Core 3.1. Does anyone know of one or a way to add net core services to azure cloud service (classic) projects?

Answer 1

Azure Cloud Service (classic) is based on the older platform-as-a-service (PaaS) offering from Microsoft and is designed primarily for the .NET Framework. It does not natively support .NET Core or .NET 5, as these newer frameworks require modern runtime environments.

Here’s a breakdown of your options:

---

1. Migrate to Azure App Services

Azure App Services is a modern PaaS solution that fully supports .NET Core, .NET 5, and newer frameworks. It provides many features similar to Cloud Services (classic), including:

• Automatic scaling
• Continuous integration and deployment
• Custom domains and SSL
• Support for Windows and Linux environments

Steps to migrate:

1. Refactor your cloud service project to a .NET 5/.NET Core application.
2. Deploy it to Azure App Services using Visual Studio, Azure CLI, or Azure DevOps.

2. Migrate to Azure Cloud Services (extended support)

Azure Cloud Services (extended support) is a newer version of the classic Cloud Services model and offers better support for modern frameworks, including .NET Core and .NET 5.

Key benefits:

• Supports the Azure Resource Manager (ARM) deployment model.
• Includes enhancements like improved security, reliability, and scalability.
• Works well with modern .NET runtimes.

Steps to migrate:

1. Update your project to .NET 5/.NET Core 3.1+.
2. Use Azure Resource Manager templates to configure the deployment.
3. Migrate your application using tools or manual configuration.

3. Migrate to Azure Kubernetes Service (AKS)

If your application architecture involves microservices or you need fine-grained control over your environment, Azure Kubernetes Service (AKS) is a great option. AKS supports .NET Core, .NET 5, and any runtime compatible with containers.

Steps to migrate:

1. Containerize your .NET 5 application using Docker.
2. Deploy the container to AKS.
3. Configure scaling, networking, and monitoring as needed.

---

4. Use Azure Virtual Machines (if necessary)

If your application requires specific dependencies or configurations that are not supported by PaaS solutions, you can deploy it to an Azure Virtual Machine. However, this option is less automated and involves managing the underlying infrastructure.

Steps to migrate:

1. Deploy your .NET 5 application to a Windows or Linux VM.
2. Use Azure Pipelines or other CI/CD tools for deployment.

Recommended Approach

For most scenarios, Azure App Services or Azure Cloud Services (extended support) is the easiest and most efficient migration path. If you need additional control or scalability, consider AKS.
