Each organisation is different, some has dedicated teams to manage and provision resources. But if you were to manage them your self as a developer, either you login to Azure Portal and create necessary resources yourself or you CI/CD (Infrastructure as a code) do it as part of the release.
When you work with Azure Functions, you can use Azure table storage “Static website” to store all your Angular bundles and assets or even a CDN. Then you can set up your proxies.json to serve the files, everything is pretty much the basics.
Create resources automatically using CI/CD, including creating resources such as Storage, Azure Functions, etc.
