If you have a blog running at blog.mycompany.com, that is not going to be as effective for SEO as if the blog were at mycompany.com/blog. You want your primary domain getting the credit. But it’s also not ideal to have a separate subfolder if you have two different services (blog and main product).
So the best solution is to reverse proxy so that internet traffic hits /blog, but the worker is actually forwarding the traffic to your internal service.
