I’d be highly surprised if G’Wullu actually developed and host Warhammer+ directly, they’ll most likely have contracted the development and ongoing support of the platform to a third party, likewise, they are probably utilizing a cloud service such as AWS for the actual hosting of it too if they have any sense, which if done right will allow them the grow the service easily and deliver to any part of the world (they choose).

Why do I say this?

With Europe/US/Australia that’s realistically three data centers that would be needed if they hosted it themselves, that is a huge cost, in equipment and staff and very slow in terms of scaling the service to demand. With a cloud service that’s comparatively easy to set up and scale. You might think “thing on the internet, accessible anywhere” but the likes of streaming video are very much impacted by the distance the data travels, hence why you need more local servers providing the content.

As for contracting out, I don’t remember seeing any significant increase in hiring on the IT side from them, setting this up would have required a significant team across a range of disciplines. Contracting out has a number of advantages, while it might seem expensive (when you see day rates) it’s much lower risk and provides more on-demand access to resources, without needing to maintain an expensive array of staff. Secondly, G’Wullu is not known for paying well, the IT sector is very competitive, hiring and keeping good staff if you don’t pay them well is hard.
