What is your most preferred programming language for backend server development?

We’re currently exploring options to implement an iPXE-based WinPE deployment solution in Microsoft Azure. Our goal is to streamline OS provisioning for virtual machines using cloud-hosted boot scripts and WinPE images, ideally over HTTP/S for performance and flexibility. Key requirements: Must support iPXE booting in Azure (via ISO, custom VM image, or chainloading). Ability to host and serve WinPE images securely (e.g., via Azure Blob Storage or web server). Cyber Essentials Plus compliance is essential, as we operate in a regulated environment. Preferably a UK-based provider with experience in secure cloud deployments and endpoint provisioning. We’ve looked into solutions like 2Pint Software’s iPXE Anywhere, but we’re open to other vendors or managed service providers who can assist with setup, integration, and ongoing support. Has anyone implemented a similar solution or worked with a provider who meets this criteria? Any recommendations or lessons learned would be greatly appreciated.
