DNS (Domain Name System) servers translate standard language web addresses to their actual IP addresses for network access. DNS response time is the time it takes a Domain Name Server to receive the request for a domain name’s IP address, process it, and return the IP address to the browser or application requesting it. When it comes to DNS response times, the lower the better, and generally values less than 100ms are considered to be in the acceptable range (depending on the application).

In computing, virtualization is the creation of a virtual — as opposed to a physical — version of computer hardware platforms, storage devices, and network resources. Virtualization creates virtual resources from physical resources, like hard drives, central processing units (CPUs), and graphic processing units (GPUs). By virtualizing resources, you can combine a network of resources into what appears to users as one object.

Privacy enhancing technologies and confidential computing are two of my favorite topics to talk about! So much so that I am writing this blog post on a sunny Saturday afternoon. But wait, what’s that I hear you murmuring? “What is confidential computing? And how does it affect me?” Those are two very good questions.
