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).

You’ve probably been using Puppet Forge modules to manage bits in your infrastructure for years. If you’re like most of us, you’ve gradually added more modules and maybe you’ve lost track of exactly what some of them do and on what nodes they’re declared. You may even suspect that you have modules installed that you haven’t actually used in years…. only you’re not quite certain which modules those might be. I am certainly guilty of this!

We have seen a rapid increase in the development pace of product development in the last few years. As a company, you never stop improving your processes. Successful organizations find different ways to optimize the release process to accelerate their product development cycles. Growing companies, especially those with complex products with many integrations, often struggle to keep pace with the growing complexity of processes.

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.

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.

To many engineers, the idea that you can accurately and comprehensively track your application's user experience using just a few simple metrics might sound far-fetched. Believe it or not, there are four metrics that aim to do just that. They're called the four Golden Signals and should be a core part of your observability and reliability practices.
