Every year the internet grows vastly in the number of users, servers, websites, e-mail addresses, web applications, social networks, and the web traffic generated between them. Here are some internet statistics as of Q3 2020.

A critical Active Directory vulnerability (CVE-2020-1472) has been making headlines for being the most notorious elevation of privilege bug because it can affect all computers and domain controllers in an organization. This high-risk vulnerability, dubbed Zerologon, gives threat actors easy, instant access to domain controllers without requiring any additional privileges. This attack does not even require a user to be authenticated; the user just needs to be connected to the internal network.

Terraform is an increasingly popular infrastructure-as-code tool for teams that manage cloud environments spanning many service providers. New users are often drawn to Terraform’s ability to quickly provision compute instances and similar resources from infrastructure providers, but Terraform can also manage platform-as-a-service and software-as-a-service resources.

There are a lot of tools, apps and services. If you’ve been following Product Hunt, you already know that startups and new apps are being launched every single day. A startup these days is so common that even high-school kids are doing it. There are endless rivers of guides, books and knowhow on how to do it, and since most startups have some sort of product or service, there might be an app for pretty much anything you might think of.

A few months ago, I blogged about memory-mapping of full chunks of the head block from disk. The feature, which was introduced in Prometheus v2.19.0, brings down memory usage and restart time. Additionally, there’s another Prometheus feature in progress that snapshots in-memory data during shutdown for faster restarts; it’s expected to cut down the restart times by a big factor.

In this article, you will learn how to monitor kube-proxy to ensure the correct health of your cluster network. Kube-proxy is one of the main components of the Kubernetes control plane, the brains of your cluster. One of the advantages of Kubernetes is that you don’t worry about your networking or how pods physically interconnect with one another. Kube-proxy is the component that does this work.
