As complexity of systems and applications continue to evolve and change, the number of metrics that need to be monitored grows in parallel. Whether you’re on a DevOps team, an SRE, or a developer building the code yourself, many of these components may be fragmented across your infrastructure, making it increasingly difficult to identify the root cause when experiencing downtime or abnormal behavior.

IPv4 and IPv6 are the two versions of IP. IPv4 was first released in 1983 and is currently widely used as an IP address for a variety of systems. It aids in the identification of systems in a network through the use of an address. The 32-bit address, which may store multiple addresses, is employed.

It has been a while since I have been excited to write about encrypted tunnels. It might be the sheer pain of troubleshooting old technologies, or countless hours of falling down the rabbit hole of a project’s source code, that always motivated me to pursue a better alternative (without much luck). However, I believe luck is finally on my side.

There’s something that humans and machines have in common, and no, it’s not the disappointment suffered by the final season of Game of Thrones, or, well, at least not only that. What we have in common is that we need protection. You know, animals need it too, and plants, but if you’ve gotten this far, it seems that you’re interested in computers, networks and all these pretty modern “geek” things, so today we’ll talk about that kind of protection.
