In part one, we introduced the duality of observability, controllability. As a reminder, observability is the ability to infer the internal state of a "machine” from externally exposed signals. Controllability is the ability to control input to direct the internal state to the desired outcome. So observability is a loop problem. And we need to stop treating it as the end state of our challenge in delivering performant, quality experiences to our users and customers.

The waves of change are certainly upon us and businesses are being forced to adapt at a record pace. Current world events have caused a jarring shift in all aspects of our lives, accelerating major changes in how we live and work. An unprecedented number of people are now working from home.

IT managers needed to get data on a set of standard metrics, from a handful of tools.

Over the past few months, we published a number of articles showing how to snap desktop applications written in different languages – Rust, Java, C/C++, and others. In each one of these zero-to-hero guides, we went through a representative snapcraft.yaml file and highlighted the specific bits and pieces developers need to successfully build a snap. Today, we want to diverge from this journey and focus on the server side of things.

You can utilize an SSL checker to troubleshoot the common SSL errors and vulnerabilities if you have installed an SSL certificate before. There is a plethora of tools you can choose from.

You simply must submit the domain name or IP address and the port number it requires to examine your website’s configuration and security.

Remote access to intranets and otherwise restricted areas was always a challenge. On one hand, it’s desirable to re-create convenient and familiar access to the same resources; on the other hand, there are many issues, starting from ensuring security and access reliability The same is related to monitoring. If a network’s devices should be monitored, there always should be access to them; thus, there’s a separate task of monitoring accessibility. Below are several guidelines.

“Remember that guy that gave up? Neither does anybody else.” Progress on the new Monitive has been slow as a snail in a marathon, but nevertheless the progress was there. Since the last update last year, a lot has been going on, and one day I woke up and just decided to write, even if small updates. Not only because Monitive is about transparency, but because I love writing.

Apache Flink is an open source framework, written in Java and Scala, for stateful processing of real-time and batch data streams. Flink offers robust libraries and layered APIs for building scalable, event-driven applications for data analytics, data processing, and more. You can run Flink as a standalone cluster or use infrastructure management technologies such as Mesos and Kubernetes.
