Before you start

Before you take a deep dive into our documentation, please take a moment to learn some basic information about the technology and tools we are using. It might help you to understand the documents better and faster.

As a cloud forming company, we are trying to leverage every trending tool and technology that would enable continuous delivery at high velocity.

And with that being said, our guiding principles are DevOps and SRE(Site-Reliability-Engineering). DevOps is a cultural philosophy that injects simplicity and open minded approach to company ranks. Together with SRE, which provides guidelines to achieve sustainable high service reliability and availability, they work as a modern strategy for companies to deliver their goals at fastest pace possible.

This video could provide a quick introduction to both. There are many books, videos and inspirational presentations describing DevOps and SRE from all angles.

There is a popular phrase that DevOps is a set of tools, which is one of the truths about DevOps. So let's introduce some most used technologies and tools we use in Pan-net.

List of tools we use

In Pan-net and in DevOps culture generally, we rely heavily on new technologies and tools that improve our efforts in service delivery by leaps and bounds. Here's a categorized list of most used and needed tools/technologies.
