In this blog I will show you how to create snapshots of Persistent volumes in Kubernetes clusters and restore them again by only talking to the api server. This can be useful for either backups or when scaling stateful applications that need “startup data”.

When I read Fowler’s new ‘Refactoring’ book I felt sure the example from the first chapter would make a good Code Kata. However, he didn’t include the code for the test cases. I can fix that!

Nicole Forsgren and the Accelerate DORA team has just released the newest iteration of the State of DevOps report. The report investigates what practices make us better at delivering valuable software to our users as measured by business outcomes. Read on for our analysis of the report, and how it can be best put to use.

A major challenge of software development is that our work is by and large invisible. This makes our folklore essential in business matters. Some of our commonly used arguments and visualizations are digital urban legends rather than solid foundations for informed decisions. Here, we’ll go through a few examples and some measures to address our misconceptions.

When you embark on your cloud native journey there will be important choices to make about cloud providers, continuous deployment, environments’ setup and separation. This guide will help you make the right choices by sharing lessons learnt from running cloud native apps in production.

Kubernetes has become the de facto container orchestration platform. When we help clients of different sizes and domains start their cloud native journeys in Kubernetes, we assist them in making sound decisions and technology choices. There is no one-size-fits-all solution when it comes to choosing cloud providers, CI tools, continuous deployment pipelines etc., so it is important to make the right decisions at the start. Failing to do so can be very costly in terms of lost time and money.

Learn how Docker and Kubernetes work and the key benefits they bring. Using real demos, I show how Docker is a great packaging and distribution technology, and how Kubernetes provides a powerful runtime for containerized applications.

In the world of Agile and DevOps we use many figures, charts and diagrams to argue and reason about our world and how we prioritize and make choices. However, at all levels of the organization, we misuse and misinterpret figures. It’s time to be explicit, measure the right things and act on them. Watch this talk from DevOpsDays Zurich in May 2019.

Summer is a great time to catch up on reading, whether you’re at the beach, in a summer house, or cozy at home. If your book backlog is on the short side, don’t worry! We compiled a list of great books for summer reading.

The rising demand for Continuous Delivery and DevOps skills in the job market and the fact that those skills are in most cases not part of the mandatory university curriculum motivates Praqma to share knowledge with the next generation.

At Praqma we believe in knowledge sharing, and we love to teach our technical expertise. Watch this series of videos to learn how traefik reverse proxy works step by step.

Atlassian Software in Kubernetes (ASK) is a unique solution to run Atlassian installations within Kubernetes. It provides an easy to manage system that is highly available, instantly scalable, efficient and reliable. Developed by Praqma, ASK is now going to be open source.

This move sees two Nordic companies that are shaping DevOps in Europe unite. Now we are poised to change the world of software as one company. The company will be fueled by the collaborative and forward-thinking attitudes that has made DevOps as a software-making methodology so successful over the past decade.

This is a conference in Gothenburg for software developers, especially those with some experience of agile and a desire to improve their skills.

Praqma has a long history of accelerating and enabling team productivity using the Atlassian stack. Thanks to the hard work and commitment of our consultants Praqma has now achieved Atlassian Platinum Partner Status.

What testing steps should you include in your Continuous Delivery pipeline? Don’t just string together existing manual processes - use simple, collaborative tools to design something better!

Praqma is proud to announce that we will be part of an exciting EU research project to unlock the benefits of serverless FaaS for the European software industry. RADON (Rational decomposition and orchestration for serverless computing) is funded by the European Union within Horizon 2020.

In the Accelerate book, researchers explain several metrics which they have shown will measure the performance of a DevOps organization, and crucially, drive performance of the organization as a whole. I will explain why this is important, using an analogy with your risk of a heart attack.

Your repositories are cluttered, you’re storing irrelevant builds, and your disks are full. Luckily, you’ve come to the right place for advice. Here’s how to set up automatic cleanup.

In many security and safety critical environments there can be requirements for long-term reproducibility of artifacts that are created. In this talk from NDC Tech Town, Mike Long shows how to use Docker to create binary reproducible applications from a C++ application.

Mike Long, CTO at Praqma, ran a Continuous Delivery Assessment at Bankwest in Australia in the summer 2018. Here is the testimonial from the CTO of Bankwest, Sean Langton.

In distributed architectures networking is usually taken as a given. However, when it does not function as we expect it is often hard to understand the reason. This blog post outlines some general insights into networking with more specific techniques for understanding the networking infrastructure of a Kubernetes cluster.

Choosing the perfect CI/CD tool for your project can be tricky. In this post we compare two managed CI/CD services - CircleCI and Google Cloud Build. Sami Alajrami is on hand to score our exciting CI/CD matchup.

Simply aligning your IT capability with your business goals isn’t enough to grow your company. To achieve real IT-enabled growth you’ll need to build on a foundation of technical excellence and thanks to DORA that’s something you can now actually measure.

Setting up an on-premise highly available Kubernetes cluster comes with many challenges. Rancher can help build a production grade cluster. Watch our Certified Kubernetes Administrator Henrik Hoegh set up a cluster and test the deployment.
