Sustainable Open Source

Open-source software today and tomorrow

The color green and open source—not an obvious match, at first glance. Really not? Wrong! Open source actually is green. Would you like to know in what way this is the case and what everything has to do with ATIX's green rhino and Istio? Then enjoy reading my blog!
KEDA blog

Scaling Applications to Zero with Kubernetes and KEDA

For cost reasons, it is often neither feasible nor desirable to assign enough resources to a deployment for it to be able to handle peak loads at all times. Therefore, we typically scale applications up and down based on the load they are currently facing. This usually involves a minimum number of instances deployed at any time, even if there is no load. This minimum can force us to keep more worker nodes in our Kubernetes cluster than necessary as the instances have an assigned resource budget. In this blog post, we will take a look at how to reduce the minimum amount of deployed instances to zero and discuss which kinds of applications benefit from that the most.
Kafka and Ansible

Automating Kafka with Ansible

In all areas of life, there are a lot of issues we are not aware of. To measure these problems, we use the so-called fulfillment rate. For example: with a fulfillment rate of 90%, a heart beat would stop every 85 seconds, and an average A4 page of text would contain 30 typos. A fulfillment rate of 99.9% (which seems a lot) still means 22,000 wrong bank bookings per hour, and a total of 32,000 missed heart beats per year. The answer is automation and standardization! These approaches help solve problems we are often not aware of.

Experiences of ATIX apprentices

In the last 12 months, two of our colleagues successfully completed their apprenticeship at ATIX. We are pleased that they decided to continue working as part of our team – we look forward to the future collaboration, Anh and Emiri!
Kubernetes kOps

Kubernetes kOps

The cloud and Kubernetes belong together, right? More or less, this is the case. Although containerized applications quickly find a home environment with cloud providers, for some myterious reasons, it’s not that easy to set up a Kubernetes environment in the cloud. Unless you use kOps, the tool written exactly for this purpose. This is how it works.
Configuration Management across Different Networks with AWX ATIX blog

Configuration Management across Different Networks with AWX

At the Chemnitz Linux Days 2023, Ottavia Balducci, IT Consultant at ATIX, presented the advantages of AWX. AWX is a tool that can be used to configure hosts with Ansible. It is therefore particularly popular with larger organizations. AWX is open source, fully customisable, has a web UI, REST API, RBAC, CI/CD ... There are many reasons for working with AWX.

Configuring Hosts using Ansible

You can use Ansible to configure managed hosts within orcharhino. For our up-to-date documentation, see Configuring Hosts using Ansible. Ansible is an automation engine and configuration management tool. It works without client and daemon and solely relies on Python and SSH. Ansible consists of a control node, for example a notebook, a workstation, or a server and managed nodes, that is the hosts in its inventory. You can use Ansible to configure hosts similar to Puppet and Salt.

Registers and Macros in Vim

Chemnitz Linux Days 2023—and ATIX in the thick of things! In his talk, our Senior IT Consultant Jan Bundesmann presented registers and macros in Vim.

New Adventures in ArgoCD: Automating Automation

ArgoCD is a great CICD tool for facilitating Git-based Kubernetes deployments. Helm is a widely used solution, with good reason, to simplify complex Kubernetes deployments and customize them to your needs. It's even supported by Argo per se. You can't ask for anything better than a combination of the two. Or can you?
