Komm.ONE decided to create a complete new `Cloud-Platform Infrastructure`. The project started several years ago and replaced all software and hardware. Now it was our turn - So we started planning and implementing our test stage in the new environment. 2023 will challenge us to review and adapt the automation stack to changing requirements...

|
|
|
|
|
|
In 2021 I wanted to get back into coding and software architecture. So I started refactoring our Self Service Portal. The requirements have changed so much in the meantime that we decided to start from scratch. So we started a new full stack project containing these key elements:

The year 2020 started with designing a new Automation Stack. My main goal war to upgrade the tech stack while

|
|

|
|

keeping the required operating an maintenance as low as possible. So I replaced some products to split the features / responsibilities:
