Our Goal
A container infrastructure platform is software
that allows customers to provision, manage,
and scale container-based applications.
We deliver a container application development
and hosting platform that automates the tedious
management tasks allowing customers to focus
on development and writing apps to meet
business goals.

Definition

● Is atomic
● The update does not influence your running system
● Can be rolled back
● If the upgrade fails or if the update is not compatible, you can quickly restore
the situation as it was before the upgrade
