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.

● Btrfs with snapshots and rollback for transactional updates
● Read-only filesystem with overlayfs for /etc
●
Cloud-init for configuration
● Kubernetes master with dashboard to manage cluster
● Etcd
● Saltstack
● Installer or ready to use images (Cloud / Virtualization)

Definition
A “transactional update” is a kind of update that:
● 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
9
Update
● Transactional Updates
● Automatic updates
● Can be disabled
● Maintenance Window
● Policy defined updates
● Standard RPM with zypper, snapper and btrfs progs
● SMT as local proxy
