Why did we build ?
Because cloud native delivery and operations is a BIG challenge!

Quote: “Pipelines seem to be becoming our new future un-managable legacy code!“
First: solves the Continuous Delivery Problem!

10. Second: Continuous Delivery is NOT ENOUGH!

11. Continuous Delivery – Launch control
Launch operations are supervised and
controlled from several control rooms (also
known as a firing room). The controllers are
in control of pre-launch checks, the booster
and spacecraft. Once the rocket has cleared
the launch tower (usually within the first
10–15 seconds), is when control is switched
over to the Mission Control Center

12. Continuous Operations – Mission Control
A mission control center (MCC, sometimes
called a flight control center or operations
center) is a facility that manages space flights,
usually from the point of launch until landing
or the end of the mission. It is part of
the ground segment of spacecraft operations.
A staff of flight controllers and other support
personnel monitor all aspects of the mission
using telemetry, and send commands to the
vehicle using ground stations
