Cooperative update
Cristiano Giuffrida, Andrew S. Tanenbaum · 2009
Many real-world systems require continuous operation. Downtime is ill-affordable and scheduling maintenance for regular software updates is a tremendous challenge for system administrators. For this reason, live update is a potential solution as it allows running software to be replaced by a newer version without stopping the system. The vast majority of live update approaches proposed as a solution to this problem aims to support existing software systems, while striving to maintain a good level of safety and flexibility.
