Software systems, especially at scale, cannot afford rollbacks or cut-overs and must always move forward due to the permanent nature of data. Data, once saved, must be managed forever, requiring updates to be additive and systems to be distributed. Challenges arise as different parts of the system need to operate on shared definitions of business logic, leading to complexities during updates. Key strategies include making additive changes, being permissive about inputs, and managing updates to both databases and code to ensure systems remain in sync.
