Safety by Design
A bulkhead is a structure that isolates damage to one area. It is a common technique for designing safe and resilient systems, vehicles, equipment and services.
CodeA bulkhead is a software design technique that divides code into independently deployable units such as microservices. For example, the sections of a website can be implemented as separately deployed cloud services. When one page goes down, the rest of the site stays up.
ShipsA bulkhead is a vertical wall in the hull of ships. They originated in the 15th century as a way to keep cargo from shifting in heavy seas. All walls in a modern ships are known as bulkheads. They serve functions such as structural support and dividing space into rooms. Some bulkheads are designed to be watertight and fireproof to isolate damage to one section of ship.
AircraftPressure bulkheads seal the cabin of aircraft for high altitude flight.
