With that one exception, deployment-level components are the same as monoliths. The functions generally all exist in the same processor and address space. The strategies for segregating the components and managing their dependencies are the same.2 As with monoliths, communications across deployment component boundaries are just function calls and, therefore, are very inexpensive. There may be a one-time hit for dynamic linking or runtime loading, but communications across these boundaries can still be very chatty.
