This approach puts some limitations on packing efficiency, and also necessitates a container trade-off between security and code compatibility based on the types of syscalls containers are allowed to make. Approaches such as unikernels can help with this, but once again the AWS requirement to be able to run unmodified code rules these out.

Traditionally one of the major costs when moving data in and out of memory (be it to persistent media or over the network) is serialisation.
