Also, I personally believe, long term, higher level declarative languages will have a better fit with the cloud as they will be more portable than lower level languages that assume a specific runtime.
这些语言提供了高性能，但是存在可移植性和可靠性等问题。
These languages offer high performance, but they suffer in terms of reliability and portability.
