With the ground breaking revolutionary fully managed functional programming support by AWS; can AWS lambda speak to external internet / systems for external communication.

Lambda places some restrictions on network capabilities:
Inbound network connections are managed by AWS Lambda, only TCP/IP sockets are supported, and ptrace (debugging) system calls are restricted.
