What services are active on account?

I am assuming you would like to find out what services e.g. Apache, IIS is running on Linux/Windows Lightsail server. You can SSH or RDP to the server to find out.

===Extracted from Lightsail FAQ (https://aws.amazon.com/lightsail/faq/ )=== Lightsail offers a 1-click secure connection to your instance's terminal right from your browser, supporting SSH access for Linux/Unix-based instances and RDP access for Windows-based instances. To use 1-click connections, launch your instance management screens, click Connect using SSH or Connect using RDP, and a new browser window opens and automatically connects to your instance.
