Also referred to as a bundle, a Lightsail plan includes a virtual server with a fixed amount of memory (RAM) and compute (vCPUs), SSD-based storage (disks), and a free data transfer allowance. Lightsail plans also offer static IP addresses (5 per account) and DNS management (3 domain zones per account). Lightsail plans are charged on an hourly, on-demand basis, so you only pay for a plan when you’re using it.
AWS designed the Lightsail service to make it simpler to understand and purchase rudimentary compute capacity. AWS also manages the infrastructure, which shares the same uptime and global regions and availability zones as EC2, and makes it available with a few mouse clicks.
