Our company builds micro saas applications. Based on the application we decide whether to deploy it over one of our shared servers or on a dedicated server.

We decided to Lightsail over EC2.

1. Lightsail is a lightweight, simplified product offering that has a dramatically simplified console. The instances run in a special VPC, but this aspect is also provisioned automatically, and invisible in the console.

2. Lightsail supports optionally peering this hidden VPC with your default VPC in the same AWS region, allowing Lightsail instances to access services like EC2 and RDS in the default VPC within the same AWS account.

3. Bandwidth is unlimited, but of course free bandwidth is not -- however, Lightsail instances do include a significant monthly bandwidth allowance before any bandwidth-related charges apply.

4. It has predictable pricing with no surprises at the end.

5. The flexibility of EC2 leads inevitably to complexity. Whereas for Lighsail there is virtually no learning curve, here. You don't even technically need to know how to use SSH with a private key -- the Lightsail console even has a built-in SSH client -- but there is no requirement that you use it. You can access these instances normally, with a standard SSH client.
