There is only one apparently abstract upside of using Lightsail, simplicity, or significantly simplified interface.
Also, the first page of Lightsail talks about lower charges. My question is how is it considered to reduce charges compared to EC2? Consider $5 Lightsail plan which charges $0.0067/hour of an instance (which is the cheapest) where EC2's same type of instance (t2.nano) costs just $0.0059/hour.
What am I missing? A detailed price comparison would be much appreciated showing how Lightsail costs lower as advertised.
