What is the point ?
Unless you have a very intermittent large demand - why use a cloud service?
For any reasonably predictable demand on-site equipment is almost certain to be cheaper (except for web hosting if you have a poor internet connection).
(Taking the pricing given by Platypus in his Yawn comment above - 2 cores 2GB RAM and 40GB SSD works out to $240/year - a new 4 core 4GB RAM 128GB SSD Lenovo B50-10 Laptop can be purchased for £280 on ebay - in less than 2 years this system will cost less that the lightsail setup while being twice as powerful as the lightsail setup. )
Also using an onsite server means that your data is not exposed to the NSA and whichever US companies they feel like selling it to.
