Since your application seems to do video streaming, it seems to me that you would need a reasonable specification.

Also, you may need to consider scalability, etc., so EC2 is probably a better choice.
However, we do not know the specific performance requirements of your application, so please consider verifying this if necessary.

I understand that you are trying to configure the most efficient architecture for your dynamic web application. I have suggested a solution based on the information you have provided; however, please research the benefits and use-cases for EC2 and Lightsail outside of this response. EC2 best fits the requirements listed above for the following reasons:

• Video streaming may require more computationally intensive loads than what Lightsail has to offer
• EC2 has many options for compute optimization that are not possible in Lightsail
• EC2 offers pay-as-you-go pricing which provides a balance between performance and cost optimization
