Options for running Server Side/Web Applications/Web API on AWS

Virtual Machines => EC2 (Elastic Compute Cloud)
- Launch EC2 instance
- Install the technical stack (python, java, .net etc)
- Install the necessary libraries
- Run the application
- Manage the OS updates & technical stack updates
- Manage the application versions
- Manage the scaling
- pricing is usually done per hour but can be done in seconds, but to make our application work we need to run this all the time
Elastic Beanstalk
- Launch an environment with pre-installed tech stack (python, java, ruby, .net etc)
- Deploy your application version
- AWS will manage
  - OS updates & technical stack updates
  - Scaling
- pricing is usually done per hour but can be done in seconds, but to make our application work we need to run this all the time
Serverless Computing using AWS Lambda
- Write the code and deploy the code (rest is AWS doing the stuff)
- you will be charged per millisecond when your code is executed.

I have an application which is support page for the company where user creates support tickets
- How many users are logged in to your application in the last few months (need hourly stats)?
- If the users that are logged are always greater than 10-100 at any point of time choose => Elastic BeanStalk or EC2
- If the users that are logged in are less that 10-100 at any given point and we have many cases where the number of users is zero in a month go with lambda
On my website i would like to randomly take surveys from some users. What do you prefer for running surveys
Create a AWS lambda function for survey and expose it on your application.
