I would like to use AWS and especially Amazon Simple Email Service (SES) in order to setup a webservice allowing to send emails.
Emails would be triggered by some kind of POST request to the webservice with some authentication, and the webservice would then just send the email on behalf of the web service user.
Where should I start? The webservice part looks dead simple but I’m not familiar at all with web services. I still need to run some kind of multithreaded webserver since there could be a bunch of concurrent requests.
Is there a way for me to write a very simple web server in Ruby or Java to do that? Any pointer appreciated.
After some digging, the simplest solution is to use something like node.js or sinatra. The nice thing is that these are almost self-contained and require barely any configuration. They provide a very easy way to reply to HTTP requests.
Once you get one of these, you start the script with a port.
The small webservice will now listen on that port. You only need to take action based on the requests passed as parameter.
And yeah, now it sounds so obvious…
