Can I pause my free tier service on AWS and resume it whenever is required?

I've been using AWS free tier service for hosting my blogging site. For some reasons, I didn't get time to post some articles or blogs on my site and my site is almost as it is as I hosted it. And I am paying each month $0.5 as AWS Bill.

I just wanna know that is it possible to stop my free tier service for now and can continue this service afterward when I'll be in need of hosting it again. And if it is possible How can i do that?
