Now benifit of this is our front facing is totally based on functions and probability of its going down is very less. Our backend on the other hand requires monitoring facilities and usage to track down it's uptime and automated heaing.

The Front end

Our Front end is Using React with Gatsby and Netlify Functions. The Reason for Using Gatsby is it's Performance , SEO and Automated Splitting is built into framework which makes it perfect for Creating High Performant Pages.

The back End
