What's the Big Deal with JAMStack?
What is JAMstack?
Why should you care?
There are major of benefits for you, as a potential client engaging a developer to build a site, to using JAMStack.
JAMStack does not rely on databases like Wordpress, Joomla, Drupal, and other traditional CMS platforms. The content is prebuilt and ready to rock when a web browser requests a page. That will, in hand, increase the speed of your site because the pages do not need to be assembled.
No databases, no servers... means nothing to break into. It's like eliminating bank robbers by eliminating banks. The need to continually upgrade and patch CMS systems and the databases they rely on is the the LARGEST attack vector a website can have... and all that goes away.
Since there are no server-side parts, there's less of a need to keep costly IT staff around to keep things up and running... thus reducing your overall cost significantly.
