Nice article, thanks for sharing!
Wow! appreciate the depth of knowledge and clarity you covered. Keep up the great work!
Thanks for the article and sharing the info but I like to add some since I do not fully agree with your :)
Saas does not cover the hosting of your actuall site. You need to managed that your self trough a hosting provider, like vercel azure amazon or any static site provider. Therefore you need to add that on top of your prize for Saas as well as the a lot of the other costs for support security and so on.
Since Saas is a headless aproach for builing websites you still need to build the site. It is not a Wix soulution yet at least. :)
When it comes to scaling Paas does require some help from client/partner but at the same time it does scale automaticlly as well. The DevOps CI/CD is also something that is handled by optimizely in both scenarios since we still need to have that for our sites in Vercel or in Optimizely Paas it is similar.
Thanks Sunil, Khushant Dhingra for your valuable feedback.
and, thanks Eric for adding more insights on this.
Not a big fan of Optimizely SaSS as it is still in evolution phase and so many things changing quickly. On the top of this, in any PaaS system you have flexibility to add plugins of your choice and control overhead. Here with SaaS, it is always a new request to support for adding plugins and therefore, it is an extra cost (ofcourse depends on type).
By the way good write up Praful.
Thanks Manoj Kumawat,
you are right, not only cost and but the thing is that the time matters more I would say, which is more concerning.
