My company is currently evaluating different PaaS and SaaS options for a new development platform. If you are able to point out cost comparison evaluations for different PaaS platforms I would be very interested to check them out.
We are currently shortlisting products. Our current platform is SugarCRM community edition which we deliver as a cloud service via Amazon AWS. It imposed many limitations on our product and we investigate two options, a replacement CRM of more current codebase or a PaaS/SaaS platform that will allow us to focus on development of new product with less effort managing version control and deployments.
Since our skill set is in PHP and JS we look at platforms that provide that layer of coding, Yii, Heroku, Cloudbees Jenkins and more. Due to our NGO target market the operating cost is a major consideration which is why we ruled out Salesforce for instance.
I'm interested in a cost comparison model for fixed scope project with x number of developers. If you have any information that you think may be valuable please let me know.
