Platform as a Service (PaaS) definitely provides great benefits when it comes to rapid development and deployment capabilities. However, from an (product) architect’s point of view PaaS is more of a blackbox that can be used (only) in a certain prescribed way.

If you are the CTO of a product company and you have answered “Yes” for the following requirement

• You want to have control over the db design and the data architecture
• You want to design the layers of your architecture
• You want to use a different security framework (than the one provided by your PaaS provider)
• You want to switch to a different cloud provider for economic reasons
• You want to deploy your product as on-premise for large customers
• You want to include a particular third party UI control in your page to offer better usability.

then PaaS is not for you.

Now you ask yourself what is the right fit for your business?
