There is not one clear cut answer on this. It depends on what your company values, i.e. cost vs. agility. If you are using the cloud for what it was meant for availability, scalability, elasticity--and those are the things that your org values--its the right fit for you. If on the other hand you value cost then it clearly isn't the right fit.

The true value of the cloud is when can architect your solution to utilize the various services the cloud providers offer, RDS/DynamoDB, CDN, Lambda, API Gateway, etc. so that you can scale quickly when you need to.
