One NoSQL customer switched from Open Source to a commercial solution because their original configuration on open source used almost 200 servers. Switching to the commercial solution allowed them to use fewer than 20 servers, which saved them costs in hardware, data center and administration (server and DBA).
It is easy to get caught up in the “we’re only using Open Source for everything” approach. If you can do this successfully, that is terrific! But if it means that instead of focusing on your business application, you are also having to integrate all the pieces together and incorporate this into your application, this may not be the best solution for the long term.
There are many types of applications that NoSQL can solve, ranging from small and simple to very large and complex, and anywhere in between. You need to make sure you do your due diligence in evaluating the completeness of the solution and avoid getting caught up in the industry hype.
Embrace the change that NoSQL provides and realize the possibilities!
