Cloud vs. Self-Serve
The Cloud Service from Marketcircle was launched in 2014 as a test, and subsequently made a public service in 2015. Your data is hosted by Marketcircle, in a secure facility. The data between your personal devices and the Cloud is transacted using some of the strongest encryption methods. The backups, location, and backend tech support are all handled by Marketcircle. Cloud is a subscription on a per user basis.
The Self-Serve option is what Marketcircle first offered for Daylite, and is possibly the majority of user setups today. Unlike Marketcircle Cloud, one would need a computer to host Daylite, and network adjustments for external sync services. Backups would also need to be managed.
Self-Serve costs $299 per user.
The cloud option is cost effective for small user base installations of 1-3 users. Larger user groups will find that self-serve is a much better option, even though backups & infrastructure would need to managed. Primary reason for this would be cost.
Lets take an example of a 5 user group over 36 months. For a new setup, the license would cost $1500. Hardware and setup costs could run between $1500 - $2500. Since the license is perpetual, there are no additional expenses, except perhaps tech support for your hardware etc. So the over all cost would between $3000 - $4000. per user/month could be between $16-$22/month/user. The cloud option would cost $24 - $29/month/user for a cost of $4320 - $5220, depending on payment plan.
Which solution is best for you, depends on your specific requirements. One can always move to cloud, however it is not possible to move back to self-serve.
