CRM Online is a cloud-based offering of Microsoft Dynamics CRM where
all the backend processes (such as application servers, setups,
deployments, databases, licensing, etc.) are managed on Microsoft
servers. CRM Online is a subscription-based offering which is preferred
for organizations who may not want to manage all the technicalities
involved in a CRM implementation. You can get started with setting up
your system in a few days (not weeks, months or years) and access it on
web via your browser.
