The traditional model is a local installation (on-premises). In this case, we are talking about purchasing a perpetual license, which involves a one-time payment. Optionally, it is possible to pay the so-called BREP (annual maintenance fee). The advantages of such a solution include the control over the introduction of updates and upgrades. In addition, you have the possibility to use your own existing infrastructure and are less dependant on the Internet connection.
Dynamics 365 Business Central is a system that fully uses the capabilities of SaaS cloud applications. The advantages of this type of solution are primarily the lack of additional costs related to the maintenance of infrastructure and high reliability (99.9% SLA). In addition, the SaaS model provides easier access to other Microsoft cloud services and an exceptionally convenient process of performing updates.
When choosing a hybrid model, the system is installed on an external Data Center managed by EIP Dynamics or our partner. The advantages of such a solution include control over the introduction of updates. Another advantage in favor of the hybrid model is the fact that in case of a public cloud, there is no direct access to the database.
