There is a lot of confusion around the naming of Microsoft Dynamics 365 products so I wanted to create a post for reference.
Each Dynamics solution meets a different business need and utilizes a completely separate programming language and integration model so in most cases developers will not go across multiple Dynamics offerings.
| On-Premise Solution Name | Cloud Solution Name | Other Names | Sub-Products | Programming Language |
| Dynamics CRM | Dynamics 365 | D365 Customer Engagement (D365CE) | D365 Sales, D365 Customer Service, D365 Marketing, D365 Field Service, D365 Project Service Automation | .NET |
| Dynamics AX | Dynamics 365 for Finance & Operations | D365FO, D365 FinOps | D365 Finance, D356 Supply Chain Management, D365 Commerce, D365 Human Resources | X++/.NET |
| Dynamics NAV | Dynamics 365 Business Central | D365BC | - | AL |
| Dynamics GP | Dynamics 365 Business Central | D365BC | - | AL |
| Dynamics SL | - | - | - | - |
