Go with what works best for your organisation. You can choose how you want Microsoft Dynamics 365 Business Central deployed - true Cloud, hosted, or on-premise - to suit your company's requirements.
Business Central is designed for the Cloud, so you enjoy lower upfront costs and having infrastructure maintained for you, by Microsoft. But if you'd rather host your ERP on your own infrastructure, Business Central can be deployed on-premise or as a hosted system — and the user experience is the same.
Microsoft Dynamics Business Central runs where you need it, in the cloud or on-premises, with the same user experience no matter how you deploy.
Business Central's mobile app supports cloud and on-premise users with a modern, consistent experience across Windows, Android, or IOS devices.
