Cloud vs. On-Premises: Choosing the Right Fit for Your Dynamics 365 Implementation

For IT Directors in manufacturing, the decision between cloud and on-premises deployments for Microsoft Dynamics 365 can significantly impact operational efficiency, cost, and scalability. Here’s a detailed breakdown to guide your decision-making process:

System Setup

• Cloud: Hosted by Microsoft, deployment is straightforward, with a typical setup time of 1–2 weeks. This is ideal for businesses looking for a quick time-to-value. Power BI integration leverages cloud-based D365 data seamlessly, allowing for real-time insights and advanced analytics without additional infrastructure.
• On-Premises:Requires hosting on private servers or rented VMs, taking 1–2 months due to the need for acquiring and configuring necessary hardware and licenses. Power BI integration often necessitates costly on-premises solutions or reliance on Power BI Data Gateway, adding complexity to analytics and reporting processes.

Features

Licensing:

• Cloud: A simple subscription-based model where you only need D365 licenses and optional Power BI licenses, reducing upfront costs and complexity.
• On-Premises: Additional licenses for Microsoft SQL Server and Windows Server are required, increasing costs and setup effort.

Customization & Development:

• Cloud: All customizations and updates are included in the subscription, streamlining ongoing development and minimizing unexpected expenses.
• On-Premises: Customizations may require purchasing additional objects, particularly for Business Central, and often demand more manual effort and costs.

Power Apps & Office 365 Integration:

• Cloud: Power Apps installation is available, making it easier to create custom solutions. Office 365 integration works seamlessly, requiring minimal setup and ensuring smooth communication between tools.
• On-Premises: Power Apps is not available, and Office 365 integration often requires extra configuration, such as Azure Active Directory setup, with some integration limitations.

Sandbox Environments:

• Cloud: Offers up to three environments automatically set up via the admin center, allowing businesses to test and develop in isolated spaces.
• On-Premises: Unlimited environments can be created, but they require manual setup, which could mean additional time and resources.

Local App Integrations:

• Cloud: Requires communication through the internet, which may introduce risks or complexities, particularly with local systems.
• On-Premises: Direct integration with local apps is simpler, given that it operates within the local network, reducing potential security concerns.

Maintenance

System Updates:

• Cloud: Updates are mandatory and automatically applied (1–2 months for Business Central, up to 6 months for Finance), ensuring your system stays secure and up-to-date without manual intervention.
• On-Premises: Updates must be applied manually through a Microsoft partner, requiring coordination and potentially delaying access to new features.

Recovery & Backups:

• Cloud: Backups and disaster recovery (DR) are managed entirely by Microsoft and included in the subscription, offering peace of mind with minimal IT involvement.
• On-Premises: The IT team must handle backups and create a robust disaster recovery plan, which can be time-intensive and costly to maintain.

System Monitoring:

• Cloud: Microsoft takes full responsibility for monitoring hardware, software, and availability, ensuring uptime and reducing the burden on your team.
• On-Premises: Monitoring requires dedicated IT resources to oversee and manage infrastructure, increasing operational overhead.
