Dynamics 365 Network Requirements
Bandwidth Planning
The requirement for bandwidth is based on the number of users and data transactions. A rule of thumb is to provide bandwidth of at least 50-100 kbps based on the number of active users per session for cloud deployments.
Latency and Reliability
The latency between the client and the Dynamics 365 Server should be under 150 ms for complete user satisfaction. The reliability of the network is also critical. Packet loss or high latency will degrade the loading speeds of forms and the responsiveness of APIs.
Ports and Firewall Rules
Make sure ports 80/443 for HTTP/HTTPS, and any SQL connections are open as standard practice. For on-premise, internal firewalls and reverse proxies should be configured for traffic from client machines to application servers to database servers.
TL;DR: Maintain network latency below 150 ms, bandwidth of 50–100 kbps per active user, and open ports 80/443 for HTTP/HTTPS to ensure fast and secure Dynamics 365 performance.
Dynamics 365 Core Infrastructure Requirements: Cloud vs On-Premises Setup
On-Premise Infrastructure
It requires hardware or virtualized hardware, SQL databases, Active Directory, and storage management. IT teams prepare the environment themselves, patch it internally, and scale the service as directed.
Cloud Infrastructure
This option is hosted within Microsoft Azure and allows for managed scalability, automatic patches, and global access. Azure handles uptime, security patches, and disaster recovery, thereby greatly lowering infrastructure overhead.
Key Differences: On-Premise vs Cloud
In an on-premise model, the business manages and updates its servers on its own while overseeing security, which provides the most significant amount of control but potentially increases the maintenance and costs. The cloud model is managed by Microsoft, allowing for auto-updates, a lower cost of overhead, and more effortless scalability, which is ideal for the organization that prioritizes flexibility and reduces the burden on IT.
TL;DR: To run Dynamics 365 effectively, you’ll need a Windows Server OS, a supported SQL Server and .NET framework, and a stable network connection. Users can access Dynamics 365 through modern browsers such as Edge, Chrome, or Safari.
Dynamics 365 Hosting Options
Self-Hosting (On-Premise or Private Cloud)
