To address the issue of the ERP system Business Central where on-premises code needs to be cloud-optimized, it's essential to focus on streamlining the process for both customers and partners while also enhancing the overall system's efficiency and reducing costs associated with non-cloud-optimized code.

Despite the universal code name, GitHub counts 1.9k files with scope onprem in the base app repo. (https://github.com/search?q=repo%3Amicrosoft%2FBusinessCentralApps+scope+onprem&type=code)

Here are some ideas to improve this situation:

1. Code Refactoring and Modernization Initiative

• Audit and Refactor: Conduct a comprehensive audit of the existing Business Central base application code to identify areas that are not cloud-optimized. Prioritize refactoring this code to be cloud-friendly.
• Automated Tools: Develop or integrate automated tools to help identify non-cloud-optimized code and suggest or even implement optimizations. This can significantly reduce the manual effort required.

2. Incentive Program for Partners

• Incentivize Cloud Optimization: Create an incentive program for partners who contribute to cloud-optimizing the codebase. This could include financial rewards, certification benefits, or marketing support.
• Collaborative Platform: Establish a collaborative platform where partners can share best practices, tools, and code snippets for optimizing code for the cloud.

3. Enhanced Development Guidelines

• Cloud-First Development: Update development guidelines to enforce a "cloud-first" approach, ensuring that all new code is inherently cloud-optimized. I have a feeling that every partner is building their only local file access or printer agent base on https://github.com/microsoft/BCTech/tree/master/samples/BCAgent.
• Training and Resources: Provide extensive training and resources for developers on best practices for cloud optimization, including workshops, online courses, and documentation.

4. Gradual Deprecation of Non-Cloud-Optimized Code

• Deprecation Policy: Announce a clear timeline for deprecating non-cloud-optimized code within the base application. This gives customers and partners a clear horizon to plan for necessary changes.
• Migration Assistance: Offer migration assistance tools and services to help customers transition their custom code and configurations to be cloud-optimized.

5. Performance and Cost Analysis Tools

• Real-Time Analytics: Implement tools that provide real-time analytics on the performance and cost implications of running non-cloud-optimized code. This data can help customers understand the benefits of cloud optimization.
• Cost-Saving Reports: Generate regular reports for customers showing potential cost savings from cloud optimization, motivating them to make necessary changes.

6. Simplified Licensing Model

• Unified Licensing: Simplify the licensing model by merging the costs associated with cloud-optimized and non-cloud-optimized code. This can be done by offering a single, more straightforward licensing fee that incentivizes cloud optimization without penalizing users.
• Subscription Models: Introduce flexible subscription models that include both on-premises and cloud-optimized features, making it easier for customers to transition without immediate financial penalties.

7. Enhanced Support and Customer Communication

• Dedicated Support Channels: Establish dedicated support channels for cloud optimization issues, providing expert assistance to customers and partners facing challenges.
• Transparent Communication: Maintain transparent communication with customers about the benefits and necessity of cloud optimization, including regular updates on progress and available tools.

8. Legacy System Support

• Legacy Compatibility Layers: Develop compatibility layers that allow legacy, non-cloud-optimized code to run in a cloud environment with minimal performance penalties, buying time for full optimization.
• Phased Rollout: Implement a phased rollout strategy for cloud optimizations, allowing customers to gradually adapt their systems without abrupt changes.

By adopting these strategies, you can facilitate the transition to a fully cloud-optimized Business Central environment, reducing costs, improving performance, and enhancing the overall customer experience.
