Re-engineering Legacy IoT platforms to cloud based platforms: Part 2

Step 1: Assess the existing architecture and data The first step in re-engineering a legacy IoT platform is to assess the existing architecture and data. This involves identifying the components and functionality of the legacy platform, as well as any data dependencies and limitations. This step is critical in determining the feasibility of re-engineering and in determining the scope of the project.

Step 2: Define the target architecture and technology stack Based on the assessment of the existing architecture and data, the next step is to define the target architecture and technology stack for the re-engineered platform. This involves deciding on the cloud platform to use, the technology stack, and the microservices architecture. For this case, the organization has decided to use Azure as its cloud platform and to adopt a microservices architecture.

Step 3: Plan the migration Once the target architecture and technology stack have been defined, the next step is to plan the migration. This involves determining the steps and timelines for migrating the data, components, and functionality from the legacy platform to the new cloud-based platform. It’s important to carefully plan this step to ensure that the migration is smooth and that there is minimal downtime during the transition.

Step 4: Implement the new platform The next step is to implement the new cloud-based platform. This involves setting up the cloud infrastructure, deploying the microservices, and integrating the new platform with the existing systems and data sources. During this step, it’s important to thoroughly test the new platform to ensure that it meets the requirements and that there are no issues with data loss or system downtime.

Step 5: Synchronize data Once the new platform has been implemented, the next step is to synchronize the data. This involves ensuring that the data is in sync between the legacy platform and the new cloud-based platform, and that there are no discrepancies or data loss. To achieve this, organizations can use Azure’s built-in data synchronization features, such as Azure Cosmos DB, which provides globally distributed, multi-model databases with low latency and high throughput.

Step 6: Transition to the new platform The final step is to transition to the new cloud-based platform. This involves decommissioning the legacy platform and ensuring that all business-critical operations are fully supported by the new cloud-based platform. During this step, it’s important to closely monitor the performance of the new platform to ensure that it is functioning as expected and that there are no issues with data loss or system downtime.

In conclusion, re-engineering a legacy IoT platform to a cloud-based platform is a complex process that requires careful planning and execution. By following these steps and leveraging the power of Azure, organizations can successfully transition to a modern, cloud-based platform that provides greater scalability, reliability, and real-time data access.
