Goal structure
The goal structure entails transitioning the ten million gadgets to connect with AWS IoT Core through Amazon Route 53 (or any DNS server). The backend companies, API gateway, and consuming purposes stay the identical.
Determine 3: Goal structure
Migration technique
The thought is to construct the migration technique based mostly on 5 key pillars designed to make sure a seamless transition. The method begins with sustaining a risk-free method by way of cautious planning and testing, whereas protecting operations managed with thorough documentation and monitoring. The technique emphasizes sustaining a minimal error floor by way of exact execution and validation steps.
Aligned with these technique rules, we suggest a phased method. Every part has particular targets and dependencies, permitting you to rigorously monitor progress and regulate your method as wanted.
Let’s discover every part intimately, highlighting the rationale behind the alternatives and offering a real-world instance.
Part 0: Preparation
The preparation part units the groundwork for a profitable migration. Throughout this vital stage, we concentrate on establishing a bridge between current infrastructure and AWS IoT Core, guaranteeing uninterrupted operations all through the migration course of.
On the coronary heart of this part is the implementation of a republish layer. This important part acts as an middleman, facilitating bidirectional communication between your self-managed dealer and AWS IoT Core. Consider it as constructing a safe tunnel that enables messages to movement seamlessly between each techniques.
Determine 4: Structure of the Preparation Part
The republish layer consists of two main elements:
- Gadget to backend (DTB): This part captures messages from gadgets related to your self-managed dealer and forwards them to AWS IoT Core. By implementing this path first, we will start migrating backend companies whereas gadgets keep related to the self-managed dealer.
- Backend to gadget (BTD): Working in parallel, this part ensures that messages from newly migrated backend companies attain gadgets nonetheless related to the self-managed dealer. This bidirectional functionality maintains system integrity all through the migration course of.
For optimum efficiency, we suggest implementing the republish layer utilizing container companies, resembling Amazon Elastic Container Service (ECS), or different compute choices based mostly in your particular wants. The code for these elements is easy: subscribing to a subject on a dealer and publishing it to the opposite dealer. The container service deployment permits the scaling up and down of situations to accommodate the necessities of the migration.
Part 1: Backend migration
This part focuses on migrating backend companies from the self-managed dealer to AWS IoT Core. Let’s perceive how we leverage the republishing layer emigrate the backends step-by-step with out dropping any messages.
Gadget to backend republishing layer
Throughout backend migration, sustaining constant message distribution by way of shared subscriptions is vital to not overload any of the prevailing or new subscribers. The republishing layer integrates seamlessly with current situations utilizing the identical shared subscription sample, guaranteeing balanced message consumption. As messages movement by way of this layer to AWS IoT Core and migrated backend situations, we rigorously management the introduction of every part to stop system overload. This measured method permits gradual migration whereas preserving the unique message distribution patterns and system stability.
Backend to gadget republishing layer
The Backend to gadget (BTD) Republishing layer is ready and configured on the Amazon ECS cluster stage, establishing connections to AWS IoT Core for message consumption. Not like the Gadget to Backend layer, all BTD republishing situations could be deployed concurrently since every occasion handles distinct gadget subjects, eliminating the chance of system overload. This permits quicker backend migration whereas sustaining dependable message supply to gadgets.

Throughout backend migration, establishing an AWS IoT Core rule to persist messages to Amazon Easy Storage Service (S3) serves as an important security web. This message backup permits restoration and reprocessing if surprising points happen through the transition, guaranteeing no gadget messages are misplaced.
With the republishing layer in place and totally examined, the migration course of follows a scientific sample:
- Introduce the primary DTB republishing occasion
- Confirm message movement by way of this occasion to AWS IoT Core and again to gadgets
- Take away the corresponding unmigrated backend occasion
- Progress incrementally by way of all backend situations
This methodical method facilitates a clean transition of all backend companies to AWS IoT Core. The identical technique extends to different platform companies, sustaining operational continuity all through the method.

Part 2: Gadget migration
This part requires explicit consideration to element, because it immediately impacts end-user expertise and gadget connectivity.
The important thing to a profitable gadget migration lies in implementing a weighted DNS routing technique (or any routing technique of your selection), with a service like Amazon Route 53 (or any DNS server of your selection). This method permits for granular management over the transition:
- Start with a small proportion (sometimes 1-2%) of site visitors routed to AWS IoT Core.
- Monitor gadget connections, message supply, potential throttling limits exceeded, and error charges counting on AWS IoT metrics and dimensions in Amazon CloudWatch.
- Progressively improve the share based mostly on efficiency metrics.
- Keep the flexibility to rapidly revert site visitors if wanted.
Throughout this part, we leverage AWS IoT Core’s just-in-time registration capabilities to robotically provision assets for connecting gadgets. This automation considerably reduces the operational overhead of managing large-scale migrations.
Determine 7: Structure visualizing the Gadget Migration
After finishing gadget migration, the republishing layer stays lively, persevering with to ahead messages to the self-managed dealer. This design gives a vital rollback path – ought to any points come up, site visitors could be instantly reverted to the self-managed dealer whereas sustaining full message supply between gadgets and backend companies.
Part 3: Cleanup
The cleanup part marks the ultimate step within the migration journey. The republishing layer naturally phases out first, making a clear isolation of the self-managed dealer. As soon as monitoring techniques and dependent processes verify zero site visitors to the self-managed dealer, and all techniques function easily by way of AWS IoT Core, the dealer’s decommissioning completes the migration.
Determine 8: Structure visualizing the completed migration matching the goal structure
This measured sequence ensures a sleek transition whereas sustaining system stability all through the ultimate migration part.
