Can I keep my AWS IoT MQTT clients?

You can often reuse standard MQTT clients after updating the endpoint, TLS trust, and authentication. Test client IDs, topics, delivery, and reconnects; AWS-specific SDK features may need changes.

What needs to change beyond the broker endpoint?

Map certificates and topic policies, recreate message routes, and replace AWS services such as Device Shadows, Jobs, and provisioning where needed. Certificates from your own CA may be reusable after configuring trust; AWS-issued certificates need a separate migration plan.

Will moving to EMQX lower my costs?

EMQX can cut AWS IoT Core costs by up to 80% for workloads with high message rates. Savings vary by workload and deployment.

Can I run EMQX outside AWS?

Yes. Use managed EMQX Cloud in a supported cloud and region, or run EMQX Enterprise in your own cloud or data center.

Can I migrate from AWS IoT Core in stages?

Yes. Validate authentication, message delivery, and downstream data flows with a small group of devices. Then migrate in batches, with a tested rollback plan and temporary overlap between platforms.

Why switch

Why move from AWS IoT Core to EMQX?

Build around your MQTT workload, with more choice in deployment, data flows, and operations.

Save up to 80%

Explore savings on high-volume MQTT workloads. Compare EMQX capacity and traffic costs against your current AWS IoT Core bill.

Full MQTT 5.0 support

Build with shared subscriptions, session expiry, and QoS 2 for greater control over message delivery.

Flexible scaling

Choose the connections and throughput your workload needs, then expand capacity as you grow.

Multi-cloud freedom

Run EMQX on AWS, across clouds, or on premises. Choose managed or self-managed deployment to fit your team.

The difference

Escape the hidden costs of AWS IoT Core pricing

Tired of navigating a maze of unpredictable fees and architectural constraints? See why enterprises are switching to EMQX for transparency and control.

With AWS IoT Core	With EMQX
Complex & unpredictable pricing AWS IoT Core meters connectivity, messaging, rules, and other features separately. Your total also depends on the AWS services used downstream.	Transparent & predictable plans Compare the EMQX plan or license, infrastructure, network traffic, and operating effort against the same AWS workload.
Strategic vendor lock-in Device Shadows, Jobs, provisioning, and IAM-based integrations can be part of your application architecture.	Bring your own cloud (BYOC) Move MQTT messaging first where practical. Retain, replace, or rebuild each AWS-specific service your applications depend on.
Service quotas and throttling AWS IoT Core applies account and connection quotas. Check which limits can be increased and how they affect your peak workload.	Capacity and configuration control Choose an EMQX deployment sized for your load. Validate resource limits, throughput, and recovery as traffic grows.
MQTT with documented differences AWS IoT Core supports MQTT 3.1.1 and 5.0, including shared subscriptions, with documented differences from the specifications.	100% MQTT 5.0 compliant Use EMQX MQTT 3.1, 3.1.1, or 5.0 with configurable topics and delivery settings, including QoS 0, 1, and 2.

This historical model is not a current price quote or a total-cost estimate. It uses 730 hours per month and simplified billing formulas; it does not model payload size, region, all service features, network traffic, or operating costs. Positive differences indicate savings; negative values indicate higher modeled EMQX costs. Validate your workload against current pricing.
