Shulou(Shulou.com)06/03 Report--

The domestic version of EMQ X Cloud, the world's first MQTT 5.0public cloud service, is officially launched, with a 7-day free trial for first-time registered users. Huawei Cloud and Aliyun are already supported, and other cloud service providers will be launched one after another.

EMQ X MQTT server has been selected by thousands of enterprise users around the world in the past few years, providing stable basic services for customers' Internet of things applications. EMQ X Cloud-MQTT public cloud services are based on some of the best practices summarized by our service customers to provide Internet of things MQTT 5.0services that are rapidly deployed, easily managed, resilient and deployed across multiple clouds. With the basic computing infrastructure provided by cloud service providers, EMQ X Cloud provides services to dozens of countries and regions around the world, providing low-cost, secure and reliable cloud services for 5G and IoE applications.

On EMQ X Cloud, users can create an EMQ X cluster with highly available and exclusive instances in just a few minutes, and start prototyping and application development immediately without paying attention to the follow-up operation and maintenance work. After the product is launched, the cluster can be expanded without downtime to cope with the capacity expansion brought about by business growth, ensuring availability and maximizing cost savings.

Unlike most other public IoT Hub cloud platforms, EMQ X Cloud provides a unique cluster of MQTT 5.0 servers in an isolated environment, which has significant cost advantages and fewer usage restrictions. EMQ X Cloud can still maintain a low cost in the case of a large number of messages. Through peer-to-peer network and other functions, we can realize the docking of big data analysis, message storage and other business systems deployed by users in the private network.

EMQ X Cloud supports the migration of existing Internet of things projects, is fully compatible with EMQ X Enterprise Edition, supports bidirectional migration to EMQ X Enterprise Edition, and can migrate bidirectionally with public cloud platform IoT Hub with a small amount of adaptation.

Product characteristics

MQTT cloud service provides secure and reliable two-way communication capabilities for applications and devices. It not only supports massive device connections in large clusters, but also provides other value-added capabilities, such as device management, rule engine, data persistence and Kafka data bridging, covering all kinds of IoT application scenarios.

The key features of EMQ X Cloud are as follows:

Full support for the protocol

MQTT Cloud Service supports MQTT v3.1, MQTT v3.1.1 and v5.0 protocols. It is the first public cloud service in the world that supports MQTT 5.0, supports MQTT WebSocket services, and fully supports QoS0, QoS1 and QoS2-level MQTT messages.

Easy to deploy and manage

It only takes a simple operation to create a multi-node MQTT 5.0cluster with perfect configuration optimization and high availability in a few minutes, completely entrusting the complex operation and maintenance monitoring work to the EMQ X Cloud operation and maintenance team.

Charge by instance

Charge by cluster instance, rather than the number of messages, unlimited use of API and rule engine, the cost is clear and controllable. Provide a variety of specification examples, fully covering all levels of application scale.

Capacity estimation and expansion

The capacity is automatically estimated by the number of connections and message throughput, and the scaling plan is made through close monitoring. The cluster size can be smoothly adjusted with the business scale.

Highly available and private instances

Each deployment uses independent VPS, load balancing, DNS and other basic resources to ensure system security and stability.

Rule engine and real-time message codec

Built-in rule engine, you can dynamically write SQL to flexibly deal with device messages and event data, simplify the business development process; binary / special format message coding and decoding can be realized through the processing function of the rule engine or external services.

Integration with big data analysis and storage system

Through the rule engine, it is integrated with different big data analysis systems and storage systems, such as Apache Kafka,Apache Pulsar,PostgreSQL,InfluxDB,OpenTSDB and Redis.

Use restriction

The relevant restrictions on EMQ X Cloud depend on the number of connections purchased and the message downstream TPS, and the corresponding parameters have been closely tested.

Based on performance and stability considerations, the public cloud IoT Hub has imposed certain restrictions on device access and message sending and receiving calls. Here, the restriction information exposed by the existing public cloud IoT Hub is sorted out for reference.

Note: the "unlimited" of EMQ X Cloud in the following tables means that there are no technical restrictions, and the performance of related items depends on hardware restrictions. Current limit processing will be triggered when the performance consumption approaches the critical value. The specific data is subject to the actual usage scenario.

Limit the number of EMQ X Cloud public cloud IoT Hub connections per second 1000500 million 1000 single client subscription topics unlimited 101W single client subscription request 10101W single client uplink message speed unlimited QoS0:30~50 messages / second QoS1:10~20 messages / second QoS2: no support for single client messages downlink no limit 50mm 100 messages / s single client throughput bandwidth unlimited 1024KB single message length default 1024KB can apply to adjust 256KB offline elimination Maximum storage time will never expire 1 week Topic unlimited number of 50 users 100 permissions custom devices can only subscribe to / unsubscribe to their own Topic message publish subscribe / unsubscribe operation response time immediately 5: 10 seconds to support cloud platform

Domestic: Huawei Cloud has supported seven data centers in Shanghai, Guangzhou, Beijing, Aliyun Shenzhen, Shanghai, Hangzhou and Beijing.

If you need nodes in other regions, you can apply through a work order, and the application is expected to be supported within 1-2 weeks after the application is successful. (Chinese mainland region nodes only). A number of domestic cloud service providers are already planning to open their support in the future.

International: AWS now supports three computing centers in the eastern United States (northern Virginia), western United States (Oregon) and Europe (Ireland).

If you need AWS nodes in Asia or other regions, you can apply through a work order, which is expected to be supported within 1-2 weeks after the application is successful. (Chinese mainland region nodes do not support it). Azure and Google Cloud Platform are already planned and will be supported soon.
