Introduction:
In our last post, The HStream Team: Challenges Make Things Charming | EMQ Global Recruitment Season 2021, we took a closer look at the EMQ HStream team. If the HStream database, as a new strategic product launched by EMQ, carries our imagination and hope for the future real-time data processing of the Internet of Things, then the product that this team is responsible for today has supported EMQ all the way to the present.
The EMQ X team is the subject of this article.
Q: How do you evaluate EMQ X products?
A: Hello, I’m Li Guowei, Product Manager of EMQ X. Currently, I am responsible for the design and planning of EMQ X Enterprise Edition.
EMQ X is an open source MQTT messaging middleware for Internet of Things. Its core competencies include single-machine high concurrency of millions, low latency of milliseconds, distribution, high availability and other features. It is widely used in global smart home, mobile payment, Internet of vehicles, mobile messaging and other cross-industry fields. It also supports flexible deployment in public cloud, private cloud, physical machine, Docker container and Kubernetes.
EMQ X open source project was founded in 2013. At present, the number of GitHub Star projects ranks first among similar projects in the world, and EMQ X is one of the projects with global influence in open source field in China.
On the basis of EMQ X Open Source Edition, we have launched Enterprise Edition to provide more professional business support and services for enterprise customers. The new rule engine in the enterprise version is used for message processing and storage in the Internet of Things, supporting more industrial protocol access, message codec, data persistence and many other enterprise-level functions, which can meet the higher security and real-time requirements of enterprise customers such as operators, Internet of vehicles and industrial manufacturing industries. It has attracted well-known companies including China Telecom, SAIC Volkswagen and State Grid.
Up to now, EMQ X has been used in more than 50 countries and regions, deployed 10,000 + clusters, supported more than 100 million device access, and provided strong support for the Internet of Things business of 10,000 + enterprise users. We also often receive praise from users in the community or some offline activities. Some users write EMQ X as standard messaging middleware in popular science books of Internet of Things technology. Some users use EMQ X for research and teaching purposes; Some users used EMQ X to put what they had learned into practice to create new ideas, and went to the popular Weibo search…… All these make our whole team feel especially gratified and proud.
With the development of the company’s strategy, EMQ X Enterprise Edition will also serve as the underlying core product to support the company’s internal EMQ X Cloud PaaS services and EMQ X Platform, providing more comprehensive services to the industry and the market with a new look.
Our starting point is MQTT messaging access. In the future, we will continue to focus on open source messaging and streaming software for 5G and the Internet of Things market, in combination with our existing edge computing products Nanomq and Kuiper, as well as our cloud streaming database products HStreamDB. Provide a one-stop solution for edge-to-cloud access, message exchange, and stream processing and analysis.
We are confident that we will be the world’s first class in this field and continue to maintain our leading and competitive edge. With the support of the open source community and the efforts of the EMQ X team, our creations and efforts are rapidly moving from technology to products, and from products to commercial services.
Q: What was it like working on the EMQ X team?
A: I am Deng Haigui, R&D Director of EMQ X Enterprise Edition. I joined EMQ in 2016 and have been working in EMQ X team for R&D.
EMQ X team is the core product development team of EMQ, focusing on EMQ X Internet of Things messaging middleware, leading the global 5G and Internet of Things messaging market cutting-edge technology development. With the world’s leading distributed Erlang/OTP platform and high concurrency technology architecture, we build the most trusted and highly reliable, massive concurrent MQTT Internet of Things messaging middleware software.

Ivy leaves yu big
Hello everyone, this is Yudai from Japan, a software engineer at EMQ.
I am responsible for developing our main product EMQ X, with Erlang. The team members are from different countries, so every two weeks we discuss and agree on the scope of work that is intended to be done during that period. This helps me working in a remote environment.
Recently I have worked on introducing a new configuration format to our product. We had decided to write our configuration files with HOCON, a superset of JSON and it is well used in Java and Scala. In Erlang, we did not have a parser for HOCON, so we had to make one. Erlang is the best language when you would like to design a concurrent application, but as you know, it is less common compared to other general-purpose programming languages. So our tasks often involve creating libraries rather than just using ones. In this way, we lead the community while trying to create the best MQTT broker in the world.
I am looking forward to seeing you at EMQ.
Dmitrii
Hello, my name is Dmitrii Fedoseev, I work at EMQ Sweden as a software engineer, in the domain of cluster scalability and robustness.
I originally come from Nizhniy Novgorod, Russia, but I am currently living in Stockholm, Sweden. I have worked on quite a few different areas in the past: in physics, telecom, finance and music industry.
I first started programming professionally back in the university, where I had developed software for simulating formation of crystals using GPUs. Using graphical processors for the general purpose computations was a new thing back then, and it was really exciting. That made me realize that working with technologies, that are less mainstream, gives me competitive advantage and allows to explore fresh and exciting ideas. Using a programming language that was so close to maths in nature, was really fascinating, and again, it made programming fun.
I accepted offer from EMQ without hesitation. EMQ’s dedication to the open-source, use of functional languages, and a team of extremely experienced and knowledgeable people from all around the world, was what attracted me. I believe that open-source movement is one of the greatest achievements of humankind, and I am grateful that now I can contribute to it full time.
Here at EMQ I can work on truly challenging problems and put all my skills to use. Our team is full of fantastic people, who come from Sweden, New Zealand, Japan and so on.
So if you enjoy solving challenging problems as much as we all do here, you’re welcomed to join EMQ.
