Analysis of cloud IoT platform

Analysis of cloud IoT platform

Cloud platform, also called cloud computing platform, refers to services based on hardware resources and software resources, providing computing, network and storage capabilities.

The war on cloud platforms has intensified. Since Amazon and Google have gradually begun to compete globally, the domestic cloud computing market has also become fiercely competitive. The major domestic manufacturers ranked according to the number of users are: Alibaba Cloud, Tencent Cloud, Xinrui Cloud, Huawei Cloud, Baidu Cloud...

Alibaba Cloud

Founded in 2009, Alibaba Cloud is the world's leading cloud computing and artificial intelligence technology company. It is committed to providing safe and reliable computing and data processing capabilities in the form of online public services, making computing and artificial intelligence an inclusive technology. Alibaba Cloud serves leading enterprises in many fields such as manufacturing, finance, government affairs, transportation, medical care, telecommunications, and energy, including large corporate customers such as China Unicom, 12306, Sinopec, PetroChina, Philips, and BGI, as well as star Internet companies such as Weibo, Zhihu, and Smartisan Technology. Alibaba Cloud has maintained a good operating record in extremely challenging application scenarios such as Tmall Double 11 Global Carnival and 12306 Spring Festival Ticket Purchase.

Alibaba Cloud has deployed efficient and energy-saving green data centers around the world, using clean computing to provide a steady stream of energy power for the new world of Internet of Everything. Currently, the service areas include China (North China, East China, South China, Hong Kong), Singapore, the United States (Eastern United States, Western United States), Europe, the Middle East, Australia, and Japan.

In 2014, Alibaba Cloud helped users resist the largest DDoS attack in the history of the global Internet, with peak traffic reaching 453.8Gb per second. In the Sort Benchmark 2016 sorting competition CloudSort project, Alibaba Cloud broke AWS's record of 4.51$/TB with a sorting cost of 1.44$/TB. In Sort Benchmark 2015, Alibaba Cloud used its self-developed distributed computing platform ODPS to complete 100TB data sorting in 377 seconds, breaking Apache Spark's world record of 1406 seconds.

Tencent Cloud

Tencent Cloud itself also has a large-scale layout in social networking and gaming, so Tencent Cloud host can also be among the top based on its own huge number of users.

The advantage of Tencent Cloud Host lies in the green check certification of QQ chat window and Tencent Cloud’s experience and professionalism in the field of entertainment and games. It also has better compatibility in social applets such as QQ/WeChat.

Specifically, it includes basic cloud services such as cloud servers, cloud storage, cloud databases, and elastic web engines; Tencent's overall big data capabilities such as Tencent Cloud Analysis (MTA) and Tencent Cloud Push (Homing Pigeon); and cloud-linked social systems such as QQ Internet, QQ Space, Weiyun, and microcommunity. These are the differentiated advantages that Tencent Cloud can provide to this industry, creating a high-quality Tencent Cloud technology platform that can support various Internet usage scenarios.

New Ruiyun

Xinrui Cloud is considered the leader among the rising stars. The impression of focusing on domestic products has made Xinrui Cloud's active IP growth rate reach 219% in 2019, which reflects its strong strength in the enterprise-level market and Xinrui Cloud's commitment to the cloud market.

Xinrui Cloud mainly deals with large enterprises (such as state-owned enterprises, public institutions, etc.). It is regarded as an exclusive user group of domestic forces (but personal business is also very good). Xinrui Cloud's own technology is another existence besides BAT that is difficult to shake its position.

Huaweicloud

Since March 2017, Huawei has specially established a Cloud BU to build and provide a trustworthy, open public cloud with global online and offline service capabilities. As of September 2017, Huawei has released a total of 85 cloud services in 13 categories. In addition to serving domestic enterprises, it also serves many enterprises in Europe, America and other regions around the world. 

Huawei Cloud is based in the Internet field and relies on Huawei's abundant capital and strong cloud computing R&D capabilities to provide Internet value-added service operators, large, medium and small enterprises, governments, scientific research institutes and other enterprise users, including basic cloud services such as cloud hosting, cloud hosting, cloud storage, supercomputing, content distribution and acceleration, video hosting and publishing, enterprise IT, cloud computers, cloud conferencing, game hosting, application hosting and other services and solutions.

AmazonAWS

Amazon Web Services (AWS) is a professional cloud computing service provided by Amazon. It was launched in 2006 to provide IT infrastructure services to enterprises in the form of web services, commonly known as cloud computing. One of its main advantages is the ability to replace upfront capital infrastructure expenses with lower variable costs that scale according to business development.

Users can choose the corresponding type according to their needs to help you maintain the appropriate control balance while avoiding meaningless heavy work. Currently, many customers use AWS to build complex applications. Due to the use of many users, this also accelerates AWS's pace in machine learning, artificial intelligence, Internet of Things, and serverless computing.

Services provided by Amazon Web Services include: Amazon Elastic Compute Cloud (Amazon EC2), Amazon Simple Storage Service (Amazon S3), Amazon Simple Database (Amazon SimpleDB), Amazon Simple Queue Service (Amazon Simple Queue Service), and Amazon CloudFront.
