This article shows you what the unique technical advantages of Snowflake are, the content is concise and easy to understand, and it will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Cloud primordial

Snowflake puts forward the concept of data-warehouse-as-a-service (DaaS), which can be simply understood as a SaaS service that is native to the cloud and focuses on data warehouses. The cloud-based nature of Snowflake is not the same concept as many data warehouse providers support cloud services. Although other cloud service giants, such as Oracle,Teradata,Netezza, support the cloud more or less, because of the limitations of their own product architecture, they often prove to be unable to solve the various data needs and problems faced by many modern enterprises.

Unique underlying architecture

Snowflake proposes a unique architecture for the separation of storage, computing and management services. Snowflake put forward the concept of Multi-cluster and shared data on the basis of Shared-nothing. The key to this architecture is the complete separation of storage and computing, which essentially solves the pain point of the traditional architecture.

From the storage layer perspective, Snowflake automatically divides all tables into nearly fixed-size micro-partition to support more advanced time travel and data sharing functions. Even if you clone the database, you have two databases logically, while the underlying storage still has only one version. From the computing level, Snowflake defines computing power in terms of T-shirt size, which greatly simplifies the process of provision compared with other cloud computing resources. Users can increase or reduce computing resources at any time to meet the demand, and the data seen by these different computing resources are all from the same version. From the perspective of the service layer, it is another Snowflake service layer that I think is very independent. It consists of a number of global services, covering tasks such as operation management,optimization,tuning,security,availability,metadata,caching. It solves the problem of ease of use of data warehouse and greatly reduces the cost of management and operation and maintenance, which can not be compared by other competitors.

Technically adhere to the principles of neutrality and openness

In the United States, Amazon AWS, Microsoft Azure and Google Cloud are cloud service giants with strong competitiveness, ecologically sound platforms, large infrastructure and rich customer resources. Snowflake opens up these public cloud platforms to provide neutral, pay-on-demand services, and provides customers with greater flexibility in data migration and sharing. Adhere to the principle of open data sharing, unite data providers, partners and customers, the more customers adopt the platform, the more data can be exchanged with other customers, partners and data providers, and enhance the value of the platform to all users.

Is there any company similar to Snowflake in China? in fact, similar products are more called data center in China, and 2019 is the first year of data center in China. Recently, we found that there is a domestic company that has been building data center products for digital transformation since its establishment 7 years ago. This company is called Guoyun data. Recently, Ma Xiaodong, founder of Guoyun data, was interviewed by Yiou net and other media and marked its data center as the Chinese version of Snowflake. The data provided by Guoyun data is similar to Snowflake in terms of technology.

The data center is derived from Ali's top-level technology architecture, but is not bound to any cloud platform, data tool or database, and can be compatible with customers' own business systems without having to pull them down and start all over again, thus saving enterprise costs and improving business operation efficiency. The data center supports the secondary development based on the upward application of the data center, which not only realizes the joint use of technology, business, management and other personnel, but also ensures the security of customer use and data security. In addition, Guoyun data, like Snowflake, used cloud native technology, storage separation, read-write separation technology at the beginning of the data center planning. After 7 years of optimization and upgrading, it has achieved the extreme.

The above is what are the unique technological advantages of Snowflake. Have you learned any knowledge or skills? If you want to learn more skills or enrich your knowledge reserve, you are welcome to follow the industry information channel.
