Talking about the positioning of seven cows, seven Neu Yun storage CTO Han To said the current isss and PAAs boundaries have been blurred, customers become more rational, they are more concerned about the real value of cloud storage products. In such a market situation, seven of cattle to data for their own core value, and around the topic of data for the enterprise to provide a wealth of peripheral functions, such as upload and download CDN acceleration, data processing, analysis, custom computing platform and other services.
Since its inception in 2011, seven cattle currently has 150,000 enterprise and developer customers, while referring to the advantages of seven cattle, he said the focus on business, strong technical strength, unique product style and good service awareness is the key to the success of seven cattle. Of the more than 100 employees, the technical positions accounted for more than half of the seven cows. Core technology team from Jinshan, Sheng, Baidu and other companies, its multi-data center WAN distributed architecture, dual data center of the mutual standby, low-cost, high availability of the redundant algorithm, such as the core technology are seven of cattle in the cloud storage field constantly polished, optimized, He admits that seven cows since its inception three years, can say that only one thing that is stored. This article comes from the interview arrangement of Han To.
Seven Neu Yun storage CTO Han To
Seven cattle team, positioning, user sizeCSDN: First introduce yourself and seven cows, the current technical team situation?
Han To: My first job after graduating in 2007 in Jinshan software, into the then just established Jinshan laboratory, mainly involved in the distributed Storage System research and practice. 2008 Jinshan Fast Start Project, I led the storage team led the fast disk first Edition storage System design, development and on-line. Then I went to Shanghai to join an entrepreneurial team of online games, fully involved in the game server architecture, development and 3D rendering. 2011 Seven Neu Yun storage set up, I was fortunate in the beginning of the venture to join, participate in the seven Neu Yun storage product design, development and operation, and in seven cattle work so far.
Seven cows currently has more than 100 employees, technical positions accounted for more than half of the products and functions into more than 10 departments, the core technical team from Jin Shanyun, Sheng, Baidu and other companies. Seven cows have gone 3 years since the start of the venture, in the past 3 years, we have built the leading cloud storage products in the country, gained the trust of 150,000 of enterprises and developers, and became their cloud storage providers, uploaded hundreds of millions of files a day, and the independent active IP number has already covered half of China's netizens.
CSDN: What do you think about the current situation of cloud storage market at home and abroad? What is the location of the seven cows?
Han To: Since Amazon launched the AWS product, the market for cloud storage has been growing rapidly, with the increasing ease of use and quality of cloud storage products and falling costs, more and more enterprises have chosen to build their own business using cloud storage or use cloud storage instead of traditional storage solutions, especially in the last 1 years , with the advent of the Internet in traditional industries, we have observed that the market capacity of cloud storage is expanding very rapidly, and we believe that with this wave of change, the market of cloud storage will reach the tipping point of the outbreak.
From the product, the cloud storage product shape has developed to today, and 2007 years or so the concept has just arisen very different, on the one hand on the market there are many PAAs products based on cloud storage, so that developers can more convenient use of cloud storage, on the other hand, IaaS vendors are also floating, Launched a number of more targeted, more vertical products, from today's market situation, the ISSS and PAAs boundaries have been blurred, customers have become more rational, they are more concerned about the real value of cloud storage products to them, these are cloud storage real landing, As a signal to the globally recognized IT infrastructure.
In such a market situation, seven cattle with data for their core value, and around the data this theme for the enterprise to provide a wealth of peripheral functions, such as uploading CDN acceleration, data processing, analysis, custom computing platform business, take over the data generation, upload, storage, processing analysis, download and other processes, Strive to provide enterprises with a full life cycle of data management services.
The seven-cow product application scenario is very broad, and it can be said that all scenarios involving the storage of unstructured data can use seven of cows, such as pictures, video type of app, static website or website static data, UGC class business, online education, video surveillance, live, SNS, music business, backup and cold data storage, network disk and so on.
CSDN: Seven cattle Current user size, what are the heavyweight customers?
Han To: As mentioned earlier, seven cows currently have 150,000 enterprises and developer customers, add about hundreds of to thousands of customers, in fact, there are some heavyweight and star enterprises, such as the United States map, camer360, poor tour, Haikang, peas, such as the Mo. From the customer's point of view, we can provide them with:
First, in terms of cost, one is to reduce development costs, enterprises do not have to develop a set of storage systems themselves; One is to reduce operational costs, managed cloud storage to complete the operation-free dimension; One is the sunk cost of hardware, on-demand, one-time investment is small, very suitable for small and medium-sized enterprises and large businesses just start business.
Second, the benefits, the use of more professional services, can enhance the reliability and availability of data, upgrade upload download speed, can easily use seven of cattle around the data processing, custom computing, data statistics, reports and other services, which provide developers with great convenience.
Core AdvantageCSDN: Cloud storage has always been a battleground for cloud giants at home and abroad, what do you think are the advantages of seven cows in the cloud storage field?
Han To: Our advantages can be discussed in several ways:
The first is focus. There are a lot of giants at home and abroad that are involved in cloud storage, but there are very few companies like seven cows that specialize in this area. Storage is a big topic, want to do well, do deep not easy, need to devote a lot of time and energy, need to have enough patience, constantly to polish, optimize, need to withstand loneliness, not be disturbed by the temptation of the outside world, do a lot of seemingly boring but very valuable research and exploration of the former academic. Seven cows in this respect to do very well, we set up three years, can say that only one thing is stored, so in the storage of this field, we can achieve a 100% self-confidence, never lost to any industry giants.
There is also the technical strength. Our core team is one of the earliest research in distributed storage of a group of people in this field has been for many years, but also for different businesses have done a lot of storage systems, so we have a storage system design and development have accumulated a lot of experience. Thanks to these experiences, at the beginning of the seven cattle creation, we can use three months of time on the line of the first version of the products, in the next three years, we do the average weekly product update motions, through the three years of technology accumulation, continuous iteration, grinding, naturally formed in the market a very competitive product.
The 3rd Advantage I think is seven cattle unique to do product style. Cloud storage is a relatively abstract product, its interface is a variety of APIs, from this point of view, cloud storage products are not easy to grasp, in this issue, seven cows have their own unique methodology: User demand-driven product iterations. Just mentioned that at the beginning of the seven cattle creation, we use three months of time online the first edition of products, this version of the product is very simple, only to provide the most common upload, download function, in this version of the product base, we introduce seed customers, customers in the use of the process will often put forward their own unique needs, We will use the fastest speed to respond to these needs, the need to abstract, and in the product implementation, this time is very fast, usually two or three days can be online, in this process, the product will naturally be perfect. With the perfect product, will attract more customers, more customers will bring more demand, help us to improve their products, this is a very good virtuous circle. On the aesthetic of products, we never underestimate ourselves, and will not be arrogant, but all follow the demand and move, this methodology has been used so far, to help seven of cattle products in the market has been in a leading position.
4th, I want to talk about service consciousness. The core world view of cloud storage I think it is a managed word, "managed" in the word "tube" is actually refers to the service, so service awareness is the operation of a cloud storage business is one of the core elements. Seven cows have always attached great importance to customer service, from the beginning of the venture, we have set up a 7*24-hour technical support, operation and development of the joint customer support system, to do the first time to respond to and deal with customer issues, for important issues, CEOs and other senior executives will even personally provide one-on-one customer service, For small and medium-sized enterprises and start-ups in need of help, our architects will have an in-depth understanding of each other's architecture and provide corresponding architectural recommendations and access scenarios. A good sense of service to make up for some of the products on the corner, so that seven cattle really become the intimate data steward, I think this is also our ability to lead other cloud storage vendors is a key reason.
Technical FrameworkCSDN: Noting that you have a state-of-the-art, distributed architecture and storage technology in the cloud storage area, can you share some of the technical, architectural, and practical experiences you have used in this area?
Han To: Technically we are proud of a lot of points, I choose a few easy to understand the examples.
The first is the WAN distributed architecture for multiple data centers. Seven cows the use of multiple data center technology has two purposes: one is the storage of multiple data centers, one is the upload of multiple data centers, download acceleration. Seven cows in the country have a number of core storage room, the size of these rooms are relatively large, used to store customer data, customers can according to their own business characteristics, the initiative to choose one or more storage room use, or do not care about the structure of multiple storage room, completely to seven cattle system to dispatch data, This technology provides customers with the greatest flexibility, for example, the network disk class business, localization characteristics are very obvious, end users are usually in the same city upload and download, then we can support the end of different regions using different regions of the storage room, such as Beijing's clients using Beijing's storage room storage, Shanghai's clients use the Shanghai storage room storage, so that the location of data storage and use of the location recently, get the best upload, download speed. There is also a kind of business without showing the geographical characteristics, for example, micro-blog sharing applications, data upload and download location is usually not together, the data by the customer's own scheduling is very troublesome, then you can use seven of cattle system to schedule data, and do not care about the specific data stored in which room. We will store the data to the nearest room, and then asynchronously dispatch the data to other rooms based on the reading, including hundreds of acceleration nodes built with CDN to get the best rate of visit.
Another interesting thing is the mutual provisioning between the two data centers. The risk of storing data in a data center is high, and if a data center loses power, breaks the net, causes data to be unavailable, and if a data center has a catastrophic accident and can cause data loss, seven of cows use the dual data center's interoperability technology. We interconnect two data centers with bare fibers, and when users upload files to a data center, the system asynchronously synchronizes the file data and the related original data to another data center that is being made available to it, so that when a data center failure occurs, we will enable different contingency plans according to the level of failure and switch the request to the data center with which it is being prepared.
Another important factor is the Low-cost, high-availability redundancy algorithm. The core of the technology storage system is cost and reliability, and the two are a pair of contradictions, want to reduce the risk of losing data, it is bound to increase the number of copies of each copy of the data, and increase the number of copies of each copy of the data, but also bound to increase the cost, seven of cattle using the EC redundancy algorithm to balance this contradiction. This algorithm splits a piece of data into m and converts this m data into a multiple linear equation group, calculate n checksum data, and then store this m+n data, in the stored m+n data, any one or more of the data damage, we can through the multivariate linear equations to calculate the corrupted data back, It is easy to conclude from this principle that a system using the EC redundancy algorithm supports up to N data corruption without losing data. Seven cows use some of their own unique technology, the M and n are large numbers, M is far greater than N, so that the system's backup number is very low-(m+n)/m (m larger than N), And the reliability is very high-can damage n data (n is also a large number).
Safety AssuranceCSDN: In particular, enterprise-class customer focus on security can be said to be 0 tolerance, how do you guarantee?
Han To: The Enterprise to the security appeal is usually two aspects, one is the data not to lose, the second is the data does not leak. In the case of no loss of data, I talked about seven cows. Using EC redundancy algorithm to obtain very high data reliability, and on the basis of the introduction of dual data center interoperability to avoid a single room catastrophic accident, through these efforts, seven cattle to protect the enterprise's data 0 lost.
In the data not leakage aspect, on the one hand seven cows through the firewall, the fortress machine, the security audit, the warning mechanism, the inside and outside network DMZ isolation, the file data to break up the storage, the metadata and the file data separation storage and so on the technology and the means guarantees the security, on the other hand The operation of any internal personnel is through strict authorization and audit, ensuring that internal staff are not exposed to the production system data.
