Before the text begins, mention a very interesting phenomenon. What is the reason for the fact that Amazon, the world's leading provider of cloud computing, is a aliyun of electricity from the electrical quotient of China, which is doing well in Chinese cloud computing?

Any technology from concept to maturity, is from the process of satisfying application requirements constantly improve, need to go through a lot of application scenarios to temper and polish. With the rapid growth of electronic commerce in the world, the IT system of electric power provider has put forward the demand of large scale storage, access and data processing. In the daily business, the IT system of the electric business in addition to the high standard of system stability and security, but also need low-cost response to burst traffic, provide flexible computing resources, these requirements drive cloud computing technology mature. Aliyun Cloud computing, first of all to meet Ali the needs of all types of electrical business application scenarios to start, with a mature solution to meet the various types of electrical business problems encountered.

A very typical business demand in the field of electricity is the surge of traffic caused by promotional activities. For example, in the Double 11 promotion, under the impact of high traffic, the electrical business system may encounter the following challenges:

1, the instantaneous number of visits may be 50 times times the usual;

2, the network bandwidth is occupied, the user response is very slow;

3, the machine load high even when the machine;

4, the database pressure is too large to cause service is not available;

In the 2012-year double 11, cat and Taobao platform on a total of 19.1 billion of turnover, orders 105.8 million pens, supporting various types of transactions billions of levels, various access inquiries to reach Bai. One of the poly Stone Tower processing orders more than 20% of the total number of cats, increased 20 times times than usual, support 12,000 days of cat merchants and 170,000 full network sellers, but also achieved 0 failures, 0 lost orders.

Poly Stone Tower is the cat and Aliyun jointly launched by the cloud computing as the bottom, for the electric dealers and all kinds of electronic business providers to provide IT infrastructure and data Services platform. This is also Ali's cloud computing technology in the field of E-commerce for the first large-scale combat, effective proof of cloud computing in response to the power of the business challenges. Before doing a thorough solution discussion, we can look at some of the applications of the http://www.aliyun.com/act/convoy.html, ISVs, and E-commerce merchants deployed separately on cloud computing: the

The value of cloud computing

So how does cloud computing help dealers deal with these challenges? First, talk about the core value of cloud computing.

One of the core values of cloud computing is to solve the problem of building large-scale distributed systems for customers. Cloud computing services provide a large enough computing power and storage capacity, any customer can obtain 10,000 CPU core computing power in 10 minutes, 10P storage capacity, precisely because cloud computing products in computing and storage of the tremendous capacity, The software system of the electric dealer can deal with 50 times times of the traffic growth in the double 11 period calmly.

The core value of cloud computing is to make the overall cost of users significantly lower, customers do not need to provide idle resources for peak traffic, ready to release unused resources. Plus Aliyun is based on the actual use of resources to collect fees, greatly reducing the overall cost of users. Electric dealers no longer need to purchase dozens of times times the server and bandwidth, as long as the two 11 day, temporarily increase the cloud computing products and services in some configuration, after the double 11 and then tune down, so that only 1 days of peak access to pay the cost.

In general, Aliyun Cloud computing provides large computational power and storage capacity, and charges only according to the actual use of resources, for the electric dealer in the double 11 similar promotional activities to calmly respond to the surge of traffic and low-cost.

For small and medium sized Internet enterprises and electric business enterprises, the construction of their own IT systems, will be not a small cost. The value of Aliyun's cloud computing is that it can provide a unified solution, so that the electrical business and more small and medium-sized enterprises in the cloud computing platform to deploy applications, through the Aliyun unified operation, cloud Platform security mechanism to ensure the stability and security of the system.

How to use Aliyun cloud computing products to build an electrical business system

Aliyun can now provide complete solutions for the electric dealers, the current product line is divided into two categories: flexible computing and large-scale storage.

Flexible computing products include cloud server ECS, load Balancing Service SLB, cloud monitoring, Cloud shield. ECS and SLB together to provide users with flexible computing capabilities, cloud monitoring to help customers better understand the operation of the service, Yun Dun is a security product, making customer service more secure.

Large-scale storage offerings include relational database services RDS, open Storage services OSS, open structured Storage service OTS. RDS is suitable for storing traditional relational data, and OSS is suitable for storing key-value forms of data, OTS suitable for storing large amounts of single table data.

Based on the above products and services, electrical business customers can usually take the following way to build their own Internet services, as shown in the following figure:

1, SLB is an external access to the entrance, provides the ability to expand computing capabilities, by setting up virtual IP, will be located in the same data center of multiple cloud server resources into a high-performance, highly available application service pool, and then according to the application characteristics of the network request from the client to distribute the cloud server pool, At the same time, SLB also play a role in enhancing the anti attack capability of cloud server pool.

2, HTTP application Services cluster based on SLB and ECS to build, when the traffic growth quickly, add more ECS nodes to the SLB, and then large traffic is not afraid.

3, often need to update the structured data stored in RDS, the bottom of the RDS using Ssd+fushionio hardware devices, can handle 50,000 of IOPS, easy to deal with the database access pressure

4, do not need to update the image, video, files and other static content stored in the OSS, OSS provides 10PB level of storage capabilities, no need to worry about the growth of data volume.

5, RDS,OSS,SLB maximum network bandwidth can reach hundreds of gbps,ecs network bandwidth can also be in the management console dynamic adjustment, network bandwidth is not enough to quickly solve the situation.
