Capability Level Expansion of Website Service

With the growth of business and website traffic, the service capacity of a single WebServer is limited and it is difficult to adapt to the scenario of high concurrent access. Through the load balancing service, multiple WebServer concurrent services can be provided to achieve the effect of business level expansion.

High Availability of Services

The service is deployed on a single host. Network problems, hardware problems, and program bugs and others causes can cause the service to be unavailable. If you want to further improve service availability, you can use load balancing services to deploy multiple identical cloud servers at the back end. Thus, the service availability will be greatly improved because the failure of a single module will not affect the service itself.

Typical Scenarios of Public Network BLB

You can bind EIP to BLB to realize public network traffic load. The typical scenarios of public network BLB are as follows:

• Community portal: If one BCC instance has high access pressure. You can purchase multiple BCC instances and deploy load sharing to implement traffic distribution.
• Mobile application development: You can buy multiple BCC instances and deploy load balancing. You can deploy the same update package on different BCC instances to meet needs for mobile application update and user growth.
• E-commerce website users: E-commerce users often experience instantaneous traffic peaks when conducting promotional activities. Buying multiple BCC instances and deploying load sharing, and setting bandwidth peaks to balance traffic between servers can effectively alleviate the access pressure on the website and ensure its stability.

Typical Scenarios of Intranet BLB

BLB provides the intranet service address by default. The typical scenarios of intranet BLB are as follows:

If the user has multiple applications, such as using a web server to connect to the public network, the database server can only be accessed by the web server. A private network BLB can be deployed between the web server layer and the database server layer to balance the access traffic between the web layer and the database layer.
