Project background
With the optimization of the macro financial environment and the continuous improvement of the basic system of the capital market, the demand of clients is increasingly diversified, and the trend of fund environment develops rapidly. Business in
the old zone has gradually shown problems such as insufficient customer support ability, low business processing efficiency and slow technical operation and maintenance, which are in urgent need of updating and upgrading to meet the
requirements of changing external situation.
The high availability construction target of the business in the new zone
It is based on the consideration of business continuity and resource utilization that users choose the “application-level hypermetro” mode as the target in the construction of the new generation core business. Application-level active-active (activeactive),
as its name suggests, is a construction mode with higher utilization and availability than the traditional active-standby mode. Both data centers are Active and provide services.
Intra-city active – active deployment for new zone services
The global scheduling load balancer and regional load balancer work in coordination with the load distribution mechanism through a comprehensive health check mechanism. When some application nodes are abnormal, the regional load balancer
can automatically isolate the faulty node to ensure the high availability and stability of the service system in the region. In addition, the global load balancer combines the two data centers into an integral whole, enabling the two data centers to
simultaneously carry services and provide disaster recovery support for the other data center.
Value of the new partition service solution
Through the new partition business scheduling framework, each server node can run safely and independently without affecting each other. Meanwhile, the hot swap function of the node can be realized to facilitate system maintenance and
adjustment. When a data center fails, it only takes a few seconds for the data center in the same city to take over services. This multi-layer service scheduling framework provides the implementation conditions for the new generation of core service
systems from the global application high availability level across the center and the local application high availability level within the data center.
