Self-service application can be completed within minutes, without requiring administrator’s intervention; support flexible configuration of multiple forwarding policies, and realize advanced, custom forwarding control functions.
The typical private-network ELB instance is subordinate to a network domain (DMZ/SF/PTR) of VPC. Its architecture is more secure, and its deployment structure conforms to financial security regulations.
The ELB instance provides the service IP address as a unified interface for client access. Each ELB instance can be configured with multiple listeners to provide multiple-port listening services for the same service IP address. Each listener can be configured with a specific server resource pool, or the same server resource pool can be designated by multiple listeners.
For high-concurrency business scenarios with high peak traffic, such as time-limited promotions and periodic activities, use ELB to distribute traffic to business systems, scale external service capabilities of application systems, and flexibly control back-end resources in real time. The practice of pay-as-you-go is adopted to reduce construction and operation & maintenance costs.
