Elastic Load Balancer
ELB(Elastic Load Balancer) automatically distributes incoming traffic across multiple servers to balance their workloads, increasing service capabilities and fault tolerance of your applications.
Provide basic security protection capabilities, customers can expand the number of back-end servers according to the number of requests
Redundant design to avoid the impact of single point of failure.The activation and deactivation of the service node does not affect the current service
Distributed clusters have high performance and can meet large-scale request distribution scenarios
Quickly low-cost deployment services; low maintenance costs
Support public/private network
services, and provide Layer
4 (TCP) and Layer 7 (HTTP)
network services
Support weighted round-robin
scheduling algorithm, you can
select corresponding strategies to
distribute network traffic(support
domain and URLs) to improve
application system flexibility
Distributed clusters perform health
checks on servers according to the
configuration and automatically
isolate the servers with abnormal
status
Supports session retention for
both TCP and HTTP protocols,
and distributes requests from the
same client to the same server
