Load Balancer

Features

Instance Performance

Single instance exclusive computing resources, public network IP independent, the IP number is not exceedable
Support Multiple Protocols

Supports four layers (TCP/UDP) and seven layers (HTTP/HTTPS) protocol load to meet different application scenarios.
Improve usability

Improve front-end access to two or more business nodes on the back end, improving cloud server availability
Easy to Scale Out

The backend node can freely increase or decrease according to the actual scene requirements.
High concurrent access

High concurrent service access is balanced by multiple nodes, or with different weights according to the specified weight value
Eliminate failure

Use multiple nodes to provide business access processing, thus avoiding the problem of single node failure causing business stagnation

Features

Multiple Protocol SupportMulti-protocol support to meet your diverse application scenarios

Specific protocol: Supports four layers of load balancing including TCP and UDP, and seven layers of load balancing including HTTP and HTTPS.

Certificate Management: Provides a centralized certificate management system for the HTTPS protocol to meet the needs of users for reliable and secure transmission.
Multi-level Disaster RecoveryProvide multiple levels of disaster recovery strategies and highly available user experience

Health Check: Checks the running status of the back-end cloud server periodically. Once the cloud server is detected abnormally, the traffic will not be forwarded to the abnormal instance to ensure availability.

Cluster Deployment: Cluster deployment, session synchronization between machines, machine failure and cluster maintenance are transparent to users, with no single point of failure.
Intelligent SchedulingMultiple scheduling algorithms and forwarding modes to enhance application deployment flexibility

Scheduling Algorithm: Supports weighted polling and minimum connection number scheduling algorithm, and can select the corresponding algorithm to allocate user traffic according to its own needs.

Domain Name URL Forwarding: Supports traffic scheduling based on different domain names and URLs to improve application system flexibility.
Session RetentionForward access requests from the same user to the same server for a certain period of time to achieve user access continuity

Source IP-based Session Persistence: Layer 4 (TCP/UDP) load balancing implements session persistence through IP addresses.

Cookie-Based Session Persistence: Layer 7 (HTTP/HTTPS) load balancing supports session persistence through cookies.
