Overview

AZURE SECURITY Load Balancing ensures critical applications remain high-performing, available, and resilient. It intelligently distributes traffic across backend servers, optimises egress path across multi-ISP links, and orchestrates failover across disparate data centers — complemented by SSL offloading to alleviate cryptographic burdens from application servers. The result is sustained application performance even during peak load or partial infrastructure disruptions.

Use Cases

• Mission-critical portals, business systems, and API gateways where downtime or latency is unacceptable

• Multi-ISP or multi-egress environments necessitating intelligent link utilisation and path selection

• Active-active or active-standby data center architectures requiring automatic failover and geographic load distribution

• Application servers under heavy TLS workloads that require SSL offloading and connection reuse for performance gains

Core Features

• Server Load Balancing — distributes inbound traffic across backend pools via configurable scheduling algorithms, with session persistence to maintain the integrity of stateful connections

• Intelligent Link Selection — Real-time selection of the optimal egress path based on link health, destination, carrier, and cost- efficiency policies

• Global Traffic Management — routes users to the most proximate or stable data center site, featuring automatic failover during a site outages

• SSL Offloading & Application Acceleration — Manages TLS termination, connection multiplexing, compression, and caching at the load balancer layer, relieving backend servers of cryptographic overhead

• Continuous Health Monitoring — probes backend nodes across multiple protocols, automatically removes unhealthy instances to ensure real-time visibility via operational dashboards.
