Deploying real-time communication (RTC) workloads on Amazon Web Services’ (AWS) cloud-based infrastructure ensures scalability, elasticity, and high availability. Here's why AWS is ideal for RTC applications:

  • High Availability with Availability Zones: 

AWS Regions are divided into Availability Zones, each with its own redundant power, cooling, and network infrastructure, forming isolated failure domains. Running workloads in multiple Availability Zones ensures resilience even in rare complete zone failures.


  • Multi-Availability Zone Deployment:

For high availability and failover, it's recommended to deploy RTC workloads across more than a single Availability Zone. This architecture guarantees uninterrupted service in case one zone becomes unavailable.


  • Workload Security:

AWS includes workload security in its architecture to help secure workloads and ensure compliance with regulations like POPIA, GDPR, HIPAA, and PCI-DSS.

Incorporating AWS into your RTC application architecture guarantees real-time communication with reduced cost, improved agility, and elasticity while meeting stringent latency and availability requirements.
