There are multiple AWS topologies that enable redundancy of workflows, depending on the possibility of distribution or replication of the contribution streams.
SimplyLive production suite doesn’t support active redundancy and failover mechanism between main and backup instances, complete topology can be duplicated following one of the following schemes.
Availability Zone Redundancy
This approach involves deploying identical sets of instances across multiple Availability Zones (AZs) within the same AWS region. Each AZ is isolated from failures in other AZs, providing a robust layer of redundancy.
Region Redundancy
This approach involves deploying identical sets of instances across multiple AWS regions. This provides an additional layer of redundancy and disaster recovery, protecting against region-wide outages.
Replication of Contribution Streams
Depending on the source and nature of the contribution streams (e.g., live video feeds), you can distribute and replicate these streams across multiple instances and regions. This can be achieved using AWS Elemental MediaConnect or Secure Reliable Transport (SRT) protocol.
