Load Balanced Stream Manager
Stream manager application supports load balancing (at the moment for AWS only). This means that in an occasion of anticipated heavy traffic, you can set up more than one stream manager behind the cloud platform's load balancer service. This is ensure that traffic request such as (broadcast / subscribe) is evenly distributed between multiple stream manager instances to prevent flooding of requests on a single instance.
Multiple stream managers still interact with a single shared database. So if your traffic needs will be high make sure to set-up a higher configuration database instance to host the RDS.
Since the time synchronization between multiple stream managers is based on UTC it is important that the system clock of the stream manager instance be accurate and managed by a reliable NTP service. Administrator must setup NTP service on the VM instance prior to setting up streammanager.
