We took a hybrid head-based sampling approach that allows for recording 100% of traces for a specific and configurable set of requests, while continuing to randomly sample traffic per the policy set at ingestion point. This allowed us to increase total storage capacity without adding a new Cassandra node to the existing cluster.

Load balancing : Traffic is distributed across multiple servers to prevent any one component from becoming overloaded. Load balancers can detect when a component is not responding and put traffic redirection in motion. If a server fails, the load balancer redirects traffic to a replicated server in another cluster.
