At present, to deploy Tealeaf in a Softlayer/AWS/Azure environment, the Packet Forwarder component is installed on the web servers (or a proxy in front of them) to capture the network traffic. This traffic can only be delivered to a single peer, typically a PCA. If this PCA goes down, the traffic is lost.

It is possible to install a Software Packet Replicator (SPR) on a separate server to act as a delivery peer for the Packet Forwarder. This allows you to then forward the captured traffic to two PCAs configured in failover. However, whilst this guards against the scenario where one PCA goes down, the SPR itself then becomes a single point of failure.

There is therefore currently no way to configure the capture tier of Tealeaf in a cloud environment so that the failure of a PCA (or an SPR) does not cause data loss.
