.</p><p>Istio’s use of Mixer has two main benefits in terms of overall system availability and latency:</p><ul><li><p><strong>Increased SLO</strong>. Mixer insulates proxies and services from infrastructure backend failures, enabling higher effective mesh availability. The mesh as a whole tends to experience a lower rate of failure when interacting with the infrastructure backends than if Mixer were not present.</p></li><li><p><strong>Reduced Latency</strong>. Through aggressive use of shared multi-level
