s average request latency.</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 aggress
