<p class="p_Normal">Istio is an alternative to Linkerd and represents a dedicated level of infrastructure called Service Mesh. It helps manage communication between services, handle retries, timeouts, and automatically encrypt connections.</p>
<p class="p_Normal">Installing the Istio add-on component provides balancing of gRPC traffic when scaling BRIX services. It also provides telemetry — success rates, latencies, etc.</p>
<p class="p_Normal">Service Mesh is a necessary component to enable support for scaling services on the side of the BRIX application. Without an installed Service Mesh, traffic balancing when scaling BRIX microservices will not work correctly.</p>
<p class="p_Normal">Installation consists of five steps:</p>
<p class="p_Normal">Istio — является альтернативой Linkerd и представляет собой выделенный уровень инфраструктуры, называемый Service Mesh. Он помогает обрабатывать связь между сервисами, повторные запросы, тайм-ауты и автоматически шифровать соединения.</p>
<p class="p_Normal">Установка компонента дополнений Istio обеспечивает балансировку gRPC-трафика при масштабировании сервисов ELMA365. Также он предоставляет телеметрию — коэффициент успешности, задержки и т. д.</p>
<p class="p_Normal">Service Mesh является необходимым компонентом для включения поддержки масштабирования сервисов на стороне приложения ELMA365. Без установленного Service Mesh балансировка трафика при масштабировании микросервисов ELMA365 будет работать некорректно.</p>
<p class="p_Normal">Установка состоит из пяти этапов:</p>
