Envoy – Service Proxy

Envoy is a high-performance edge and service proxy designed for cloud-native applications. It provides advanced load balancing, observability, and security features for microservices.

Key Features

• L7 Proxy: HTTP/2 and gRPC support
• Service Discovery: Dynamic configuration
• Load Balancing: Multiple algorithms
• Observability: Built-in metrics and tracing
• mTLS: Automatic certificate rotation

Installation

Install Envoy on Ubuntu:

sudo apt install apt-transport-https gnupg2 curl lsb-release
curl -sL https://deb.dl.getenvoy.io/public/gpg.8115BA8E629CC074.key | sudo gpg --dearmor -o /usr/share/keyrings/getenvoy-keyring.gpg
echo "deb [signed-by=/usr/share/keyrings/getenvoy-keyring.gpg] https://deb.dl.getenvoy.io/public/deb/ubuntu $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/getenvoy.list
sudo apt update
sudo apt install envoy
