Additionally, AWS customers can use tools such as AWS App Mesh, which is built on Envoy to set up a service mesh for their applications, providing deep visibility into application performance, and making it easier to manage distributed services.

What is Nginx and envoy?

Nginx and Envoy are two popular open source web-proxy solutions. Nginx (or “Engine x”) is a reverse proxy, web server, and a software load balancer for HTTP, TCP, UDP, and other types of applications.

It can be used to route traffic and quickly scale out incoming requests. Envoy is an open source edge and service proxy that provides a unified entry point for all types of traffic including HTTP/1. 1 and HTTP/2 traffic.

Envoy functions as a load balancer, load router, and service mesh. It provides increased visibility, agility, and flexibility for an organization when deployed as a service mesh, offering advanced resiliency, security, and routing capabilities.

Together, Nginx and Envoy are powerful solutions for web-proxy applications, enabling organizations to quickly scale up incoming requests and provide a unified entry point for all types of traffic.

Is envoy proxy or reverse proxy?

Envoy Proxy is a high performance open source edge and service proxy, designed for cloud-native applications. It functions as a reverse proxy and provides the ability to manage communication between clients and back-end services with dynamic configuration updates.

Envoy supports dynamic service discovery, session affinity for client-specific routing, health checks, timeouts, and other important proxy capabilities. It also features robust observability with an easily extensible data plane API and provides observability utilities such as statsd and tracing.

Its versatile nature and routing abilities allow it to be used in many different types of services, from edge proxies, to service meshes, to platform-as-a-service. It is designed as a lightweight proxy with a focus on modern protocol support and performance which makes it well suited for distributed architectures.

Is Envoy proxy a load balancer?

No, Envoy Proxy is not a load balancer. Envoy is a proxy, or a “service mesh” as some people refer to it. It is a layer 7 proxy designed to route traffic between services, making requests more efficient and providing security.

Envoy’s main purpose is to make services accessible and secure, ensuring that requests are routed to where they need to go and that traffic is restricted to authorized services. While Envoy does support load balancing, it is not its primary purpose.

Envoy specializes in routing and its true purpose lies in providing authentication, authorization, observability, and policy enforcement.

Is envoy faster than NGINX?

Envoy and NGINX are both fast and optimized for different purposes. Envoy is a type of proxy specifically designed for service-to-service (microservices) communication and works with HTTP, TLS, and gRPC protocols.

It is known for being highly performant and configurable with its own special features, such as dynamic rate-limiting, circuit breaking, and load balancing. NGINX on the other hand, is a web server and reverse proxy that works with web protocols like HTTP and HTTPS.

It is known for high performance, load balancing, and handling a large number of concurrent connections.

So to answer the question, it is difficult to say definitively which is faster. Ultimately, the performance of either depends on the application and the environment. NGINX might have an edge when handling a lot of web requests, while Envoy might outperform NGINX in microservices-oriented applications.

Is API gateway a reverse proxy?

API gateway is a type of reverse proxy and acts as a middleman between clients and the backend services. It is the entry point that provides access to multiple services and functions, typically through the creation of a proxy system.

The API gateway acts as a single entry point for all of the services so, rather than making multiple requests, each client can send a single, unified request to the API gateway. It helps in managing ‘N’ number of services and routes requests to particular services as per the user needs.

The API gateway also handles authentication, authorization and encryption for accessing services, and also provides client applications with additional features like analytics, caching, and rate limiting.

Additionally, an API gateway might also provide rich capabilities like combining multiple requests into one and returning data from multiple services and domains.

What port does envoy run on?

Envoy runs on port 9901 by default. It can also be configured to run on any other available port. For example, you can configure it to run on port 8080 by setting the “–local-domain-socket-address” option to “localhost:8080”.

When setting this option, ensure that the port is not already in use or blocked by a firewall. Additionally, any other services running on the same machine must also be bound to a different port. You may need to use network tools such as netstat or lsof to determine if another service is already running on the same port as Envoy.

Is envoy a Layer 7?

No, Envoy is not a Layer 7. Envoy is a service mesh technology that is composed of an edge proxy and a control plane. It is based on the the Envoy Proxy project and allows users to connect, secure, control, and observe services so that they can easily create a service mesh for their applications.

Envoy acts as a Layer 4 (transport layer) and Layer 5 (session layer) proxy allowing users to traffic and maintain connections between services. It is designed to be portable and uses a platform-agnostic core architecture as its foundation.

Can NGINX be used with AWS?

Yes, NGINX can be used with AWS. NGINX is a popular open source web server that can be used with many cloud providers, including AWS. NGINX is highly scalable, making it ideal for hosting and managing web applications in the cloud.
