Envoy vs Traefik vs Vulcand: What are the differences?

Introduction

Envoy, Traefik, and Vulcand are all popular and powerful proxy servers used for load balancing and routing traffic in modern applications. While they serve the same purpose, there are key differences between them. Let's delve into the key differences between Envoy, Traefik, and Vulcand.

  1. Performance and Scalability: Among the three, Envoy is known for its exceptional performance and scalability. It is designed to handle high traffic loads efficiently, utilizing a low memory footprint and supporting multi-threading. Traefik, on the other hand, is also performant but may not match the high scalability levels of Envoy. Vulcand, while capable, may fall behind in terms of performance and scalability compared to both Envoy and Traefik.

  2. Protocol Support: When it comes to protocol support, Envoy offers a comprehensive range of protocols, including HTTP/1.1, HTTP/2, gRPC, and more. This broad protocol support allows Envoy to handle diverse types of traffic effectively. Traefik also provides robust protocol support, including HTTP, TCP, UDP, and WebSocket, but may have some limitations compared to Envoy. Vulcand, while supporting HTTP and TCP protocols, may not match the extensive protocol support provided by both Envoy and Traefik.

  3. Configuration Flexibility: Envoy provides a flexible and extensive configuration model, allowing fine-grained control over load balancing and routing rules. It supports declarative configuration and allows for dynamic updates without restarting the proxy. Traefik also offers flexible configuration options, including support for dynamic configuration updates. Vulcand, although providing some configuration flexibility, may have more limited options compared to both Envoy and Traefik.

  4. Service Discovery Integration: Envoy integrates well with various service discovery tools, such as Consul and etcd, enabling automatic discovery and configuration of backend services. Traefik also offers rich integration with service discovery mechanisms, including Docker, Kubernetes, and Mesos. Vulcand, while supporting service discovery integration, may have fewer options and integrations available compared to both Envoy and Traefik.

  5. Load Balancing Algorithms: Envoy provides a variety of load balancing algorithms, including round robin, least connections, random, and more. These algorithms allow for fine-tuning and optimizing traffic distribution. Traefik also offers multiple load balancing algorithms, including round robin, IP Hash, and least connection. Vulcand provides load balancing capabilities, but the range of algorithms may be more limited compared to both Envoy and Traefik.

  6. Community and Support: Envoy has a large and vibrant community, backed by the Cloud Native Computing Foundation (CNCF), ensuring continuous development, frequent updates, and extensive community support. Traefik also has a strong community and is backed by a dedicated development team. Vulcand, while having community support, may not have the same level of community engagement as both Envoy and Traefik.

In summary, Envoy stands out in terms of performance, scalability, and protocol support, offering extensive configuration flexibility, while Traefik provides good performance, protocol support, and dynamic configuration options. Vulcand, although capable, may have limitations in terms of performance, protocol support, and community support.

        What is Envoy?

        Originally built at Lyft, Envoy is a high performance C++ distributed proxy designed for single services and applications, as well as a communication bus and “universal data plane” designed for large microservice “service mesh” architectures.

        What is Traefik?

        A modern HTTP reverse proxy and load balancer that makes deploying microservices easy. Traefik integrates with your existing infrastructure components and configures itself automatically and dynamically.

        What is Vulcand?

        Vulcand is a programmatic extendable proxy for microservices and API management. It is inspired by Hystrix and powers Mailgun microservices infrastructure.

        What are some alternatives to Envoy, Traefik, and Vulcand?
        Istio
        Istio is an open platform for providing a uniform way to integrate microservices, manage traffic flow across microservices, enforce policies and aggregate telemetry data. Istio's control plane provides an abstraction layer over the underlying cluster management platform, such as Kubernetes, Mesos, etc.
        NGINX
        nginx [engine x] is an HTTP and reverse proxy server, as well as a mail proxy server, written by Igor Sysoev. According to Netcraft nginx served or proxied 30.46% of the top million busiest sites in Jan 2018.
        linkerd
        linkerd is an out-of-process network stack for microservices. It functions as a transparent RPC proxy, handling everything needed to make inter-service RPC safe and sane--including load-balancing, service discovery, instrumentation, and routing.
        Trailblazer
        Trailblazer is a thin layer on top of Rails. It gently enforces encapsulation, an intuitive code structure and gives you an object-oriented architecture. In a nutshell: Trailblazer makes you write logicless models that purely act as data objects, don't contain callbacks, nested attributes, validations or domain logic. It removes bulky controllers and strong_parameters by supplying additional layers to hold that code and completely replaces helpers.
        HAProxy
        HAProxy (High Availability Proxy) is a free, very fast and reliable solution offering high availability, load balancing, and proxying for TCP and HTTP-based applications.
