Envoy

Technology

A high-performance L7 proxy written in C++ that is configured by an API rather than a config file, and is usually deployed under a control plane.

The short version

  • Each has a real cost: CloudAMQP free tier messaging limits are low: 1-2M messages/month; Envoy the configuration surface is very large and hand-written bootstrap YAML runs to hundreds of lines for routing that Nginx expresses in twenty, which is why nearly every production deployment sits under a control plane and inherits that control plane's constraints as well.

Envoy

  • Acting as the data plane under a service mesh or Gateway API implementation, which is how the overwhelming majority of deployments use itnot CloudAMQP
  • An edge or API gateway that needs per-route retry budgets, circuit breaking and outlier detection rather than round-robin proxyingnot CloudAMQP
  • Migrating traffic between service versions or between a monolith and its replacement, using weighted splits and shadow trafficnot CloudAMQP
  • Standardising observability across a polyglot estate, so that latency, error rates and tracing look the same regardless of the language a service is written innot CloudAMQP

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

CloudAMQP

  • Free tier messaging limits are low: 1-2M messages/month
  • Free tier connection limits are restrictive: 20-40
  • Multi-tenant plans have queue limits (200-2,000 max)
  • Dedicated plans expensive at scale: up to $14,995-$17,495/month
  • Extra disk space add-on at $0.35/month per GB may add significant cost

Envoy

  • The configuration surface is very large and hand-written bootstrap YAML runs to hundreds of lines for routing that Nginx expresses in twenty, which is why nearly every production deployment sits under a control plane and inherits that control plane's constraints as well.
  • xDS is the real API and it is not stable in the comfortable sense; the v2 API set was removed outright, resource types continue to be deprecated, and your control plane and Envoy binaries have to be upgraded roughly in step or the proxies stop accepting configuration.
  • Extending it properly means writing a C++ filter and building and maintaining your own Envoy binary; the alternatives are Lua, which adds per-request overhead, and proxy-wasm, whose ABI has remained effectively experimental for years with a real performance cost.
  • At sidecar density the per-proxy memory and CPU footprint is a measurable share of cluster capacity, since thousands of workloads each carry a full proxy, and this is precisely the cost that has pushed mesh projects towards node-level or ambient architectures.
  • There is no single vendor selling support for Envoy itself; you get the community plus control-plane vendors such as Solo.io and Tetrate, so an Envoy-level production bug is your own engineers in a C++ codebase unless a support contract happens to cover it.
  • Diagnosing why a request got a particular response involves reading config dumps, the stats endpoint and the RESPONSE_FLAGS codes in access logs rather than a readable error, which is a specific skill you must hire or spend months growing.

Questions people ask

Is CloudAMQP or Envoy better?
Neither clearly leads. CloudAMQP starts at Free and Envoy at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, CloudAMQP or Envoy?
CloudAMQP starts at Free and Envoy at Free.
Does CloudAMQP or Envoy run on more platforms?
Both run on Web, so platform support will not decide this one for you.
Can I use CloudAMQP for free?
Both have a free tier, so you can try either at no cost before committing.
What is CloudAMQP best used for?
CloudAMQP is most often used for message queue services, message brokers for distributed systems, rabbitmq and lavinmq hosting, asynchronous task processing. Of those, message queue services and message brokers for distributed systems are not what Envoy is typically brought in for.
What can CloudAMQP do that Envoy cannot?
Envoy covers xDS dynamic configuration, Protocol breadth, Filter chain architecture, Observability by default.

Answered from the vendors’ own pages

CloudAMQP: Does CloudAMQP offer free plans?

Yes, CloudAMQP offers free tiers: LavinMQ Loyal Lemming with 2M messages/month, and RabbitMQ Little Lemur with 1M messages/month. Both include connection and queue limits.

Source
Envoy: Should I run Envoy on its own, or under a control plane?

Almost always under one. Directly authoring xDS or static bootstrap configuration is viable for a handful of routes and becomes unmanageable beyond that. Envoy Gateway, Istio, Contour, Gloo and Consul all exist to generate that configuration for you.

CloudAMQP: What is the cheapest paid plan?

Both LavinMQ Elegant Ermine and RabbitMQ Tough Tiger cost $19/month. LavinMQ includes 20M messages/month with 200 connections; RabbitMQ includes 10M messages/month with 100 connections.

Source
Envoy: How does it compare with Nginx or HAProxy?

Envoy is dynamically configured over an API and instrumented far more heavily; Nginx and HAProxy are faster to configure and lighter for straightforward reverse proxying. If you never need to change routing without a reload, Envoy is more machinery than the problem requires.

CloudAMQP: How are messages charged on CloudAMQP?

CloudAMQP plans include monthly message quotas. All plans are charged on a per-second basis with monthly billing cycles.

Source
Envoy: What does it cost?

Nothing to licence; it is Apache 2.0 and there is no paid edition. The cost is engineering time and, for most organisations, a commercial control plane or cloud service that packages it.

CloudAMQP: What add-ons are available?

CloudAMQP offers Virtual Private Cloud add-on at $99/month, and extra disk space at $0.35/month per GB (25-2,000 GB available).

Source
Envoy: Can I write extensions without C++?

You can write Lua filters or proxy-wasm modules in Rust, Go, C++ or AssemblyScript. Both carry per-request overhead compared with a native filter, and the Wasm path has been slower to stabilise than the project originally projected.

Envoy: Is it a CNCF project?

Yes, it is a graduated CNCF project licensed under Apache 2.0, which means the trademark and governance sit with the foundation rather than with Lyft or any vendor.
