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: Dropbox the free Basic plan gives 2 GB of storage; 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.
  • They diverge on capability: Dropbox covers File synchronization, Envoy covers xDS dynamic configuration.
  • Prices and features above were last checked on 30 August 2026.

Envoy

  • Acting as the data plane under a service mesh or Gateway API implementation, which is how the overwhelming majority of deployments use itnot Dropbox
  • An edge or API gateway that needs per-route retry budgets, circuit breaking and outlier detection rather than round-robin proxyingnot Dropbox
  • Migrating traffic between service versions or between a monolith and its replacement, using weighted splits and shadow trafficnot Dropbox
  • 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 Dropbox

Where each one falls short

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

Dropbox

  • The free Basic plan gives 2 GB of storage
  • Version history is 30 days on Plus, 180 days on Standard and 1 year on Advanced
  • File transfers are capped at 50 GB on Plus and 100 GB on the team plans
  • The Advanced team plan requires a minimum of 3 users at $24 per user per month
  • eSignature requests are limited to 3 per month on Plus and Standard

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.

Answered from the vendors’ own pages

Dropbox: How much does Dropbox cost?

Dropbox offers a free 2GB plan. Plus is $9.99/month (2TB), Standard is $15/user/month (3TB team), and Advanced is $24/user/month (15TB team).

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.

Dropbox: Is Dropbox free?

Yes, Dropbox Basic is free with 2GB of storage for personal use and file sharing.

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.

Dropbox: What is the difference between Dropbox Plus, Standard, and Advanced?

Plus at $9.99/month offers 2TB personal storage. Standard at $15/user/month offers 3TB for teams with 180-day recovery. Advanced at $24/user/month offers 15TB with 1-year recovery and single sign-on.

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.

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.
