Gloo vs others

Gloo is an API Gateway and may come up in discussions about how it’s different from “X”. Although API Gateways are not new, API Gateways have been going through an identity crisis recently in terms of deployment footprint, use cases, and their renaissance in cloud-native architectures vis-a-vis service mesh. We go into a lot of detail in this blog, but to put it concise, the categories of API Gateways fall loosely into the following:

vs API Management

Gloo can be compared to traditional API Management vendors but is significantly simpler and more powerful. Gloo doesn’t require complicated databases, outdated proxies, and high-friction configuration in terms of reams of XML or bespoke, complex APIs etc. Gloo can act as an edge/external API management platform for external APIs.

Simple reverse proxies

There are excellent reverse proxies out there for moving bytes from one connection to another, but Gloo – as it’s built on Envoy – provides a lot more features like powerful traffic matching, routing, and loadbalancing, circuit breaking, distributed tracing, deep telemetry collection and more. In today’s cloud-native environment, these features are not nice to haves – they’re table stakes.

Integration products

Legacy integration products have been cloud-washed to provide some of the functionality of an API Gateway, but they’re typically full of baggage, don’t scale, and are not easily configured for use in dynamic cloud environments. Gloo is purpose built for these environments and for these cloud-native API gateway problems.

Software frameworks

Building an API Gateway for a simple use case is possible using generic software libraries and frameworks, but will it be battle tested? Will it be flexible enough? When you get past your simple use case, will you afford it the attention it needs? Building a capable gateway is easy for simple use cases, but once you need features that are standard with Gloo, it will be a lot of undifferentiated heavy lifting to get your bespoke proxy up to par with industry standards.

Other Envoy products

Some other vendors have also chosen Envoy as their data-plane proxy and there will be many more emerging in the near future. Choose Gloo for these reasons:
