 As the number of microservices and annotations proliferate, running `kubectl describe` can get tedious. Moreover, using `kubectl describe` requires every developer to have some direct access to the Kubernetes cluster. Over the past few years, [service catalogs](https://www.getambassador.io/learn/kubernetes-glossary/service-catalog) have gained greater visibility in the Kubernetes ecosystem. Popularized by tools such as [Shopify's ServicesDB](https://shopify.engineering/scaling-mobile-development-by-treating-apps-as-services) and [Spotify's System Z](https://dzone.com/articles/modeling-microservices-at-spotify-with-petter-mari), service catalogs are internally-facing developer portals that present critical information about microservices. Note that these service catalogs should not be confused with the [Kubernetes Service Catalog project](https://svc-cat.io/). Built on the Open Service Broker API, the Kubernetes Service Catalog enables Kubernetes operators to plug in different services (e.g., databases) to their cluster.
 
-Historically, service catalogs have not been a key piece of infrastructure, as applications consisted of a single monolith. Today, with distributed development and microservices the norm, service catalogs are increasingly being adopted as a best practice. Some popular options today include [Backstage]((https://backstage.io/) and [Ambassador Service Catalog](https://www.getambassador.io/products/service-catalog). Backstage is a highly flexible project ideal for organizations that wish to customize every aspect of their service catalog, while Ambassador Service Catalog provides a turnkey, cloud-hosted solution that can be set up quickly.

 ## Annotate your services now and thank yourself later
 Much like implementing observability within microservice systems, you often don’t realize that you need human service discovery until it’s too late. Don't wait until something is on fire in production to start wishing you had implemented better metrics and also documented how to get in touch with the part of your organization that looks after it.
