 1. Scaling (only if needed) depending on trace-server scaling accordingly.
 1. Without scaling, deploying GraphQL Server using containers may still help.
 
+#### Apollo Server trial
+
+1. Apollo's [Getting-started][svr-start] steps were tried once, locally, while preparing this ADR.
+1. Those steps simply show how a GraphQL query may request data based on a schema (`index.js`).
+1. For server to know how to provide that data, a `resolver` function was part of `index.js`, then.
+1. [Apollo][svr-start] is [OSS][svr-open], with [***optional*** commercial add-ons][svr-opt].
+   * It is [a TypeScript server based on Node.js][svr-open].
+   * It has [built-in][svr-rest], [REST](#GraphQL-for-TSP-API-(over-REST)) resolver data support.
+   * Should that support not fit TSP's endpoints, [tsp-typescript-client][client-ts] could be used.
+1. Server doesn't require Kubernetes or a container-based deployment, which then remains optional.
+1. Server doesn't require using the [potentially licensed Apollo Studio][svr-opt] either.
+
+#### Apollo Client: optional
+
+* [Apollo Client][svr-client] seems to be mainly [open-source][svr-client-open] too.
+* It is mostly intended as [a caching aid][svr-client-caching]; to be referred to, maybe, later on.
+* It is [based on React][svr-client], but [other integrations are listed][svr-client-open].
+* This ADR doesn't require a deeper analysis yet, given TSP's current clients to integrate first.
