Ops wants a lightweight sidecar-style agent to ship enhanced telemetry from many Lambdas without rewriting business handlers each time. Which Lambda feature fits?
Select an answer to reveal the explanation.
Short Explanation
Picture a quiet sidecar that rides with every delivery truck without rewriting the cargo checklist. Lambda extensions host that cross-cutting telemetry agent outside the business handler. Pasting HTTP clients into every function, gutting handlers for Map states, or silencing logs miss the extension model.
Full Explanation
Lambda extensions provide a mechanism for companion processes that handle cross-cutting concerns such as telemetry or secrets fetching without modifying each business handler. Duplicating clients in every function increases maintenance. Replacing handlers with unrelated Step Functions patterns or disabling logs does not deliver a reusable sidecar-style agent.
