AWS Developer Associate Readiness: Build Serverless and Container Apps on AWS

A coach that teaches by asking — not by lecturing

The Lighthouse Coach is an AI Socratic coach built on Cognosco Learning's AWS Developer Associate Readiness: Build Serverless and Container Apps on AWS course, in the Personal Effectiveness & Well-Being category. It does not play videos at you. It holds a conversation: it asks you a question, listens to your answer, names the misconception it hears, affirms what you got right, and asks the next question — the way a great coach works in the room.

Readiness, honestly judged — never a guaranteed result. This course promises readiness, never a pass. It teaches to the published AWS Certified Developer — Associate (DVA) skills outline at the level that outline is published — the task statements and the services they name — and it flags that outline as a document Amazon Web Services revises, which you must verify in its current form before you book. No page claims to know actual exam questions, and no score in this course guarantees an outcome in a testing center. What the capstones certify is the narrower, more useful thing a course honestly can: that you have worked every concept on fresh problems, defended each decision from a deciding fact, and learned to judge your own readiness from evidence.

It starts with the deciding fact. Meet Kinvara Field Services, the running company whose booking application this course builds, ships, and debugs end to end. Almost every hard question — on paper or in production — presents a small situation and four plausible moves, of which one is governed by a fact the situation quietly contains: a timeout, a key, a trigger, a permission, a bill. The skill is not recognizing service names. The skill is finding the deciding fact and letting it choose the move — name it first, in writing, before you name a service.

It works in two movements. First, Module 1 — Build and Connect: The Developer Seat on AWS — work through Concepts 1–9, finishing with The Booking Feature, Built Whole; then, Module 2 — Ship, Secure, and Observe — work through Concepts 10–18, finishing with Ship the Release, Then Prove It in Production.

Both capstones produce real artifacts — a build plan for Kinvara's first customer-facing feature, complete enough that another developer could build from it and a reviewer could examine it: the invocations mapped, the data designed from its access patterns, the door disciplined, the identities least-privilege, and the failure paths confessed in advance; and a ship-and-observe plan for taking that feature to production — the release design, the identity and data-protection decisions, and the debugging method, written completely enough that an on-call developer who has never met you could run the release and work its first incident from your document alone.

The honesty standard is part of the course. This is the developer's seat on AWS, and only that seat. No. 242, AWS Cloud Practitioner, is entry-level orientation, and this course assumes it — or equivalent experience — without repeating it. No. 340, AWS Solutions Architect in Practice, designs whole systems from the architect's seat; this course does not sit in that seat either. The developer's questions are narrower and, in their own way, harder: I have code — how does it run, what invokes it, what does it read and write, how do I ship a new version safely, how do I know what it did at 2 a.m., and how do I prove all of that under exam conditions? And because cloud platforms change their consoles, tools, and defaults constantly, the course teaches at workflow level only — the durable pattern that survives a console redesign.

The course is self-paced and always on — roughly 30 minutes per concept, about 9 hours in full, taken in as many sittings as you like. You can type your answers, or talk out loud: the Voice Coach speaks its questions and listens to your spoken replies. Learners who already know the material can test out concept by concept.

AWS Developer Associate Readiness: Build Serverless and Container Apps on AWS is part of The Lighthouse Signature Series — the online counterpart to the one-day, in-person learning Cognosco Learning has delivered since 2002.
