The Open buttons send the prompt text as currently shown below to that site only when you click. Fill in the placeholders first.

Help me decide between serverless functions, containers on a managed platform, and virtual machines for a workload. Workload description (traffic pattern, latency needs, runtime duration): [WORKLOAD]. Team skills: [TEAM_SKILLS]. Budget and cost sensitivity: [BUDGET]. Compliance or data residency requirements: [CONSTRAINTS].

Create a weighted decision matrix with criteria I can edit: cost at low and high load, cold-start sensitivity, operational burden, portability, debugging, scaling limits, and security responsibility. Fill in the scores with reasons tied to my facts. Calculate the total cost of two traffic scenarios using formulas and placeholders for prices that I fill in from current provider pricing. Provide a recommendation with the conditions under which it would flip, and a small proof-of-concept plan for a one-week trial.

Add a section that lists the assumptions that most affect the result, and how the recommendation changes if each is wrong by a factor of two. Provide a short test plan with measurable acceptance criteria (latency percentile, cost per thousand requests, deployment time) for the trial, and a note on lock-in with an estimated exit effort in person-days.
