Serverless

Kubernetes vs serverless vs virtual machines is the infrastructure argument that eats the most meeting time and produces the least clarity. All three models will run your application, so the decision is really about the size of your team, the shape of your traffic and the software you already own. This guide compares the three on the things that actually move the answer: what each model is and who owns what, how the bill is genuinely built, the operational hours nobody budgets for, the crossover point where serverless stops being cheaper, realistic migration paths, and a weighted scoring framework you can complete with your own numbers.
