dont know when to go serverless or containers for microservices? its a common question. lets break it down.

hey everyone im tryin to decide on the best compute strategy for a new set of microservices. we're leanin towards microservices for agility, but the deployment is the big question. serverless (like aws lambda) seems great for auto-scaling and cost efficiency for spiky workloads. but containers (like docker/kubernetes) offer more control, predictable performance, and easier local development and testing. for a system that will have some steady traffic but also unpredictable spikes, when do you all find yourselves choosin one over the other? whats the key decision points you look at
