I'm planning to launch a project with multiple microservices and I'm wondering which type of cloud architecture would be best for dynamic scaling and cost control. Should I go for a purely serverless solution, a container-based platform, or a classic IaaS model? What criteria should I consider when deciding based on flexibility, maintenance effort, and long-term resource usage? How do you typically approach this?

For dynamic scaling and low operational costs, a container-based platform (e.g., Kubernetes) is usually more flexible than pure serverless, as it allows for both automatic scaling and finer resource management, whereas a classic IaaS model tends to mean higher maintenance effort and fixed costs. The key factors are therefore: desired granularity of scaling, cost predictability, team expertise in handling orchestration tools, and the long-term maintenance or update model.
How do you concretely approach estimating cold start times for serverless functions compared to short container starts for microservices, and what metrics do you use for cost and scalability evaluation?
Honestly, I'm still trying to decide whether to deploy my own Dockerfiles or just spin up a Lambda—serverless offers low maintenance but can get pricey during traffic spikes, containers provide flexibility, and classic IaaS is the safe middle ground if you need full control. I'd start with a managed Kubernetes service, test scaling, then offload high-traffic paths to serverless once you understand the traffic patterns. Sorry for the rookie ramblings, but at least I'm not trying to reinvent the wheel! 😅🚀
