Between serverless computing and hosting a backend on a server, serverless computing is generally cheaper to maintain as it eliminates the need to manage servers and infrastructure. The cloud provider handles all of the server maintenance, security updates, and scaling. However, the costs would depend on the specific usage requirements and traffic volume of your digital marketplace.
For a digital marketplace, serverless computing could be a good option as it offers built-in scalability to handle changes in traffic, and it requires minimal technical expertise to get started. However, if your marketplace has complex requirements or needs a high level of customization, hosting on a server may offer more flexibility. It really depends on your technical skills and how much control you need over the infrastructure.
Without more context on the specific requirements of your digital marketplace, I can't definitively say which approach would be best. But based on what you've described, I would recommend evaluating serverless computing as a potentially affordable and easy to maintain option, as long as it meets your performance, security, and customization needs. If you have more details on the requirements of your marketplace, feel free to provide them and I can provide a more tailored recommendation.
