@Ralph Mul Thanks for reaching out. 4 GB physical memory and 2 CPU cores is a good starting point for a Linux VM that is hosting a self-hosted API gateway in a Docker environment. However, it's important to note that the actual resource requirements may vary depending on the specific workload and usage patterns of the API gateway.
We expect customers to monitor their performance and physical resources and adjust as needed
do let me know incase of further queries, I would be happy to assist you.
