> I am not sure why is the default option is NO There is no deep meaning here. Just to confirm if user has read the prompt. If user press enter without reading then it will not install as default option is `No` >What is Gluu Gateway database mode It means Gluu Gateway will user PostgreSQL as its database. In DB-less mode, it will use declarative config file (kong.yml) for storage. >why DB-less mode is recommended @Mohammad.Abudayyeh could you reply this question

DBless mode is the production mode as it uses declarative configuration using `kong.yml` instead of the UI. Database mode adds another layer which is the database that needs to be maintainable , highly scalable and highly available. It is a little harder to get use to the DBless mode but in terms of cloud native application it scales better and preforms faster. You save the operation and engineering cost of having an extra database.
