best practices for parameter store

Hi, we are just starting to use many docker containers, which we need to pass secure parameters. We took a look to 2 options, parameters store and secrets manager. Looks like parameters store adjust better to our requirements.

Question is, while setting the value of the parameter, I noticed it’s possible to store a json string. We have 6 microservices, each uses many parameters (let’s say 10 parameters per microservice, so 60 parameters in total).

What would be better, to create 1 parameter in parameter store, and store all parameters as json for 1 service (i.e. 6 parameters created) and parse the json, or to create every parameter separately resulting in 60 parameters?
