Elasticsearch Platinum license

I am planning to buy an elasticsearch platinum license. We have three working environments, Dev, Uat, Prod.
If I buy one elasticsearch platinum license, is it enough to use the same license on three environments or should we buy three individual liceses for three environments.?
