Two new dyno types, Private-S and Private-L, available inside Heroku Private Spaces
Change effective on 26 February 2016
These two new types, private-s and private-l dynos, will complement the existing private-m dyno type available in Private Spaces. Private-s dyno types will be a great fit for smaller workloads, and private-l dynos will be a great fit for larger workloads.
See here for complete description and pricing of these and other dynos available in Heroku Enterprise.
