Hi Mehmet, thanks for your question!
Yes, Atlassian Government Cloud (AGC) will include Forge Apps (including the ones using Forge hosted storage). That is, Forge Apps will be available to AGC customers. However Forge Apps that already exist in Atlassian Marketplace won’t be available to AGC customers automatically. This will require Forge App owners to deploy their apps into AGC. We call this making Forge Apps AGC “compatible”.
Note that, this is different from making Forge Apps FedRAMP “compliant”. Marketplace Partners are not enforced go through FedRAMP authorization process for their apps. AGC customers will be able to use non-compliant Forge Apps at their discretion, provided the apps are compatible.
We’ll soon share a more detailed update with our Marketplace Partners containing guidance on how they can make their apps AGC compatible. So please stay tuned for more detailed instructions and in the mean time let us know if you have further questions.
