TeamCity Cloud is available as an Annual Subscription License, to continue to use it after 1 year, you need to renew the license. For annual Subscriptions - your Subscription Period ends on the last day of the previous calendar month in the following year.
TeamCity Cloud subscription levels are predominantly based on the number of committers, users who make changes in the project code. All users who author 10 or more VCS changes over a 30-day period require a committer slot in TeamCity Cloud.
Note that only contributors to the source code take the committer slots. An unlimited number of non-committing users (managers, QA, and so on) can get access to the TeamCity web interface.
Committer
A user who authors VCS (version control system) changes for projects that are built by TeamCity. A user occupies a committer slot after committing 10 or more changes into your projects during 30 days. This slot is reserved for this user until their last 10th commit gets older than 30 days. For example, if a user makes 5 commits on June 10 plus 5 commits on June 11 and then stops committing, TeamCity will release their committer slot on July 10, after 30 days since the first of these last 10 commits.
Build credits (8,000 per Committer)
Build credits in TeamCity Cloud can be redeemed for build minutes on JetBrains-hosted agents or exchanged at a flat rate for concurrent builds on self-hosted agents. You can also exchange build credits for additional storage, data transfer, and committer slots. Build credits are granted per every committer slot in a subscription.
Cloud storage (40 GB per Committer)
Provided for storing the results of builds, primarily build artifacts and build logs.
Cloud data transfer (200 GB per Committer)
Cloud data transfer is counted when you download artifacts and build logs from TeamCity Cloud to outside locations. For example, to self-hosted agents, via the TeamCity web UI, or using tools like wget or curl.
