Amazon CodeCommit — хороший, хотя и не идеальный Git.

На Windows подключить можно как по SSH, так и по HTTP.

Рассмотрим вариант с HTTP:

2. Install Source Tree: https://www.sourcetreeapp.com/
3. Install AWS CLI: http://docs.aws.amazon.com/cli/latest/userguide/installing.html#install-msi-on-windows
4. Download & install AWS SDK for .NET: http://sdk-for-net.amazonwebservices.com/latest/AWSToolsAndSDKForNet.msi
5. Run PowerShell as Administrator
6. Check Git: git —version
7. Check AWS CLI: aws —version

9. Enter AWS Access Key ID & AWS Secret Access Key. Stay Default region name & Default output format blank.
10. Execute: Set-Location ‘C:\Program Files (x86)\AWS Tools\CodeCommit’

12. Add repo to Source Tree & clone it.
