You can easily share Trello boards with another person.
Box 2: Azure Pipelines –
You can use Bamboo to implement CI/CD (Continuous Integration and Continuous Delivery) for a simple Azure function app using Atlassian Bamboo. Bamboo does continuous delivery of the project from source code to deployment. It has stages including Build, Test and Deploy.
Software teams in every industry are upgrading their continuous delivery pipeline with Bamboo. Easy build import from popular open source tools, user and group import from JIRA, seamless integration with Bitbucket, and native support for Git, Hg, and SVN means you’ll be building and deploying like a champ.
Box 3: GitHub repositories –
Bitbucket can be used as the Git repository, but you can use any other Git repository (Like TFS Git) for source control of the code.
