Can Jira Server integrate multiple CI/CD tool sets?

[Adrian]

We serve different clients who all have different CI/CD tools. 

I want to learn whether Jira can handle running multiple integrations of different CI/CD tools by Jira project eg where we might use AWS tools to commit to repositories and deployment for one customer and Azure for another, etc. all within the same one instance of Jira Cloud. 

If not how do other companies handle this?
