What s the principal difference between MS AppCenter and Azure DevOps former VSTS

Question

I have used them separately but I want to know the core differences what particular tasks are to be done by them and so on. Is it just one of the modern "marketing" features of Microsoft, when there is mostly no difference, but those are just two similar things wrapped with a different-colored envelope?

Answer 1

I think we need both app center and DevOps from a project perspective. DevOps to develop and deploy, and App Center to deploy and monitor.
If you are comfortable using multiple tools for your project then the app center is enough there is no need for DevOps. I prefer App Center as I  can have all the features of bitbucket and Jira, along with an easier test & deployment setup and monitoring.
I hope this helps you.
