I can't see the difference between a "solution provider" that hosts your Jira and just getting Atlassian to do it. What's stopping the solution provider from accidentally running a script that deletes some customer's files and struggling to do a partial backup restore?
Because you can get the best parts of self-hosted and managed services. And on that backup question: self-hosted Atlassian is vastly easier to protect against disasters. The problem these Atlassian guys had arose from multi-tenant architecture. Usually managed service providers will host your stack on individual databases and VMs, and backing up the software is just a matter of taking pg_dumps and rsyncing certain directories (pretty old school) or just taking disk level snapshots.
Many medium-large corporations have their own cloud environments that their IT Ops control. Solution providers can host Atlassian stacks on their own cloud environment where they are not affected by data privacy concerns (it's in their already green-lit cloud providers data center) so they can host it behind a firewall with only VPN access allowed. They can also do all the magic you can usually do with web software like put a frontend proxy in front of it, or use more flexible/legacy authentication methods. Not to mention that for example you could have a Jira Cloud that you would need to integrate with a SCM program. Jira data could be "OK" to live in the cloud but code would be a big no-no. These problems can be solved by having them all live behind the firewall.
A competent managed solution provider also has consultants that can train or instruct on usage. It costs but it is simpler and faster than having to go through the forums or send a support ticket for every small issue to Atlassian itself.
Correct. There are probably not a lot of MSPs that have so many customers that they need to share that much data, and their customers probably use MSPs for the strict purpose that they don't want to share things with other companies.
