When you run your software on premise, you are resonsible for all aspects of your system.
Backups, upgrades, patching etc.
With SaaS and hosting providers, you move some of this responsibility to the provider.
However, you also enter into a complex 'supply chain'
You are paying the SaaS provider, who in turn pays a hosting company who in turn might be reselling services from one of the larger providers.
What happens if any of these companies get into financual difficulty?
For example the SaaS provider has not paid their bill, or the server hosting company is not meeting its finance agreements.
Your data sits on a server that you do not own and you are probaly not part of the agreement in dispute.
What steps can you take to protect yourself from this problem?
I am sure it is a question that some of the SaaS providers have had to address.
