If you ask many companies they may not think about their data being multi-cloud. The thinking is more about their application estate.
On pressing you will be told that they may have windows filers, have a NAS or SAN, perhaps are using object storage either on-premises or on-cloud with something like Amazon S3, use email, perhaps outsourced to someone like Google, which also provide their employees with a cloud drive, are using a cloud based CRM such as Salesforce and perhaps a raft of other cloud based Apps that have file storing capabilities.
Congratulations, that is what a multi-cloud data company looks like in 2019 !
An interesting chat with David Horrigan from the 451 Research Group confirmed what I had suspected for a while, that for most companies, large and small, Information Governance, as an IT initiative it still does not feature very highly on their agenda.
Although information governance is a pre-requisite for certain industry vertical such as legal and medical, companies tend to try and solve specific point issues rather than implementing an information governance framework. Examples of these are Bring Your Own Device (BYOD) or Mobile Device Management (MDM) policies that whilst in some cases needed, is only one example of the disciplines around information that is required.
