Large companies in some legacy industries have remained resistant to the relentless march of cloud technology. Fear of failure in the data migration process, data governance concerns, and the overwhelming scope of the undertaking mean that many big companies are not even contemplating moving to the cloud.

The big three public cloud providers - Amazon, Microsoft, and Google - have decided that if legacy businesses won't come to the cloud, then the cloud will come to them. 

All three providers have launched propositions focused on companies still running their own data centres. Rather than asking them to move to Azure, Microsoft is selling software to companies that allows them to manage their own data centres more efficiently. 

Google and Amazon both offer services that allow companies to move computing loads between their own private data centres and remote, public locations on demand.

The vast majority of insurers have not made the move to the cloud, but these new offerings could take them a step closer.
