Commentary: Enterprises try their best to secure their data, but running on-premises mail servers arguably doesn't do this.
We can have a debate about how soon enterprises should embrace cloud.
Can we agree that for some use cases, there's no compelling reason for organizations to keep running their own servers? In the wake of a hack that exposed the Microsoft Exchange servers of tens of thousands of U.S. organizations, email servers probably belong on that list.
Nor are they helped by legacy vendors, said CTO Paul Johnston: "The cloud ecosystem is big but there are many many companies still selling the old stuff." Enterprises have relationships with these existing vendors.
Companies still worry about security, governance and more in the cloud.
For some things, which seems to include mail servers, it's arguably better to run them in the cloud.
