Enterprise Cloud For Dummies, Nutanix Special Edition
In addition, economies of scale stop providers from offering a
more differentiated experience for individual customers and
applications. One of the biggest roadblocks to public cloud
adoption is that customers want control over where the data
sits and how it is accessed. This level of control is not always
possible with the public cloud.
With public cloud, customers may not always know exactly
where their data resides. Is it in their state or even in their
country? With a patchwork of data security and privacy laws
worldwide, not knowing where data resides can create compliance and security issues for customers. Some organizations
desire all sensitive data to be under their direct control, effectively eliminating public cloud as a locale.
However, with the private cloud, data locality and proximity are 100 percent in your control. You get to decide exactly
where data resides and how close it sits to end-users and
applications.

Linking custom‐tailored SLAs and
performance characteristics
Although public cloud providers have become far more adept
at offering granular service level agreements (SLAs), nothing
compares to what you achieve with your own infrastructure.
When you’re considering SLAs, be sure to consider these two
points:
✓ Availability: Uptime is critical. Innumerable statistics
show that the hourly cost of downtime can be insanely
expensive when you consider lost business, lost
employee productivity, overtime for IT to bring services
back into operation, and public relations costs.
✓ Performance: Poor infrastructure performance can
plague your financials just as much as downtime. As
employees struggle to get their work done and as customers struggle to do business with you — and eventually give up — performance issues can be a huge drain on
the coffers.
