Enterprise Cloud For Dummies, Nutanix Special Edition
public cloud providers had to contend with a number of
daunting challenges:
✓ Bandwidth: There was — and in many cases, still is —
concern around how certain areas of the world are
served with Internet bandwidth. Many locales remain
woefully underserved, making it difficult to deploy
mission‐critical services to an environment that relies
on an Internet connection. Although this issue is being
corrected, improvement is coming slowly. In addition,
many places that have decent bandwidth still have only
a single connection, which makes cloud somewhat unpalatable. That said, the situation today is far better than it
was just ten years ago.
✓ Loss of control: At the beginning, the public cloud was
an island. You had to manage it with completely separate tools, and a wall stood between it and your local
datacenter environment. Today, a plethora of tools exist
to help organizations seamlessly manage both local
datacenters — private clouds in some cases — and
public cloud environments. Control is no longer an issue.
✓ Skills: When any new technology hits the streets, building up adequate skills to support it takes time. Today,
with years of experience under their belts, plenty of
people with the necessary skills are available to maintain
public cloud infrastructure and services.

Understanding security
and trust in the cloud
Because security is so important, it gets its own section rather
than being relegated to a bulleted list! With regard to security,
the public cloud has made massive strides in the past decade.
Security in the cloud is orders of magnitude better than it was
in the early days. In fact, many providers make available hardened environments so that they can properly secure sensitive
workloads for their customers.
People’s willingness to trust the cloud is evidenced by the
massive growth of clouds of all types. Microsoft continues to
report that growth of Office 365 — Software‐as‐a‐Service —
continues to explode, and Amazon is reporting record growth
with Amazon Web Services.
