Public Cloud

What is a Public Cloud?

“The public cloud is a multi-tenant architecture where data is shared through the same infrastructure using the same hardware resources. Public cloud is often used when services are provided for free or pay-per-usage over public networks.”

So the heck does that mean?

The “public cloud” is public because you are sharing the same pool of resources with other firms and people.

Lets use an example from housing (because everyone lives somewhere right?)

  • If you live in a apartment building, you share hallways, you share a lawn, you may share electricity bills, etc.
    • You are a tenant.
  • If you own a home, you have full control of those shared resources.
    • The building is “privately owned”, [aka] “dedicated to you”

In cloud computing, this same concept applies:

  • The “Public Cloud”, is a sub-tenanted environment, where you pay less, but have to share control and usability.
  • A “Private Cloud”, is still leveraging the economies of scale of a datacenter, but the servers you are on are dedicated solely to your firm’s use. This provides a significantly higher level of control and security.

Why does Public Cloud matter?

Maintaining storage needs through a public cloud provider is a viable solution for Public cloud is a viable solution for small businesses in search of third-party cloud providers to maintain their storage needs. If your data is non sensitive then you can benefit from easy-to-use security controls along with easy access. Most public cloud providers have minimum security requirements. Industries that require strict compliance requirements such as HIPPA (health insurance portability and accountability act) and PCI DSS (payment card industry data security standard) should invest in private or hybrid cloud solutions.
