Cloud Computing: Function and Risks

"Oh it's in the Cloud."

We refer to the Cloud all the time, but what is it?

Cloud computing is renting resources, like storage space, on another company's computers. You only pay for what you use. The company providing these services is referred to as a Cloud Provider.

Cloud Computing allows users to benefit from new technologies, without the need for expertise to use them.

Some examples of Cloud Computing include: streaming services (Netflix), gaming (Fortnite), and document/email services (Gmail, Google Docs).

1. Reduce Capital Expenses 

Companies can utilize storage and computing resources from the Cloud provider, so they do not have to buy or maintain their own.

2. Improve System Reliability

Cloud Providers guarantee a certain level of service through contracts known as Service Level Agreements (SLA) that make it easier for their customers to provided uninterrupted service.

There is no more delay that could be associated with geographical distance (for a technician to go on site), or lead delivery time for replacement equipment. The Cloud provider takes care of the hardware backup strategies and maintenance updates. 

3. Greater Flexibility and Scalability

Cloud computing is elastic and scalable; users can increase/decrease resources as needed. This allows a business to grow or shrink to adapt to market demands.

4. Redundancy 

Redundancy is having more than one of something in case the first instance fails. Cloud computing stores data in multiple places, so that even if one server has an issue, the data will remain intact.

1. Downtime

Service outages are always possible, and can occur without warning.

2. Security

Storing data and important files on external service providers creates risk. Data can be hacked or compromised.

3. Limited Control

Since the Cloud infrastructure is entirely owned, managed, and monitored by the service provider, you may have limited control as a user.

4. Difficult to Change Providers

Organizations may find it difficult to migrate their services from one vendor to another.
