Introduction
Do you use Google Drive for photo storage? Ever streamed a movie through Netflix? Do you send emails with Gmail? You probably already understand how to use cloud computing without even being aware of it!
At first glance, cloud computing may sound complicated and technical; however, it’s actually quite simple! Rather than keeping files/data or running programs locally (ie: Computer), all of this can take place through an internet connection via the Cloud.
The purpose of this article is to provide an explanation in layman’s terms, regarding what cloud computing is…without any degree or background knowledge.
What is Cloud Computing?
The term Cloud Computing refers to a method by which computing resources are delivered over the Internet as a service (ex. Storage, Servers, Databases, Software & Networks).
Simplified Definition
You don’t have to purchase any physical or digital hardware/software; instead, you “rent” those resources from companies (cloud providers) and are able to access them when needed.
Typical Example
Examples of traditional data storage versus cloud storage:
- Traditional – Saved files stored on your laptop computer.
- Cloud – Google drive has stored those same files and can be accessed from virtually all devices equipped with an Internet connection.
How Does Cloud Computing Work?
Cloud computing consists of utilizing servers located within Data Centers that reside inside of Cloud service provider’s (ie: Amazon, Microsoft & Google) Infrastructure/Network. At a Data Centre multiple high-powered servers will exist; each server will have been preconfigured/configured by the provider. In most instances the configuration will include both the Operating System and Applications; thus enabling Users to run any Application contained in their respective Data Centre as if the Application were running Locally (within the User’s environment).
How to Cloud Computing
- You go to the internet.
- You log into a cloud service.
- Your data and applications live on remote servers.
- You get results delivered directly to your device.
Cloud Computing Types
There are three different types of cloud computing that new users should understand.
Public Cloud
Public clouds provide services to many users and are run by a third-party provider.
Examples:
- Google Cloud
- Amazon Web Services (AWS)
- Microsoft Azure
Private Cloud
Private clouds are dedicated to one organization, allowing that organization more control and security.
Hybrid Cloud
Hybrid clouds combine both public and private cloud services.
Cloud Computing Service Models
Cloud services typically fall into three categories.
Infrastructure as a Service (IaaS)
IaaS is the standard service model for cloud computing. IaaS provides your organization with resources such as virtual servers, storage, and networking equipment.
Example:
Renting a virtual computer instead of owning one.
Platform as a Service (PaaS)
PaaS allows developers to create custom applications without having to manage the infrastructure.
Software as a Service (SaaS)
SaaS is the model for purchasing commercial-off-the-shelf (COTS) software through the internet.
Some examples of SaaS include:
- Gmail
- Dropbox
- Zoom
- Microsoft 365
Using Cloud Computing on a Daily Basis
You use cloud computing every day, and in most cases, you don’t know that you are using it!
Common Examples
- iCloud/Google Photos: Keeping Your Pictures Safe
- Netflix: Watching Movies Anywhere, Anytime
- Online Banking Apps: Manage Your Money from Home
- Google Docs: Collaborate on Documents with Friends
- Hosting Websites on the Cloud
Cloud Computing Advantages
Cloud computing is a very popular service today because it gives many advantages over traditional forms of computing.
Key Advantages
- Cost Efficiency: No more buying expensive equipment
- Scalability: Easily add or remove resources depending on your needs
- Accessibility: Can access information from anywhere via the Internet.
- Reliability: Backing up data, and being able to restore lost data in the event of a disaster, are both enabled by using cloud computing solutions.
- Security: Cloud computing provides security features such as advanced forms of encryption to protect your data against unauthorized access.
Is It Safe to Use Cloud Computing?
Security is something that many new users are concerned about when they first start using cloud computing. The major cloud computing providers invest millions of dollars each year in cyber security and typically provide a higher level of protection for data stored in the cloud than for data that is stored on personal devices.
Best Practices for Cloud Safety
- Choose Strong Passwords
- Enable 2FA
- Do Not Use Public Wi-Fi for Sensitive Activities
- Use Up-To-Date Devices
Who Should Use Cloud-Based Computing?
Cloud computing is a service that can be used by almost everyone.
Perfect for:
- Student and Educator
- Startups and Small Businesses
- Freelancers/Remote Workers
- Blogger/Webmasters
- Large Companies
FAQs about Cloud Computing
What is cloud computing in Layman’s Terms?
To put it simply, Cloud computing is accessing your software, and storing your information, over the internet, as opposed to on your computer.
Do I need to be technically inclined to use cloud services?
Not at all. Many cloud services cater towards beginners, and require little to no technical background.
Is Cloud Computing free?
There are many services that have limited storage availability on their free plans. On the paid plan, there is more available space, and additional features.
Can I access cloud data if I’m not connected to the internet?
Most of the time there are some services that allow for offline access, but the majority of cloud features are best viewed, or operated, while connected to the internet.
