Here’s a quick visual guide to get you started:
What is Public Cloud?
Public cloud is like a massive, virtual storage room and office space that anyone on the internet can rent. It’s run by companies that own huge collections of servers and storage devices. These companies let you use their space and tools for your website, app, or data, without you needing to buy and look after all that expensive equipment yourself.
Third-Party Providers
These are the companies that own and look after the public cloud. They’re responsible for making sure everything runs smoothly, from ensuring there’s enough storage for everyone’s data, to keeping the servers secure from hackers.
Internet-Based Resources
Everything in the public cloud is accessed over the internet. This means you can get to your data or use applications from anywhere, at any time, as long as you have an internet connection.
On-Demand Services
The best part about public cloud is its flexibility. You can use as much or as little of the service as you need, and only pay for what you use. This can save a lot of money compared to owning your hardware and software.
Types of Public Cloud Services
- IaaS (Infrastructure as a Service): This is like renting the land and building materials to construct your virtual office or storage space. You get the raw computing infrastructure – servers, storage, and networking – but you have to manage everything else yourself.
- PaaS (Platform as a Service): This is one step up from IaaS. It’s like renting an unfurnished office. You get the infrastructure plus some tools to help you develop and run your applications, but you still have some setting up to do.
- SaaS (Software as a Service): This is the whole package – a fully furnished, ready-to-use office space. Everything is managed for you, and you just use the software over the internet, usually through your web browser.
- FaaS (Function as a Service): Also known as serverless computing, this lets you run code in response to events without managing the underlying infrastructure. It’s like having an office that automatically adjusts itself based on how many people are working and what tasks they’re doing.
Public Cloud Examples
- AWS (Amazon Web Services): The big player in the public cloud market, offering a vast array of services from basic storage to powerful computing resources.
- Google Workspace: Google’s suite of cloud-based productivity tools, like Docs, Sheets, and Drive, that makes collaboration easy and accessible from anywhere.
- Microsoft Azure: A close competitor to AWS, Azure provides a wide range of cloud services, including AI, machine learning, and Internet of Things (IoT) capabilities.
- Dropbox: A simple, user-friendly cloud storage service that lets you store files online and access them from any device.
- Netflix: While not a public cloud provider, Netflix is a prime example of a company that leverages public cloud infrastructure (specifically AWS) to stream movies and TV shows to millions of users worldwide.
Understanding the public cloud and its services is crucial for businesses looking to scale and adapt in the digital world. By leveraging third-party providers and internet-based resources, companies can enjoy on-demand services that are scalable, cost-efficient, and globally accessible.
