Businesses are increasingly turning to the public cloud for flexibility, scalability, and cost savings; at Commercial Networks, we help organisations understand how the public cloud can transform their IT infrastructure while ensuring security and compliance.
A public cloud is a type of cloud computing where resources such AS servers, storage, and applications are delivered over the internet by third-party providers like Microsoft Azure, Amazon Web Services (AWS), and Google Cloud Platform (GCP). Unlike private clouds, which are dedicated to one organisation, public clouds are shared among multiple users, but remain secure, isolated, and easy to manage.
How Does the Public Cloud Work?
Public cloud services run on a virtualised infrastructure, dividing physical servers and storage into multiple virtual instances. Businesses can easily access and scale resources without managing the underlying hardware.
Key Features of Public Cloud:
- Multi-tenancy – multiple users share infrastructure, but data stays secure.
- On-demand resources – scale up or down instantly and pay only for what you use.
- Global access – connect from anywhere with an internet connection.
- Self-service – configure resources quickly through dashboards or APIs.
Examples of Public Cloud Services
- Infrastructure AS a Service (IaaS): AWS EC2, Microsoft Azure VMs.
- Platform AS a Service (PaaS): Google App Engine, Azure App Service.
- Software AS a Service (SaaS): Microsoft 365, Google Workspace.
Advantages of Public Cloud
- Cost Efficiency – no upfront hardware costs, pay-AS-you-go.
- Scalability – handle spikes in traffic or seasonal demand with ease.
- Accessibility – global availability for remote and distributed teams.
- Automatic Updates – providers handle security patches and upgrades.
- Innovation – access cutting-edge AI, ML, and analytics tools.
Disadvantages of Public Cloud
- Security concerns in highly regulated industries.
- Limited control over infrastructure customisation.
- Ongoing costs if usage isn’t optimised.
- Latency issues for users in remote areas with poor connectivity.
Why Choose Public Cloud?
The public cloud is a great fit for businesses that want to:
- Reduce upfront IT costs.
- Scale operations quickly.
- Access powerful tools without investing in infrastructure.
- Support remote and hybrid working models.
Public Cloud vs Private Cloud
- Public Cloud: Shared, cost-effective, highly scalable.
- Private Cloud: Dedicated, customisable, higher cost.
- Hybrid Cloud: Combines both for flexibility and control.
