Cloud vs. Traditional On-Premises
Contrast owning and managing physical hardware with renting capacity from a cloud provider, and learn the key benefits: elasticity, pay-as-you-go, and global reach.
Cloud vs. Traditional On-Premises is a free Cloud & IT Cert Prep lesson on CoddyKit — lesson 1 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the Cloud & IT Cert Prep learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
What Is On-Premises Infrastructure?
On-premises means a company buys and houses its own servers in its own building. Full control, but every machine must be bought and wired before anything runs.
Capital vs. Operational Expenditure
On-prem is CapEx — big one-time hardware buys. The cloud is OpEx — you just pay monthly for what you use. That switch is a big reason teams move to the cloud.
The Cloud Delivery Model
In the cloud, a cloud provider like Azure owns the data centres. You grab compute and storage over the internet and pay for what you use — they handle the hardware.
Elasticity: Scaling on Demand
Elasticity lets you add power instantly when traffic spikes and remove it when things calm down. The command below scales a set to 10 instances.
# Azure CLI: scale a VM Scale Set to 10 instances
az vmss scale \
--resource-group myRG \
--name myScaleSet \
--new-capacity 10Pay-As-You-Go Pricing
Azure bills pay-as-you-go — per second or hour, no upfront fee. Run a VM for 72 hours and you pay for exactly 72 hours. Nothing wasted on idle hardware.
Global Reach of the Cloud
Azure runs in 60+ regions worldwide, so you can host your app right next to your users. No new buildings, no waiting months — just a few clicks. 🌍
Shared Responsibility Model
The shared responsibility model splits the work: Azure secures the hardware and facilities, and you look after your app, data, and who can access it.
Speed of Innovation in the Cloud
No more waiting weeks for hardware to arrive. On Azure you can spin up a server in under two minutes, so you ship and experiment far faster.
# Provision a new Ubuntu VM in Azure in one command
az vm create \
--resource-group myRG \
--name myVM \
--image Ubuntu2204 \
--admin-username azureuser \
--generate-ssh-keysReliability and Managed Maintenance
Azure gives you built-in redundancy — failed disks get swapped automatically and Microsoft handles the patching. Enterprise-grade reliability, no infra team needed.
Security in the Cloud vs On-Premises
Thinking on-prem is always safer? Not quite. Azure pours billions into security and gives you tools like Defender for Cloud that few companies could match alone.
When On-Premises Still Makes Sense
The cloud is not always the answer. Strict data residency rules, air-gapped sites, or steady high-volume work can still make on-premises the smarter pick.

Lesson Recap
Quick recap: on-prem means CapEx and full self-management, the cloud means OpEx with pay-as-you-go and elastic scaling, and shared responsibility splits security duties.
