Yes. Kubernetes itself does not provide computing resources. It only orchestrates containers. You need machines (physical or virtual) somewhere to run the Kubernetes cluster.
There are three common ways to run Kubernetes.
Option 1: Cloud Providers (Most Common)
You rent Virtual Machines (VMs) from cloud providers like:
- Amazon AWS
- Microsoft Azure
- Google Cloud Platform (GCP)
- DigitalOcean
- Oracle Cloud
- Linode
Example on AWS:
AWS
β
βββ EC2 VM (Master/Control Plane)
βββ EC2 VM (Worker Node)
βββ EC2 VM (Worker Node)
βββ EC2 VM (Worker Node)
Install Kubernetes on these VMs.
Or, even easier…
Use a managed Kubernetes service like:
- AWS β Amazon Elastic Kubernetes Service (EKS)
- Azure β Azure Kubernetes Service (AKS)
- GCP β Google Kubernetes Engine (GKE)
These services manage much of the control plane for you.
Option 2: Your Own Servers (On-Premises)
Many large companies don’t use AWS or Azure.
They own their own servers.
Company Data Center
Server 1
Server 2
Server 3
Server 4
Install Kubernetes on these servers.
Examples:
- Banks
- Healthcare companies
- Government organizations
- Large enterprises
No cloud provider is required.
Option 3: Your Laptop (Learning)
For development and learning, Kubernetes can run locally.
Examples:
- Minikube
- kind
- Docker Desktop
Here, Kubernetes runs inside your own machine.

How Kubernetes Fits In
Think of Kubernetes like a manager.

Kubernetes decides:
- Which machine should run a container?
- How many replicas should run?
- When should a failed container restart?
- How should traffic be balanced?
But the worker machines themselves must exist somewhere.

Here:
- AWS provides the VMs.
- Kubernetes schedules Pods onto those VMs.
- Your applications run inside the Pods.
Can Kubernetes Create Servers?
Not directly.
Kubernetes cannot create physical machines by itself.
However, in cloud environments it can work with cloud services.
For example, if you configure autoscaling:

This automation relies on integration with the cloud provider’s infrastructure, not Kubernetes alone.

Interview Answer
Question: Do we need AWS or Azure to run Kubernetes?
Answer:
No. Kubernetes does not require AWS or Azure. It only needs machines to run on. Those machines can be cloud virtual machines (AWS, Azure, GCP, etc.), physical on-premises servers in a data center, or even a local laptop for development. Cloud providers are popular because they offer managed Kubernetes services such as EKS, AKS, and GKE, which simplify cluster management, but Kubernetes itself is cloud-agnostic and can run anywhere you have compute resources.
