Is Kubernetes IaaS or PaaS? (2025)

FAQs

Is Kubernetes a PaaS or IaaS? ›

Kubernetes is a powerful open-source container orchestration engine, upon which you could setup PaaS (Platform as a Service). Many companies offer IaaS (Infrastructure as a Service) version of Kubernetes by adding a layer of IaaS below K8. So, Kubernetes is neither IaaS nor PaaS.

A container as a Service is considered as a cloud service that is in between Infrastructure as a Service (IaaS) and Platform as a Service (PaaS). It is even termed as a subset of IaaS.

Since modern software development uses software containers, a natural and most popular choice for running modern SaaS platforms is Kubernetes, the popular container orchestrator.

Docker is a set of platform as a service (PaaS) products that use OS-level virtualization to deliver software in packages called containers. The service has both free and premium tiers. The software that hosts the containers is called Docker Engine. It was first released in 2013 and is developed by Docker, Inc.

Kubernetes infrastructure is the combination of resources (including servers, physical or virtual machines, cloud platforms and more) that supports a Kubernetes environment.

A Kubernetes service is a logical abstraction for a deployed group of pods in a cluster (which all perform the same function). Since pods are ephemeral, a service enables a group of pods, which provide specific functions (web services, image processing, etc.) to be assigned a name and unique IP address (clusterIP).

Docker provides basic networking capabilities, allowing containers to communicate with each other and the host system. However, Kubernetes offers a more advanced networking model, providing service discovery, load balancing, and network policies out of the box.

They are IaaS since Azure Storage Services provide the fundamental building blocks for cloud-based applications and services, where you get raw storage capacity (like a hard drive in the cloud) and are responsible for how you manage and utilize that capacity.

Kubernetes is neither IaaS nor PaaS. It's a container orchestration engine which makes it more like a Container As A Service or CaaS.

Kubernetes (/ˌk(j)uːbərˈnɛtɪs, -ˈneɪtɪs, -ˈneɪtiːz, -ˈnɛtiːz/, K8s) is an open-source container orchestration system for automating software deployment, scaling, and management.

What type of software is Kubernetes? ›

Kubernetes, also known as K8s, is an open source system for automating deployment, scaling, and management of containerized applications. It groups containers that make up an application into logical units for easy management and discovery.

Kubernetes is a portable, extensible, open source platform for managing containerized workloads and services, that facilitates both declarative configuration and automation. It has a large, rapidly growing ecosystem. Kubernetes services, support, and tools are widely available. This page is an overview of Kubernetes.

Kubernetes. Kubernetes is an open-source platform that provides shared services across clusters or nodes such as scaling/load balancing or monitoring and metrics, but unlike a traditional PaaS it operates at the container level so developers are not limited to the services provided.

AKS is a managed service more of a PaaS. However, the underlying Infra is exposed to CX. But, it is not recommended to manipulation of the IaaS resources. Azure Container service was more of a Iaas offering which was supporting container orchestration.

While CaaS is part of the category of other as-a-service solutions, its container focus sets it apart from platform as a service (PaaS), infrastructure as a service (IaaS), and function as a service (FaaS). CaaS falls between IaaS and PaaS in terms of features, with more options than IaaS but fewer than PaaS.

Kubernetes is an architecture that offers a loosely coupled mechanism for service discovery across a cluster. A Kubernetes cluster has one or more control planes, and one or more compute nodes.
