Top Kubernetes as a Service (KaaS) Providers

Cloud-based platforms that offer a fully managed and scalable environment for deploying, managing, and scaling containerized applications using Kubernetes are known as managed Kubernetes services (Kubernetes-as-a-Service, or KaaS).

Kubernetes is a robust container orchestration platform, but it has a challenging learning curve and needs a lot of setup and management time. With managed Kubernetes services, the cloud provider manages the Kubernetes cluster’s ongoing maintenance, updates, scalability, and underlying infrastructure, networking, and security.

Kubernetes as a service (KaaS) provides organizations with a streamlined deployment procedure, dynamic scaling, high availability, robust security features, and cost-effectiveness. These services offer companies a quicker, more adaptable, and less expensive way to set up and run Kubernetes-based containerized applications without requiring much infrastructure expertise or resources.

Top KaaS providers:

1. Google Kubernetes Engine (GKE)

Google Cloud’s GKE is a fully-managed KaaS platform for installing, overseeing, and scaling Kubernetes-based containerized applications. It provides a simple interface for setting up and administering clusters, integration with other Google Cloud services, and features like rolling updates, automatic scaling, and multi-cluster management, making it a popular option for businesses deploying containerized applications at scale.


  • GKE offers a way for businesses to deploy and manage containerized applications without spending much money on infrastructure.
  • GKE offers a seamless end-to-end experience for deploying and managing contemporary cloud applications by integrating with other Google Cloud services like Google Cloud Storage, Cloud SQL, and BigQuery.
  • Tensor processing units (TPUs) and GPUs are supported as hardware accelerators for ML, GPGPU, HPC, and other workloads. Most features and automation abilities are present in it.


  • Although GKE offers a cost-efficient method of setting up and managing containerized applications, it may still be more expensive than competing platforms for container orchestration, especially for small-scale deployments.
  • Your server’s configuration cannot be changed. You must use either the Container OS or Ubuntu server types that they provide. Versions and kernel versions are not up to you to choose.

2. Amazon Elastic Kubernetes Service (EKS)

AWS’s Amazon Elastic Kubernetes Service (EKS) makes it easy to create, run, and grow containerized applications on AWS. In June 2018, Amazon released the Elastic Kubernetes Service, following the initial launch of its Elastic Container Service (EKS). The most popular Kubernetes as a service (KaaS) is probably this one. 


  • Amazon EKS integrates with AWS Identity and Access Management (IAM) and AWS security features, like Amazon VPC and AWS PrivateLink, to give your Kubernetes clusters and applications a secure and segregated environment.
  • You can quickly scale your Kubernetes clusters according to the demands of your applications thanks to Amazon EKS. It also integrates with AWS Auto Scaling to automatically modify resources according to demand.
  •  It boasts an SLA (Service Level Agreement: bond for performance negotiated between the cloud services provider and the client) of 99.95%. 


  • Its release velocity is slow, and it’s not accessible in all AWS regions. EKS only supports Kubernetes version 1.22, even though version 1.24 is already available.
  • You must manually install any necessary software, integrate EKS with other services, and update it; EKS does not automatically update.

3. Azure Kubernetes Service (AKS)

Microsoft Azure’s Azure Kubernetes Service (AKS) is a fully managed container orchestration service that makes it easier to develop, scale, and manage containerized applications. It offers features like automated upgrades, self-healing, and integrated security and provides a fast and effective application development and deployment method. Azure manages the infrastructure to ensure availability, scalability, and dependability.


  • AKS seamlessly integrates with other Azure services like Azure Active Directory, Azure Monitor, and Azure Virtual Network, making it simple to develop and oversee containerized applications within the Azure ecosystem.
  • It supports agile development practices like dev-ops, continuous integration (CI), and continuous delivery/continuous deployment. Integration with Azure DevOps, ACR, Azure Active Directory, and Monitoring is used.
  • Additionally, it has been the quickest to offer updated Kubernetes versions and the most proactive in releasing small patches.


  • There are roadblocks because the Azure Terraform provider fully supports not all Azure APIs.
  • In comparison to GKE and EKS, AKS is a recent invention. Numerous features are, therefore, still in the alpha or beta stages.

4. VMware Tanzu Kubernetes Grid (TKG)

VMware Tanzu Kubernetes Grid (TKG) provides businesses with a reliable and secure solution to run containerized apps across various clouds and data centers. It offers a centralized control plane that enables users to manage clusters and apps from a single console, automated patching and upgrades, disaster recovery, and integrated security.


  • Tanzu Kubernetes Grid enables businesses to deploy and manage Kubernetes clusters across various cloud providers and data centers, including AWS, Azure, and Google Cloud. It also allows businesses to select the infrastructure that best meets their requirements, whether on-premises, in the cloud, or a combination of both.
  • Tanzu Kubernetes Grid is built on top of VMware’s virtualization technology, enabling businesses to scale Kubernetes clusters quickly and efficiently to meet fluctuating demand.


  • Tanzu Kubernetes Grid installation and maintenance can be difficult, particularly for companies unfamiliar with Kubernetes or container orchestration. Deployment and maintenance can also be costly, particularly for small businesses or organizations with limited IT resources.
  • Integration: Tanzu Kubernetes Grid works well with other VMware products and services but might not be as compatible with third-party goods and services.
