What Are the Pricing Options Offered by Azure Kubernetes Service?
Azure Kubernetes Service (AKS) has a number of price options to accommodate varied workloads and business requirements. Among the cost choices are:
Aside from these pricing choices, AKS also provides a free tier with a limited number of resources and capabilities for testing and development. The free tier is charged per minute for the number and size of nodes in the cluster.
What Are the Main AKS Competitors and How Do They Differ?
Amazon Elastic Kubernetes Service (EKS)
A managed Kubernetes service from Amazon Web Services (AWS).
High availability, scalability, integration with other AWS services, and flexible pricing options.
Limited operating system support, and complex setup process, require significant AWS expertise.
Google Kubernetes Engine (GKE)
A managed Kubernetes service from the Google Cloud Platform.
High performance, integration with other Google Cloud Platform services, and easy setup process.
Higher pricing compared to other managed Kubernetes services, limited support for Windows containers.
Red Hat OpenShift
An enterprise Kubernetes platform from Red Hat.

What Are the Benefits of Using AKS over Other Competitors?
What Security Considerations Should Be Taken into Account When Using AKS?
AKS provides multiple methods for accessing the Kubernetes API, such as Azure AD, Azure AD Pod Identity, and Kubernetes RBAC. It is important to ensure that access is restricted to only authorized users or applications and that credentials are securely managed.
AKS supports Azure Virtual Network (VNet), which enables network isolation and segmentation. It is important to configure network security policies to control traffic to and from your AKS cluster.
AKS nodes can be secured using Azure Security Center, which provides visibility and control over the security of your Azure resources. It is important to ensure that nodes are regularly patched and updated to address any security vulnerabilities.
AKS supports container image signing and verification, which ensures that only trusted images are deployed to your AKS cluster. It is important to ensure that container images are scanned for vulnerabilities and that only approved images are used.
