The"public cloud" is freely available and accessible to everyone via the Internet. These cloud services are provided by various external companies around the world. The three largest public and international cloud providers include Amazon Web Services (AWS), Microsoft Azure and Google Cloud Platform.

The"private cloud" makes its cloud resources available exclusively to certain companies or organizations, and unlike the "public cloud", it is not accessible to the general public.

The"Hybrid Cloud" combines the advantages of the "Private Cloud" and the "Public Cloud" and thus offers flexibility and security at the same time.

"Multi-cloud" is the use of multiple cloud computing and storage services in a single heterogeneous architecture.

What does Amazon EKS Anywhere offer?

It's almost hard to believe, but it's true: To install Amazon EKS Anywhere, customers/interested parties don't have to sign up or register with AWS as usual or sign a separate contract. The source code is made available by the company on GitHub for anyone to try out.

Amazon EKS Anywhere is based on EKS Distro, the open source distribution that helps you create reliable and secure clusters. EKS Anywhere is also open source, but unlike EKS Distro, customers can purchase official support from Amazon if they wish. Because it is managed and supported by AWS, it is a very idiosyncratic distribution. Components such as the Cilium network plugin can be used and not replaced with other plugins. However, CNI-compatible plugins remain freely selectable with the EKS distribution.

Support costs money

Unfortunately, the whole thing is still not quite cheap including support: AWS customers can purchase an EKS Anywhere support subscription for one year at a hefty price of $24,000 per cluster or directly for three years at a price of $18,000 per cluster per year. Another requirement or hurdle is an active Enterprise Support plan, which starts at $15,000 per month. Wow.

At launch, EKS Anywhere supports several plugins offered by AWS partners and the Cloud Native Ecosystem. EKS Anywhere can be installed on a Mac or on Linux to deploy clusters appropriately in development and test environments. It takes advantage of Docker desktop and KIND environment on macOS and Docker Community Engine installations in Ubuntu. However, for active production environments, customers need a VMware vSphere 7.0 or higher to deploy and administer clusters.

Dependencies complicate the use in other environments

Based on the Cluster API interface and the Cluster API provider model, Amazon EKS is dependent on VMware vSphere. This dependency makes it difficult to deploy in other environments, including cloud-based infrastructure services such as Amazon EC2, Google Compute Engine, or Azure VMs. With VMware basically available on the public cloud platforms, it will be very exciting to see if Amazon EKS Anywhere can be deployed in these environments.

Management of external clusters via Connector

EKS Console, the web-based interface originally introduced for managing EKS clusters in the cloud, now also supports registering and managing external clusters running Amazon EKS Anywhere.

Called EKS Connector, the tool can be used to manage external Kubernetes clusters, such as Google Kubernetes Engine or Azure Kubernetes Service. This Connector feature is currently still in the publicly available testing phase.

With Amazon EKS Anywhere, AWS is now entering the hybrid and multi-cloud business as an official big player, competing with products from Google and Microsoft.

Kubernetes Services: AWS vs. Azure vs. Google Cloud

Cloud service providers such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP) play an important role in providing advanced capabilities for enterprises to manage their Kubernetes architecture.
