Rancher Enterprise Kubernetes Management is a platform that addresses the complexity of managing multiple Kubernetes clusters across different infrastructures from on-premises data centers to public clouds and edge environments. It has a centralized control plane for unified management, multi-cloud support and seamless integration with Harvester hyper-converged infrastructure (HCI). In the Kubernetes management space, Rancher sits alongside other major alternatives like Red Hat OpenShift, VMware Tanzu and the managed Kubernetes services from major cloud providers. These include cloud Kubernetes services like GKE, AKS and EKS which are now infrastructure choices. Rancher allows you to manage both its own Kubernetes distributions and cloud managed services, so you can create, import and operate clusters across different environments. When evaluating such platforms the Total Cost of Ownership (TCO) is an important aspect, where Rancher shows advantages through simplified operations and infrastructure optimization. This report will go into detail on Rancher Enterprise Kubernetes Management, its core features, pros and cons vs other solutions, Harvester HCI integration and TCO. Ultimately the suitability of Rancher depends on your organization’s specific needs, scale and existing technology investments.

Rancher Enterprise Kubernetes Management and Multi Cluster Management

Rancher is an open source container management platform and Kubernetes management platform that simplifies the complexity of deploying, managing and operating Kubernetes clusters across a wide range of infrastructure environments including on-premises data centers, public cloud platforms and edge computing deployments. For organizations running containers in production, Rancher is often referred to as a “multi-cluster Kubernetes management solution” and is a centralized administrative hub with a user accessible interface through GUIs, CLIs and APIs. A key strength of Rancher is the ability to provision new Kubernetes clusters using various engines like Rancher Kubernetes Engine (RKE), RKE2 and K3s and also the ability to import existing Kubernetes clusters regardless of the underlying provider. Creating Kubernetes clusters is a core function so you can deploy and manage container orchestration environments across different cloud providers and virtualization platforms.The platform has a full set of features and capabilities to simplify Kubernetes management at scale. Centralized Cluster Management is a core function, to create, import and manage multiple Kubernetes clusters from one dashboard. Rancher extends its reach with Multi-Cloud and Hybrid Support to manage clusters across different environments including Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), on-premises infrastructure and edge locations. Rancher supports DevOps teams and empowers DevOps teams by providing an interface to manage applications and integrate with DevOps tools to give them more autonomy and operational efficiency. For security and governance, Rancher has User and Access Control (RBAC) to centralize authentication and role-based access control for all managed clusters. Rancher allows access to kubernetes clusters hosted by different cloud providers and unified access management. The Application Catalog and Marketplace integrates with Helm to deploy pre-configured applications. Rancher also has Monitoring and Alerting capabilities with built-in tools using Prometheus and Grafana to monitor clusters and resources and ability to configure alerts. These features provide cluster visibility and cluster logging, integrated monitoring and logging tools to monitor, log and troubleshoot kubernetes clusters. Upgrade Management simplifies the complex process of upgrading kubernetes clusters. Underneath these features is Infrastructure Orchestration that automates the provisioning, management and configuration of the underlying infrastructure including kubernetes components and supporting storage and networking drivers for seamless integration. Rancher also has Fleet, a tool to automate the deployment and upgrading of workloads across multiple clusters. For multi-tenant environments, Projects allow to group multiple kubernetes namespaces into one manageable entity. Finally Rancher puts a strong emphasis on Security with features like policy enforcement across clusters, advanced RBAC controls, centralized audit logs and integration with multiple authentication providers. Rancher allows users to perform kubernetes operations like provisioning, upgrades and application management to support continuous delivery workflows and cluster administration. Note that Rancher is an open source platform currently maintained by SUSE after they acquired Rancher Labs.

Alternative Kubernetes Management Platform Options

The Kubernetes management landscape has many alternatives which can be categorized to give a better understanding of their strengths and focus areas. These categories are managed Kubernetes services by cloud vendors, enterprise Kubernetes platforms and other specialized management tools.

Among the alternatives are the managed Kubernetes services by public cloud providers. Amazon Elastic Kubernetes Service (EKS) is a fully managed service with deep integration with the AWS ecosystem. Azure Kubernetes Service (AKS) is Microsoft’s managed Kubernetes service with seamless integration with the wide range of Azure services. For AKS, there are differences in management options depending on if aks clusters are created directly through Rancher or if they are registered clusters; aks clusters created by Rancher allow more direct provisioning and configuration while registered clusters have limitations in editing and management features. Google Kubernetes Engine (GKE) by Google Cloud is known for its cluster management capabilities and tight integration with Google’s full suite of cloud services.

In the enterprise Kubernetes platforms, two big players emerge: Red Hat OpenShift is a full platform that puts a strong emphasis on developer productivity, has built-in security features and enterprise grade support. VMware Tanzu is another enterprise platform designed for hybrid and multi-cloud environments with focus on seamless integration with organizations already heavily invested in the VMware ecosystem.Beyond the big categories, there are many other Kubernetes management tools and platforms that address specific needs and use cases. When managing clusters from different sources, Rancher distinguishes between clusters it provisions directly and those it connects to as a registered cluster. Registered clusters are external Kubernetes clusters that are connected to Rancher but not provisioned by it; these registered clusters have different management options such as limited configuration edits, backup procedures and node management compared to clusters created directly through Rancher. Mirantis Kubernetes Engine (MKE) is an enterprise focused solution that emphasizes security, regulatory compliance and scalability for production level Kubernetes deployments. Canonical Charmed Kubernetes is presented as a composable, operator based Kubernetes distribution that offers full lifecycle management for both the underlying host and the in-cluster components. Platform9 offers a managed Kubernetes solution specifically for on-premises, edge computing and hybrid cloud deployments. Spectro Cloud Palette is a Kubernetes management platform for multi-cloud and hybrid deployments providing centralized control and consistent policy enforcement. Rafay Systems is a Kubernetes Operations Platform for managing Kubernetes clusters at scale across diverse cloud environments and on-premises data centers. KubeSphere is an open-source Kubernetes manager for multi-cloud and hybrid deployments offering integrated DevOps and observability functionalities. For users looking for lightweight and intuitive management, Portainer provides a user-friendly interface for managing both Docker and Kubernetes environments while Lens Desktop offers a graphical user interface to simplify the complexities of Kubernetes cluster management. k0rdent is an open-source distributed container management environment for multi-cloud and hybrid deployments. Devtron is an open-source software delivery platform for Kubernetes with strong focus on developer experience. Finally, GitOps tools like Argo CD and Flux provide a declarative approach to continuous delivery, automating deployments to Kubernetes clusters based on the desired state defined in Git repositories.

Rancher vs Alternatives Feature by Feature

When evaluating Kubernetes management platforms, a feature by feature comparison is necessary to determine the best fit for your organization. Rancher compared to the alternatives has strengths in many areas.

Rancher’s architecture is built around the rancher api server which is built on top of an embedded kubernetes api server and etcd. The rancher api server manages user management, authorization and integration with cloud infrastructure providing a secure and scalable foundation for cluster operations.Multi-Cluster Management is a key advantage for Rancher, allowing management of multiple Kubernetes clusters from a single interface, supporting many Kubernetes distributions and deployment environments. Rancher also tracks cloud infrastructure nodes, dynamically monitors and provisions nodes and storage across clusters. For node and cluster management, Rancher allows administrators to manage cluster nodes, including edit, cordon and drain nodes as needed. Registered cluster nodes in external clusters can be managed directly from the Rancher UI, supporting cordon, drain and edit operations.

Many alternatives also offer multi-cluster management but Rancher’s breadth of support is notable. Red Hat OpenShift achieves this through its Advanced Cluster Management (ACM) and VMware Tanzu through Tanzu Mission Control. Cloud-managed services like Amazon EKS have multi-cluster management through the EKS Connector and Azure AKS through Fleet Manager and Google GKE through Fleets. Other platforms like Platform9, Spectro Cloud and Rafay also emphasize multi-cluster management.

Centralized RBAC and Authentication is another area where Rancher provides value, offering robust control over user access and permissions across all managed clusters from a single point. Rancher allows organizations to manage cluster membership, a cluster administrator can add or remove nodes, manage node pools and assign roles. The cluster owner is responsible for deployment, security and policy management within clusters. Both Red Hat OpenShift and VMware Tanzu also offer strong security features in this area. Managed Kubernetes services typically integrate with the identity and access management (IAM) systems of their respective cloud providers.

Rancher’s Hybrid and Multi-Cloud Support is particularly strong due to its infrastructure-agnostic design allowing it to operate across many environments. Rancher launched clusters get full lifecycle management features including upgrades, backups and recovery. For post-provisioning management, Rancher supports editing downstream clusters, with options for existing cluster changes depending on the provisioning method—whether the cluster is Rancher-managed or registered externally. OpenShift and Tanzu also offer hybrid and multi-cloud capabilities but managed services are primarily focused on their own cloud ecosystems.The Application Catalog in Rancher simplifies the deployment of commonly used applications through its integration with Helm charts. Rancher allows deployment and automation to targeted downstream kubernetes clusters using CI/CD pipelines for easy operations. OpenShift has a similar feature with its OperatorHub, a curated set of operators for deploying and managing applications and Tanzu integrates with the VMware Marketplace for application deployment.

Ease of Use is often cited as a key advantage of Rancher, its user-friendly interface makes managing complex Kubernetes environments more accessible. Alternatives like Portainer and Lens also prioritize user experience with their interfaces.

Finally, Extensibility and Integration is crucial for any Kubernetes management platform and Rancher integrates with many DevOps tools and services. Kubernetes itself has a huge and active community that contributes many extensions and integrations.

While many platforms offer similar features, Rancher’s core strengths are in its robust multi-cluster management across many infrastructures, its focus on user-friendliness and its vendor-agnostic approach to Kubernetes distributions and infrastructure providers. This makes Rancher a very versatile solution for organizations with complex and heterogeneous Kubernetes deployments.

Cost Comparison of Kubernetes Management Platforms

The cost of a Kubernetes management platform is a critical consideration for any organization. The cost structure of Rancher and its competitors vary greatly, depending on the scale of deployment, required features and level of vendor support needed.

Rancher’s cost structure is primarily around subscription options for its enterprise offering, Rancher Prime, with pricing often based on the number of nodes under management. There may be usage-based pricing models available depending on the deployment scenario.

Managed Kubernetes Services like Amazon EKS, Azure AKS and Google GKE follow a pay-as-you-go model. Costs are primarily based on the uptime of the Kubernetes clusters and consumption of underlying infrastructure resources, including compute instances, storage volumes and network traffic. EKS and AKS have a per-cluster fee in addition to the resource consumption charges. GKE has a per-cluster fee for its Standard edition and per-vCPU for its Enterprise edition.

Red Hat OpenShift has a subscription-based pricing model, often calculated per core or per node, with multiple subscription tiers and cloud service options. For smaller teams or startups, OpenShift’s licensing costs can be a big factor.VMware Tanzu has a more complex pricing structure with multiple components and can be more expensive depending on the Tanzu modules and scale.

Mirantis Kubernetes Engine uses a subscription model priced per node per year, so more predictable cost based on the size of the Kubernetes environment.

Platform9 is a managed service with pricing based on subscription tiers depending on the service and scale of the Kubernetes deployment.

Spectro Cloud Palette has a consumption-based pricing model which can be more cost-effective than Rancher, aligns cost with actual usage and scaling patterns.

Canonical Charmed Kubernetes is free, open-source for the core components, revenue is generated through paid support subscriptions for organizations that need enterprise-level support.

Table 1: Comparative Pricing Overview

Google GKEPer cluster/vCPU hour, pay-per-pod (Autopilot)Scales with cluster size and GCP consumption; free tier available.
Mirantis Kubernetes EnginePer node per year subscriptionPredictable cost based on the number of nodes.
Platform9Managed service subscriptionPricing depends on the service level and scale.
Spectro Cloud PaletteConsumption-basedAligns with usage and scaling.
Canonical Charmed KubernetesFree (core), paid support subscriptionsLow initial cost, but support and management need consideration.

The cost of Kubernetes management solutions is highly variable depending on the pricing model, scale of deployment and features and support levels required. A thorough evaluation of these factors is necessary to make an informed decision that fits within budget and technical requirements.

Rancher and Harvester HCI Integration Deep Dive

The integration between Rancher and Harvester is a powerful combination in cloud-native infrastructure management. Harvester is an open-source hyper-converged infrastructure (HCI) software platform built on top of Kubernetes. This integration is a standard feature since Rancher v2.6.1 and allows to manage both virtual machines (VMs) and containerized workloads from a single platform.

In Rancher, the "Virtualization Management" feature allows to import and manage multiple Harvester clusters seamlessly. This integration uses Rancher’s robust authentication and role-based access control (RBAC) to provide multi-tenancy support within Harvester environments.

Rancher also has a "Harvester node driver" which is used to provision virtual machines within Harvester clusters. These VMs can then be used by Rancher to launch and manage guest Kubernetes clusters, and choose between Rancher Kubernetes Engine (RKE) and RKE2 distributions. Rancher v2.7.6 introduced an experimental feature to deploy container workloads directly onto the underlying Harvester cluster.

The typical deployment model is to install the Rancher server independently of the Harvester cluster. For evaluation purposes, the Rancher server can even be installed on a virtual machine within the Harvester environment itself.

The benefits of this integration are many: a single platform to manage VMs and containers, HCI infrastructure for Kubernetes deployments and simplification of hybrid IT environments. By combining the power of Rancher’s Kubernetes management with Harvester’s HCI capabilities, organizations can have a more streamlined and efficient way to manage their modern application landscape.

Harvester Disrupts the HCI Market

At Baytech Consulting we have been following and actively participating in the Harvester HCI evolution. As we wrote in our blog post Harvester Disrupts the HCI Market, Harvester is challenging the traditional HCI landscape in several ways.

The HCI market has been dominated by a few big vendors like VMware and Nutanix, resulting in high costs and vendor lock-in for many organizations. Harvester is disrupting this status quo by offering an open-source alternative that eliminates licensing fees and delivers robust virtualization capabilities built on proven technologies.

One of Harvester’s biggest advantages is its foundation on Kubernetes and other container orchestration software, which provides VM management without requiring users to know the underlying technologies. This makes Harvester very accessible to organizations that want to modernize their infrastructure without retraining their teams.

At Baytech we use Harvester HCI and Rancher in our own operations and have seen firsthand how this combination can transform infrastructure management. We use this experience to help our clients through their own adoption journey, addressing challenges and maximizing the benefits of this platform.

For a deeper dive into the cost savings of Harvester, read our companion article: The Cost of Harvester HCI.In that post we break down how Harvester’s open-source, Kubernetes-based architecture allows organizations to save on total cost of ownership (TCO). By eliminating licensing fees, supporting commodity hardware and integrating with Rancher, Harvester is a flexible and scalable solution in a market full of expensive proprietary options. Whether you’re evaluating your first HCI deployment or looking to cut costs on an existing infrastructure, understanding the cost of Harvester is key.

Total Cost of Ownership for Rancher Enterprise

Calculating the Total Cost of Ownership (TCO) for Rancher Enterprise Kubernetes Management involves a thorough analysis of both the cost savings and the expenses associated with its adoption and operation.

Rancher Enterprise offers several ways to save costs. Its Simplified Management leads to reduced operational overhead and increased efficiency through centralized control and automation of Kubernetes clusters. This simplification also contributes to Increased Developer Productivity by providing streamlined workflows and integrated tools so developers can focus on application development rather than infrastructure management. Rancher’s Infrastructure Optimization comes from being able to run on multiple infrastructures, including bare metal servers, which reduces the costs of traditional virtualization layers like VMware. The platform’s No Vendor Lock-in allows organizations to choose their underlying infrastructure and Kubernetes distributions, mitigating the cost escalations of proprietary solutions. Plus, its integration with Harvester allows to reduce the reliance on expensive proprietary HCI solutions, using open-source alternatives.

However, several cost factors must also be considered. These include the Subscription Costs for Rancher Prime, which are typically based on the number of nodes or other usage metrics. Organizations must also factor in the Infrastructure Costs of running the Rancher management plane, including the necessary compute, memory and storage resources. Operational Costs, particularly personnel costs for managing both Rancher and the Kubernetes clusters it manages, including the need for specialized training and expertise, are also significant. As we mentioned in the Rancher Open Source post, Hidden Costs such as the need for dedicated controllers for isolation and the effort to ensure robust security and governance should not be overlooked.

A Forrester Total Economic Impact (TEI) report has shown a strong return on investment (ROI) for organizations deploying Rancher Prime, so the benefits may outweigh the costs. Ultimately a TCO analysis for Rancher Enterprise should take into account the scale, complexity and strategic objectives of an organization’s Kubernetes deployments.## TCO Comparison: Rancher Enterprise vs. Alternatives

Comparing the Total Cost of Ownership (TCO) of Rancher Enterprise with its alternatives requires a deep understanding of the various cost factors for each platform. Research suggests Red Hat OpenShift may have higher infrastructure costs, while VMware Tanzu’s licensing model can add to the overall TCO. Managed Kubernetes services like EKS, AKS and GKE offload operational complexity but have their own cost structure tied to cloud resource consumption. Spectro Cloud Palette positions itself as a more cost-effective alternative to Rancher and Rafay aims to lower TCO with its Software-as-a-Service (SaaS) model. Platform9’s TCO analysis has shown potential savings compared to a “Do-It-Yourself” (DIY) approach to Kubernetes management.

It’s important to recognize that the most cost-effective option from a TCO standpoint depends on the specific use case, the scale of Kubernetes deployments and the unique priorities of the organization. Factors such as the need for specific features (e.g. OpenShift’s developer tools, Tanzu’s deep VMware integration), the level of management (fully managed vs self-managed) and existing infrastructure investments all play a big role in determining the overall cost.

Table 2: Comparative TCO Considerations

PlatformPotential TCO AdvantagesPotential TCO Disadvantages
RancherSimplified management, infrastructure optimization, no vendor lock-in, Harvester integrationSubscription costs, infrastructure for management plane, need for expertise.
Red Hat OpenShiftStrong developer tools, built-in securityCan be expensive, higher infrastructure demands.
VMware TanzuIntegration with VMware ecosystemComplex licensing, potentially high cost, vendor lock-in for VMware users.

Azure AKSManaged service, Azure integrationCosts scale with Azure usage, per-cluster fees.
Google GKEManaged service, advanced cluster managementCosts scale with GCP usage, per-cluster/vCPU fees.
Mirantis Kubernetes EnginePredictable per-node pricingMight lack some advanced features of other platforms.
Platform9Managed service across environmentsPricing depends on scale and features.
Spectro Cloud PalettePotentially lower cost than Rancher, full-stack lifecycle managementCommercial product, might have a learning curve.
Canonical Charmed KubernetesLow initial cost (open source)Requires in-house expertise for management and support if not using paid subscriptions.

Given the many pricing models and variables at play, a direct TCO comparison across all platforms is impossible. Organizations should do their own analysis based on their specific needs and use vendor provided TCO calculators to get more accurate estimates.

Infrastructure and Operational Costs for Rancher

Deploying and managing Kubernetes with Rancher has its own infrastructure and operational costs to consider.

A fundamental requirement is a dedicated Kubernetes cluster, or at least a single node Kubernetes setup for initial testing, to host the Rancher management plane. The nodes in this Rancher management cluster require a certain amount of resources, CPU and memory, and these can scale up depending on the number of downstream Kubernetes clusters and total number of nodes being managed by Rancher. Additionally, specific network ports need to be open for communication between the Rancher server nodes, the downstream Kubernetes clusters and any external services Rancher integrates with, such as authentication providers and node drivers.

Beyond the infrastructure itself, operational costs are a big part of the TCO. These costs include the Personnel costs of hiring or training administrators and engineers with the skills to manage both Kubernetes and the Rancher platform. Setting up and maintaining Monitoring and Logging solutions for the Rancher management plane and all the downstream clusters is another operational cost. Ensuring Security, through the implementation and ongoing management of RBAC policies and network configurations, is also an operational cost. Upgrades and Maintenance for both Rancher and the managed Kubernetes clusters require time and resources, so that’s an operational cost. Finally, the effort and cost of Integration with existing DevOps tools and broader IT infrastructure should be considered. When Rancher is used with hyper-converged infrastructure solutions like Harvester, organizations should also consider resource implications, such as increased storage consumption due to data replication mechanisms in HCI architectures.

While Rancher simplifies many aspects of Kubernetes management, organizations need to plan for the underlying infrastructure to run the Rancher management plane and budget for the ongoing operational costs of a multi-cluster Kubernetes environment. Good capacity planning and skilled personnel are key to both performance and cost efficiency.

Kubernetes

Kubernetes is an open-source container orchestration platform that has become the industry standard for automating the deployment, scaling and management of containerized applications. Originally developed by Google and now maintained by the Cloud Native Computing Foundation (CNCF), Kubernetes allows organizations to run applications across a wide range of environments, from traditional on-premises data centers to public clouds and edge locations.

One of the platform’s key strengths is its ability to manage multiple Kubernetes clusters, so organizations can orchestrate workloads at scale and across geographically distributed sites. Kubernetes automates complex operational tasks such as rolling updates, self-healing and resource optimization, so it’s an essential tool for modern DevOps teams. With features like automated deployment and dynamic scaling, Kubernetes simplifies the management of containerized applications, so businesses can respond to changing demands and maintain high availability in even the most complex environments.

As organizations adopt microservices architectures and deploy workloads to the edge, Kubernetes provides the flexibility and control to manage these distributed, multi-cluster environments. Its robust ecosystem and active community support make Kubernetes the foundation for cloud-native application delivery and container orchestration.

Kubernetes Cluster Management

Kubernetes cluster management is the process of creating, configuring and maintaining groups of machines—known as Kubernetes clusters—that work together to run containerized applications. As organizations use more containers, the need to manage multiple Kubernetes clusters across different environments becomes critical. This is especially true for enterprises in hybrid or multi-cloud scenarios or those deploying workloads to edge locations.

Managing multiple Kubernetes clusters is complex, especially when clusters are created with different Kubernetes distributions or installers. Rancher solves this problem by providing a centralized management platform to manage both new and existing Kubernetes clusters, regardless of their origin. With Rancher, organizations can unify their Kubernetes cluster management under a single control plane, simplify operations, improve visibility and reduce the risk of configuration drift.

Rancher’s platform supports the full lifecycle of Kubernetes clusters, from initial provisioning to ongoing maintenance and upgrades. It allows administrators to manage existing Kubernetes clusters created with any distribution, as well as provision new clusters tailored to specific requirements. This centralized approach to Kubernetes management not only improves operational efficiency but also ensures consistent governance and security across all environments.

Access Control

Access control and security are key to Kubernetes cluster management, especially when managing multiple Kubernetes clusters across different environments. Kubernetes natively provides role-based access control (RBAC), so administrators can define granular permissions for users and service accounts within each cluster. But as organizations scale and manage multiple clusters, maintaining consistent access policies and secure authentication becomes more complex.

Rancher enhances Kubernetes security by providing centralized authentication and access control across all managed clusters. Through its single pane of glass, administrators can implement and enforce role-based access control policies so only authorized users have access to sensitive cluster resources. Rancher also supports integration with external authentication providers, such as Active Directory and other identity management solutions, so organizations can use existing user directories for seamless, centralized authentication.

Beyond user access, Rancher provides tools to manage cluster membership, node pools and storage classes, all essential for keeping Kubernetes clusters secure. By consolidating access control and security management, Rancher reduces operational complexity and lets organizations maintain strong security across their entire Kubernetes landscape.

Kubernetes Cluster Deployment

Deploying Kubernetes clusters is a critical step to running containerized applications at scale. Kubernetes cluster deployment is the process of creating and configuring clusters to meet workload requirements, whether on-premises, in the cloud or at edge locations. Rancher simplifies this process by providing a user-friendly platform to create new Kubernetes clusters and import existing Kubernetes clusters created with any distribution or installer.

With Rancher Kubernetes Engine (RKE), organizations can provision clusters tailored to their needs, choosing from a range of Kubernetes distributions and infrastructure platforms. The platform supports multiple cluster configurations, including node roles, Kubernetes versions, network plugins and security policies so administrators can fine tune deployments for performance and compliance.

Rancher’s flexibility extends to managing existing Kubernetes clusters, so organizations can bring clusters created outside of Rancher under management. This is especially useful for enterprises with heterogeneous environments or those migrating workloads between cloud providers and on-premises infrastructure. By simplifying the deployment and configuration of Kubernetes clusters, Rancher lets organizations accelerate their cloud-native journey while maintaining control, security and operational consistency across all environments.

Conclusion and Recommendations

In summary, Rancher Enterprise Kubernetes Management is a robust and flexible platform with strengths in managing multiple Kubernetes clusters, supporting hybrid and multi-cloud environments and integrating with Harvester HCI.
